Product data sheet
1. General description
The HEF4541B-Q100 is a programmable timer. It consists of a 16-stage binary counter,
an integrated oscillator to be used with external timing components, an automatic
power-on reset and output control logic. The external components RTC and CTC
determines the frequency of the oscillator within the frequency range 1 Hz to 100 kHz. An
external clock signal at input RS can replace the oscillator. The timer advances on the
positive-going transition of RS. A LOW on the auto reset input (AR) and a LOW on the
master reset input (MR) enables the internal power-on reset. A HIGH level at input MR
resets the counter independent on all other inputs. Resetting, disables the oscillator to
provide no active power dissipation.
A HIGH at input AR turns off the power-on reset to provide a low quiescent power
dissipation of the timer. The 16-stage counter divides the oscillator frequency by 28, 210,
213 or 216 depending on the state of the address inputs (A0, A1). The divided oscillator
frequency is available at output O. The phase input (PH) features a complementary output
signal. When the mode select input (MODE) is LOW the timer is a single transition timer
and when HIGH the timer is a 2n frequency divider.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.

[2] For correct power-on reset, the supply voltage should be above 8.5 V. For VDD < 8.5 V, disable the auto reset and connect AR to VDD
.
[3] The timer is initialized on a reset pulse and the output changes state after 2n-1 counts and remains in that state (latched). A master reset
or a LOW to HIGH transition on the MODE input, resets this latch.

12. Application information
RC oscillator timing component limitations
RTCCTC determines the oscillator frequency, provided RTC << RS and RSC2 << RTCCTC
.
The function of RS is to minimize the influence of the forward voltage across the input
protection diodes on the frequency. The stray capacitance C2 should be kept as small as
possible. In consideration of accuracy, CTC must be larger than the inherent stray
capacitance. RTC must be larger than the LOCMOS ‘ON’ resistance in series with it, which
typically is 500 at VDD = 5 V, 300 at VDD = 10 V and 200 at VDD = 15 V.
The recommended values for these components to maintain agreement with the typical
oscillation formula are: CTC 100 pF, up to any typical value, 10 k RTC 1 M.

Suitability for use in automotive applications — This NXP
16.2 Definitions
Semiconductors product has been qualified for use in automotive
applications. Unless otherwise agreed in writing, the product is not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer's own
risk.
Draft — The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. NXP Semiconductors does not give any
representations or warranties as to the accuracy or completeness of
information included herein and shall have no liability for the consequences of
use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
16.3 Disclaimers
Limited warranty and liability — Information in this document is believed to
be accurate and reliable. However, NXP Semiconductors does not give any
representations or warranties, expressed or implied, as to the accuracy or
completeness of such information and shall have no liability for the
consequences of use of such information. NXP Semiconductors takes no
responsibility for the content in this document if provided by an information
source outside of NXP Semiconductors.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
In no event shall NXP Semiconductors be liable for any indirect, incidental,
punitive, special or consequential damages (including - without limitation - lost
profits, lost savings, business interruption, costs related to the removal or
replacement of any products or rework charges) whether or not such
damages are based on tort (including negligence), warranty, breach of
contract or any other legal theory.
Notwithstanding any damages that customer might incur for any reason
whatsoever, NXP Semiconductors’ aggregate and cumulative liability towards
customer for the products described herein shall be limited in accordance
with the Terms and conditions of commercial sale of NXP Semiconductors.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. NXP Semiconductors hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.
Right to make changes — NXP Semiconductors reserves the right to make
changes to information published in this document, including without
limitation specifications and product descriptions, at any time and without
notice. This document supersedes and replaces all information supplied prior
to the publication hereof.
