Programmable timer
Rev. 3 — 25 November 2021
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.

[1] 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
[2] 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.

11. 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 Ω at VDD = 5 V,
300 Ω at VDD = 10 V and 200 Ω 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 kΩ ≤ RTC ≤ 1 MΩ.
