74HC373; 74HCT373
Octal D-type transparent latch; 3-state
Rev. 8 — 6 September 2021
Product data sheet
1. General description
The 74HC373; 74HCT373 is an octal D-type transparent latch with 3-state outputs. The device
features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs
enter the latches. In this condition the latches are transparent, a latch output will change each time
its corresponding D-input changes. When LE is LOW the latches store the information that was
present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE
causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not
affect the state of the latches. Inputs include clamp diodes. This enables the use of current limiting
resistors to interface inputs to voltages in excess of VCC
.

[5] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC 2 × fi × N + Σ(CL × VCC 2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(CL × VCC 2 × fo) = sum of outputs.

Customers are responsible for the design and operation of their applications
and products using Nexperia products, and Nexperia accepts no liability for
any assistance with applications or customer product design. It is customer’s
sole responsibility to determine whether the Nexperia product is suitable
and fit for the customer’s applications and products planned, as well as

Nexperia 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 Nexperia 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). Nexperia does not accept any
liability in this respect.
[2] The term 'short data sheet' is explained in section "Definitions".

changed since this document was published and may differ in case of
multiple devices. The latest product status information is available on
the internet at https://www.nexperia.com.
Definitions
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.
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. Nexperia 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 Nexperia sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Terms and conditions of commercial sale — Nexperia products are
sold subject to the general terms and conditions of commercial sale, as
published at http://www.nexperia.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. Nexperia hereby expressly objects to applying the customer’s general
terms and conditions with regard to the purchase of Nexperia products by
customer.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and customer have explicitly
agreed otherwise in writing. In no event however, shall an agreement be
valid in which the Nexperia product is deemed to offer functions and qualities
beyond those described in the Product data sheet.
No offer to sell or license — Nothing in this document may be interpreted
or construed as an offer to sell products that is open for acceptance or the
grant, conveyance or implication of any license under any copyrights, patents
or other industrial or intellectual property rights.
Export control — This document as well as the item(s) described herein
may be subject to export control regulations. Export might require a prior
authorization from competent authorities.

Limited warranty and liability — Information in this document is believed
to be accurate and reliable. However, Nexperia 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. Nexperia takes no responsibility
for the content in this document if provided by an information source outside
of Nexperia.
Non-automotive qualified products — Unless this data sheet expressly
states that this specific Nexperia product is automotive qualified, the
product is not suitable for automotive use. It is neither qualified nor tested in
accordance with automotive testing or application requirements. Nexperia
accepts no liability for inclusion and/or use of non-automotive qualified
products in automotive equipment or applications.
In no event shall Nexperia 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.
In the event that customer uses the product for design-in and use in
automotive applications to automotive specifications and standards,
customer (a) shall use the product without Nexperia’s warranty of the
product for such automotive applications, use and specifications, and (b)
whenever customer uses the product for automotive applications beyond
Nexperia’s specifications such use shall be solely at customer’s own risk,
and (c) customer fully indemnifies Nexperia for any liability, damages or failed
product claims resulting from customer design and use of the product for
automotive applications beyond Nexperia’s standard warranty and Nexperia’s
product specifications.
Notwithstanding any damages that customer might incur for any reason
whatsoever, Nexperia’s aggregate and cumulative liability towards customer
for the products described herein shall be limited in accordance with the
