74HC574; 74HCT574
Octal D-type flip-flop; positive edge-trigger; 3-state
Rev. 9 — 20 October 2022
Product data sheet
1. General description
The 74HC574; 74HCT574 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs.
The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state
of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH
clock (CP) transition. 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 flip-flops. Inputs include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC
.

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

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

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
