74HC174; 74HCT174
Hex D-type flip-flop with reset; positive-edge trigger
Rev. 5 — 26 February 2021
Product data sheet
1. General description
The 74HC174; 74HCT174 are hex positive edge-triggered D-type flip-flops with individual data
inputs (Dn) and outputs (Qn). The common clock (CP) and master reset (MR) inputs load and reset
all flip-flops simultaneously. The D-input that meets the set-up and hold time requirements on the
LOW-to-HIGH clock transition is stored in the flip-flop and appears at the Q output. A LOW on MR
causes the flip-flops and outputs to be reset LOW. Inputs include clamp diodes. This enables the
use of current limiting resistors to interface inputs to voltages in excess of VCC.

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

Product data sheet
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Nexperia 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 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

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.
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.
