74HC377; 74HCT377
Octal D-type flip-flop with data enable; positive-edge trigger
Rev. 4 — 24 February 2016
Product data sheet
1. General description
The 74HC377; 74HCT377 is an octal positive-edge triggered D-type flip-flop. The device
features clock (CP) and data enable (E) inputs. When E is LOW, the outputs Qn assume
the state of their corresponding Dn inputs that meet the set-up and hold time requirements
on the LOW-to-HIGH clock (CP) transition. Input E must be stable one set-up time prior to
the LOW-to-HIGH transition for predictable operation. Inputs include clamp diodes that
enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
2. Features and benefits
Common clock and master reset
Eight positive edge-triggered D-type flip-flops
Complies with JEDEC standard no. 7A
Input levels:
For 74HC377: CMOS level
For 74HCT377: TTL level
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V.
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C

Product data sheet
Suitability for use — Nexperia products are 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 a Nexperia product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. Nexperia and its suppliers accept no liability for
inclusion and/or use of Nexperia products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
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 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.
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.
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.
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

applying the customer’s general terms and conditions with regard to the
purchase of Nexperia products by customer.
