Octal D-type flip-flop with data enable; positive-edge trigger
Rev. 1 — 3 December 2013
Product data sheet
1. General description
The 74AHC377-Q100; 74AHCT377-Q100 is a high-speed Si-gate CMOS device and is
pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with
JEDEC standard No. 7-A. The 74AHC377-Q100; 74AHCT377-Q100 has eight
edge-triggered, D-type flip-flops with individual D inputs and Q outputs. A common clock
input (CP) loads all flip-flops simultaneously when the data enable input (E) is LOW. The
state of each D input, one set-up time before the LOW-to-HIGH clock transition, is
transferred to the corresponding output (Qn) of the flip-flop. The E input is only required to
be stable one set-up time prior to the LOW-to-HIGH transition for predictable operation.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits

Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2]
tpd is the same as tPLH and tPHL.
[3]
CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD  VCC2  fi  N + (CL  VCC2  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;
(CL  VCC2  fo) = sum of the outputs.

Product data sheet
Suitability for use in automotive applications — This NXP
Semiconductors product has been qualified for use in automotive
applications. Unless otherwise agreed in writing, the product is 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 an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors 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. NXP Semiconductors 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 NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors 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.
NXP Semiconductors 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 NXP
Semiconductors 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). NXP 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 — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
