74HC377; 74HCT377
Octal D-type flip-flop with data enable; positive-edge trigger
Rev. 5 — 25 February 2021
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.

PD = CPD x VCC x fi + Σ (CL x VCC x fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;

Σ (CL x VCC x fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in V.

Definitions
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.
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.

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
