74HC377-Q100; 74HCT377-Q100
Octal D-type flip-flop with data enable; positive-edge trigger
Rev. 1 — 21 October 2013
Product data sheet
1. General description
The 74HC377-Q100; 74HCT377-Q100 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 V
CC
.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
