DESCRIPTION
The 74AHC/AHCT377 D-type flip-flops are high-speed
silicon-gate CMOS devices and are pin compatible with
low power Schottky TTL (LSTTL). They are specified in
compliance with JEDEC standard No. 7A.
The 74AHC/AHCT377 devices have eight edge-triggered,
D-type flip-flops with individual D inputs and Q outputs.
A common clock (CP) input loads all flip-flops
simultaneously when the data enable (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 (Q
n
) of the flip-flop.
TheE input must be stable only one set-up time prior to the
LOW-to-HIGH transition for predictable operation.
