U74AHC377
OCTAL D-TYPE FLIP-FLOPS WITH DATA ENABLE POSITIVE-EDGE TRIGGER
DESCRIPTION
The U74AHC377 is a high-speed Si-gate CMOS device and is compatible with low-power
Schottky TTL (LSTTL).
The U74AHC377 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs.
A common clock input (CLK) loads all flip-flops simultaneously when the data enable
input ( EN ) 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 EN input is only required to be stable one set-up time prior to the LOW-to-HIGH transition for predictable operation.
