Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 0.6/0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT377T is an 8-bit wide octal designed with eight edge-
triggered D-type flip-flops with individual D inputs and O outputs.
When Clock Enable (CE) is LOW, the common buffered Clock
(CP) loads all flip-flops simultaneously. The register is fully edge-
triggered. D input state, one setup time before the LOW-to-HIGH
clock transition, is transferred to the corresponding flip-flop’s O
output. The CE input must be stable only one setup time prior to
the LOW-to-HIGH transition for predictable operation.
