74ABT377A
Octal D-type flip-flop with enable
The 74ABT377A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT377A has 8 edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common buffered clock (CP) input loads all flip-flops simultaneously when the Enable (E) input is Low.
The register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop?s Q output.
The E input must be stable one setup time prior to the Low-to-High clock transition for predictable operation.
