DESCRIPTION
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.
