DESCRIPTION
The MB2377 high-performance BiCMOS
device combines low static and dynamic
power dissipation with high speed and high
output drive.
The MB2377 has two 8-bit, edge triggered
registers, with individual D inputs and Q
outputs. The common buffered clock (1CP or
2CP) input will load a set of eight flip-flops
simultaneously when the corresponding
Enable (1E or 2E) input is Low.
The registers are 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 nE inputs must be stable one setup time
prior to the Low-to-High clock transition for
predictable operation.
