DESCRIPTION
The UT54ACS374 and the UT54ACTS374 are non-inverting
octal D type flip-flops with three-state outputs designed for driv-

The eight flip-flops are edge triggered D-type flip-flops. On the

positive transition of the clock the Q outputs will follow the data

An output-control input (OC) places the eight outputs in either
a normal logic state (high or low logic level) or a high-imped-
ance state. The high-impedance third state and increased drive
provide the capability to drive the bus line in a bus-organized

The output control OC does not affect the internal operations of
