DESCRIPTION

The UT54ACS373 and the UT54ACTS373 are 8-bit latches

with three-state outputs designed for driving highly capacitive

or relatively low-impedance loads. The device is suitable for

buffer registers, I/O ports, and bidirectional bus drivers.

V_DD

V_SS

The eight latches are transparent D latches. While the enable

the enable is taken low, the Q outputs will be latched at the levels

that were set up at the D inputs.

An output-control input (OC) places the eight outputs in either

a normal logic state (high or low logic levels) 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

system without need for interface or pull-up components.

LOGIC SYMBOL

The output control OC does not affect the internal operations of

the latches. Old data can be retained or new data can be entered

while the outputs are off.

The devices are characterized over full military temperature

range of -55°C to +125°C.
