description

These 8-bit latches feature 3-state outputs

designed specifically for driving highly capacitive

or relatively low-impedance loads. They are

particularly suitable for implementing buffer

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

working registers.

The eight latches of the ′F373 are transparent

D-type latches. While the latch-enable (LE) input

ishigh, theQoutputswillfollowthedata(D)inputs.

When the latch enable is taken low, the Q outputs

are latched at the logic levels set up at the D

inputs.

A buffered output-enable (OE) input can be used

to place the eight outputs in either a normal

logic state (high or low logic levels) or a

high-impedance state. In the high-impedance

state, the outputs neither load nor drive the bus

lines significantly. The high-impedance state and

increased drive provide the capability to drive bus

lines without need for interface or pullup

components.

The output-enable (OE) input does not affect the internal operations of the latches. Old data can be retained

or new data can be entered while the outputs are in the high-impedance state.

The SN74F373 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54F373 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74F373 is characterized for operation from 0°C to 70°C.
