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.
