description  
GND 10  
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 ’HC373 are transparent  
D-type latches. While the latch-enable (LE) input  
is high, the Q outputs follow the data (D) inputs.  
When LE is taken low, the Q outputs are latched  
at the levels that were set up at the D inputs.

6D  
An output-enable (OE) input places the eight  
outputs in either a normal logic state (high or low  
logic levels) or the 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  
interface or pullup components.  
OE 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 SN54HC373 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74HC373 is characterized for operation from –40°C to 85°C.
