SEMICONDUCTOR TECHNICAL DATA

CASE 732–03  
High–Performance Silicon–Gate CMOS

The MC54/74HC373A is identical in pinout to the LS373. The device  
inputs are compatible with standard CMOS outputs; with pullup resistors,  
they are compatible with LSTTL outputs.  
These latches appear transparent to data (i.e., the outputs change  
asynchronously) when Latch Enable is high. When Latch Enable goes low,  
data meeting the setup and hold time becomes latched.

N SUFFIX  
PLASTIC PACKAGE  
CASE 738–03  
1
The Output Enable input does not affect the state of the latches, but when  
Output Enable is high, all device outputs are forced to the high–impedance  
state. Thus, data may be latched even when the outputs are not enabled.  
The HC373A is identical in function to the HC573A which has the data  
inputs on the opposite side of the package from the outputs to facilitate PC  
board layout.
