DESCRIPTION  
The M54/74HC375 is a high speed CMOS QUADD  
TYPE LATCH fabricated in silicon gate C2MOS  
technology. It has the same high speed perform-  
ance of LSTTL combinedwithtrue CMOSlowpower  
consumption. It contains two groups of 2-bit latches  
.
.
controlled by an enable input (G1 2 or G3 4).  
These two latch groups can be used in the different  
circuits. Each latch has Q and Q outputs (1Q to 4Q  
and 1Q to 4Q). The data applied to the data input is  
transferred to the Q and Q outputs when the enable  
input is taken high and the outputs will follow the  
data input as long as the enable input is kept high.  
When the enable input is taken low, the information  
data applied to the data input at that time is retained  
at the outputs.  
All inputs are equipped with protection circuits  
against static discharge and transient excess volt-  
age.
