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.
