Functional Description

The

74ALVCH162373

contains

sixteen edge

D-type

latches with 3-STATE outputs. The device is byte controlled

with each byte functioning identically, but independent of

the other. Control pins can be shorted together to obtain full

16-bit operation. The following description applies to each

transparent, i.e., a latch output will change state each time

information that was present on the I inputs a setup time

in the high impedance mode but this does not interfere with

entering new data into the latches.
