• Manufacturer Part Number: 74ALVC16373
• Description: Low Voltage 16-Bit Transparent Latch with 3.6V Tolerant Inputs and Outputs
• Manufacturer: Fairchild Semiconductor

Functional Description
The 74ALVC16373 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
byte. When the Latch Enable (LE
