• Manufacturer Part Number: 74lcxh16373
• Description: Voltage 16-bit Transparent Latch With Bushold
• Manufacturer: Fairchild Semiconductor

Functional Description
The LCXH16373 contains sixteen D-type latches with
3-STATE standard 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
