• Manufacturer Part Number: 74lvth16373gx
• Description: Low Voltage 16-bit Transparent Latch With 3-state Outputs
• Manufacturer: Fairchild Semiconductor

Functional Description
The LVT16373 and LVTH16373 contain sixteen D-type
latches with 3-STATE standard outputs. The device is byte
controlled with each byte functioning identically, but inde-
pendent 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
HIGH, data on the D
the latches are transparent, i.e, a latch output will change
states each time its D input changes. When LE
