74LVT16373MEAX

Low Voltage 16-Bit Transparent Latch with 3-STATE Outputs

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 (LEn) input is

HIGH, data on the Dn enters the latches. In this condition

the latches are transparent, i.e, a latch output will change

states each time its D input changes. When LEn is LOW,

Logic Diagrams

the latches store information that was present on the D

inputs a setup time preceding the HIGH-to-LOW transition

of LEn. The 3-STATE standard outputs are controlled by

the Output Enable (OEn) input. When OEn is LOW, the

standard outputs are in the 2-state mode. When OEn is

HIGH, the standard outputs are in the high impedance

mode but this does not interfere with entering new data into

the latches.
