74LVX373 Datasheet, PDF (2/8 Pages) Fairchild Semiconductor – Low Voltage Octal Transparent Latch with 3-STATE Outputs

Functional Description
The LVX373 contains eight D-type latches with TRI-STATE
standard outputs When the Latch Enable (LE) input is
HIGH data on the D_n inputs enters the latches In this con-
dition the latches are transparent i e a latch output will
change state each time its D input changes When LE is
LOW the latches store the information that was present on
the D inputs a setup time preceding the HIGH-to-LOW tran-
sition of LE The TRI-STATE standard outputs are con-
trolled by the Output Enable (OE) input When OE is LOW
the standard outputs are in the 2-state mode When OE is
HIGH the standard outputs are in the high impedance mode
but this does not interfere with entering new data into the
latches
