MC74LCX373_13 Datasheet, PDF (1/9 Pages) ON Semiconductor – Low-Voltage CMOS Octal Transparent Latch

MC74LCX373
Low-Voltage CMOS
Octal Transparent Latch
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX373 is a high performance, non−inverting octal
transparent latch operating from a 2.3 to 3.6 V supply. High
impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A V_I specification of 5.5 V allows
MC74LCX373 inputs to be safely driven from 5 V devices.
The MC74LCX373 contains 8 D−type latches with 3−state outputs.
When the Latch Enable (LE) input is HIGH, data on the Dn inputs
enters the latches. In this condition, 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 transition of LE.
The 3−state standard outputs are controlled by the Output Enable (OE)
input. When OE is LOW, the standard outputs are enabled. When OE
is HIGH, the standard outputs are in the high impedance state, but this
does not interfere with new data entering into the latches.
