SEMICONDUCTOR TECHNICAL DATA

The MC74LCX573 is a high performance, non–inverting octal

transparent latch operating from a 2.7 to 3.6V supply. High impedance

TTL compatible inputs significantly reduce current loading to input drivers

while TTL compatible outputs offer improved switching noise

performance. A V specification of 5.5V allows MC74LCX573 inputs to be

safely driven from 5V devices.

The MC74LCX573 contains 8 D–type latches with 3–state standard

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. The LCX573 flow

through design facilitates easy PC board layout.
