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 VI 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.
