MC74LCX573/D
MC74LCX573
Low-Voltage CMOS
Octal Transparent Latch
Flow Through Pinout
With 5 V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
The MC74LCX573 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
MC74LCX573 inputs to be safely driven from 5.0 V 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.
