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 VI 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.
