Low-Voltage CMOS Octal Transparent Latch
With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting)
MC74LCX373
The MC74LCX373 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 MC74LCX373 inputs to be safely driven from 5V 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.
