Overview

The MC74LCX16373DT is a high performance, non-inverting 16-bit transparent latch operating from a 2.3 to 3.6V supply. The device is byte controlled. Each byte has separate Output Enable and Latch Enable inputs. These control pins can be tied together for full 16-bit operation. 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 MC74LCX16373DT inputs to be safely driven from 5V devices.The MC74LCX16373DT contains 16 D-type latches with 3-state 5V-tolerant outputs. When the Latch Enable (LEn) inputs are 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 outputs are controlled by the Output Enable(OEnbar) inputs. When OEbar is LOW, the outputs are enabled. When OEbar is HIGH, the standard outputs are in the high impedance state, but this does not interfere with new data entering into the latches.
