Low-Voltage CMOS 16-Bit Transparent Latch
With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

The MC74LCX16373 is a high performance, non−inverting 16−bit transparent latch operating from a 2.3 V to 3.6 V 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 5.5 V allows MC74LCX16373 inputs to be safely driven from 5.0 V devices.
