MC74LCX543 Datasheet (Motorola) - LOW-VOLTAGE CMOS OCTAL LATCHING TRANSCEIVER

MC74LCX543, LOW-VOLTAGE CMOS OCTAL LATCHING TRANSCEIVER

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Low-Voltage CMOS Octal Latching Transceiver With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting) MC74LCX543 The MC74LCX543 is a high performance, non inverting octal latching transceiver 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
