MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low-Voltage CMOS Octal Buffer Flow Through Pinout With 5V-Tolerant Inputs and Outputs (3-State, Inverting) The MC74LCX540 is a high performance, inverting octal buffer operating from a 2.7 to 3.6V supply. This device is similar in function to the MC74LCX240, while providing flow through architecture. 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 MC74LCX540 inputs to be safely driven from 5V devices. The MC74LCX540 is suitable for memory address driving and all TTL level bus oriented transceiver applications. Current drive capability is 24mA at the outputs. The Output Enable (OE1, OE2) inputs, when HIGH, disables the outputs by placing them in a HIGH Z condition. 20 MC74LCX540 LOW–VOLTAGE CMOS OCTAL BUFFER DW SUFFIX PLASTIC SOIC CASE 751D–04 1 Designed for 2.7 to 3.6V VCC Operation 5V Tolerant — Interface Capability With 5V TTL Logic Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0V LVTTL Compatible 20 1 M SUFFIX PLASTIC SOIC EIAJ CASE 967–01 LVCMOS Compatible 24mA Balanced Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10A) Substantially Reduces System Power Requirements Latchup Performance Exceeds 500mA 20 1 SD SUFFIX PLASTIC SSOP CASE 940C–03 ESD Performance: Human Body Mo……
