74LVC540A

Low-Voltage CMOS

Octal Buffer

Flow Through Pinout

With 5 V−Tolerant Inputs and Outputs

(3−State, Inverting)

The 74LVC540A is a high performance, inverting octal buffer

operating from a 1.2 to 3.6 V 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 5.5 V allows

74LVC540A inputs to be safely driven from 5 V devices. The

74LVC540A is suitable for memory address driving and all TTL level

bus oriented transceiver applications.

Current drive capability is 24 mA at the outputs. The Output Enable

(OE1, OE2) inputs, when HIGH, disables the outputs by placing them

in a HIGH Z condition.

Features

• Designed for 1.2 to 3.6 V VCC Operation

• 5 V Tolerant − Interface Capability With 5 V TTL Logic

• Supports Live Insertion and Withdrawal

• IOFF Specification Guarantees High Impedance When VCC = 0 V

• 24 mA Output Sink and Source Capability

• Near Zero Static Supply Current in All Three Logic States (10 mA)

Substantially Reduces System Power Requirements

• Latchup Performance Exceeds 250 mA

• ESD Performance:

♦ Human Body Model > 2000 V

♦ Machine Model > 200 V

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS

Compliant
