Buffer/Line Driver 8-CH Inverting 3-ST CMOS 20-Pin TSSOP Rail

The 74LCX540 is a Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs The LCX540 is an octal buffer/line driver designed to be employed as a memory and address driver, clock driver and bus oriented transmitter/receiver. This device is similar in function to the LCX240 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes this device especially useful as an output port for microprocessors, allowing ease of layout and greater PC board density. The LCX540 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX540 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
