74LCX540 — Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs December 2013 74LCX540 Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs Features ■ 5V tolerant input and outputs ■ 2.3V–3.6V VCC specifications provided ■ 6.5ns tPD max. (VCC = 3.3V), 10µA ICC max. ■ Power down high impedance inputs and outputs ■ Supports live insertion/withdrawal(1) ■ Implements proprietary noise/ EMI reduction circuitry ■ Latch-up performance exceeds JEDEC 78 conditions ■ ESD performance – Human body model > 2000V – Machine model > 200V ■ Leadless DQFN package Note: 1. To ensure the high impedance state during power up or down, OE should be tied to VCC through a pull-up resistor: the minimum value of the resistor is determined by the current-sourcing capability of the driver. General Description 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 main...
