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), 10A ICC max.
■ Power down high impedance inputs and outputs
■ Supports live insertion/withdrawal(1)
■
■ 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 micropro-
cessors, 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 dissipa-
tion.
