74LCX541
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)
■ ±24 mA output drive (VCC = 3.0V)
■ 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 LCX541 is an octal buffer/line driver designed to be
employed as memory and address drivers, clock drivers
and bus oriented transmitter/receivers. The LCX541 is a
non inverting option of the LCX540.
This device is similar in function to the LCX244 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 LCX541 is designed for low voltage applications
with capability of interfacing to a 5V signal environment.
The LCX541 is fabricated with an advanced CMOS
technology to achieve high speed operation while
maintaining CMOS low power dissipation.
