74LCX244
Low Voltage Buffer/Line Driver with 5V Tolerant
Inputs and Outputs
Features
General Description
■ 5V tolerant inputs and outputs
The LCX244 contains eight non-inverting buffers with
3-STATE outputs. The device may be employed as a
memory address driver, clock driver and bus-oriented
transmitter/receiver. The LCX244 is designed for low
voltage (2.5V or 3.3V) VCC applications with capability of
interfacing to a 5V signal environment.
■ 2.3V to 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)
■ ±24mA output drive (VCC = 3.0V)
■ Implements proprietary noise/EMI reduction circuitry
■ Latch-up performance exceeds 500mA
The LCX244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
■ 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 or the resistor is
determined by the current-sourcing capability of the
driver.
