74LCX244  
Low Voltage Buffer/Line Driver  
with 5V Tolerant Inputs and Outputs  
General Description  
Features  
■ 5V tolerant inputs and outputs  
The LCX244 contains eight non-inverting buffers with  
3-STATE outputs. The device may be employed as a mem-  
ory address driver, clock driver and bus-oriented transmit-  
ter/receiver. The LCX244 is designed for low voltage (2.5V  
or 3.3V) VCC applications with capability of interfacing to a  
■ 2.3V to 3.6V VCC specifications provided  
■ 6.5 ns tPD max (VCC 3.3V), 10 A ICC max  
■ Power down high impedance inputs and outputs  
■ Supports live insertion/withdrawal (Note 1)  
5V signal environment.  
The LCX244 is fabricated with an advanced CMOS tech-  
nology to achieve high speed operation while maintaining  
CMOS low power dissipation.  
■
24 mA output drive (VCC 3.0V)  
■ Implements patented noise/EMI reduction circuitry  
■ Latch-up performance exceeds 500 mA  
■ ESD performance:  
Human body model 2000V  
Machine model 200V  
■ Leadless DQFN Pb-Free package  
Note 1: To ensure the high-impedance state during power up or down, OE  
should be tied to V  
through a pull-up resistor: the minimum value or the  
CC  
resistor is determined by the current-sourcing capability of the driver.
