74LCX126  
Low Voltage Quad Buffer  
with 5V Tolerant Inputs and Outputs  
General Description  
Features  
5V tolerant inputs and outputs  
The LCX126 contains four independent non-inverting buff-  
ers with 3-STATE outputs. Each output is disabled when  
the associated output-enable (OE) input is LOW. The  
inputs tolerate voltages up to 7V allowing the interface of  
5V systems to 3V systems.  
2.3V–3.6V VCC specifications provided  
5.5 ns tPD max (VCC = 3.3V), 10 µA ICC max  
Power down high impedance inputs and outputs  
Supports live insertion/withdrawal (Note 1)  
±24 mA output drive (VCC = 3.0V)  
The 74LCX126 is fabricated with an advanced CMOS tech-  
nology to achieve high speed operation while maintaining  
CMOS low power dissipation.  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds 500 mA  
ESD performance:  
Human body model > 2000V  
Machine model > 100V  
Note 1: To ensure the high-impedance state during power up or down, OE  
should be tied to GND through a pull-up resistor: the minimum value or the  
resistor is determined by the current-sourcing capability of the driver.
