74LCX125 Low Voltage Quad Buffer with 5V Tolerant Inputs and Outputs
March 1995
Revised April 1999
74LCX125
Low Voltage Quad Buffer
with 5V Tolerant Inputs and Outputs
General Description
The LCX125 contains four independent non-inverting buff-
ers with 3-STATE outputs. The inputs tolerate voltages up
to 7V allowing the interface of 5V systems to 3V systems.
The 74LCX125 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
