74LCX126 − Low Voltage Quad Buffer with 5V tolerant Inputs and Outputs

The LCX126 contains four independent non-inverting buffers 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.     The 74LCX126 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
