74VHC125 Overview
The VHC125 contains four independent non-inverting buffers with 3-STATE outputs. It is an advanced highspeed CMOS device fabricated with silicon gate CMOS technology and achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply voltage.
