The MC74VHC1G126 is an advanced high speed CMOS noninverting 3−state buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
The internal circuit is composed of three stages, including a buffered 3−state output which provides high noise immunity and stable output.
The MC74VHC1G126 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHC1G126 to be used to interface 5 V circuits to 3 V circuits.
