MC74VHC1G126

Noninverting 3−State Buffer

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 7.0 V are applied, regardless of the supply voltage. This

allows the MC74VHC1G126 to be used to interface 5.0 V circuits to

3.0 V circuits.
