Logic device/transceiver/encoder

The MC74VHC1G125 is an advanced high speed CMOS non-inverting 3-state buffer fabricated on a silicon gate CMOS process. It achieves high-speed operation similar to an equivalent bipolar Schottky TTL while maintaining CMOS low power consumption. The internal circuitry consists of three stages, including a buffered 3-state output that provides high noise immunity and stable output. The MC74VHC1G125 input structure provides protection when voltages up to 5.5V are applied regardless of the supply voltage. This allows the MC74VHC1G125 to be used as an interface to 5V to 3V circuits.
