Product Preview

Buffer

The MC74VHC1G50 is an advanced high speed CMOS 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

output which provides high noise immunity and stable output.

The MC74VHC1G50 input structure provides protection when

voltages up to 7V are applied, regardless of the supply voltage. This

allows the MC74VHC1G50 to be used to interface 5V circuits to 3V

circuits.
