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.
The MC74VHC1G50 is an advanced high‑speed CMOS buffer that provides a buffered output for high noise immunity and stable logic levels. It features input protection for voltages up to 7 V, allowing 5 V circuits to interface with 3 V circuits, and offers low power dissipation.
