Schmitt-Trigger Inverter
MC74VHC1G14
The MC74VHC1G14 is a single gate CMOS Schmitt–trigger inverter 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 buffer output which provides high noise immunity and stable output. The
MC74VHC1G14 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the
MC74VHC1G14 to be used to interface 5 V circuits to 3 V circuits.
The MC74VHC1G14 can be used to enhance noise immunity or to square up slowly changing waveforms.
• High Speed: t
• Low Power Dissipation: I
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Pin and Function Compatible with Other Standard Logic Families
• Chip Complexity: FETs = 101; Equivalent Gates = 25

beyond those indicated may adversely affect device reliability . Functional operation under absolute–maximum–rated conditions is
not implied. Functional operation should be restricted to the Recommended Operating Conditions.
