Overview
The MC74VHC1GT14 is a single Schmitt-Trigger Inverter produced by onsemi. This component is available in various tiny footprint packages, including SC−88A, TSOP−5, SC−74A, SOT−953, and UDFN6. The MC74VHC1GT14 features TTL-level input thresholds, making it suitable for a wide range of applications requiring high noise immunity and stable output.
The internal circuit of the MC74VHC1GT14 consists of three stages, including a buffered output. This design provides high noise immunity and stable output, even when voltages up to 5.5 V are applied, regardless of the supply voltage. This makes the device ideal for interfacing 5 V circuits to 3 V circuits.
