MC74VHC1GT14DFT1G

The MC74VHC1G14 / MC74VHC1GT14 is a single inverter with Schmitt-trigger input in a micro package. The MC74VHC1G14 features CMOS-level input thresholds, while the MC74VHC1GT14 features TTL-level input thresholds. The internal circuit consists of three stages, including a buffered output stage that provides high noise immunity and stable output. The input structure provides protection when voltages up to 5.5V are applied, independent of the supply voltage. This allows the device to be used for interfacing between 5V and 3V circuits. The output structure also provides protection when VCC = 0V and when the output voltage exceeds VCC. These input and output structures help prevent device damage caused by supply voltage and input/output voltage mismatches, battery backup, hot-plugging, and similar conditions.

Key features

• CPD is defined as the value of the IC's internal equivalent capacitance calculated from the operating current consumption with no load. Average operating current: ICC(OPR) τ = CPD × VCC × fin + ICC. CPD is used to determine the no-load dynamic power dissipation; PD = CPD × VCC² × fin + ICC × VCC (derivative)
