74LVC14A HEX INVERTERS WITH SCHMITT TRIGGER INPUTS Description Pin Assignments The 74LVC14A provides six independent schmitt trigger inverter buffers. The device is designed for operation with a power supply range of 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment. The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down. The gates perform the positive Boolean function: Y = A Features Wide Supply Voltage Range from 1.65V to 5.5V Outputs sink or source 24mA at V = 3.3V CC CMOS low power consumption Applications IOFF Supports Partial-Power-Down Mode Operation Voltage Level Shifting Inputs or outputs accept up to 5.5V General Purpose Logic Inputs can be driven by 3.3 V or 5.5V allowing for voltage Power Down Signal Isolation translation applications.
