74AHC14 HEX INVERTERS WITH SCHMITT TRIGGER INPUTS Description Pin Assignments The 74AHC14 provides provides six independent Schmitt trigger input ( Top View ) inverters with standard push-pull outputs. The device is designed for operation with a power supply range of 2.0V to 5.5V. The inputs are 1 14 Vcc 1A tolerant to 5.5V allowing this device to be used in a mixed voltage 2 13 1Y 6A environment. 3 12 2A 6Y The gates perform the Boolean function: 4 11 2Y 5A Y = A 5 10 3A 5Y Features 6 9 3Y 4A Wide Supply Voltage Range from 2.0V to 5.5 V 7 8 GND 4Y Outputs Sink or Source 8mA at V = 4.5V CC CMOS Low Power Consumption SO-14 / TSSOP-14 Schmitt Trigger Action at All Inputs Typical hysteresis of 1V allows for transformation of slow changing input signals to sharply defined, fast transition output Applications signals. Inputs can be driven by 3.3V or 5.5V allowing for voltage General Purpose Logic translation applications.
