2 1Y output Output of first inverter (Y = NOT A); drives up to ±50mA with VOH ≥ 2.2V at IOH = -12mA and VOL ≤ 0.55V at IOL = 24mA at VCC = 3V.
3 2A input Schmitt-trigger input to second inverter; accepts 0V to 5.5V with hysteresis thresholds VT+ = 0.9V to 1.1V and VT- = 0.6V to 0.8V at VCC = 3V.
4 2Y output Output of second inverter (Y = NOT A); drives up to ±50mA with VOH ≥ 2.2V at IOH = -12mA and VOL ≤ 0.55V at IOL = 24mA at VCC = 3V.
5 3A input Schmitt-trigger input to third inverter; accepts 0V to 5.5V with hysteresis thresholds VT+ = 0.9V to 1.1V and VT- = 0.6V to 0.8V at VCC = 3V.
6 3Y output Output of third inverter (Y = NOT A); drives up to ±50mA with VOH ≥ 2.2V at IOH = -12mA and VOL ≤ 0.55V at IOL = 24mA at VCC = 3V.
7 GND power_in Ground pin; 0V reference potential for the device.
8 4Y output Output of fourth inverter (Y = NOT A); drives up to ±50mA with VOH ≥ 2.2V at IOH = -12mA and VOL ≤ 0.55V at IOL = 24mA at VCC = 3V.
9 4A input Schmitt-trigger input to fourth inverter; accepts 0V to 5.5V with hysteresis thresholds VT+ = 0.9V to 1.1V and VT- = 0.6V to 0.8V at VCC = 3V.
