MC74AC14, MC74ACT14 Hex Inverter Schmitt Trigger The MC74AC14/74ACT14 contains six logic inverters which accept standard CMOS Input signals (TTL levels for MC74ACT14) and provide standard CMOS output levels. They are capable of transforming slowly changing input signals into sharply defined, MC74AC14, MC74ACT14 RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Typ Max Unit AC 2.0 5.0 6.0 V Supply Voltage V CC ACT 4.5 5.0 5.5 V , V DC Input Voltage, Output Voltage (Ref. to GND) 0 V V in out CC V 3.0 V 150 CC Input Rise and Fall Time (Note 1) t , t V 4.5 V 40 ns/V CC r f AC Devices except Schmitt Inputs V 5.5 V 25 CC V 4.5 V 10 Input Rise and Fall Time (Note 2) CC t , t ns/V r f ACT Devices except Schmitt Inputs V 5.5 V 8.0 CC T Junction Temperature (PDIP) 140 C J T Operating Ambient Temperature Range 40 25 85 C A I Output Current High 24 mA OH I Output Current Low 24 mA OL 1.
