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, jitter-free output signals. In addition, they have a greater noise margin then conventional inverters. The MC74AC14/74ACT14 has hysteresis between the positive-going and negative-going input thresholds (typically 1.0 V) which is determined internally by transistor ratios and is essentially insensitive to temperature and supply voltage variations. • Schmitt Trigger Inputs • Outputs Source/Sink 24 mA • ′ACT14 Has TTL Compatible Inputs HEX INVERTER SCHMITT TRIGGER N SUFFIX CASE 646-06 PLASTIC VCC 14 13 12 11 10 9 8 FUNCTION TABLE 1 2 3 4 5 6 Input Output A O L H H L 7 GND D SUFFIX CASE 751A-03 PLASTIC MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) –0.5 to +7.0 V Vin DC Input Voltage (Referenced to GND) –0.5 to VCC +0.5 V Vout DC Output Voltage (Referenced to GND) –0.5 to VCC +0.5 V Iin DC Input Current, per Pin ±20 mA Iout DC Output Sink/Source Current, per Pin ±50 mA ICC DC VCC or GND Current per Output Pin ±50 mA Tstg Storage Temperature –65 to +150 °C * Maximum Ratings are those values beyond which damage to the device may occur.
