74AC14 · 74ACT14 Hex Inverter with Schmitt Trigger Input
November 1988 Revised December 1999
74AC14 · 74ACT14 Hex Inverter with Schmitt Trigger Input
General Description
The 74AC14 and 74ACT14 contain six inverter gates each with a Schmitt trigger input. They are capable of transforming slowly changing input signals into sharply defined, jitterfree output signals. In addition, they have a greater noise margin than conventional inverters. The 74AC14 and 74ACT14 have hysteresis between the positive-going and negative-going input thresholds (typically 1.0V) which is determined internally by transistor ratios and is essentially insensitive to temperature and supply voltage variations.

Absolute Maximum Ratings(Note 1)
Supply Voltage (VCC) DC Input Diode Current (IIK) VI = -0.5V VI = VCC + 0.5V DC Input Voltage (VI) DC Output Diode Current (IOK) VO = -0.5V VO = VCC + 0.5V DC Output Voltage (VO) DC Output Source or Sink Current (IO) DC VCC or Ground Current per Output Pin (ICC or IGND) Storage Temperature (TSTG) Junction Temperature (TJ) PDIP 140°C ±50 mA -65°C to +150°C ±50 mA -20 mA +20 mA -0.5V to VCC + 0.5V -20 mA +20 mA -0.5V to VCC + 0.5V -0.5V to +7.0V
Recommended Operating Conditions
Supply Voltage (VCC) AC ACT Input Voltage (VI) Output Voltage (VO) Operating Temperature (TA) 2.0V to 6.0V 4.5V to 5.5V 0V to VCC 0V to VCC -40°C to +85°C
Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of FACT circuits outside databook specifications.
