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, 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. http://onsemi.com PDIP–14 N SUFFIX CASE 646 14 1 14 1 SO–14 D SUFFIX CASE 751A Schmitt Trigger Inputs Outputs Source/Sink 24 mA ′ACT14 Has TTL Compatible Inputs VCC 14 13 12 11 10 9 8 14 1 TSSOP–14 DT SUFFIX CASE 948G 14 1 EIAJ–14 M SUFFIX CASE 965 1 2 3 4 5 6 7 GND ORDERING INFORMATION Device MC74AC14N Package PDIP–14 PDIP–14 SOIC–14 SOIC–14 SOIC–14 SOIC–14 TSSOP–14 Shipping 25 Units/Rail 25 Units/Rail 55 Units/Rail 2500 Tape & Reel 55 Units/Rail 2500 Tape & Reel 96 Units/Rail Figure 1.
