The 74HC14D is a hex inverting schmitt trigger. The 74HC14D is a high-speed Si-gate CMOS device and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC14D provides six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
 
74HC14D absolute maximum ratings: (1)VCC supply voltage: -0.5 +7 V; (2)IIK input diode current VI < -0.5 V or VI > VCC + 0.5 V: ±20 mA; (3)IOK output diode current VO < -0.5 V or VO > VCC + 0.5 V: ±20 mA; (4)IO output source or sink current: -0.5 V < VO < VCC + 0.5 V – ±25 mA; (5)ICC; IGND VCC or GND current: – 50 mA; (6)Tstg storage temperature: -65 +150℃.
 
74HC14D features: (1)Complies with JEDEC standard no. 7A; (2)ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V; MM EIA/JESD22-A115-A exceeds 200 V; (3)Specified from -40 to +85℃ and -40 to +125℃.
