 
74VHC14; 74VHCT14
Hex inverting Schmitt trigger
The 74VHC14; 74VHCT14 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A.
The 74VHC14; 74VHCT14 provide six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
Features and benefits
- Balanced propagation delays 
- All inputs have Schmitt-trigger action 
- Inputs accept voltages higher than VCC 
- Input levels: - The 74VHC14 operates with CMOS input level 
- The 74VHCT14 operates with TTL input level 
 
- ESD protection: - HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V 
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V 
 
- Multiple package options 
- Specified from -40 °C to +85 °C and from -40 °C to +125 °C
