74VHC14; 74VHCT14
Applications
Schmitt triggers are able to transform the slowly changing input signals into sharply defined jitter free output signals. These devices are useful in systems with noisy input signals that have large slew rates and can cause the oscillations or undefined logic levels at outputs. Integration of Schmitt triggers inputs saves the cost and space of using standalone Schmitt triggers on boards.
Schmitt trigger products are available in standard SO, TSSOP, PicoGate and innovative leadless MicroPak and DQFN packages for PCB space saving.
Features and benefits
- Prevents multiple switching when driven by slow edges
- Cleans up the noisy signals
- Reshapes the signals in complex layouts
- Suitable for mixed 3.3 V and 5.0 V applications
- Wide voltage supply range
- Input hysteresis
- Open drain output options
- CMOS and TTL variants
- Overvoltage tolerant input options
Applications
- Sine wave to square wave conversion
- Interface between analog and digital environments
- Increase noise immunity in design
- Relaxation oscillators
