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 abd 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 board.
Schmitt trigger buffers can be used to interface sensors, used in tachometers, engine temperature and oil pressure with embedded processors in automotive applications; as well as in signal conditioning, relaxation oscillators, astable and monostable multivibrators and clock drivers in electronic control and automotive lighting systems.
Schmitt triggers products are available in standard SO, TSSOP, PicoGate and innovative leadless MicroPak and DQFN packages for PCB space saving. NXP's automotive Schmitt trigger products are fully specified from -40 °C to 125 °C, and are qualified per AEC-Q100 grade 1.
