AEC-Q100 compliant interface timing solutions

A range of flip-flop circuits that meets the requirements of the automotive electronics council's AEC-Q100 and recommended for automotive applications.

By only allowing the output to change on an edge transition, flip flops provide a robust interface between asynchronous and synchronous system.

Descriptive summary

Flip-flops are basic storage elements in digital electronics. They transfer input data to the outputs on an edge transition of their clock input. NXP offers a comprehensive range of D-type and JK-type flip-flops configured as either positive or negative edge triggered for design flexibility.

Synchronizing asynchronous signals to a specific reference, adding delay to a signal, frequency division, counting of pulses and shifting of data are some common uses of flip-flops. In automotive electronics, flip-flops can be used for timing synchroniztion in virtual dash boards, video display systems, body control and central gateway systems adjusting seat position, controlling power windows, interior abd exterior lights.

Flip-flops are available in standard SO, TSSOP, PicoGate and innovative leadless MicroPak and DQFN package for PCB space saving. NXP's automotive flip-flops are fully specified from -40 °C to 125 °C, and are qualified per AEC-Q100 grade 1.
