Multiplexers & Switches

NXP’s I2C –bus enablers for complex bus topologies

NXP’s I/O expander (GPIO) drives LED and monitors switches without using any microprocessor pins.

More Information

LCD Display Drivers

LCD Segment, Character and Graphic Drivers

I2C -bus multiplexers and switches connect an upstream I2C -bus to any combination of downstream I2C busses.

More Information

Real Time Clocks (RTC)

Precision time keeping

LCD display drivers for a variety of applications. AEC-Q100 qualified versions available

More Information

RTCs to suit applications needing accurate time keeping: ultra-low power, high-temperature tolerant, temperature compensated, and high-accuracy

More Information

Bridge ICs allow designers to connect together devices that use different serial buses. Interface between standard parallel bus and the serial I2C –bus.

More Information

LED Controllers

Connect LEDs directly and control their brightness & color

I2C-bus functions for any system. Serial EEProms to store configuration data and DIP switches for replacement of mechanical switches

More Information

Temperature
Sensors

Accurate temperature readings in any environment

LED controllers/drivers for blinking, dimming, and color mixing LEDs. Using I2C LED controllers frees the microprocessor for other purposes.

More Information
