onsemi LED Drivers NLSF595DTR2

The NLSF595DTR2 is a serial (SPI) tri-color LED driver designed for efficient control of LED outputs. It features an advanced CMOS shift register with open-drain outputs, capable of sinking over 12 mA per output. The device operates within a voltage range of 2.0 to 5.5 volts, with output levels independent of the supply voltage, allowing for up to 7.0 volts on the outputs without damage. This LED driver supports a high-speed clocking frequency of over 25 MHz and provides eight bits of parallel output, enabling the control of two tri-color LEDs per device. It includes double-buffered outputs, allowing data to be loaded without affecting the output state. The NLSF595DTR2 is compatible with standard CMOS logic levels and requires only one dedicated pin for operation, which helps free up I/O resources on the microcontroller. The device is available in TSSOP-16 and QFN-16 packages, with low leakage current of 2.0 ¬µA maximum at 25¬8C, and robust ESD performance exceeding 2000 V for the human body model. It is functionally similar to the popular 74VHC595, making it a reliable choice for applications requiring efficient LED control.
