IS32FL3726A Datasheet | Lumissil

DESCRIPTION The IS32FL3726A is a serial shift-register-plus latch-type LED driver operating from a 3V to 5V supply. It is prised of 16 constant-current open drain sinks designed for driving mon anode LEDs. The output current value can be set from 5m A to 60m A by using an external resistor. As a result, all outputs will have virtually the same current levels. This driver uses a high-speed 4-wire serial interface of up to 30MHz to drive 16 constant current outputs, a 16-bit shift register, a 16-bit latch and a 16-bit AND-gate circuit. Serial input data appears at the --------------- output OUTn channels after 16 clock cycles. Driving the Latch pin will load the 16-bit of shift-register data into the 16-bit output latch to drive the LEDs ON or OFF. The Enable pin can be used as a PWM input to adjust the LED brightness. The IS32FL3726A operates from a 3V to 5.5V supply, and is specified over the -40°C to +125°C temperature range.
