CAT9532 Datasheet 16-bit Programmable Led Dimmer

Manufacturer: onsemi

Overview: CAT9532 16-bit Programmable LED Dimmer with I2C Interface.

General Description

The CAT9532 is a CMOS device that provides 16−bit parallel input/output port expander optimized for LED dimming control.

The CAT9532 outputs can drive directly 16 LEDs in parallel.

Each individual LED may be turned ON, OFF, or blinking at one of two programmable rates.
