Features

* 1.2V to 3.6V Low Operating Voltage with Dual Independent I/O Rails (VCC1, VCC2) Enable Direct Level Shifting Between I/O Banks and Host Controller 5.5V Tolerant I/Os, Up to 15mA Output Sink on All I/Os (No Total Sink Current Limit) Integrated LED Driver for Enhanced Lighting Intensity Cont

Applications

* The SX1508B and SX1509B have the ability to generate mask-programmable interrupts based on a falling/rising edge of any of its GPIO lines. A dedicated pin (NINT) indicates to a host controller that a state change occurred on one or more of the lines. Each GPIO is programmable via a bank of 8-bit c
