SX1508B Datasheet (Semtech Corporation) - Worlds Lowest Voltage Level Shifting GPIO

SX1508B, Worlds Lowest Voltage Level Shifting GPIO

The SX1508B and SX1509B are complete ultra low voltage General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment.

This family of GPIOs comes in 8-, 16-channel configuration and allows easy serial 2 expansion of I/O through a standard 400kHz I C int

SX1508B 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
