MAX7315AEE+T

I/O Expander 8 I²C, SMBus 400 kHz 16-QSOP

Inquiry Add To Bom

MAX7315AEE+T General Description

The MAX7315 I²C-/SMBus™-compatible serial interfaced peripheral provides microprocessors with 8 I/O ports. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA at 5.5V, or a logic input with transition detection. A ninth port can be used for transition detection interrupt or as a general-purpose output. The outputs are capable of directly driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V.
