|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| ||||||||||||||||||||||||||||||||| Features PI4IOE5V9673 Remote 16-bit I/O expander for Fm+ I2C-bus with interrupt and reset Description  Operation power supply voltage from 2.3V to 5.5V  16-bit remote I/O pins that default to inputs at power- up  1 MHz I2C-bus interface  Compliant with the I2C-bus Fast and Standard modes  5.5V tolerant I/Os  SDA with 30 mA sink capability for 4000 pF buses  Latched outputs with 25 mA sink capability for directly driving LEDs  Total package sink capability of 400 mA  Active LOW open-drain interrupt output  Low standby current  16 programmable slave addresses using 2 address pins  ESD protection (4KV HBM and 1KV CDM)  Latch-up tested (exceeds 100mA)  Offered in three different packages: TSSOP-24 and TQFN 4x4-24 The PI4IOE5V9673 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus family. The PI4IOE5V9673 provides higher Fast-mode Plus (Fm+) I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM dimming of LEDs, higheI2C-bus drive (30 mA) so that many more devices can be on the bus without the need for bus buffers, high total package sink capacity (400 mA) that supports having all 25 mA LEDs on at the same time and more device addresses (16) are a...
