PCA9537 4-bit I2C and SMBus low power I/O port

PCA9537 Description

PCA9537 4-bit I2C-bus and SMBus low power I/O port with interrupt and reset Rev.7 * 8 September 2021 Product data sheet COMPANY PUBLIC .
The PCA9537 is a 10-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C-bu.

PCA9537 Features

* 4-bit I2C-bus GPIO with interrupt and reset
* Operating power supply voltage range of 2.3 V to 5.5 V
* 5 V tolerant I/Os
* Polarity Inversion register
* Active LOW interrupt output
* Active LOW reset input
* Low standby current
* Nois

PCA9537 Applications

* It was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push-buttons, LEDs, fans, etc. The PCA9537 consists of a 4-bit Configuration register (input or output selectio
