General description

The PCA9536 is an 8-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and 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 PCA9536 consists of a 4-bit Configuration register (input or output selection), 4-bit Input Port register, 4-bit Output Port register and a 4-bit Polarity Inversion register (active HIGH or active LOW operation). The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input Port or Output Port register. The polarity of the read register can be inverted with the Polarity Inversion register. All registers can be read by the system master.

The power-on reset sets the registers to their default values and initializes the device state machine.

The I2C-bus address is fixed and allows only one device on the same I2C-bus/SMBus.

Features

  • 4-bit I2C-bus GPIO
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5 V tolerant I/Os
  • Polarity Inversion register
  • Low standby current
  • Noise filter on SCL/SDA inputs
  • No glitch on power-up
  • Internal power-on reset
  • 4 I/O pins which default to 4 inputs with 100 KOhm internal pull-up resistor
  • 0 Hz to 400 kHz clock frequency
  • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
  • Packages offered: SO8, TSSOP8 (MSOP8), HVSON8
