Fonctionnalités et applications
The PCA9575PW2,118 is a Part of PCA9575 Series 16-Bit I²C-bus and SMBus with level translating, low voltage GPIO with reset and interrupt. Operating temperature ranges from -40 to 85°C and is available in TSSOP-28 Package.

It is a CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion in low voltage processor and handheld battery powered mobile applications and was developed to enhance the NXP family of I2C-bus I/O expanders.

Features and benefits:

  • Separate supply rails for core logic and each of the two I/O banks provides voltage level shifting
  • 1.1 V to 3.6 V operation with level shifting feature
  • Very low standby current: < 2 uA
  • 16 configurable I/O pins organized as 2 banks that default to inputs at power-up
  • Outputs:
    • Totem pole: 1 mA source and 3 mA sink
    • Independently programmable 100 kΩ pull-up or pull-down for each I/O pin
    • Open-drain active LOW interrupt (1) output pin allows monitoring of logic level change of pins programmed as inputs
  • Inputs:
    • Programmable bus hold provides valid logic level when inputs are not actively driven
    • Programmable Interrupt Mask Control for input pins that do not require an interrupt when their states change or to prevent spurious interrupts default to mask at power-up
    • Polarity Inversion register allows inversion of the polarity of the I/O pins when read
  • 400 kHz I²C-bus serial interface
  • Compliant with I²C-bus Standard-mode (100 kHz)
  • Active LOW reset (1) input pin resets device to power-up default state
  • GPIO All Call address allows programming of more than one device at the same time with the same parameters
  • 16 programmable slave addresses using 4 address pins (28-pin TSSOP only)
  • ESD protection exceeds 6000 V HBM per JESD22-A114, 500 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: TSSOP28, TSSOP24, HWQFN24
