Features & Applications

The PCA9557D,118 is a part of PCA9557 Series with silicon CMOS circuit which provides parallel input/output expansion for SMBus and I2C-bus applications. The PCA9557 consists of an 8-bit input port register, 8-bit output port register, and an I2C-bus/SMBus interface. It has low current consumption and a high-impedance open-drain output pin, IO0. Temprature ranges from –40 to +85 °C and its AVailable in a SOIC-16 Package

Features:

  • Lower voltage, higher performance migration path for the PCA9556
  • 8 general purpose input/output expander/collector
  • Input/output configuration register
  • Active HIGH polarity inversion register
  • I2C-bus and SMBus interface logic
  • Internal power-on reset
  • Noise filter on SCL/SDA inputs
  • Active LOW reset input
  • 3 address pins allowing up to 8 devices on the I2C-bus/SMBus
  • High-impedance open-drain on IO0
  • No glitch on power-up
  • Power-up with all channels configured as inputs
  • Low standby current
  • 5 V tolerant inputs/outputs
  • ESD protection exceeds 2000 V HBM per JESD22-A114, 150 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
  • Three packages offered: SO16, TSSOP16, HVQFN16
