DESCRIPTION

The PCA9556 is a silicon CMOS circuit which provides parallel input/output expansion for SMBus applications.

FEATURES

• SMBus compliance with fixed 3.3V voltage levels

• Operating power supply voltage range of 3.0 V – 5.5 V

• Active high polarity inverter register

• Each I/O is configurable as an input or output

• Active low reset pin

• Low leakage current on power-down

• Noise filter on SCL/SDA inputs

• No glitch on power-up

• Internal power-on reset

• 8 I/O pins which default to 8 inputs

• High impedance open drain on I/O0

• 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 JESDEC Standard JESD78 which

exceeds 100 mA
