Product details

Description

The CAT9554 and CAT9554A are CMOS devices that provide 8 bit parallel input/output port expansion for I2C and SMBus compatible applications. compatible serial interface.

Features

an active low interrupt output which indicates to the system master that an input state has changed. The device’s extended addressing capability allows up to 8 devices to share the same bus. The CAT9554A is identical to the CAT9554 except the fixed part of the I2C slave address is different. This allows up to 16 of devices (eight CAT9554 and eight CAT9554A) to be connected on the same bus. Features.
400 kHz I2C Bus Compatible (Note 1).
2.3 V to 5.5 V Operation.
Low Sta.
