16-bit I2C-bus and SMBus I/O port with interrupt - # of Addresses: 8 ; I2C-bus: 400 kHz; Interrupt: 0-1 ; Max Sink Current per bit: 25 mA; Max Sink Current, per package: 200 mA; Number of bits: 16 ; Operating temperature: -40~85 Cel; Operating voltage: 2.3~5.5 VDC; Source Current per bit: 10 mA; Weak Pull-Up Current Source: yes; Package: SOT340-1 (SSOP24); Container: Reel Pack, SMD, 13"
The PCA9555DB,118 can support I2C bus frequencies up to 400 kHz.
The PCA9555DB,118 has 16 GPIO pins that can be controlled independently.
Each GPIO pin can source or sink up to 25 mA of current.
Yes, the PCA9555DB,118 can be used as a level translator between different voltage domains, allowing for voltage translation between 1.8 V, 2.5 V, 3.3 V, and 5 V.
The PCA9555DB,118 has an interrupt output that can be used to signal to the microcontroller when a GPIO pin changes state. The interrupt output can be configured to trigger on rising, falling, or both edges.
