PCAL9554BPWJ Description

Short technical summary and product information.

The PCAL9554BPWJ from NXP Semiconductors is a low-voltage, 8-bit General Purpose Input/Output (GPIO) expander. It is designed for I2C-bus and SMBus applications, offering interrupt and weak pull-up features. This device supports a wide VDD range from 1.65 V to 5.5 V, enabling compatibility with next-generation microprocessors and microcontrollers.

 

The PCAL9554BPWJ includes Agile I/O features such as programmable output drive strength, latchable inputs, programmable pull-up/pull-down resistors, and maskable interrupts. It has an open-drain interrupt output that signals changes in input states to the system master. The device can drive LEDs directly with its 25 mA sink capability.

 

Packaged in a 16-TSSOP, the PCAL9554BPWJ is suitable for surface mount applications. Its clock frequency is rated at 400 kHz, and it operates within a temperature range of -40°C to 85°C. The device provides 8 I/O pins and supports both open-drain and push-pull output types.
