With a low standby mode current supply of 1µA maximum, the CAT9534 offers a simple and cost-effective solution to add I/Os for functions such as LED indicators, control buttons, fans and sensors, while reducing power consumption in a broad range of end products, including white goods, digital cameras, cell phones, PDAs, routers, hubs and servers.
The CAT9534 consists of eight ports, which power up as inputs and each port can be configured as an input or output by writing to a register. An internal power-on reset eliminates glitches on power-up. Each I/O port is 5V input tolerant, with a high current I/O drive sink of up to 25mA and an I/O source of up to 10mA, maximum. Additionally, each I/O port is compatible with logic thresholds of 2.5V, 3.3V and 5V.

- 400kHz I2C bus compatible
- 2.3V to 5.5V operation
- 8 I/O pins that default to inputs at power-up
- Industrial Operating Temperature: -40°C to +85°C
- Packaging: 16-pin SOIC, TSSOP and 16-pad 4x4 TQFN packages
