General Description
The PCA9674/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).
Key Features
- I2C-bus to parallel port expander.
- 1 MHz I2C-bus interface (Fast-mode Plus I2C-bus).
- SDA with 30 mA sink capability for 4000 pF buses.
- Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to VDD with 100 A current source.
- 8-bit remote I/O pins that default to inputs at power-up.
- Latched outputs with 25 mA sink capability for directly driving LEDs.
- Total package sink capability of 200 mA NXP Semiconductors PCA9674; PCA9674A Remote 8-bit I/O.
