PCA8574A
Description
The PCA8574/74A 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
- 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
- Active LOW open-drain interrupt output
- Eight programmable slave addresses using three address pins
- Low standby current (4.5 A typical)
- 40 C to +85 C operation NXP Semiconductors PCA8574; PCA8574A Remote 8-bit I/O expander for I2C-bus with interrupt
- ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
