PCF8574
Description
The PCF8574/74A 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 2.5 V to 6 V with non-overvoltage tolerant I/O held to VDD with 100 A current source
- 8-bit remote I/O pins that default to inputs at power-up
- Latched outputs directly drive LEDs
- Total package sink capability of 80 mA
- Active LOW open-drain interrupt output
- Eight programmable slave addresses using three address pins
- Low standby current (2.5 A typical)
- 40 C to +85 C operation
- Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA
