Product description: PCF8574N - microcontroller IO expander board
The system allows to increase the number of IOs (up to 8) of a microcontroller (e.g. Arduino module). Communicates with the central unit via the I2C bus (TWI).
Note
System has a different address bus, depending on version:
- PCF857 0 | 1 | 0 | 0 | A2 | A1 | A0
- PCF8574A 0 | 1 | 1 | 1 | A2 | A1 | A0
Details indocumentation- section 7.1
- PCF8574N/P 0 | 1 | 0 | 0 | A2 | A1 | A0
Details inthe documentationsection 8.3.3
IOs A2 | A1 | A0 can't stay unconnected.
Technical characteristics of expander IOs- Power supply: from 2.5 V to 6 V
- Quiescent current: 100 µa (10 µa in low power mode)
- Communication: I2C (TWI)
- Number of contacts: 8
- Case: DIP-16
Details inthe documentation.
