Description
The PCA6408A is an 8-bit general purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface.
Features
- I2C-bus to parallel port expander.
- Operating power supply voltage range of 1.65 V to 5.5 V.
- Allows bidirectional voltage-level translation and GPIO expansion between:.
- 1.8 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P.
- 2.5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P.
- 3.3 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P.
- 5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P.
- Low standby current consumption of 1 A.
- Schmitt-trigger action allows slow.
