DESCRIPTION

The DS2408 is an 8-channel, programmable I/O 1-Wire chip. PIO outputs are configured as open-drain and provide an on resistance of 100
max. A robust PIO channel-access communication protocol ensures that PIO output-setting changes occur error-free. A data-valid strobe output can be used to latch PIO logic states into external circuitry such as a D/A converter (DAC) or microcontroller data bus.
