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.

FEATURES

Eight Channels of Programmable I/O with Open-Drain Outputs
On-Resistance of PIO Pulldown Transistor 100â„¦(max); Off-Resistance 10Mâ„¦(typ)
Individual Activity Latches Capture Asynchronous State Changes at PIO Inputs for Interrogation by the Bus Master
Data-Strobe Output to Synchronize PIO Logic States to External Read/Write Circuitry
Built-in Multidrop Controller Ensures Compatibility with Other Dallas Semiconductor 1-WireÂ® Net Products
Supports 1-Wire Conditional Search Command with Response Controlled by Programmable PIO Conditions
Unique Factory-Lasered 64-Bit Registration Number Ensures Error-Free Device Selection and Absolute Part Identity
Communicates to Host with a Single Digital Signal at 15.3kbps or 100kbps using 1-Wire Protocol
Operating Range: 2.8V to 5.25V, -40Â°C to +85Â°C
