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 100ꢀ 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.  
DS2408 operation is controlled over the single-conductor 1-Wire bus. Device communication follows the  
standard Dallas Semiconductor 1-Wire protocol. Each DS2408 has its own unalterable and unique 64-bit  
ROM registration number that is factory lasered into the chip. The registration number guarantees unique  
identification and is used to address the device in a multidrop 1-Wire net environment. Multiple DS2408  
devices can reside on a common 1-Wire bus and can operate independently of each other. The DS2408  
also supports 1-Wire conditional search capability based on PIO conditions or power-on-reset activity;  
the conditions to cause participation in the conditional search are programmable. The DS2408 has an  
optional VCC supply connection. When an external supply is absent, device power is supplied parasitically  
from the 1-Wire bus. When an external supply is present, PIO states are maintained in the absence of the  
1-Wire bus power source. The RSTZ signal is configurable to serve as either a hard-wired reset for the  
PIO output or as a strobe for external circuitry to indicate that a PIO write or PIO read has completed.  
1-Wire is a registered trademark of Dallas Semiconductor.
