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 100Ω 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.
