GENERAL DESCRIPTION

The DS2413 is a dual-channel programmable I/O 1-

Wire

drain and provide up to 20mA continuous sink

capability and off-state operating voltage up to 28V.

Control and sensing of the PIO pins is performed with

a dedicated device-level command protocol. To

provide a high level of fault tolerance in the end

application, the 1-Wire IO and PIO pins are all

capable of withstanding continuous application of

voltages up to 28V max. Communication and

operation of the DS2413 is performed with the single

contact Maxim/Dallas 1-Wire serial interface.
