A compact 20-pin surface mount PLCC package provides high transceiver integration and a very small PC board footprint.
Timing uncertainty across an interface DS36950 using multiple devices, a typical problem in a parallel interface, is specified-minimum and maximum propagation delay times are guaranteed.
Six devices DS36950 can implement a complete IPI master or slave interface. Three transceivers in a package are pinned out for connection to a parallel databus. The fourth transceiver, with the flexibility provided by its individual enables, can serve as a control bus transceiver.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
