Features
  • Pinout for IPI interface
  • Compact 20-pin PLCC package
  • Meets EIA-485 standard for multipoint bus transmission
  • Greater than 60 mA source/sink
  • Thermal Shutdown Protection
  • Description

    The DS36950 is a low power, space-saving quad EIA-485 differential bus transceiver especially suited for high speed, parallel, multipoint, computer I/O bus applications. A compact 20-pin surface mount PLCC package provides high transceiver integration and a very small PC board footprint.

    Timing uncertainty across an interface using multiple devices, a typical problem in a parallel interface, is specified-minimum and maximum propagation delay times are guaranteed.

    Six devices 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.
