The DS36954 is a low power, quad EIA-485 differential bus transceiver especially suited for high speed, parallel, multipoint, I/O bus applications. A compact 20-pin surface mount PLCC or SOIC package provides high transceiver integration and a very small PC board footprint.

Propagation delay skew between devices is specified to aid in parallel interface designs—limits on maximum and minimum delay times are verified.

Five devices can implement a complete SCSI initiator or target interface. Three transceivers in a package are pinned out for data bus connections. The fourth transceiver, with the flexibility provided by its individual enables, can serve as a control bus transceiver.

  • Pinout for SCSI Interface
  • Compact 20-Pin PLCC or SOIC Package
  • Meets EIA-485 Standard for Multipoint Bus Transmission
  • Greater than 60 mA Source/Sink Currents
  • Thermal Shutdown Protection
  • Glitch-Free Driver Outputs on Power Up and Down
