DS36954 Datasheet | Texas Instruments

FEATURES - 2 Pinout for SCSI Interface - pact 20-Pin PLCC or SOIC Package - Meets EIA-485 Standard for Multipoint Bus Transmission - Greater than 60 m A Source/Sink Currents - Thermal Shutdown Protection - Glitch-Free Driver Outputs on Power Up and Down DESCRIPTION The DS36954 is a low power, quad EIA-485 differential bus transceiver especially suited for high speed, parallel, multipoint, I/O bus applications. A pact 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 plete 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.
