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

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.
