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.
