www.ti.com SNLS077C – JULY 1998 – REVISED APRIL 2013 DS36954 Quad Differential Bus Transceiver
Check for Samples: DS36954 FEATURES 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. 1 2 Pinout for SCSI Interface

Down 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. Connection Diagram Logic Diagram See Package Number FN (S-PQCC-J20) See Package Number DW (R-PDSO-G20) 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of …
