DS36950
Quad Differential Bus Transceiver
General Description
The DS36950 is a low power, space-saving quad EIA-485
differential bus transceiver especially suited for high speed,
parallel, multipoint, computer I/O bus applications. A com-
pact 20-pin surface mount PLCC package provides high
transceiver integration and a very small PC board footprint.
Timing uncertainty across an interface using multiple de-
vices, a typical problem in a parallel interface, is
specified — minimum and maximum propagation delay times
are guaranteed.
Six devices can implement a complete IPI master or slave
interface. Three transceivers in a package are pinned out for
connection to a parallel databus. The fourth transceiver, with
the flexibility provided by its individual enables, can serve as
a control bus transceiver.
