DS36954
Quad Differential Bus Transceiver
General Description
The DS36954 is a low power, quad EIA-485 differential bus
transceiver especially suited for high speed, parallel, multi-
point, I/O bus applications. A compact 20-pin surface mount
PLCC or SOIC package provides high transceiver integra-
tion and a very small PC board footprint.
Propagation delay skew between devices is specified to aid
in parallel interface designs — limits on maximum and mini-
mum delay times are guaranteed.
Five devices can implement a complete SCSI initiator or tar-
get 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.
Features
n Pinout for SCSI interface
n Compact 20-pin PLCC or SOIC package
n Meets EIA-485 standard for multipoint bus transmission
n Greater than 60 mA source/sink currents
n Thermal shutdown protection
n Glitch-free driver outputs on power up and down
