SN65LBC170,SN75LBC170,pdf(TRIP

The SN65LBC170 and SN75LBC170 are
monolithic integrated circuits designed for
bidirectional data communication on multipoint
bus-transmission lines. Potential applications
include serial or parallel data transmission, cabled
peripheral buses with twin axial, ribbon, or
twisted-pair cabling. These devices are suitable
for FAST-20 SCSI and can transmit or receive
data pulses as short as 25 ns, with skew less
than 3 ns.
These devices combine three 3-state differential
line drivers and three differential input line
receivers, all of which operate from a single 5-V
power supply.
The driver differential outputs and the receiver
differential inputs are connected internally to form
three differential input/output (I/O) bus ports that
are designed to offer minimum loading to the bus
whenever the driver is disabled or VCC = 0. These
ports feature a wide common-mode voltage range
making the device suitable for party-line
applications over long cable runs.
