description

NC
The SN65LBC170 and SN75LBC170 are
3D
monolithic integrated circuits designed for
bidirectional data communication on multipoint
bus-transmission lines. Potential applications
include serial or paralleldatatransmission, 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.

NC – No internal connection

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.
2DIR

2B
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 V = 0. These
CC
ports feature a wide common-mode voltage range
making the device suitable for party-line
applications over long cable runs.

description (continued)
The driver’s active-high enable and the receiver’s active-low enable are tied together internally and provide a
direction input for each driver/receiver pair.
The SN75LBC170 is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC170
is characterized for operation over the temperature range of –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential I/O bus voltages, are with respect to network ground terminal.
2. Tested in accordance with JEDEC Standard 22, Test Method A114–A.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder
temperature.
