description  
2DIR  
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.  
3DIR  
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  
2A  
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 drivers active-high enable and the receivers 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.

(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.

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder  
temperature.
