description

The SN65LBC171 and SN75LBC171 are

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.

2DE

3DE

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

The SN75LBC171 is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC171

is characterized for operation over the temperature range of –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second).

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
