description

The SN751177 and SN751178 dual differential

drivers and receivers are monolithic integrated

circuits that are designed for balanced multipoint

bustransmissionatratesupto10Mbit/s. Theyare

designed to improve the performance of

full-duplex data communications over long bus

lines and meet ANSI Standards TIA/EIA-422-B

and TIA/EIA-485-A and ITU Recommendations

V.10 and V.11.

†

The NS package is only available taped and reeled.

The SN751177 and SN751178 driver outputs provide limiting for both positive and negative currents and

thermal-shutdown protection from line-fault conditions on the transmission bus line.

The receiver features high input impedance of at least 12 kΩ, an input sensitivity of ±200 mV over a

common-mode input voltage range of –12 V to 12 V, and typical input hysteresis of 50 mV. Fail-safe design

ensures that if the receiver inputs are open, the receiver outputs always will be high.

The SN751177 and SN751178 are characterized for operation from –20°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.

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.
