The high output feature of the SN65HVD5x provides

• Low-Current Standby Mode < 1 μA

more noise margin than the typical RS-485 drivers.

• Glitch-Free Power-Up and Power-Down Bus

The extra noise margin makes applications in long

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).

APPLICATIONS

• Utility Meters

• Chassis-to-Chassis Interconnects

• DTE/DCE Interfaces

• Industrial, Process, and Building Automation

• Point-of-Sale (POS) Terminals and Networks

DESCRIPTION

The SN65HVD5X devices are 3-state differential line

drivers and differential-input line receivers that

operate with a 5-V power supply. Each driver and

receiver has separate input and output pins for

full-duplex bus communication designs. They are

designed for balanced transmission lines and

interoperation with ANSI TIA/EIA-485A,

TIA/EIA-422-B, ITU-T v.11 and ISO 8482:1993

standard-compliant devices.

The SN65HVD50, SN65HVD51, and SN65HVD52

are fully enabled with no external enabling pins.

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 the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
