Transceiver
General Description

The LMS485isa low power differential bus/line transceiver
designedfor high speed bidirectional data communicationon
multipoint bus transmission lines.Itis designedfor balanced
transmission lines.It meets ANSI Standards TIA/EIA
RS422-B, TIA/EIA RS485-A and ITU recommendation and
V.11 and X.27. The LMS485 combinesa TRI-STATE™ dif-
ferential line driver and differential input receiver, bothof
which operate froma single 5.0V power supply. The driver
and receiver havean active high and active low, respec-
tively, that canbe externally connectedto functionasa
direction control. The driver and receiver differential inputs
are internally connectedto form differential input/output (I/O)
bus ports that are designedto offer minimum loadingto bus
whenever the driveris disabledor when VCC= 0V. These
ports feature wide positive and negative common mode
voltage ranges, making the device suitablefor multipoint
applicationsin noisy environments. The LMS485is availablea 8-Pin SOIC and 8-Pin DIP packages.Itisa drop-in
socket replacementto Maxim’s MAX485
Features
Meet ANSI standard RS-485-A and RS-422-B Data rate 2.5 Mbps Single supply voltage operation,5V Thermal shutdown protection Short circuit protection Low power BiCMOS Allowsupto32 transceiverson the bus Open circuit fail-safefor receiver Extended operating temperature range −40˚Cto 85˚C Drop-in replacementto MAX485 Availablein 8-pin SOIC and 8-Pin DIP package
Applications
Low power RS-485 systems Network hubs, bridges, and routers Pointof sales equipment (ATM, barcode scanners,…) Local area networks (LAN) Integrated service digital network (ISDN) Industrial programmable logic controllers High speed parallel and serial applications Multipoint applications with noisy environment
Typical Application

20062601 Typical multipoint applicationis showninthe above figure. Terminating resistors,RT,are typically requiredbut only locatedatthetwo endsofthe cable.
Pullupandpull down resistors maybe requiredattheendofthebusto provide failsafe biasing.The biasing resistors provideabiastothe cable whenall
driversarein TRI-STATE,See National Application Note, AN-847for further information.
