GENERAL DESCRIPTION  
The ADM3483E/ADM3486E/ADM3488E/ADM3490E/  
ADM3491E are 3.3 V, low power data transceivers with  
1ꢀ ꢁV EꢂD protection suitable for full- and half-duplex  
communication on multipoint bus transmission lines. They  
are designed for balanced data transmission, and they  
comply with TIA/EIA standards Rꢂ­48ꢀ and Rꢂ-422. The  
ADM3483E/ADM3486E are half-duplex transceivers that  
share differential lines and have separate enable inputs for  
the driver and receiver. The full-duplex ADM3488E/  
ADM3490E/ADM3491E transceivers have dedicated  
differential line driver outputs and receiver inputs. The  
ADM3491E also features separate enable inputs for the  
driver and receiver.

Figure 3.  
The devices have a 12 ꢁΩ receiver input impedance,  
which allows up to 32 transceivers on a bus. Because only  
one driver should be enabled at any time, the output of a  
disabled or powered-down driver is tristated to avoid  
overloading the bus.
