GENERAL DESCRIPTION  
ADM3491  
The ADM3483/ADM3485/ADM3488/ADM3490/ADM3491 are  
low power, differential line transceivers designed to operate using a  
single 3.3 V power supply. Low power consumption, coupled with a  
shutdown mode, makes the ADM3483/ADM3485/ADM3488/  
ADM3490/ADM3491 ideal for power-sensitive applications.

The ADM3488/ADM3490/ADM3491 feature full-duplex com-  
munication, while the ADM3483/ADM3485 are designed for  
half-duplex communication.  
Figure 3.  
The ADM3483/ADM3488 feature slew rate limited drivers that  
minimize EMI and reduce reflections caused by improperly ter-  
minated cables, allowing error-free data transmission at data rates  
up to 250 kbps.  
in the internal driver circuitry during fault conditions, then the  
thermal shutdown circuit forces the driver output into a high  
impedance state. If the inputs are unconnected (floating), the  
receiver contains a fail-safe feature that results in a logic high  
output state. The parts are fully specified over the commercial  
and industrial temperature ranges. The ADM3483/ADM3485/  
ADM3488/ADM3490 are available in 8-lead SOIC_N; the  
ADM3491 is available in a 14-lead SOIC_N.  
The ADM3485/ADM3490/ADM3491 transmit at up to 10 Mbps.  
The receiver input impedance is 12 kΩ, allowing up to 32 trans-  
ceivers to be connected on the bus. A thermal shutdown circuit  
prevents excessive power dissipation caused by bus contention or  
by output shorting. If a significant temperature increase is detected
