Description

The ADM488 and ADM489 are low power differential line transceiver suitable for communication on multipoint bus trans- mission lines.

ADM488 and ADM489 are intended for balanced data transmission and comply with both EIA Standards RS-485 and RS-422. Both products contains a single differential line driver and a single differential line receiver making them suitable for full duplex data transfer.

The ADM488 and ADM489 contain an additional receiver and driver enable control. The input impedance is 12 kΩ, allowing 32 transceivers to be connected on the bus.
