They are intended for balanced data transmission and complywith 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 ADM489 contains an additional receiver and driver enable control.
The input impedance is 12 kohms, allowing 32 transceivers to beconnected on the bus.
The ADM488/ADM489 operates from a single +5 V ± 10% power supply. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. This feature forces the driver output into a high impedance state if during fault conditions a significant temperature increase is detected in the internal driver circuitry.
The receiver contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating). The ADM488/ADM489 is fabricated on BiCMOS, an advanced mixed technology process combining low power CMOS with fast switching bipolar technology.
The ADM488/ADM489 is fully specified over the industrial temperature range and is available in DIP, SOIC and TSSOP packages.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
