Description
- Product Details
- The ADM483 is a low power differential line transceiver suitable for half-duplex data communication on multipoint bus trans-mission lines. It is designed for balanced data transmission, and complies with EIA Standards RS-485 and RS-422.The part contains a differential line driver and a differential line receiver. Both share the same differential pins, with either the driver or the receiver being enabled at any given time.
- The device has an input impedance of 12 kΩ, allowing up to 32 transceivers on one bus. Since only one driver should be enabled at any time, the output of a disabled or powered-down driver is three-stated to avoid overloading the bus. This high impedance driver output is maintained over the entire common-mode voltage range from –7 V to +12 V.
- The receiver contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).
- The driver outputs are slew-rate limited to reduce EMI and data errors caused by reflections from improperly terminated buses. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit.
- The part is fully specified over the industrial temperature range, and is available in an 8-lead SOIC package.
