ADM1485规格书详情

ADM1485属于集成电路(IC)的驱动器接收器收发器。由亚德诺半导体技术有限公司制造生产的ADM1485驱动器,接收器,收发器该系列产品的主要功能是提供必需的硬件资源,以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异,可能包括诸如瞬态抑制之类的功能,这些功能对于通信用途可能并非绝对必要,但对于可能的使用环境却是明智之选。

GENERAL DESCRIPTION

The ADM1485 is a differential line transceiver suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with both RS-485 and RS-422 EIA Standards. The part contains a differential line driver and a differential line receiver. Both the driver and the receiver may be enabled independently. When disabled, the outputs are three-stated.

The ADM1485 operates from a single 5 V 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 condi tions, a significant temperature increase is detected in the internal driver circuitry.

Up to 32 transceivers may be connected simultaneously on a bus, but only one driver should be enabled at any time. It is important, therefore, that the remaining disabled drivers do not load the bus. To ensure this, the ADM1485 driver features high output impedance when disabled and also when powered down.

This minimizes the loading effect when the transceiver is not being used. The 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 ADM1485 is fabricated on BiCMOS, an advanced mixed technology process combining low power CMOS with fast switching bipolar technology. All inputs and outputs contain protection against ESD; all driver outputs feature high source and sink current capability. An epitaxial layer is used to guard against latch-up.

The ADM1485 features extremely fast switching speeds. Minimal driver propagation delays permit transmission at typical data rates of 30 Mbps while low skew minimizes EMI interference.

The part is fully specified over the commercial and industrial temperature range and is available in PDIP, SOIC, and small MSOP packages.
