ADM483E集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ADM483E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ADM483E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 ADM483E is a 5 V, low power data transceiver with ±15 kV ESD protection suitable for half-duplex communication on multipoint bus transmission lines. The ADM483E is designed for balanced data transmission and complies with TIA/EIA Standards RS-485 and RS-422, which allow up to 32 transceivers on a bus.

The ADM483E has a low current shutdown mode in which it consumes only 0.1 μA.

Because only one driver is enabled at any time, the output of a disabled or power-down driver is three-stated to avoid overloading the bus.

Drivers are short-circuit current-limited and are protected against excessive power dissipation by thermal shutdown circuitry that places their outputs into a high impedance state. The receiver input has a fail-safe feature that guarantees a logic high output if the input is open circuit.

The ADM483E is fully specified over the industrial temperature ranges and is available in 8-lead SOIC_N packages.
