ST75C176CDR集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

ST75C176CDR屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由意法半導(dǎo)體集團制造生產(chǎn)的ST75C176CDR驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進(jìn)行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

DESCRIPTION

The ST75C176 is al low power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. This transceiver draw 300μA (typ.) of supply current when unloaded or fully loaded with disabled drivers.

It operates from a single 5V supply.

Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that placed the driver 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 ST75C176 is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applciations).
