SN65HVD61D屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的SN65HVD61D驅(qū)動(dòng)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(huì)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 SN65HVD61 is designed to meet the

requirements for the driver and receiver circuitry of

the ControlNet coaxial-based physical layer.

These devices are single-channel circuits with one

transceiver for single node operation or distributed

stand-alone applications.

The pull-or-pull transmitter circuit is designed to sink

current from a center-tapped transformer, providing

galvanic isolation from the shared bus.

These devices incorporate a differential receiver (RX)

with the 120 mV sensitivity needed by ControlNet

industrial applications.

A secondary receiver (CD) detects the presence of a

valid positive differential signal.

The third signal receiver function (SIG) provides a

scaled analog output which is proportional to the

differential voltage between XF1 and XF3. This output

can be used for diagnostic purposes.
