ADM2761E集成電路（IC）的驅動器接收器收發(fā)器規(guī)格書PDF中文資料

ADM2761E屬于集成電路（IC）的驅動器接收器收發(fā)器。由亞德諾半導體技術有限公司制造生產的ADM2761E驅動器，接收器，收發(fā)器該系列產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行通信。確切的功能會因所采用的通信協議而異，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。

GENERAL DESCRIPTION

The ADM2761E/ADM2763E are 500 kbps, 5.7 kV rms, signal isolated RS-485 transceivers that pass radiated emissions testing to the EN 55032, Class B standard with margin on a 2-layer printed circuit board (PCB). These devices are compliant to the RS-485 and RS-422 communication standards. The ADM2761E/ ADM2763E isolation barrier provides robust system level immunity to IEC 61000-4-x system level electromagnetic compatibility (EMC) standards. The devices are suitable for applications that require insulation against working voltages of 1060 V rms and 1500 V dc for the lifetime of the device.

The devices are protected against ≥±12 kV contact and ≥±15 kV air IEC 61000-4-2 electrostatic discharge (ESD) events on the RS-485 A, B, Y, and Z pins. The ADM2763E features a receiver cable invert pin to allow quick correction of the reversed cable connection on the A and B receiver bus pins while maintaining full receiver fail-safe performance.

These devices are optimized for low speed over long cable runs and have a maximum data rate of 500 kbps. The high differential output voltage makes these devices suitable for PROFIBUS? nodes when powered with 5 V on the VDD2 supply. The VDD1 primary supply and VDD2 isolated supply both support a wide range of voltages (1.7 V to 5.5 V and 3.0 V to 5.5 V, respectively). Half-duplex and full duplex device options are available in the industry standard 16-lead, wide body, standard SOIC_W package with 8.3 mm creepage and clearance.
