LTC2862AIDD-1#PBF集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

LTC2862AIDD-1#PBF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LTC2862AIDD-1#PBF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。

DESCRIPTION

TheLTC®2862Ais a low power,20Mbpsor250kbpsRS485/RS422 transceiver operating on 3V to 5.5V supplies with ±60V overvoltage fault protection on the interface pins during all modes of operation, including power-down. Improvements were made to the LTC2862 for greater robustness and signal integrity: ±40kV HBM and Level 4 IEC ESD protection on the interface pins; increased resistance to electrical overstress;increased receiver noise immunity; additional receiver noise filtering on the LTC2862A-2; and an improved failsafe function optimized for high speed in the LTC2862A-1 and noise rejection in the LTC2862A-2. Low EMI slew rate limited data transmission is available in the250kbps LTC2862A-2 option, while theLTC2862A-1 operates to 20Mbps.
