SP508集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

DESCRIPTION

The SP508 is a monolithic device that supports eight (8) popular serial interface standards for Wide Area Network (WAN) connectivity. The SP508 is fabricated using a low power BiCMOS process technology, and incorporates a Sipex regulated charge pump allowing +5V only operation. Sipexs patented charge pump provides a regulated output of +5.8V, which will provide enough voltage for compliant operation in all modes.
