SP505ACM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 SP505 is a monolithic device that supports eight (8) popular serial interface standards for DTE to DCE connectivity. The SP505 is fabricated using a low power BiCMOS process technology, and incorporates a Sipex patented (5,306,954) charge pump allowing +5V only operation. Seven (7) drivers and seven (7) receivers can be configured via software for any of the above interface modes at any time. The SP505 requires no additional external components for compliant operation for all of the eight (8) modes of operation. All necessary termination is integrated within the SP505 and is switchable when V.35 drivers, V.35 receivers, and V.11 receivers are used. The SP505 can operate as either a DTE or DCE.
