The LD7575PS Switching Controllers with SOIC-8_150mil RoHS from Leadtrend is a full-duplex, synchronous communication controller. It supports standard half-/full-duplex physical layers such as RS-232, RS-422 and RS-485. It includes a built-in voltage regulator for internal supply and multiple options for digital I/O port/interrupt control. It features a low on-state resistance for faster switching, simultaneous data exchange, advanced power saving/sleep modes, independent-direction GPIO control and an output port protection circuit. Additionally, the LD7575PS is compliant with the RoHS Directive and certified for quality assurance.
