The SP485REP-L is a 1/10th unit load RS-485 Transceiver offers high receiver input impedance. It is a pin-to-pin equivalent to our existing SP485 product. The higher receiver input impedance allows for connecting over
400 transceivers on a single transmission line without de
grading the RS-485 driver signal. The SP485R contains a half-duplex driver and receiver with tri-state control. However, the SP485R is intended for increased connections on a single bus compared to the original RS-485 specification. The RS-485 standard is ideal for multi-drop applications where one bus can contain many drivers and/or receivers. The RS-485 standard implementation allows up to 32 transceivers to be connected on to the data bus. RS-485 is also specified for driving higher speeds over long c
able lengths of up to 4000ft. The SP485R exceeds the standard by allowing up to 400 receivers to share the bus.
