Low quiescent current: 300 µA Designed for RS-485 interface applications - 7 V to 12 V common mode input voltage range Driver maintains high impedance in 3-state or with the power OFF 70 mV typical input hysteresis 30 ns propagation delay, 5 ns skew Operates from a single 5 V supply Current Using the RJ-45 connector (modular jack) designed for keypad connection or the control circuit terminal block on the inverter unit enables functionality expansion for RS-485 communication. The RJ-45 connector also makes it possible to operate the keypad at a remote site. IC485S is a 2-way converter for converting RS-232 signals to and from RS-422/RS-485 signals in long-distance application up to 1200m (4000 ft.). It supports the connection of up to 32 hubs. TIA/EIA-485 and TIA/EIA-422 (also known as RS-485 and RS-422) are wired communication standards published by the Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA). They use differential signaling to enable data transmission over long distances and in noisy industrial The SP481E and SP485E are a family of half-duplex transceivers that meet the specifications of RS-485 and RS-422 serial protocols with enhanced ESD performance. The ESD tolerance has been improved on these devices to over ±15kV for both Human Body Model and IEC61000-4-2 Air IC-485AI User Manual. 5 Overvie Although RS-232 serial ports are found on almost every computer, because of their slo transmission speeds, limited range, and limited netorking capabilities, they are not an effective solution for industrial strength long distance communications systems. IC485S is a 2-way converter for converting RS-232 signals to and from RS-422/RS-485 signals in long-distance application up to 1200m (4000 ft.). It supports the connection of up to 32 hubs. SN65HVD485E Half-Duplex RS-485 Transceiver. 1 Features. •1 Bus-Pin ESD Protection up to 15 kV • 1/2 Unit Load: up to 64 Nodes on a Bus • Bus-Open-Failsafe Receiver • Glitch-Free Power-Up and Power-Down Bus. Inputs and Outputs • Available in Small VSSOP-8 Package • Meets or Exceeds the IC485S converts RS-232 serial interfaces to RS-485/422 serial interfaces for trouble-free data transmission. This 2-in-1 converter converts RS232C to either the RS-485 or RS-422 interface, and is DCE/DTE mode selectable at the flip of a switch, making it easy to change line signals!
