It provides half-duplex communication with separate driver and receiver enable pins (DE and RE). The DIP-8 package makes it suitable for prototyping and through-hole assembly. The driver output differential voltage is 1.5V minimum into a 54-ohm load (standard RS-485 compliance), and the driver propagation delay is 8ns at 12Mbps. The receiver input impedance is 1\/4 unit load (96k-ohm), allowing up to 128 devices on the bus. The receiver fail-safe ensures R is HIGH when the bus is open or idle. The device provides +\/-16kV HBM ESD protection on the bus pins (Y and Z). The common-mode range is -7V to +12V, suitable for noisy industrial environments. The driver outputs (Y, Z) and receiver inputs are on separate pins (vs the combined A\/B pins on many RS-485 transceivers), allowing full-duplex (4-wire) operation when used as an RS-422 transceiver. In RS-485 half-duplex mode, Y and Z are typically connected to the bus alongside A and B of another transceiver. The supply current is 11mA active and 1uA in shutdown (DE=LOW, RE=HIGH). The device is designed for PROFIBUS, RS-485 multidrop, and RS-422 point-to-point communication. The -P suffix specifies DIP-8 package. The SN65HVD22 is a popular choice for 3.3V Arduino and Raspberry Pi RS-485 shields.","pin_description":"
