LINEAR TECHNOLOGY LTC2872IUHF#PBF 收发器, RS232 / RS422 / RS485, 4驱动器, 3V-5.5电源, QFN-38
The is a robust pin-configurable Transceiver supports RS232, RS485 and RS422 standards while operating on a single 3 to 5.5V supply. The LTC2872 can be configured as four RS232 single-ended transceivers or two RS485 differential transceivers or combinations of both, on shared I/O lines. Pin-controlled integrated termination resistors allow for easy interface reconfiguration, eliminating external resistors and control relays. Half-duplex switches allow four-wire and two-wire RS485 configurations. Loopback mode steers the driver inputs to the receiver outputs for diagnostic self-test. The RS485 receivers support up to 256 nodes per bus and feature full failsafe operation for floating, shorted or terminated inputs. An integrated DC/DC boost converter uses a small inductor and one capacitor, eliminating the need for multiple supplies for driving RS232 levels.
