LTC2870CUFD#PBF, RS-232 Interface IC RS232/RS485 Multiprotocol Trans w/ Int T

Semiconductors\Interface ICs\RS-232 Interface IC LTC2870 is a robust pin-configurable multiprotocol transceiver with integrated termination supporting RS232, RS485, and RS422 protocols. The LTC2870 can be configured as two RS232 single ended transceiver or one RS485 differential transceiver 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 receiver support up to 256 nodes per bus, and feature full failsafe operation for floating, shorted or terminated inputs. Typical applications are software selectable RS232/RS485/RS422 interface, point-of-sale terminals, cable repeaters, protocol translators. • 3V to 5.5V supply voltage • 20Mbps RS485 and 500kbps RS232 • Automatic selection of integrated RS485 (120 ohm) and RS232 (5kohm) termination resistors • Half-/full-duplex RS485 switching • High ESD is ±26kV • Logic loopback mode • 1.7V to 5.5V logic interface • Supports up to 256 RS485 nodes, RS485 receiver failsafe eliminates UART lockup • 28-lead (4mm × 5mm) plastic QFN package • 0°C to 70°C temperature rating
