ANALOG DEVICES LTC1480IN8#PBF RS485 Transceiver, 2.5Mbps, Open, 3 to 3.6V, -40°C to 85°C, NDIP-8

LTC1480IN8#PBF is an ultralow power differential line transceiver which provides full RS485 compatibility while operating from a single 3.3V supply. It is designed for data transmission standard RS485 applications with extended common mode range (-7V to 12V). It also meets the requirements of RS422 and features high speed operation up to 2.5Mb/s. The CMOS design offers significant power savings without sacrificing ruggedness against overload or ESD damage. Typical quiescent current is only 300µA while operating and 1µA in shutdown. The driver and receiver feature three-state outputs, with the driver outputs maintaining high impedance over the entire common mode range. Excessive power dissipation caused by bus contention or faults is prevented by a thermal shutdown circuit which forces the driver outputs into a high impedance state. It is used in applications such as battery-powered RS485/RS422 applications, low power RS485/RS422 transceiver, level translator.

• Thermal shutdown protection, upto 32 transceivers on the bus
• Power up/down glitch-free driver outputs permit live insertion or removal of transceiver
• Driver maintains high impedance in three-state or with the power off
• Supply current is 400µA typical at (VCC = 3.3V)
• Supply current in shutdown mode is 1µA typical at (VCC = 3.3V)
• Driver rise or fall time is 15ns typical at (VCC = 3.3V)
• Receiver input hysteresis is 70mV typical at (VCM = 0V, VCC = 3.3V)
• Input current is ±2µA maximum at (DE, DI, RE, VCC = 3.3V)
• Receiver short-circuit current is 85mA maximum at (VCC = 3.3V, 0V ? VO ? VCC)
• Operating temperature range from -40°C to 85°C, 8-lead PDIP package
