LTC1483IN8#PBF

LTC1483IN8#PBF is an ultra-low power differential line transceiver designed for data transmission standard RS485 applications with extended common-mode range (-7V to 12V). It will also meets the requirements of RS422. It features output drivers with controlled slew rate, decreasing the EMI radiated from the RS485 lines, and improving signal fidelity with misterminated lines. The CMOS design offers significant power savings over its bipolar counterparts without sacrificing ruggedness against overload or ESD damage. Typical quiescent current is only 80µA while operating and less than 1µA in shutdown. The driver and receiver feature three-state outputs, with the driver outputs maintaining high impedance over the entire common-mode range. It is used in applications such as battery-powered RS485/RS422 applications, low power RS485/RS422 transceiver, level translator.

• Controlled slew rate driver for reduced EMI, single 5V supply
• 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
• Up to 32 transceivers on the bus, thermal shutdown protection
• Supply current is 300µA typical at (VCC = 5V)
• Supply current in shutdown mode is 1µA typical at (VCC = 5V)
• Maximum data rate is 250 kbits/s minimum at (VCC = 5V)
• Receiver input resistance is 25Kohm typical at (VCC = 5V)
• Input current is ±2µA maximum at (VCC = 5V)
• Operating temperature range from -40°C to 85°C, 8-lead PDIP package
