LTC1483CN8#PBF

LTC1483 is an ultra-low power differential line transceiver designed for data transmission standard RS485 applications with extended common-mode range (-7V to 12V). It 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. 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 application such as battery-powered RS485/RS422 applications, low power RS485/RS422 transceiver, level translator etc.

• Supply current is 80µA typical at (no load, output disabled, VCC = 5V)
• Supply current in shutdown mode is 1µA typical at (DE = 0, RE = VCC, VCC = 5V)
• Single 5V supply, thermal shutdown protection
• 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
• Upto 32 transceivers on the bus
• Pin compatible with the LTC485
• Operating temperature is 0°C to 70°C
• Package style is 8-lead PDIP
