LTC486CN#PBF

LTC486 is a low power differential bus/line driver designed for multipoint data transmission standard RS485 applications with extended common-mode range (12V to –7V). It also meets RS422 requirements. The CMOS design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage. The driver features 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 widely used in application such as low power RS485/RS422 drivers, level translator etc.

• Single 5V supply
• Thermal shutdown protection
• Power-up/down glitch-free driver outputs permit live insertion/removal of package
• Driver maintains high impedance in three-state or with the power off
• 28ns typical driver propagation delays with 5ns skew
• Supply current is 110µA typ
• Operating temperature is 0°C to 70°C
• Packaging style is 16-lead plastic DIP
