Intersil Introduces Industryās Lowest Voltage, Micropower RS-485/RS-422 Transceiver Family
New ISL3261x Family Simplifies Industrial Designs While Improving Reliability
MILPITAS, CA ā (Marketwire) ā 01/24/12 ā Intersil Corporation (NASDAQ: ISIL) today introduced the ISL3261x series of RS-485/RS-422 transmitters and receivers designed to meet the strict power budgets of battery and remote sensing applications. Operating from an industry-low 1.8V supply voltage and consuming less than 150uW, this new family is the optimal solution for designers who need to increase battery life and/or reduce the size of their power supply.
The ISL3261x series includes the ISL32613/14 transmitters and the ISL32610/11/12 receivers. They each operate with voltage ranges from 1.8V to 3.6V, and data rates that reach 256kbps. All of the devices in the series provide 16.5kV ESD protection and operate at up to 125 degrees C, making them ideal for harsh environments and battery-powered or solar-powered sensor applications.
The ISL32613E/14E transmitters consume up to two orders of magnitude less current when operating at 1.8V versus 3.6V. The ISL32610/11/12E receivers feature symmetrical switching points (+/-200mV) and increased hysteresis. The symmetrical switching points eliminate duty cycle distortion introduced by āfull-failsafeā type receivers, while the larger hysteresis increases noise immunity.
Ultra-low bus currents of +/-40uA allow more than 256 transmitters on a network, with no repeaters, while still meeting the RS-485 specificationās 32-unit load maximum.
Features and Specifications
Low quiescent current of 80uA max for transmitters and 110uA max for
receivers
āĀ Wide supply range of 1.8V to 3.6V for maximum flexibility
āĀ High 16.5k ESD protection for enhanced reliability in harsh
environments
āĀ Industrial temp range as well as 12
5 degree C extended high temp
