Intersil's latest RS-485/RS-422 transmitters and receivers are designed for battery-powered or solar-powered sensing applications.
Operating from an industry-low 1.8V supply voltage and consuming less than 150µW, 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 256kbit/s.
All of the devices in the series provide 16.5kV ESD protection and operate at up to 125 deg C, making them suitable 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 “full-failsafe” type receivers, while the larger hysteresis increases noise immunity.
Ultra-low bus currents of ±40µA allow more than 256 transmitters on a network, with no repeaters, while still meeting the RS-485 specification’s 32-unit load maximum.
