RS-485 transceivers boast breakthrough 1.8V operation

Intersil Corp. has unleashed what it said is the industry's first RS-485 transceivers that can operate from supply voltages as low as 1.8V, eliminating the need for a 3.3V or 5V power supply. The ISL32600E, ISL32601E, ISL32602E and ISL32603E are geared for noise-immune data communication, noted the company.

The ISL32602E and ISL32603E are specified to operate from a 1.8-3.6V supply voltage.�At 1.8V, they consume only 105uA quiescent supply current, and shutdown current consumption is an ultra-low 10nA, extending battery life in remotely powered nodes. All versions are ±15kV IEC61000 ESD protected and designed to operate in hostile environments.

The ISL32600E and ISL32601E operate with Vcc ? 2.7V, with a supply current of 80uA when both the transmitter and receiver are enabled.

The low voltage and low quiescent current requirements make the ISL3620x family ideal for applications such as flow meters or security systems, where the voltage and power must be minimal, especially if the application must be intrinsically safe. They can also be designed into process control networks, security camera networks or building environmental control systems.

Receivers included on the ISL3260XE series feature symmetrical switching thresholds and increased hysteresis to improve noise immunity and reduced duty cycle distortion in the presence of slow moving input signals.

The transceivers feature low bus�currents that present less than a "1/8 unit load" to the bus.�This allows more than 256 transmitters on the network. Its maximum�data rates range from 128-460Kb/s at operating temperatures up to�125°C. The ISL3260x series offers hysteresis�of 40mV and a small�footprint that claims to save up to 50 percent board space in most applications.

The ISL3260x series is available in 8-, 10- and 14-lead MSOP and 8- and 14-lead SOIC packages, with prices starting at $1.26 each in 1,000-unit quantities.
