Intersil Introduces Industry's First RS-485 Transceivers to Operate at 1.8V
July 12 2012 - 11:00AM
Marketwired
Intersil Corporation (NASDAQ: ISIL) today introduced 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.
Intersil's ISL32600E, ISL32601E, ISL32602E and ISL32603E are
micropower RS-485 transceivers designed for noise-immune data
communication. The ISL32602E and ISL32603E are specified to operate
from a 1.8V to 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 up to 125°C.
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.
Features and Specifications
- Low bus currents present less than a "1/8 unit load" to the
bus. This allows more than 256 transmitters on the network
- Maximum data rates range from 128kbps to 460kbps at operating
temperatures up to 125°C
- Hysteresis of 40mV provides excellent noise immunity
- Slew rate limited drivers reduce EMI
- Small footprint saves up to 50 percent board space in most
applications
Pricing and Availability The ISL3260x
series is available now 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. For more information please visit:
