Intersil's New RS-485/RS-422 Transceivers Deliver Industry's Widest Common-Mode Range, Provide Excellent Reliability

Marketwired
Intersil Corporation (NASDAQ: ISIL), today introduced the
ISL3247xE, ISL3248xE, and ISL3249xE series of robust,
fault-protected RS-485/RS-422 transceivers that combine overvoltage
protection (OVP), high electrostatic discharge (ESD) tolerance and
wide common-mode range. Also featuring low quiescent supply
current, the devices provide maximum transceiver performance with
excellent reliability in harsh operating environment applications
such as security/surveillance cameras, industrial process control
and factory automation networks.
The new ISL3247xE, ISL3248xE and ISL3249xE series delivers the
industry's widest common-mode range (CMR) compared to similar
competitive RS-485 devices. Driver outputs and receiver inputs are
fault-protected against voltages as high as ±60V and are protected
against ESD events up to ±16.5kV, enhancing reliability in harsh
environments. The devices have a quiescent supply current of only
2.3mA, which is 30 percent to 50 percent lower than most
competitive devices.
Features and Specifications The ISL3249xE
and ISL3248xE series combine both ±60V OVP and ±25V CMR, while the
ISL3247xE is rated at ±60V OVP and ±15V CMR. The family provides
designers with a full range of options including slew rate limited
versions, high data rate versions and both half-duplex and
full-duplex configurations.
This new product family includes full fail-safe receiver inputs
ensuring a logic high receiver output if the inputs are shorted,
floating or on an idle bus, eliminating the need for bus-biasing
resistors. A common installation error is swapping the cable data
wires. To address this problem, the ISL3248xE series includes a
polarity reversal feature that can remotely correct for this common
installation error without requiring rewiring of the cable or the
connector.
Pricing and Availability The ISL3247xE,
ISL3248xE and ISL3249xE series are available now in a variety of
packages including 8-pin and 14-pin SOIC and 8-pin MSOP packages.
Pricing starts at $1.40 each in 1,000-piece quantities.
