The ISL32173E, ISL32175E and ISL32177E are high data-rate receivers that operate at up to 80Mbps. A maximum propagation delay skew of 8ns guarantees excellent part-to-part matching.
The ISL32273E, ISL32275E and ISL32277E are reduced supply current versions that operate at data rates up to 20Mbps. Each receiver also features low input currents of ±200microAmps, and presents a one-fourth unit load to the RS-485 bus, allowing up to 128 receivers on the bus.
All of the ICs also feature the industry’s best ESD ratings, at ±16.5kV ESD protection, meeting HBM and IEC61000-4-2 standards on receiver inputs. The ISL32177 and ISL32277 include a logic VL supply pin. The VL supply sets the switching points of the enable inputs, and the receiver output’s VOH, to levels compatible with a lower supply voltage in mixed-voltage systems. This built-in voltage level translation eases operation in mixed-supply systems.
Pairing the quad receivers with Intersil’s ISL32172/7/9 or ISL32272/4 quad transmitters enables a full point-to-point 4-channel solution.
The ISL3217x and ISL3227x products are available now in 16-lead narrow SOIC and 16-lead TSSOP packages featuring industry-standard group or paired enables. The ISL32177 and ISL32277 come in compact 4 x 4 24-lead QFN packages, with individual channel and group-enable functions.
