Production Information
ESD-Enhanced, Fail-safe, Slew-Rate limited
RS-485/RS-422 Transceivers

Request full datasheet:  Click here 
The GI3485 3.3/5V, half-duplex, ±16kV ESDprotected RS-485/RS-422 compatible transceivers feature one driver and one receiver.

The GI3485 features enhanced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing errorfree transmission up to 500kbps.

The GI3485 feature a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. These devices are intended for halfduplex communications. All driver outputs are protected to ±16kV ESD using the Human Body Model and ±8kV ESD using the Contact Discharge Method.

TheGI3485 is available in an 8-pin SO package. The devices operate over the extended -40°C to +125°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
