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.
