DS3695ATM

• Compliant EIA multipoint bus transmission RS485 and compatible RS-422
• 10 ns driver propagation delay (typical)
• Single +5 V supply
• - The common-mode range of the 7V to +12V bus allows ± 7V bus to differ between devices on the ground
• Thermal shutdown protection
• High impedance with driver tristate or power off throughout the common-mode range, buses allow unused devices on the bus to be shut down
• One driver output and receiver input impedance less than combined with one RS485 unit load allows up to 32 transceivers on the bus
• A typical receiver lags 70 millivolts
• Available in SOIC packages

The DS3695A and DS3696A are high-speed differential three-state ® bus/line transceivers designed to meet the requirements of the RS485 environmental impact assessment standard for extended common-mode range (+12 V to - 7 V). In addition, they are all consistent with the requirements of RS-422.

The driver and receive outputs feature tri-state functionality. The driver output maintains tri-state over the entire +12 V common-mode range of -® 7 V. A bus failure causes excessive power consumption in the device to trigger a thermal shutdown circuit, and the force enters a high-impedance state with the driver output. The DS3696A provides an output pin (TS) for reporting the thermal shutdown of the device. TS is an "open collector" with 10 thousand needles inside Pull-up resistor. This allows multiple devices to perform line or ED lenses with TS outputs.

Both AC and DC specifications guarantee temperatures from 0°C to 70°C and supply voltage ranges of 4.75V to 5.25V.
