Description
Product Overview
ADM3068EBRZ is an IEC electrostatic discharge protected RS-485 transceiver. It allows the device to withstand ±12kV contact discharges on the transceiver bus pins without latch-up or damage. It features a VIO logic supply pin that allows a flexible digital interface capable of operating as low as 1.62V. It is suitable for high speed, 50Mbps, bidirectional data communication on multipoint bus transmission lines. It features a 1/4 unit load input impedance that allows up to 128 transceivers on a bus. It offers a low 500Kbps data rate that is suitable for operation over long cable runs. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. Application includes industrial fieldbuses, process control, building automation, PROFIBUS networks, motor control servo drives and encoders.
- Full duplex, 1.62V to 5.5V VIO logic supply
- TIA/EIA RS-485 compliant over full supply range
- 3.0V to 5.5V operating voltage range on VCC
- IEC 61000-4-2 ≥ ±12kV contact discharge, IEC 61000-4-2 ≥ ±12kV air discharge, HBM ≥ ±30kV
- Full hot swap support (glitch free power-up/power-down)
- Maximum data rate is 500kbps min (TA = 25°C, VIO = VCC = 3.3V)
- Full receiver short-circuit, open circuit, and bus idle fail-safe
- Allows connection of up to 128 transceivers onto the bus
- Propagation delay is 220ns typ (54ohm, TA = 25°C, VIO = VCC = 3.3V)
- 14 lead SOIC package, temperature range from -40°C to +125°C
