These devices are designed to survive overvoltage faults such as direct shorts to power supplies, miswiring faults, connector failures, cable crushes, and tool mis-applications. They are also robust to ESD events, with high levels of protection to human-body model specifications. These devices combine a differential driver and a differential receiver, whic.
• Bus-Pin Fault Protection to:
– > ±70 V ('HVD1785, 86, 91, 92)
– > ±30 V ('HVD1787, 93)
• Common-Mode Voltage Range (
–20 V to 25 V) More Than Doubles TIA/EIA 485 Requirement
• Bus I/O Protection
– ±16 kV JEDEC HBM Protection
• Reduced Unit Load for Up to 256 Nodes
• Failsafe Receiver for Open-Circuit, Short-Circuit
and Idle-Bus Conditions
• Low Power Consumption
– Low Standby Supply Current, 1 μA Typical
– ICC 5 mA Quiescent During Operation
• Power-Up, Power-Down Glitch-Free Operation
2 Applications
• Designed for RS-485 and RS-422 Networks
