SN65HVD1794D Datasheet PDF - TI

●DESCRIPTION

●These devices are designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring 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.

●FEATURES

●• Bus-Pin Fault Protection to > ±70 V

●• Cable Invert Function Allows Correction for Reversed Bus Pins

●• 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

●– ICC 5 mA Quiescent During Operation

●• Power-Up, Power-Down Glitch-Free Operation

●APPLICATIONS

●• Designed for RS-485 and RS-422 Networks
