±15 kV ESD Protected Dual RS-422 Transceiver
The differential driver outputs and receiver inputs feature electrostatic discharge circuitry that provides protection up to ±15 kV HBM and ±8 kV IEC 61000-4-2 (contact and air discharge).
The ADM4168E operates from a single 5 V power supply. Excessive power dissipation caused by bus contention or output shorting is prevented by short-circuit protection circuitry. Shortcircuit protection circuits limit the maximum output current to 150 mA during fault conditions.
The receivers of the ADM4168E contain a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).
The ADM4168E is fully specified over the commercial and industrial temperature ranges and is available in a 16-pin TSSOP package.Applications
- RS-422 interfaces
- High data rate motor control
- Single-ended-to-differential signal conversion
- Point-to-point and multidrop transmission systems
