8.2.2.1 SN65LBC184 Test Description

The SN65LBC184 is tested against the IEC 61000-4-5 recommended transient identified as the combination wave. The combination wave provides a 1.2-/50μs open-circuit voltage waveform and a 8-/20μs short-circuit current waveform shown in Figure 8-4. The testing is performed with a combination/hybrid pulse generator with an effective output impedance of 2Ω. The setup for the overvoltage stress is shown in Figure 8-5 with all testing performed with power applied to the SN65LBC184 circuit.

The SN65LBC184 is tested and evaluated for both maximum (single pulse) as well as life test (multiple pulse) capabilities. The SN65LBC184 is evaluated against transients of both positive and negative polarity and all testing is performed with the worst-case transient polarity. Transient pulses are applied to the bus pins (A and B) across ground as shown in Figure 8-5.
