Notes
1. TXD is LOW. Short-circuit protection provided for slew rates up to 5 V/µs for voltages above +30 V.
2. Short-circuit applied when TXD is HIGH, followed by TXD switched to LOW.
3. In accordance with “IEC 60747-1”. An alternative definition of virtual junction temperature is:
Tvj = Tamb + Pd × Rth(vj-a), where Rth(vj-a) is a fixed value to be used for the calculation of Tvj. The rating for Tvj limits
the allowable combinations of power dissipation (Pd) and ambient temperature (Tamb).
4. Classification A: human body model; C = 100 pF; R = 1500 Ω; V = ±2500 V.
5. Classification B: machine model; C = 200 pF; R = 0 Ω; V = ±250 V.
