After wake up of the system from SB condition the first output signal will have an additional delay time tdtyp ≤ 5µs. The typical output voltage behaviour for the K, LO, RX outputs as a function of the output current is shown in Fig.5. Fig.6 shows a waveform of the output signal when the low level changes from RON ⋅ IOUT to IOUT ⋅ 2 ⋅ RON + UBE state. This variation occurs due to too low output current or after a negative transient forced to the output or to the supply voltage line. 4/10 L9613B Figure 1.
