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 behavior for the K, LO, RX outputs as a function of the output current is shown in Figure 4. Figure 5 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. 7/15 Functional description Figure 3.
