Notes

1. The LOW voltage of pin SCLG is influenced by VSCL: VSCLG(LOW) ≥ VSCL(LOW) + 0.22 V.

2. The equivalent level voltage is that value of the level voltage (at pin LEVEL) which results in the same weak signal

control effect (for instance HCC roll-off) as the output value of the specified detector (USN, WAM and MPH).

3. Crosstalk between bus inputs and signal outputs:
