Notes to the characteristics
1. Also if the supply is switched off.
2. Caused by drive on any other input at maximum level, measured in B = 5 MHz, source impedance
for the used input 75 Ω,
crosstalk = 20 log _V-----I-V_N----^o--m-^u---^t-a---x-

4. Supply voltage ripple rejection = 20 log _V----V-r---o-^r---ns---u--o--p-u--p-t--pl--y-u----t at f = max. 100 kHz.
5. S/N = 20 log -V--V--_O--^O---n---n-o--o-i-s--m-e----i-nB-˙-˙-a---=-l---(-2-0---0,--5---k--V-H---)-z--.
6. Caused by drive of any other input at maximum level, measured in B = 20 kHz, source impedance
of the used input = 1 kΩ,
crosstalk = 20 log _V-----i-V_n----^o-m--^u---^t_a---x- according to DIN 45405 (CCIR 468).
7. f = 20 Hz to 20 kHz.
8. All outputs are short-circuit proof (static).
9. The inputs and output (apart from SDA, SCL and OFF) withstand tests of MIL-STD-883 C. It is advisable to
connected series resistors to these pins.
10. Timings t_{S, DAT} and t_{H, DAT} deviate from the I²C bus specification. After reset has been activated, transmission may
only be started after a 50 µs delay.
11. I²C bus load conditions are as follows:
4kΩ pull-up resistor to + 5 V; 200 pF to GND.
All values are referred to V_IH = 3 V and V_IL = 1,5 V.
