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-VN----o--m-u---t-a---x-

3. S/N = 20 log -V--V--O--O---v---ni--d-o--e--i-so---e--n---r-o-m--i--s˙-s--e---B---(--p=-------p5---)--M--(--2-H----Vz----).
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-Vn----o-m--u---ta---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 tS, DAT and tH, 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 VIH = 3 V and VIL = 1,5 V.
