NOTES:
2. VS = ±10V, IOUT = 10mA. On resistance derived from the voltage measured across the switch under these conditions.
3. VS = ±14V, VD = 14V.
±
±
4. VS = VD = ±14V.
5. The digital inputs are diode protected MOS gates and typical leakages of 1nA or less can be expected.
6. VS = 1VRMS , f = 500kHz, CL = 15pF, RL = 1K, CL = CFIXTURE + CPROBE, OFF Isolation = 20 Log VS /VD .
7. VS = 0V, CL = 10nF, Logic Drive = 5V pulse. Switches are symmetrical; S and D may be interchanged. Charge Injection = Q = CL x ∆V.
8. VIN = 4V (one input, all other inputs = 0V).
9. VIN = 0.8V (all inputs).
