Notes:
1. 100% tested at 25°C.
2. Adjacent input pair to adjacent output pair. Interfering input is through an open switch.
3. Adjacent input pair to adjacent output pair. Interfering input is through a closed switch.
4. Crosstalk of eight synchronous switching outputs onto single, asynchronous switching output.
5. SNR = 20 * log (714mV / rms noise).
