Notes to DC characteristics

1. At supply voltages (V_CC− V_EE) approaching 2.0 V, the analog switch ON-resistance becomes extremely non-linear.

There it is recommended that these devices be used to transmit digital signals only, when using these supply

voltages.

2. For test circuit measuring R_ONsee Fig.8.
