7.4 Device Functional Modes

The HD3SS214 behaves as a two to one or one to two using high bandwidth pass gates. The input ports are selected using the Dx_SEL pin and Dx_SEL pin which are shown in Table 7-1.

(1) Z = High Impedance
(2) OE pin - For normal operation, drive OE high. Driving the OE pin low will disable the switch. Note: The ports which are not selected by the control lines will be in high impedance status.
