ADG5248FBRUZ

ADG5248F is a 8:1 multiplexer. This device switches one of eight inputs to a common output. Each channel conducts equally well in both directions when on, and each channel has an input signal range that extends to the supplies. The primary supply voltages define the on-resistance profile, whereas the secondary supply voltages define the voltage level at which the overvoltage protection engages. When no power supplies are present, the channel remains in the off condition, and the switch inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed positive fault voltage (POSFV) or negative fault voltage (NEGFV) by a threshold voltage (VT), the channel turns off and that Sx pin becomes high impedance. It is used in application such as analog input/output modules, process control/distributed control systems, data acquisition, instrumentation, avionics, automatic test equipment, communication systems, relay replacement etc.
