3 Description
The MUX708-Q1 is an 8:1, 1 channel multiplexer
featuring low on resistance. The device works with a
single supply (4.5V to 44V), dual supplies (±4.5V to
±22V), or asymmetric supplies (such as VDD = 12V,
VSS = –5V). The MUX708-Q1 support bidirectional
analog and digital signals on the source (Sx) and
drain (D) pins ranging from VSS to VDD.
The MUX708-Q1 has low on and off leakage currents
allowing it to be used in high precision measurement
applications. The MUX708-Q1 provides latch-up
immunity, preventing undesirable high current events
between parasitic structures within the device typically
caused by overvoltage events. A latch-up condition
typically continues until the power supply rails are
turned off and can lead to device failure. The latch-up
immunity feature allows the MUX708-Q1 to be used in
harsh environments.
