Description

The TMUX7208 is a precision 8:1, single channel multiplexer featuring low on resistance and charge injection. The TMUX7208 takes one of the eight inputs and connects it to the common output determined by the state of the enable and address pins. The device works with a single supply (4.5 V to 44 V), dual supplies (±4.5 V to ±22 V), or asymmetric supplies (such as VDD = 12 V, VSS = –5 V). The TMUX7208 supports bidirectional analog and digital signals onthe source (Sx) and drain (D) pins ranging from VSS to VDD.

The TMUX7208 is part of the precision switches and multiplexers family of devices and have very low on and off leakage currents allowing them to be used in high precision measurement applications. The TMUX72xx family 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 TMUX72xx family of switches and multiplexers to be used in harsh environments.
