Description
General part information
TMUX7308F Series
The TMUX7308F and TMUX7309F are modern complementary metal-oxide semiconductor (CMOS) analog multiplexers in 8:1 (single ended) and 4:1 (differential) configurations. The devices work well with dual supplies (±5 V to ±22 V), a single supply (8 V to 44 V), or asymmetric supplies (such as V DD = 12 V, V SS = –5 V). The overvoltage protection is available in powered and powered-off conditions, making the TMUX7308F and TMUX7309F devices suitable for applications where power supply sequencing cannot be precisely controlled.
The device blocks fault voltage up to +60 V or –60 V relative to ground in both powered and powered-off conditions. When no power supplies are present, the switch channels remain in the OFF state regardless of switch input conditions and logic control status. Under normal operation conditions, if the analog input signal level on any Sx pin exceeds the supply voltage (V DD or V SS) by a threshold voltage (V T), the channel turns OFF and the Sx pin becomes high impedance. When the fault channel is selected, the drain pin (D or Dx) is pulled to the supply (V DD or V SS) that was exceeded.
The low capacitance, low charge injection, and integrated fault protection enables the TMUX7308F and TMUX7309F devices to be used in front end data acquisition applications where high performance and high robustness are both critical. The devices are available in a standard TSSOP package and smaller WQFN package (ideal if PCB space is limited).
