Texas Instruments offers the TMUX1072 series, a range of 2-channel, 2:1 analog muxes designed for high-speed applications. These devices not only provide efficient signal switching capabilities but also incorporate advanced features such as overvoltage detection and powered-off protection.
The TMUX1072 analog muxes are versatile, allowing bidirectional signal routing in both 2:1 and 1:2 configurations. This flexibility makes them suitable for various applications where multiple signals need to be selectively routed. Furthermore, these devices support signals beyond the VCC voltage level, accepting inputs up to 5.5 V.
One of the standout features of the TMUX1072 series is its robust overvoltage protection. The I/O pins of these devices can tolerate a maximum of 18 V, ensuring that unexpected voltage spikes or transients do not harm the system. To safeguard against potential damage, automatic shutoff circuitry is employed, cutting off the power when overvoltage conditions occur.
The overvoltage protection offered by the TMUX1072 series is particularly valuable in systems with complex power sequencing requirements. In such systems, certain boards may power up before others are ready to receive signals. The TMUX1072 devices detect and handle overvoltage events, preventing any harm to the components downstream of the switch.
Additionally, the TMUX1072 series incorporates overtemperature detection, ensuring that excessive heat does not compromise the performance or reliability of the devices. If an overtemperature event is detected, the FLT-pin generates an open-drain output signal, alerting the system to take appropriate action.
In summary, the TMUX1072 series from Texas Instruments provides high-speed, 2-channel, 2:1 analog muxes with integrated overvoltage detection and powered-off protection. These devices offer bidirectional signal routing capabilities and can tolerate signals beyond the VCC voltage level. With automatic shutoff circuitry, overvoltage events are handled effectively, safeguarding system components. The overtemperature detection feature further enhances the reliability of these analog muxes.
