Texas Instruments' TMUX1511 is a versatile switch that provides a 1:1 single-pole, single-throw (SPST) switch configuration with four independently-controlled channels. It is designed using complementary metal-oxide-semiconductor (CMOS) technology, which ensures efficient performance.
The TMUX1511 switch has a wide operating supply voltage range of 1.5 V to 5.5 V, allowing it to be used in various applications such as servers, communication equipment, and industrial systems. This flexibility makes it a reliable choice for different industries.
One key feature of the TMUX1511 switch is its powered-off protection capability. When the supply voltage (VDD) is removed and set to 0 V, the switch provides protection up to 3.6 V on the signal path. This feature prevents any potential damage to the system by isolating the switch from back-powering the supply rail through an internal electrostatic discharge (ESD) diode.
Additionally, the TMUX1511 switch is equipped with fail-safe logic circuitry. This means that voltages on the logic control pins can be applied before the supply pin, protecting the device from any potential damage. The logic control inputs have 1.8 V logic-compatible thresholds, ensuring compatibility with both transistor-transistor logic (TTL) and CMOS logic when operating within the valid supply voltage range.
In summary, the Texas Instruments TMUX1511 switch is an excellent choice for applications requiring high-performance switches with powered-off protection. Its wide operating supply voltage range, powered-off protection capability, and fail-safe logic circuitry make it suitable for use in servers, communication equipment, and industrial applications.
