The TS5A23167DCUR by Texas Instruments is a high-performance, dual single-pole, single-throw (SPST) analog switch designed for 1.65-V to 5.5-V single-supply operation. This versatile switch is part of the extensive switch and multiplexer portfolio from Texas Instruments and is known for its low power consumption and high signal integrity.

The device features two normally open (NO) switches that offer low on-state resistance, typically 0.5 Ω at a 2.5-V supply, allowing for efficient signal transfer without significant loss or distortion. This characteristic makes the TS5A23167DCUR an excellent choice for a variety of applications, including signal routing in audio, video, and data communication systems.

The TS5A23167DCUR supports bidirectional signal flow and is compatible with both digital and analog signals. This enables the device to pass signals with amplitudes of up to V+ (supply voltage), which can be as high as 5.5 V. Its low charge injection ensures minimal signal distortion, making it ideal for precision applications.

The switch control inputs (IN1 and IN2) are compatible with 1.8-V logic, allowing for direct interfacing with low-voltage microprocessors and microcontrollers without the need for level shifters. This feature simplifies the design and reduces the overall component count in the system.

The TS5A23167DCUR comes in a compact 8-pin VSSOP package, which makes it suitable for space-constrained applications. The device also features a break-before-make switching mechanism, which prevents signal cross-talk during switching transitions. Its extended industrial temperature range of -40°C to 85°C ensures reliable performance in a variety of environments.

In summary, the TS5A23167DCUR is a reliable and efficient solution for designers looking to manage analog signals in their electronic systems. With its low on-state resistance, compatibility with low-voltage logic, and compact form factor, it is a versatile component that can be used in a multitude of applications.
