The TPW4052-SR analog switch is an advanced solution for analog and digital multiplexer/demultiplexer applications. This dual SP4T switch, designed to replace the MC14052BDR2G, brings superior performance and versatility to your projects. Built with an enhanced process, the TPW4052-SR analog switch provides lower power dissipation and high switching speeds, making it an ideal choice for a wide range of applications.
Technical Overview
The TPW4052-SR analog switch is equipped with three digital select inputs (S0, S1), eight independent inputs/outputs (An, Bn), two common input/output (A, B), and a digital enable input (/E). When /E is set to HIGH, the switches are turned off, ensuring a reliable control mechanism. This design allows the TPW4052-SR analog switch to function effectively as both a multiplexer and a demultiplexer, with an input range that extends to the supply limits.
A key feature of this device is its break-before-make switching action. This mechanism prevents momentary shorting when switching between channels, enhancing the reliability and safety of the system. The TPW4052-SR's performance is further highlighted by its low ON-state resistance and fast switching times, making it a robust solution for various applications.
Features
Analog Switch Voltage
The TPW4052-SR analog switch operates at multiple voltage levels, including 3.3V, 5V, 10V, and ±5V. This flexibility in operating voltage makes it suitable for a broad spectrum of applications, from low-power battery-operated devices to higher voltage industrial control systems.
Low ON-State Resistance
One of the standout features of the TPW4052-SR is its low ON-state resistance. At Vs = ±4.5V or 9V, the typical ON-state resistance is 50Ω, while at Vs = 4.5V, it is approximately 60Ω. Even at a lower voltage of Vs = 3V, the resistance remains relatively low at around 300Ω. This low resistance ensures minimal signal loss and higher efficiency in signal transmission.
High Bandwidth
The device boasts a bandwidth of 200 MHz, making it suitable for high-frequency applications. This high bandwidth capability allows the TPW4052-SR to handle a wide range of signals with minimal distortion, ensuring clear and accurate signal processing.
Fast Switching Times
Speed is a crucial factor in many electronic applications, and the TPW4052-SR delivers with fast switching times. The typical turn-on time (tON) is 60ns, and the turn-off time (tOFF) is 50ns. These rapid switching capabilities make the TPW4052-SR suitable for time-sensitive applications where quick response times are essential.
Break-Before-Make Switching
The break-before-make switching action of the TPW4052-SR ensures that one channel is fully disengaged before another channel is engaged. This feature is vital in preventing short circuits and maintaining the integrity of the signals being switched.
Wide Operation Temperature Range
The TPW4052-SR analog switch operates effectively over a broad temperature range from –40°C to 125°C. This wide operating temperature range ensures that the device can perform reliably in various environmental conditions, from industrial settings to outdoor applications.
