TLC7524CN – TEXAS INSTRUMENTS

The Texas Instruments TLC7524CN is a quad SPST analog switch, housed in a space-saving 14-pin SOIC package. Operating from a single 2.7V to 5.5V supply, it features low on-resistance (typically 7Ω) and low charge injection (<5pC), making it suitable for precision analog switching applications. Each switch is independently controlled via CMOS-compatible logic inputs, allowing for flexible signal routing. The device boasts low leakage current (<1nA) and high isolation between channels, minimizing crosstalk and improving signal integrity. Its low on-resistance contributes to minimal signal attenuation, particularly crucial in low-level signal processing._x000D_ _x000D_ Common applications include multiplexing analog sensors, implementing programmable gain amplifiers, and constructing precision data acquisition systems. The TLC7524CN's advantages stem from its combination of low on-resistance, low charge injection, and wide supply voltage range, resulting in superior performance compared to alternatives with higher parasitic capacitances or narrower operating voltages. Its compact SOIC package further enhances its suitability for high-density PCB designs. Careful consideration should be given to the maximum switching frequency (typically 1MHz) when designing high-speed circuits.
