Renesas Electronics High-Speed CMOS TTL-Compatible Bus Switch 1 x 1:1, 20-Pin QSOP QS3245QG

Renesas Electronics QS3245QG is a high-performance bus switch IC featuring nine high-speed CMOS TTL-compatible switches arranged in a 1 x 1:1 configuration, housed in a 20-pin QSOP package. It offers low ON resistance of 15 ohms, which allows seamless input to output connection with zero added propagation delay and minimal ground bounce noise, essential for high-fidelity signal transmission in electronic circuits.

This device operates efficiently within a supply voltage range of 2.3 V to 3.6 V and functions reliably across a broad temperature spectrum from -40°C to 85°C, making it suitable for demanding industrial and electronic system environments.

The QS3245QG incorporates enhanced N-channel FET switches without inherent diodes to Vcc, complemented by undershoot clamp diodes on all switch and control inputs, providing enhanced signal integrity and noise suppression. TTL-compatible control inputs facilitate straightforward control in digital designs.

Additional features include zero propagation delay, effective power conservation, and capacitance reduction, promoting energy-efficient and low-latency switching operations. Hot-swapping and voltage translation capabilities enable easy integration with 5 V to 3.3 V digital logic systems, expanding its versatility.

Typical applications include industrial control systems, semiconductor devices, communication equipment, and other electronic systems where reliable bus switching and isolation are critical.
