Renesas Electronics Corporation Signal Switches, Multiplexers, Decoders QS3244QG

The QS3244QG is a high-speed CMOS 8-bit bus switch designed for industrial applications, operating within a temperature range of -40¬8C to +85¬8C. It features enhanced N channel FETs with a low ON resistance of 5Oc, allowing for bidirectional connections between inputs and outputs without introducing propagation delay or ground bounce. The device is pin compatible with 74F244, 74FCT244, and 74FCT244T, making it suitable for logic replacement and data processing tasks. This bus switch supports various applications, including hot-swapping, voltage translation (5V to 3.3V), power conservation, capacitance reduction, and clock gating. The QS3244QG includes undershoot clamp diodes on all switch and control inputs, ensuring reliable operation. It is available in QSOP, SOIC, and TSSOP packages, providing flexibility for different design requirements.
