{"product_id":"qs5244so","title":"QS5244SO","description":"\u003cp\u003eThe QS5244SO is a dual-channel, non-inverting buffer from Quality Semiconductor. It features 3-State outputs and operates from a 4.75V to 5.25V supply. With a sink current of 15mA and a source current of 64mA, it is well-suited for driving high-current loads such as LEDs and relays. The 20-SOIC package is compact and suitable for space-constrained designs. This buffer is ideal for bus buffering, signal fan-out, and peripheral driving in 5V logic systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Source Current (64mA):\u003c\/strong\u003e Directly drives LEDs and other high-current loads without external drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-State Outputs:\u003c\/strong\u003e Allows multiple devices to share a bus safely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Inverting Buffer:\u003c\/strong\u003e Preserves signal polarity, simplifying design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard 5V Operation:\u003c\/strong\u003e Compatible with legacy 5V logic systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eLED Driving\u003c\/h3\u003e\u003cp\u003eThe QS5244SO's high source current (64mA) makes it ideal for directly driving LED arrays in display panels or indicator lights without additional transistors.\u003c\/p\u003e\u003ch3\u003eBus Buffering\u003c\/h3\u003e\u003cp\u003eUse it to buffer address or data buses in 5V systems.
