{"product_id":"mc74hc126adt","title":"MC74HC126ADT","description":"\u003cp\u003eThe MC74HC126ADT is a high-speed CMOS quad buffer featuring non-inverting outputs with 3-state capability. Operating from 2V to 6V, it provides a versatile solution for bus-oriented systems, signal buffering, and level shifting. Each of the four channels can source or sink 7.8mA, making it suitable for driving LEDs and other moderate loads. Housed in a compact 14-TSSOP package, this buffer is ideal for space-constrained designs in industrial control, consumer electronics, and communication equipment.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide 2V to 6V Supply Range:\u003c\/strong\u003e Compatible with both 3.3V and 5V systems, simplifying mixed-voltage designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-State Outputs:\u003c\/strong\u003e Enables bus multiplexing and reduces power consumption when outputs are disabled.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed CMOS Technology:\u003c\/strong\u003e Provides fast propagation delays while maintaining low power dissipation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Temperature Range (-55°C to 125°C):\u003c\/strong\u003e Suitable for automotive and industrial environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBus Line Driving\u003c\/h3\u003e\u003cp\u003eThe 3-state outputs allow multiple MC74HC126ADT devices to be connected to a common data bus.
