SN74HC126DR

The SN74HC126DR is a part of Texas Instruments' 74HC logic family, a high-speed CMOS quad buffer/line driver with 3-state outputs. It features four independent buffer gates, each of which can drive high-performance circuits with a wide supply voltage range of 2V to 6V. The "3-state" term refers to the ability of the outputs to be in one of three states: high, low, or high-impedance. This high-impedance state is particularly useful in bus systems where multiple outputs need to be connected to a single line.
The SN74HC126DR has a low power consumption characteristic while providing significant drive capability, making it suitable for a variety of digital applications. Its inputs are compatible with TTL logic levels, and its outputs can directly drive CMOS loads. The device comes in a small outline package (SOIC), marked as "DR" in the part number, which is ideal for space-constrained applications. This component is commonly used in digital circuits requiring signal buffering, voltage conversion, or isolated signal lines.
