SN74HC126PWTG4 Quad Buffer/Line Driver from Texas Instruments
The SN74HC126PWTG4 is a high-performance integrated circuit designed by Texas Instruments (TI), a leader in semiconductor innovation. This particular device features four independent buffer/line drivers with 3-state outputs, making it an excellent choice for driving bus lines or buffering memory address registers. Each buffer has a separate output-enable (OE) input that, when high, disables the output stage by placing it in a high-impedance state. This allows for the connection of multiple outputs to a common bus line without the risk of damaging the outputs or the bus.
Constructed using TI's advanced high-speed CMOS technology, the SN74HC126PWTG4 offers a robust combination of speed and low power consumption. The device operates over a wide voltage range from 2V to 6V, ensuring compatibility with a variety of logic families. This makes it suitable for interfacing with both CMOS and LSTTL logic levels and adaptable to a range of applications in modern electronic systems.
The SN74HC126PWTG4 comes in a TSSOP (Thin Shrink Small Outline Package) with 14 pins, providing a compact footprint that is beneficial for space-constrained applications. The device's balanced propagation delays and output transition times further contribute to its reliable and predictable performance in high-speed digital systems.
Key features of the SN74HC126PWTG4 include:
- Four independent buffer/line drivers with 3-state outputs
