Nexperia 74HCT125D Quad Buffer Line Driver SOIC-14

The 74HCT125D from Nexperia is a high-performance Quad Buffer/Line Driver designed for reliable signal buffering and line driving in digital circuits. This non-inverting buffer features 3-state outputs, controlled by individual output enable inputs (nOE), allowing the outputs to enter a high impedance off-state when a high signal is applied to nOE. This functionality is essential for bus-oriented systems and multiplexed applications where multiple outputs may share a common line.

The device includes clamp diodes on all inputs, enabling the use of current limiting resistors to interface with voltages exceeding VCC, providing design flexibility and protection. Compliant with JEDEC standard number 7A, this IC ensures industry-standard performance and compatibility. The 74HCT125D is housed in a compact SOIC-14 package with 14 pins, making it suitable for space-constrained PCB designs.
