SN74HCT125N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT125N is a quadruple bus buffer gate featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes HCT CMOS logic technology. The device provides four non-inverting input lines corresponding to four output lines, housed in a PDIP-14 package designed for through-hole mounting. Key electrical characteristics include a maximum propagation delay of 36 ns at 4.5 V and 32 ns at 5.5 V. Output drive capabilities are specified with a high-level output current of -6 mA and a low-level output current of 6 mA. The component functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and environmental compliance status. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Check the datasheet for detailed mechanical dimensions and soldering recommendations relevant to the PDIP-14 package before integration into the manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems requiring four buffered signals with tri-state control on a shared bus architecture. The HCT series ensures compatibility with older TTL standards while maintaining CMOS power efficiency. Consider the PDIP-14 through-hole package if prototyping or utilizing legacy board designs that do not support surface-mount technologies.
