SN74AHCT126N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHCT126N is a quad bus buffer gate from the Texas Instruments SN74AHCT126 series, designed for high-speed digital applications. It features four non-inverting buffers with three-state outputs, allowing controlled data flow on buses. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS technology compatible with TTL input levels. Packaged in a 16-pin DIP format, it supports surface mount or through-hole installation depending on the specific variant, though this model typically denotes the DIP package. Key electrical characteristics include an output current capability of 8 mA and a propagation delay of approximately 10 ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact package type and pinout configuration against the official datasheet before integration, as variations exist within the family. Confirm that the operating environment remains within the specified voltage and temperature limits to ensure long-term reliability. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between different logic families requiring level translation or when bus isolation is necessary. The AHCT series offers faster switching speeds compared to standard 74HC devices while maintaining TTL compatibility. Consider the DIP package for prototyping or through-hole designs where mechanical stability is prioritized over board space efficiency. Evaluate power consumption requirements as static current varies with supply voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely adopted 74-series logic family, specifically the advanced high-speed CMOS (AHCT) subset. It serves as a fundamental building block in digital electronics for driving loads and isolating signals. The 'N' suffix typically indicates a plastic dual in-line package, distinguishing it from tape-and-reel or other package variants like PW or NSR. It complements other components in the same series such as inverters and transceivers.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74AHCT126PW or SN74AHCT126NSR for equivalent functionality in different packages. For automotive applications, consider the SN74AHCT126QPWRQ1 which meets AEC-Q100 standards. Generic equivalents from other manufacturers may require verification of pin compatibility and electrical specifications.
