MC74HCT241AN

Overview

The MC74HCT241AN is an octal buffer and line driver from the 74HCT logic family, manufactured by onsemi. It features two non-inverting four-bit buffers with three-state outputs in a 20-pin DIP package. The device operates within a supply voltage range of 4.5V to 5.5V. It supports high noise immunity and low power consumption typical of HCT technology. The component is designed for surface mount or through-hole applications depending on the specific variant, with the AN suffix indicating a plastic dual in-line package.

Feature Summary

• Octal configuration providing eight independent signal paths
• Three-state output capability for bus-oriented systems
• Non-inverting logic function for signal buffering
• CMOS construction ensuring low static power dissipation

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• Data acquisition systems
• Industrial control interfaces

Procurement Notes

Verify the package type matches the required footprint, as the MC74HCT241 series includes both SOIC and DIP variants. Confirm the suffix 'AN' corresponds to the 20-PDIP package for through-hole mounting. Check RoHS compliance status and moisture sensitivity level before integration into the manufacturing process. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V logic systems. The HCT series ensures compatibility with TTL inputs while offering CMOS performance. Consider the DIP-20 package for prototyping or legacy board designs requiring through-hole technology. Evaluate the drive current capabilities against the load requirements of the connected circuitry.

Part Context

This part belongs to the 74HCT241A series of octal buffers. It is functionally similar to other octal bus drivers but distinguished by its specific package and manufacturer specifications. The HCT series bridges the gap between old TTL standards and modern CMOS technologies, providing robust performance in mixed-signal environments.

Replacement Considerations

Compatible substitutes include the SN74HCT241N from Texas Instruments and the HCPL-241 equivalents from other logic manufacturers. Verify pinout compatibility and electrical characteristics such as propagation delay and output current before substitution.
