74AC241PC Equivalent & Substitute Parts

Part Overview

The 74AC241PC is a non-inverting buffer IC manufactured by onsemi, featuring 2 elements with 4 bits per element and 3-state output capability. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The 74AC241PC operates across a 2V to 6V supply voltage range with 24mA output current capability in both high and low states, housed in a 20-DIP package suitable for through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

SN74AC241N (Texas Instruments) is the primary direct equivalent, maintaining identical part numbering convention and electrical specifications. This part carries Active product status and ROHS3 compliance certification, making it suitable for new designs and production environments requiring current component support.

SN74AC244N and SN74AC244NE4 (Texas Instruments) are parametric equivalents that satisfy all electrical and mechanical requirements. Both parts are Active status with ROHS3 compliance. The SN74AC244NE4 variant represents a specific packaging configuration of the SN74AC244N series.

All three substitute parts are manufactured by Texas Instruments, carry REACH Unaffected status, and share identical ECCN and HTSUS classifications with the original 74AC241PC. Selection between these options depends on availability, packaging preferences (Tube packaging specified for all substitutes), and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74AC241N directly replace 74AC241PC in existing circuits? A: Yes. The SN74AC241N maintains identical electrical specifications, output current ratings, supply voltage range, operating temperature range, and 20-DIP package configuration, enabling direct pin-for-pin substitution.

Q: What is the difference between SN74AC244N and SN74AC241N? A: Both parts are parametric equivalents with identical electrical performance and package specifications. The difference lies in the base product number designation (74AC244 versus 74AC241), though all critical parameters match the original 74AC241PC requirements.

Q: Are the Texas Instruments substitutes compatible with the original onsemi 74AC241PC pinout? A: Yes. All substitute parts use the 20-DIP package with identical pin assignments and electrical characteristics, ensuring full compatibility in through-hole mounting applications.

Q: Why is the original 74AC241PC listed as obsolete? A: Obsolete status indicates the part is no longer manufactured by onsemi. Active equivalent parts from Texas Instruments provide continued access to this buffer functionality for production and maintenance applications.

Q: Do the substitute parts meet current compliance requirements? A: Yes. All Texas Instruments substitutes carry ROHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory standards.
