MC74HCT241AF

Overview

The MC74HCT241AF is an octal buffer and line driver from the 74HCT logic family, manufactured by onsemi. It features two non-inverting elements with four bits per element, providing tri-state outputs for bus-oriented applications. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 20-SOIC package. It is designed for high-speed digital signal buffering and level conversion between TTL or NMOS interfaces.

Feature Summary

• Provides octal buffering capability through two independent non-inverting elements
• Features tri-state outputs to facilitate efficient bus-oriented system designs
• Ensures compatibility with standard TTL and NMOS logic families

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• TTL to CMOS level translation

Procurement Notes

Verify the specific package variant, as the AF suffix typically denotes the SOEIAJ-20 package, which differs physically from the standard SOIC-20. Confirm moisture sensitivity levels and reflow soldering profiles against the official datasheet before integration into the manufacturing process.

Selection Notes

Select this component when an octal buffer with tri-state control is required for 5V logic systems. It serves as a direct pin-compatible replacement for LS241 devices, offering improved speed and lower power consumption characteristics inherent to the HCT technology while maintaining standard TTL input thresholds.

Part Context

This part belongs to the MC74HCT241A series, which is functionally identical to the LS241 in terms of pinout. The series is categorized under buffers and line drivers within onsemi's logic IC portfolio, specifically designed for applications requiring high-speed data transmission and signal integrity maintenance in digital circuits.

Replacement Considerations

The MC74HCT241ADWR2G is a documented substitute part number available from onsemi, featuring a standard SOIC-20 package instead of the SOEIAJ-20 form factor.
