MC74AC241DW

Overview

The MC74AC241DW is an octal bus driver manufactured by onsemi, belonging to the AC logic series. It features eight non-inverting channels with three-state outputs in a 20-pin SOIC surface-mount package. The device operates within a supply voltage range of 2V to 6V and supports single-ended inputs. Key electrical specifications include a maximum propagation delay of 10ns at load capacitance, with output drive capabilities of 24mA low-level and -24mA high-level current. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides eight independent non-inverting buffer channels for signal driving applications
• Features three-state outputs allowing multiple drivers to share a common bus structure
• Supports wide supply voltage operation suitable for various digital logic families
• Utilizes CMOS technology for low static power consumption during steady states

Applications

• Memory address buffering in computer systems
• Clock distribution networks requiring signal isolation
• Bus-oriented transceiver configurations for data transfer
• I/O port expansion in embedded controller designs

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape/reel specifications. Ensure the component meets required environmental standards such as RoHS compliance before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Confirm that the selected variant matches the intended thermal and electrical requirements for the target application environment.

Selection Notes

Select this component when designing circuits requiring octal bus driving with three-state control capabilities. The AC logic family offers a balance between speed and power consumption compared to older HC or HCT families. Consider the 2V to 6V operating range when interfacing with different voltage domains. The SOIC-20 package is suitable for standard surface-mount assembly processes. Evaluate the 10ns propagation delay to ensure it meets the timing constraints of the system clock or data lines.

Part Context

This device is part of onsemi's extensive 74AC logic portfolio, designed for general-purpose digital applications. The AC series represents advanced CMOS technology offering higher speeds than standard AC devices while maintaining low power dissipation. The MC74AC241DW specifically addresses the need for high-density bus interfacing in compact electronic designs. It serves as a fundamental building block for creating complex digital systems requiring reliable signal transmission and isolation.

Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family, such as other manufacturers' 74AC241 variants. Verify that any replacement maintains the same three-state output functionality and voltage range. Ensure the alternative component meets the same thermal and mechanical specifications for the SOIC-20 package.
