MC74ACT241DTR2G

Overview

The MC74ACT241DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the 74ACT logic family. It features eight non-inverting outputs with 3-state capability, allowing for effective bus-oriented connections. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 9 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 8 uA, with a maximum operating temperature of +85 C and minimum of -40 C. It is housed in a 20-pin TSSOP package.

Feature Summary

• Provides eight non-inverting buffer channels with independent 3-state control for efficient bus management.
• Delivers high drive capability with 24 mA source and sink currents suitable for loading demanding buses.
• Operates reliably across industrial temperature ranges with low static power consumption characteristics.

Applications

• Bus-oriented systems requiring signal buffering and isolation
• Clock drivers for high-speed digital circuits
• Memory module data line drivers

Procurement Notes

Verify the specific ordering suffix DTR2G to confirm the tape and reel packaging format and quantity. Ensure the procurement channel sources genuine onsemi components to guarantee compliance with the specified ACT logic family electrical characteristics and RoHS standards. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit risks.

Selection Notes

Select this component when an octal buffer with 3-state functionality is required for 5V CMOS applications. It is suitable for designs needing high drive strength and fast propagation delays. Consider the TSSOP-20 package constraints for PCB layout. Compare against similar 74ACT series devices if different pin counts or inversion types are needed.

Part Context

This component is part of the extensive 74ACT logic family from onsemi, designed for high-speed CMOS applications. It complements other buffers like the MC74ACT125 and inverters within the same series. The device supports standard 5V logic interfaces, making it compatible with various microprocessor and memory systems utilizing ACT-level signaling standards.

Replacement Considerations

Check for direct equivalents such as the MC74ACT241DR2G or other manufacturers' 74ACT241 variants. Verify that substitute parts maintain the same 20-pin TSSOP footprint and identical 3-state control logic timing specifications to ensure circuit compatibility without redesign.
