CD74ACT651M96E4

Overview

The CD74ACT651M96E4 is an octal bus transceiver manufactured by Texas Instruments, belonging to the ACT logic series. It features inverting functionality with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high-level output current of -24 mA and low-level output current of 24 mA, with a typical propagation delay of 12.5 ns. It is housed in a 24-pin SOIC package and supports operating temperatures from -55°C to +125°C.

Feature Summary

• Octal non-inverting bus transceiver architecture
• Three-state output capability for bus isolation
• ACT logic family performance characteristics

Applications

• High-performance memory decoding systems
• Data-routing applications requiring short propagation delays
• Bus-oriented memory and command decoders

Procurement Notes

Verify the specific suffix E4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the M96 variant corresponds to the narrow SOIC-24 package dimensions. Ensure compatibility with system voltage levels before integration. Check for obsolescence notices or lifecycle status updates directly from Texas Instruments official channels prior to final procurement decisions.

Selection Notes

Select this component when designing systems requiring octal data transfer with inverting logic functions. The ACT series offers improved speed over standard HC devices while maintaining CMOS power efficiency. Verify that the 4.5V to 5.5V supply range aligns with the target system's power rails. Consider the thermal dissipation capabilities of the SOIC-24 package for high-density PCB layouts.

Part Context

This part belongs to the Texas Instruments CD74ACT family of high-speed CMOS logic devices. The ACT series was designed to provide performance comparable to TTL circuits while offering the low power consumption advantages of CMOS technology. The CD74 prefix denotes commercial temperature range availability within the broader SN74ACT product line.

Replacement Considerations

Direct pin-compatible substitutes may include other octal bus transceivers from the same ACT family, such as the CD74ACT646 for non-inverting applications. Verify logical inversion requirements carefully when selecting alternatives. Cross-reference datasheets for exact electrical parameter matching.
