CD74ACT651M96

Overview

The CD74ACT651M96 is an octal bus transceiver manufactured by Texas Instruments, belonging to the 74ACT logic family. It features inverting functionality and three-state outputs for effective bus management. The device operates within a supply voltage range of 4.5 V to 5.5 V. It supports high-level output currents of -24 mA and low-level output currents of 24 mA. The component is housed in a 20-pin SOIC package and functions reliably across an extended temperature range from -55°C to +125°C.

Feature Summary

• Octal configuration providing eight independent bidirectional data paths
• Inverting logic polarity for signal phase adjustment
• Three-state outputs enabling isolation when disabled
• Extended industrial temperature rating for harsh environments

Applications

• Memory module data bus interfacing
• Microprocessor system address and data buses
• Control signal routing in embedded systems
• Bidirectional level shifting between logic domains

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the ordering part number matches the required tape-and-reel or tube packaging format. Cross-reference the manufacturer date code with current production status to avoid obsolete stock. Confirm RoHS and REACH compliance requirements align with target market regulations before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with inverting characteristics. The ACT series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Verify that the load capacitance and trace lengths are compatible with the specified propagation delay limits. Ensure the power supply decoupling strategy supports the peak current demands during switching transitions.

Part Context

This device is part of the Texas Instruments 74ACT series, which bridges the performance gap between standard TTL and advanced CMOS technologies. The CD74ACT651 specifically addresses applications needing high-speed data transmission with robust noise immunity. It serves as a critical interface element in digital systems requiring reliable bidirectional communication channels.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 74ACT family. Verify that alternative vendors offer equivalent electrical specifications and package dimensions. Ensure any replacement maintains the same inverting logic function and three-state control compatibility.
