MC74ACT652DWR2G

Overview

The MC74ACT652DWR2G is an octal bus transceiver and register manufactured by onsemi, belonging to the 74AC logic series. It features non-inverting polarity and operates within a supply voltage range of 2 V to 6 V. The device provides bidirectional data transfer with three-state outputs, supporting TTL input levels and CMOS output levels. Key electrical characteristics include a maximum propagation delay of 19 ns at 50 pF load, a low-level output current of 24 mA, and a high-level output current of -24 mA. It is housed in a 24-pin SOIC package and functions as a single circuit element.

Feature Summary

• Provides bidirectional octal data transfer between two buses
• Features three-state outputs for efficient bus line driving
• Supports TTL-compatible input logic levels
• Operates with CMOS-compatible output logic levels

Applications

• Bidirectional bus-oriented memory and I/O mapping
• Clock drivers and buffer circuits
• Bus-oriented switches and protocol translators

Procurement Notes

Verify the specific suffix DWR2G against the manufacturer's latest datasheet to confirm pinout compatibility and moisture sensitivity classification. Ensure the procurement channel sources genuine onsemi components to avoid counterfeit risks associated with logic ICs. Confirm that the operating environment remains within the specified temperature and voltage limits defined in the official documentation.

Selection Notes

Select this component when designing systems requiring bidirectional data flow with high drive capability. The wide supply voltage range allows flexibility in mixed-voltage environments. Consider the 19 ns propagation delay for timing constraints. The 24-pin SOIC package is suitable for surface-mount assembly processes requiring standard footprint dimensions.

Part Context

This part belongs to the MC74ACT family of advanced CMOS logic devices from onsemi. These devices are designed for high-speed applications with low power consumption. The ACT series typically offers performance comparable to LS-TTL but with CMOS power advantages. This specific model integrates both transceiver and register functionalities into a single package.

Replacement Considerations

Check for direct equivalents such as the MC74AC652 or other octal bus transceivers with identical pinouts and electrical specifications. Verify that any substitute maintains the same 24-pin SOIC package and supports the required 2 V to 6 V operating range.
