MC74ACT652NG

Overview

The MC74ACT652NG is an 8-bit non-inverting registered bus transceiver from onsemi's ACT logic series. It features CMOS technology with three-state outputs, designed for bidirectional data transmission in digital circuits. The device operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in a PDIP-24 package. It provides high output current capability of 24mA and functions as a registered buffer for bus-oriented applications.

Feature Summary

• Registered bus transceiver architecture for stable data latching
• Three-state outputs enabling efficient bus line sharing
• Non-inverting signal path for direct data transfer

Applications

• Bidirectional data transmission systems
• Bus-oriented memory interface designs
• Digital circuit buffering and registration

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the ACT series specifications align with the target system voltage requirements. Ensure the PDIP-24 through-hole format is compatible with the intended PCB assembly process. Check for any specific handling precautions related to CMOS devices during storage and installation.

Selection Notes

Select this component when an 8-bit registered transceiver with three-state control is required. The ACT series offers speed performance suitable for standard digital interfaces. Consider the PDIP-24 package if through-hole mounting is necessary for mechanical stability or prototyping purposes. Verify compatibility with existing bus protocols requiring registered data paths.

Part Context

This part belongs to onsemi's MC74ACT family of advanced CMOS logic devices. The ACT series combines the speed of AC logic with the compatibility of standard TTL inputs. As a registered transceiver, it differs from simple buffers by including internal storage elements for data retention during bus transitions.

Replacement Considerations

Compatible substitutes include other 8-bit registered bus transceivers from the same logic family. Verify pinout compatibility before substitution. Ensure the replacement device maintains the same voltage range and output drive capabilities.
