CD74ACT652EN Equivalent & Substitute Parts

Part Overview

The CD74ACT652EN is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments, designed for 8-bit data transmission with 3-state output capability. This device operates within a 4.5V to 5.5V supply voltage range and is housed in a 24-pin DIP package for through-hole mounting applications.

The CD74ACT652EN is classified as obsolete, which necessitates identification of functionally equivalent substitute components for new designs or production continuity. The primary substitute maintains identical electrical specifications while offering an alternative packaging format suited to modern surface-mount assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74ACT652EN is determined by equivalence in the following critical parameters:

• Base product number (74ACT652) ensures identical logic function and electrical performance
• Identical output current specifications (24mA, 24mA) guarantee load-driving capability
• Matching supply voltage range (4.5V ~ 5.5V) ensures circuit compatibility
• Equivalent operating temperature range (-55°C ~ 125°C) maintains reliability across environmental conditions
• Consistent RoHS3 compliance and MSL rating (1) satisfy regulatory and manufacturing requirements

The CD74ACT652M96 substitute differs only in mounting technology (surface mount versus through-hole) and packaging format (24-SOIC versus 24-DIP), with no degradation of electrical specifications or functional capability.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT652M96 is the direct functional equivalent of the CD74ACT652EN. Selection between these parts is determined by assembly technology and board design requirements rather than electrical performance.

For through-hole assembly processes or legacy board designs, the CD74ACT652EN remains viable where inventory is available. For new designs or surface-mount manufacturing environments, the CD74ACT652M96 is the preferred selection due to its active product status and compatibility with modern assembly techniques.

Both parts maintain ROHS3 compliance and identical electrical specifications, ensuring regulatory conformance and functional interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT652M96 directly replace the CD74ACT652EN in existing designs?

A: Electrical substitution is complete. The CD74ACT652M96 provides identical logic function, output current, supply voltage range, and operating temperature specifications. Physical board layout modification is required due to different package formats (24-SOIC surface mount versus 24-DIP through-hole).

Q: What is the primary difference between these two parts?

A: The CD74ACT652EN uses through-hole mounting in a 24-DIP package, while the CD74ACT652M96 uses surface-mount technology in a 24-SOIC package. All electrical and functional specifications are identical.

Q: Why is the CD74ACT652EN classified as obsolete?

A: The CD74ACT652EN is an older through-hole package variant. Texas Instruments continues to manufacture the 74ACT652 logic function in the more modern CD74ACT652M96 surface-mount package format.

Q: Are there any compatibility concerns when substituting these parts?

A: No electrical compatibility concerns exist. The 24-SOIC package is physically smaller than the 24-DIP package, requiring PCB redesign for pin-to-pad routing and component placement.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the CD74ACT652EN and CD74ACT652M96 are ROHS3 compliant with MSL rating 1 (Unlimited), satisfying identical regulatory and environmental requirements.
