CD74ACT245M Equivalent & Substitute Parts

Part Overview

The CD74ACT245M is a non-inverting transceiver logic IC manufactured by Texas Instruments, designed for 8-bit data bus applications with 3-state output capability. This device operates across a 4.5V to 5.5V supply voltage range and is housed in a 20-SOIC surface mount package. The CD74ACT245M is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74ACT245M is determined by strict equivalence across the following parameters: base product number (74ACT245), logic type (non-inverting transceiver), element and bit configuration (1 element, 8 bits per element), output type (3-state), output current specifications (24mA high and low), supply voltage range (4.5V to 5.5V), and package type (20-SOIC surface mount). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability within the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the widest operating temperature range (-55°C to 125°C), CD74ACT245M96 from Texas Instruments is the direct equivalent with active product status and unlimited moisture sensitivity rating. This part maintains identical thermal specifications to the original CD74ACT245M while offering superior availability.

For applications operating within the -40°C to 85°C temperature range, onsemi alternatives (74ACT245SCX, 74ACT245SC, MC74ACT245DWG, MC74ACT245DWR2G) provide active product status and ROHS3 compliance. Selection among onsemi variants depends on packaging requirements: Cut Tape (CT) & Digi-Reel® for automated assembly processes, or Tube packaging for manual handling applications.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can I use onsemi parts as direct replacements for the Texas Instruments CD74ACT245M?

A: Yes, onsemi 74ACT245 variants are functionally equivalent for applications operating within -40°C to 85°C. The CD74ACT245M96 from Texas Instruments is the preferred substitute if your application requires the full -55°C to 125°C temperature range.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tube packaging?

A: Cut Tape and Digi-Reel® packaging are designed for automated pick-and-place assembly equipment. Tube packaging is suitable for manual component handling and lower-volume assembly processes. Electrical performance is identical across all packaging options.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What does MSL rating mean, and why does it differ between parts?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture absorption during storage. MSL 1 (Unlimited) allows indefinite storage without special conditions. MSL 3 (168 Hours) requires controlled storage conditions and must be used within 168 hours of opening the original packaging. Select based on your storage and handling capabilities.

Q: Which substitute part has the best availability?

A: CD74ACT245M96 (Texas Instruments) and MC74ACT245DWG (onsemi) offer the highest inventory levels at 15148 and 3995 units respectively.
