Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74ACT245MG4 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 ~ 5.5V), and package type (20-SOIC surface mount). All substitute parts listed maintain these core electrical and mechanical specifications. Differences in operating temperature range, moisture sensitivity level, and packaging format (cut tape, tube, or reel) do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the widest operating temperature range (-55°C ~ 125°C), the CD74ACT245M96 from Texas Instruments is the direct equivalent with active product status and highest inventory availability. This part maintains identical electrical specifications and MSL rating to the original CD74ACT245MG4.

For applications operating within the -40°C ~ 85°C temperature range, onsemi-manufactured alternatives (MC74ACT245DWR2G, 74ACT245SC, 74ACT245SCX, MC74ACT245DWG) provide functional equivalence with active product status. Selection among onsemi variants depends on packaging format requirements: cut tape and reel formats (MC74ACT245DWR2G, 74ACT245SCX) or tube packaging (74ACT245SC, MC74ACT245DWG).

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical electrical performance within their specified operating ranges.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CD74ACT245MG4 with any of the listed parts?

A: Yes, all listed parts are functionally equivalent for applications operating within the specified temperature range of each substitute. The CD74ACT245M96 is the direct equivalent for full temperature range applications. onsemi parts are equivalent for -40°C ~ 85°C applications.

Q: What is the difference between the Texas Instruments and onsemi versions?

A: Both manufacturers produce the 74ACT245 logic transceiver with identical electrical specifications. The primary differences are operating temperature range (Texas Instruments: -55°C ~ 125°C; onsemi: -40°C ~ 85°C), moisture sensitivity level, and product status. Select based on your application's temperature requirements.

Q: Does packaging format affect electrical performance?

A: No. Cut tape, tube, and reel packaging formats contain identical die and electrical specifications. Packaging selection is based on assembly process requirements and inventory management practices.

Q: Are all parts ROHS3 compliant?

A: Yes, all listed substitute parts maintain ROHS3 compliance and REACH unaffected status.

Q: Which substitute has the best availability?

A: The CD74ACT245M96 (Texas Instruments) has the highest inventory at 15,148 pieces. Among onsemi alternatives, MC74ACT245DWG offers 3,995 pieces in tube packaging.
