Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74ACT245SM96 is determined by the following critical parameters that must remain constant across equivalent parts:

• Base product number (74ACT245) ensures identical logic function and pin configuration
• Logic type (Transceiver, Non-Inverting) and bit configuration (1 Element, 8 Bit per Element) maintain functional equivalence
• Output type (3-State) and output current specifications (24mA, 24mA) ensure electrical compatibility
• Supply voltage range (4.5V ~ 5.5V) defines operational voltage compatibility
• RoHS3 compliance and MSL rating (1) maintain regulatory and environmental standards

Package variations (20-SSOP versus 20-TSSOP) are permitted substitutions when PCB layout and assembly equipment accommodate the dimensional differences. Operating temperature range variations are acceptable when the application environment falls within the substitute part's specified range.

Parameter Comparison

Engineering Selection Recommendations

Both the CD74ACT245SM96 and 74ACT245MTCX maintain Active product status and ROHS3 compliance, confirming long-term availability and regulatory alignment. The primary distinction between these parts is the operating temperature range and package footprint.

The CD74ACT245SM96 supports extended temperature operation from -55°C to 125°C, suitable for industrial and military-grade applications. The 74ACT245MTCX operates within -40°C to 85°C, appropriate for commercial and consumer-grade applications.

Package selection between 20-SSOP and 20-TSSOP depends on PCB design constraints and assembly capabilities. The 20-TSSOP variant (74ACT245MTCX) features a narrower body width (4.40mm versus 5.30mm), enabling higher component density on compact layouts. Both packages maintain identical pin pitch and electrical connectivity.

Selection should be based on application temperature requirements and available PCB real estate. Both parts satisfy identical electrical specifications and logic functionality.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT245MTCX replace the CD74ACT245SM96 in all applications?

A: Functional and electrical compatibility is maintained. Substitution is valid when the application environment operates within the 74ACT245MTCX temperature range (-40°C to 85°C) and PCB layout accommodates the 20-TSSOP package footprint.

Q: What is the difference between 20-SSOP and 20-TSSOP packages?

A: Both packages contain 20 pins with identical pitch and electrical connectivity. The 20-TSSOP has a narrower body width (4.40mm) compared to 20-SSOP (5.30mm), allowing for increased component density. Pin configuration and spacing remain identical.

Q: Are both parts RoHS compliant?

A: Both the CD74ACT245SM96 and 74ACT245MTCX are ROHS3 compliant and carry MSL rating 1 (Unlimited), meeting current environmental and regulatory standards.

Q: What determines if a substitute part is electrically compatible?

A: Electrical compatibility is ensured when the substitute maintains identical base product number (74ACT245), logic type (Transceiver, Non-Inverting), bit configuration (8 bits per element), output type (3-State), output current (24mA), and supply voltage range (4.5V ~ 5.5V).

Q: Can I use the 74ACT245MTCX in applications requiring -55°C operation?

A: No. The 74ACT245MTCX minimum operating temperature is -40°C. For applications requiring -55°C operation, the CD74ACT245SM96 is the appropriate selection.
