• Compliance with RoHS3 and REACH standards

A substitute must meet all of these exact criteria to be considered interchangeable from an engineering perspective.

Parameter Comparison

Engineering Selection Recommendations

The SN74ACT245NG4 is listed as discontinued at Digi-Key, while SN74ACT245N maintains an active product status and matches all compliance requirements, including ROHS3 and REACH. Both parts have identical electrical, mechanical, and packaging parameters as provided, and both are manufactured by Texas Instruments within the same 74ACT series. Selection of SN74ACT245N as a substitute is fully supported by product status and compliance data.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select a substitute for SN74ACT245NG4?
Substitution is based strictly on matching manufacturer, series, logic type, output behavior, number of elements and bits per element, output current, voltage supply range, operating temperature, package type, and compliance certifications.

Q2: Is SN74ACT245N pin-compatible with SN74ACT245NG4?
Both parts use a 20-DIP (0.300", 7.62mm) through-hole package and 20-PDIP supplier device package. Provided parameters confirm physical compatibility.

Q3: Are there differences in electrical performance between SN74ACT245NG4 and SN74ACT245N?
All core electrical characteristics supplied, including output current, voltage supply, and temperature range, are identical between both parts.

Q4: Are both SN74ACT245NG4 and SN74ACT245N compliant with RoHS3 and REACH?
Both parts are identified as ROHS3 compliant and REACH unaffected per the provided parameters.

Q5: What effect does a product's discontinued status have on substitution?
A discontinued status for SN74ACT245NG4 necessitates selection of an active, equivalent substitute such as SN74ACT245N that meets all required technical and compliance criteria.
