Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4082BPWRE4 is determined by strict equivalence across the following parameters:

• Logic function: 2-channel AND gate with 4 inputs per channel
• Electrical specifications: 3V ~ 18V supply voltage, 1 µA maximum quiescent current, 3.4mA output current capability, 90ns propagation delay at 15V with 50pF load
• Input/output logic levels: Low 1.5V ~ 4V, High 4.6V ~ 11V
• Operating temperature range: -55°C ~ 125°C
• Package: 14-TSSOP surface mount form factor
• Compliance: ROHS3 compliant, MSL Level 1

The CD4082BPWR meets all these criteria and serves as a direct functional equivalent. Both parts share identical base product number (CD4082) and electrical characteristics, with the primary difference being packaging format and product availability status.

Parameter Comparison

Engineering Selection Recommendations

The CD4082BPWR is the appropriate substitute for the discontinued CD4082BPWRE4. Both parts are manufactured by Texas Instruments with identical electrical and functional specifications. The CD4082BPWR maintains active product status with higher inventory availability (3220 pcs vs. 952 pcs), ensuring supply chain continuity. Both parts carry ROHS3 compliance and MSL Level 1 rating, meeting regulatory and environmental requirements. The packaging formats differ only in tape configuration options, with the substitute offering both Cut Tape and Digi-Reel options for flexible procurement. Pin-to-pin compatibility and identical performance characteristics across all operating parameters support direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can CD4082BPWR replace CD4082BPWRE4 in existing designs?

A: Yes. Both parts are pin-to-pin compatible with identical electrical specifications, logic function, and package dimensions. No circuit redesign is required.

Q: What is the difference between the two part numbers?
