CD4082BM AND Gate IC Equivalent & Substitute Parts

Part Overview

The CD4082BM is a 2-channel AND gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory (738 pcs). The CD4082BM operates across a wide supply voltage range of 3V to 18V and is part of the 4000B logic series, suitable for general-purpose digital logic applications requiring AND gate functionality with 4 inputs per channel.

Substitute parts are necessary due to the Last Time Buy status and limited inventory availability. Alternative sources from active manufacturers ensure continued design support and component availability for new production runs and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4082BM is determined by the following critical parameters:

• Logic Function: AND gate with 2 channels and 4 inputs per channel
• Supply Voltage Range: Minimum 3V to 18V compatibility
• Package Type: 14-SOIC surface mount form factor
• Operating Temperature Range: -55°C to 125°C
• Compliance: ROHS3 compliant, REACH unaffected status

All substitute parts listed maintain identical logic functionality, pin configuration, and package dimensions. Variations in quiescent current, output current, and propagation delay are within acceptable tolerances for 4000B series logic ICs and do not affect functional interchangeability in standard digital logic applications.

Parameter Comparison

Engineering Selection Recommendations

CD4082BM96 (Texas Instruments) is the primary recommended substitute. This part maintains identical electrical specifications and packaging to the original CD4082BM while offering active product status and significantly higher inventory availability (4600 pcs). Both parts are manufactured by Texas Instruments and share the same base product number (CD4082), ensuring design continuity and supply chain consistency.

MC14082BDG (onsemi) provides an alternative from an established logic IC manufacturer. This part maintains full functional compatibility with identical supply voltage range, operating temperature, and package form factor. Higher output current capability (8.8mA vs 3.4mA) may benefit applications requiring increased drive capability. Available in Tube packaging with 2727 pcs in stock.

MC14082BDR2G (onsemi) offers the same electrical and functional characteristics as MC14082BDG but in Cut Tape & Digi-Reel packaging format with the highest inventory availability (18383 pcs). This packaging option is suitable for automated assembly processes.

HEF4082BT,653 (Nexperia USA Inc.) is suitable for applications where the reduced operating temperature minimum of -40°C (versus -55°C) is acceptable. This part offers the fastest propagation delay (45ns) among all listed substitutes and is available in Tape & Reel packaging with 11112 pcs in stock. The maximum supply voltage is limited to 15V, which may restrict use in applications requiring the full 18V range.

Frequently Asked Questions (FAQ)

Q: Can CD4082BM96 be used as a direct replacement for CD4082BM?

A: Yes. CD4082BM96 is a direct functional and pin-compatible substitute. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and use the same 14-SOIC package. The primary difference is packaging format (Cut Tape & Digi-Reel vs Tube) and product status (Active vs Last Time Buy).

Q: What are the key differences between Texas Instruments and onsemi versions?

A: Texas Instruments versions (CD4082BM and CD4082BM96) maintain output current of 3.4mA and propagation delay of 90ns. onsemi versions (MC14082BDG and MC14082BDR2G) provide higher output current of 8.8mA and slightly longer propagation delay of 100ns. Both are functionally compatible for standard logic applications.

Q: Is the Nexperia HEF4082BT,653 suitable for all applications?

A: HEF4082BT,653 is suitable for most applications but has two limitations: maximum supply voltage of 15V (versus 18V for other parts) and minimum operating temperature of -40°C (versus -55°C). Verify your application does not require operation below -40°C or above 15V supply voltage before selection.

Q: What packaging formats are available?

A: CD4082BM and MC14082BDG are available in Tube packaging. CD4082BM96 and MC14082BDR2G are available in Cut Tape & Digi-Reel format. HEF4082BT,653 is available in Tape & Reel format. Select based on your assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts (CD4082BM, CD4082BM96, MC14082BDG, MC14082BDR2G, and HEF4082BT,653) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute offers the best inventory availability?

A: MC14082BDR2G from onsemi offers the highest inventory with 18383 pcs in stock, followed by HEF4082BT,653 with 11112 pcs. Both are suitable for high-volume production requirements.
