CD4532BM96 Priority Encoder Equivalent & Substitute Parts

Part Overview

The CD4532BM96 is a priority encoder logic integrated circuit manufactured by Texas Instruments, classified as a 1 x 8:3 priority encoder in the 4000B series. This component is currently active in production and available in 16-SOIC surface mount packaging. Priority encoders are essential in digital logic applications where multiple input signals must be prioritized and converted to a binary output representation. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits equivalent alternatives from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4532BM96 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

  • Circuit configuration: 1 x 8:3 priority encoder function
  • Package type: 16-SOIC surface mount
  • Voltage supply range: 3V ~ 18V dual supply
  • Operating temperature range: -55°C ~ 125°C
  • RoHS compliance: ROHS3 Compliant
  • Moisture sensitivity level: MSL 1 (Unlimited)

Allowable Variations:

  • Manufacturer: Texas Instruments or onsemi (both qualified manufacturers in the 4000B logic series)
  • Packaging format: Tape & Reel (TR), Cut Tape (CT), or Tube
  • Output current specifications: Minor variations acceptable within the 4000B series tolerance (6.8mA to 8.8mA range)
  • Product status: Active or Discontinued at distributor (if base part remains in production)

The substitute parts listed below maintain functional equivalence through identical circuit topology, pinout compatibility, and electrical performance within specified operating conditions.

Engineering Selection Recommendations

Primary Selection (Recommended): CD4532BM96 remains the preferred choice as the original specified part, with active product status and established supply availability.

Secondary Selection (Equivalent Substitute): MC14532BDG and MC14532BDR2G from onsemi are manufacturer-recommended equivalents. Both parts maintain identical functional specifications, package compatibility, and compliance certifications. The onsemi variants feature slightly elevated output current specifications (8.8mA versus 6.8mA), which represents improved drive capability within the 4000B series tolerance envelope. Both parts are currently active in production.

Tertiary Selection (Parametric Equivalent): CD4532BMT is a parametric equivalent from Texas Instruments with identical electrical specifications to the main part. This part is discontinued at DiGi Electronics but may remain available through alternative distribution channels. Selection of this part should be contingent upon availability verification and lead time assessment.

Packaging Considerations:

  • Tape & Reel (TR) format is optimal for high-volume automated assembly
  • Cut Tape (CT) format accommodates moderate-volume requirements
  • Tube packaging is suitable for lower-volume or manual assembly processes

Frequently Asked Questions (FAQ)

Q: Can MC14532BDG or MC14532BDR2G be used as direct replacements for CD4532BM96?

A: Yes. Both onsemi parts are manufacturer-recommended equivalents with identical circuit topology, pinout configuration, and operating specifications. The 16-SOIC package dimensions, voltage supply range (3V ~ 18V), temperature range (-55°C ~ 125°C), and functional performance are fully compatible. The slightly higher output current (8.8mA versus 6.8mA) represents enhanced drive capability and does not create compatibility issues.

Q: What is the difference between CD4532BMT and CD4532BM96?

A: Both are Texas Instruments priority encoders with identical electrical and functional specifications. The primary difference is product status: CD4532BMT is discontinued at DiGi Electronics, while CD4532BM96 remains active. Electrical performance, package type, and compliance certifications are equivalent.

Q: Are there packaging format differences between the substitute parts?

A: Yes. CD4532BM96 is supplied in Tape & Reel format. MC14532BDG is available in Tube packaging, while MC14532BDR2G is supplied in Cut Tape format. All three formats contain identical components; packaging selection depends on assembly volume and handling requirements.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. CD4532BM96, MC14532BDG, and MC14532BDR2G are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: What is the inventory status of these parts?

A: CD4532BM96 has 19,800 pieces in stock. MC14532BDG has 50,400 pieces available. MC14532BDR2G has 4,586 pieces in stock. CD4532BMT has 1,126 pieces available but is discontinued at DiGi Electronics.
