Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4532BPW is determined by strict equivalence across the following critical parameters:

• Circuit configuration (1 x 8:3 priority encoder function)
• Package type (16-TSSOP surface mount)
• Voltage supply range (3V ~ 18V dual supply)
• Operating temperature range (-55°C ~ 125°C)
• Output current specifications (6.8mA high and low)
• Compliance certifications (ROHS3, REACH Unaffected)

The CD4532BPWR meets all these criteria and is identified as the manufacturer-recommended substitute. The primary distinction is packaging format: the CD4532BPW is supplied in standard packaging, while the CD4532BPWR is supplied in Tape & Reel format with active product status.

Parameter Comparison
