Texas Instruments CD4028BNSR
CD4028BNSR variants from Texas Instruments
CD4028BNSR Overview
What changes between part numbers, and what to check before you lock the BOM — Signal Switches, Multiplexers and Decoders.
CD4028BNSR is a Texas Instruments order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: SOP | Max Supply Voltage: 18V | Min Supply Voltage: 3V | Number of Channels: 1 | Number of Outputs: 10 | Number of Bits: 10 | Logic Function: Demultiplexer, Decoder | Max Operating Temp: 125°C Other listed variants describe: CMOS BCD-to-Decimal/Binary-to-Octal Decoder/Demultiplexer, 10-Bit, SOP.
Across listed variants, watch these parameters: packages: SOP.
Example MPNs: CD4028BNSRE4, CD4028BNSR.
Key Features
- Footprint / package: SOPSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- Signal Switches, Multiplexers and Decoders — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 CD4028BNSR part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| CD4028BNSRE4 | Package: SOP | Max Supply Voltage: 18V | Min Supply Voltage: 3V | Number of Channels: 1 | Number of Outputs: 10 | Number of Bits: 10 | Logic Function: Demultiplexer, Decoder | Max Operating Temp: 125°C | SOP | Texas Instruments | Active | Compliant | In Stock | |
| CD4028BNSR | CMOS BCD-to-Decimal/Binary-to-Octal Decoder/Demultiplexer, 10-Bit, SOP | - | Texas Instruments | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on CD4028BNSR map to package, grade, and reel options.
CD4028BNSR uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: E4.
Full MPN examples: CD4028BNSRE4.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right CD4028BNSR Signal Switches, Multiplexers and Decoders
Match the footprint first
Packages here: SOP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For CD4028BNSR, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "CD4028BNSR" — include the full suffix (e.g. E4). RFQ with reel/tube preference and required date code.
