Substitute Part Grouping Explanation

Substitution of the CD74HC237PWG4 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Circuit configuration: 1 x 3:8 decoder/demultiplexer
• Voltage supply range: 2V ~ 6V
• Output current specifications: 5.2mA high, 5.2mA low
• Operating temperature range: -55°C ~ 125°C
• Package type: 16-TSSOP surface mount
• RoHS3 compliance
• Moisture sensitivity level: 1

All identified substitute parts maintain identical electrical performance characteristics and physical package dimensions, ensuring direct functional replacement without circuit redesign. Substitutes are grouped by manufacturer recommendation status and product lifecycle stage.

Parameter Comparison

Engineering Selection Recommendations

CD74HC237PWR (Texas Instruments) is the primary recommended substitute. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. All electrical and mechanical parameters are identical to the CD74HC237PWG4. The packaging format (Cut Tape and Digi-Reel) supports standard procurement workflows.

CD74HC137PW (Texas Instruments) is a secondary equivalent option. This part carries Last Time Buy status, indicating limited future availability. Selection of this part should be evaluated against long-term production requirements and inventory planning.

MC74HC238ADTG (onsemi) provides cross-manufacturer equivalence with identical electrical specifications and 16-TSSOP packaging. This part is classified as obsolete. Selection requires assessment of supply availability and multi-source qualification requirements.

Selection priority should be based on product lifecycle status, with active products preferred for new designs and ongoing production. All three substitutes are electrically and mechanically interchangeable with the CD74HC237PWG4.

Frequently Asked Questions (FAQ)

Q: Can CD74HC237PWR be used as a direct replacement for CD74HC237PWG4?

A: Yes. Both parts share identical electrical specifications (2V ~ 6V supply, 5.2mA output current, -55°C ~ 125°C operating range), circuit configuration (1 x 3:8), and 16-TSSOP package dimensions. The primary difference is product status: CD74HC237PWR is active while CD74HC237PWG4 is obsolete.

Q: What is the difference between CD74HC237PWG4 and CD74HC137PW?

A: Both parts are functionally equivalent 1 x 3:8 decoder/demultiplexers with identical electrical parameters and 16-TSSOP packaging. The base product numbers differ (74HC237 vs. 74HC137), but electrical performance is equivalent. CD74HC137PW carries Last Time Buy status.

Q: Is MC74HC238ADTG from onsemi compatible with the Texas Instruments CD74HC237PWG4?

A: Yes. The MC74HC238ADTG is a cross-manufacturer equivalent with matching electrical specifications, circuit configuration, and 16-TSSOP package. Manufacturer qualification requirements should be evaluated for your application.

Q: What packaging formats are available for substitute parts?

A: CD74HC237PWR is available in Cut Tape (CT) and Digi-Reel formats. CD74HC137PW and MC74HC238ADTG are supplied in Tube packaging. Packaging selection should align with procurement and assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CD74HC237PWR, CD74HC137PW, and MC74HC238ADTG are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the CD74HC237PWG4.
