DS14C88M Equivalent & Substitute Parts

Part Overview

The DS14C88M is a 4/0 RS232 driver interface IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The DS14C88M provides RS232 driver functionality with a supply voltage range of 4.5V to 12.6V and operates across a 0°C to 70°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS14C88M is based on the following critical parameters that must remain consistent:

• Protocol Compatibility: RS232 driver functionality
• Driver/Receiver Configuration: 4/0 (4 drivers, 0 receivers)
• Package Type: 14-SOIC surface mount package with identical 0.154" (3.90mm) width
• Supply Voltage Range: Minimum 4.5V support; substitute parts must support the original operating range
• Operating Temperature: Substitute parts must cover or exceed the 0°C to 70°C range
• Mounting Technology: Surface mount only

All substitute parts listed are manufactured by Analog Devices Inc./Maxim Integrated under the MAX1488 base product number and meet these core substitution criteria. Variants differ in packaging format (Tube vs. Tape & Reel) and operating temperature range extensions.

Parameter Comparison

Engineering Selection Recommendations

All four MAX1488 variants provide direct functional substitution for the DS14C88M with the following considerations:

For Standard Temperature Range Applications (0°C ~ 70°C):

• MAX1488ECSD+ (Tube packaging) or MAX1488ECSD+T (Tape & Reel packaging) are appropriate selections
• Both maintain the original operating temperature specification
• MAX1488ECSD+T is preferred for automated assembly processes requiring tape and reel format

For Extended Temperature Range Applications (-40°C ~ 85°C):

• MAX1488EESD+ (Tube packaging) or MAX1488EESD+T (Tape & Reel packaging) provide broader temperature coverage
• These variants support low-temperature operation down to -40°C and high-temperature operation up to 85°C
• MAX1488EESD+T is preferred for automated assembly processes requiring tape and reel format

Compliance Advantages: All MAX1488 substitutes are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete DS14C88M. Supply voltage compatibility is maintained with the MAX1488 series supporting 4.5V to 13.2V, which encompasses the original 4.5V to 12.6V range.

Frequently Asked Questions (FAQ)

Q: Can MAX1488 variants directly replace DS14C88M in existing designs? A: Yes. All MAX1488 variants maintain identical RS232 driver functionality, 4/0 driver/receiver configuration, and 14-SOIC package geometry. Pin-to-pin compatibility is preserved.

Q: What is the difference between MAX1488ECSD+ and MAX1488EESD+? A: The primary difference is operating temperature range. MAX1488ECSD+ operates from 0°C to 70°C, matching the original DS14C88M specification. MAX1488EESD+ extends the range to -40°C to 85°C for applications requiring broader temperature support.

Q: Should I select Tube or Tape & Reel packaging? A: Tube packaging (MAX1488ECSD+, MAX1488EESD+) is suitable for manual assembly and low-volume production. Tape & Reel packaging (MAX1488ECSD+T, MAX1488EESD+T) is required for automated pick-and-place assembly processes.

Q: Are there any electrical differences between the DS14C88M and MAX1488 substitutes? A: The MAX1488 series provides a higher maximum supply voltage (13.2V vs. 12.6V) and specified data rate performance (120Kbps). These enhancements ensure compatibility with the original design while providing improved specifications.

Q: What is the significance of ROHS3 compliance on the MAX1488 substitutes? A: ROHS3 compliance indicates adherence to current Restriction of Hazardous Substances regulations. The DS14C88M is RoHS non-compliant, making the ROHS3-compliant MAX1488 variants necessary for designs subject to RoHS requirements.

Q: Can I mix packaging formats in production? A: Tube and Tape & Reel formats of the same MAX1488 variant (e.g., MAX1488ECSD+ and MAX1488ECSD+T) are electrically and functionally identical. Packaging format selection should align with assembly process requirements rather than design specifications.
