DS1488N Equivalent & Substitute Parts

Part Overview

The DS1488N is a 4/0 Driver RS232 interface IC manufactured by Texas Instruments in a 14-DIP package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing system support and new designs. The DS1488N operates with a supply voltage range of ±6V to 15V and is rated for 0°C to 75°C operating temperature. As an obsolete product, sourcing alternatives ensures design continuity and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1488N is determined by strict alignment of the following parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 4/0 configuration
• Package / Case: 14-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Functional Type: Driver

All substitute parts listed maintain identical functional specifications (4/0 RS232 driver configuration) and physical packaging (14-DIP through-hole). Voltage supply ranges and operating temperature ranges vary among substitutes and must be evaluated against specific application requirements. Substitute parts are grouped by product status and compliance certifications to facilitate selection based on availability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection among substitute parts should be based on the following criteria:

For Active Product Status: MAX1488ECPD+ and MAX1488EEPD+ are currently in active production status, providing the longest-term availability and supply chain stability. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and are ROHS3 compliant.

For Extended Temperature Range: MAX1488EEPD+ supports -40°C to 85°C operating temperature, exceeding the original DS1488N specification of 0°C to 75°C. MC1488N supports -55°C to 125°C for applications requiring extreme temperature operation.

For RoHS Compliance: All substitute parts except the original DS1488N are ROHS3 compliant, meeting modern regulatory requirements. SN75C188N, MAX1488ECPD+, MAX1488EEPD+, MC1488N, and SN75188N all satisfy RoHS3 compliance.

For Supply Voltage Compatibility: Verify that the application supply voltage falls within the substitute part's specified range. DS1488N operates at ±6V to 15V; substitute parts operate at narrower ranges (±4.5V to 15V for SN75C188N, 4.5V to 13.2V for MAX1488 series, ±7.5V to 15V for MC1488N and SN75188N).

For Last Time Buy Status: SN75C188N, MC1488N, and SN75188N are designated Last Time Buy, indicating limited future availability. These should be considered only if active product alternatives do not meet application requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX1488ECPD+ directly replace DS1488N in existing designs?

A: MAX1488ECPD+ maintains identical 4/0 RS232 driver configuration and 14-DIP package. However, verify that the application supply voltage (4.5V to 13.2V for MAX1488ECPD+) is compatible with the original ±6V to 15V specification. Operating temperature range differs (0°C to 70°C vs. 0°C to 75°C).

Q: What is the difference between MAX1488ECPD+ and MAX1488EEPD+?

A: Both parts are functionally equivalent 4/0 RS232 drivers in 14-DIP packages. The primary difference is operating temperature range: MAX1488ECPD+ operates 0°C to 70°C, while MAX1488EEPD+ operates -40°C to 85°C. Select MAX1488EEPD+ for applications requiring extended low-temperature or high-temperature operation.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts (SN75C188N, MAX1488ECPD+, MAX1488EEPD+, MC1488N, SN75188N) are ROHS3 compliant. The original DS1488N is RoHS non-compliant.

Q: Which substitute part has the longest product lifecycle?

A: MAX1488ECPD+ and MAX1488EEPD+ are designated Active status, indicating ongoing production and the longest available product lifecycle. Parts designated Last Time Buy (SN75C188N, MC1488N, SN75188N) have limited future availability.

Q: Can I use SN75188N or MC1488N as substitutes?

A: Yes, both maintain 4/0 RS232 driver configuration and 14-DIP packaging. SN75188N operates 0°C to 70°C with ±7.5V to 15V supply. MC1488N operates -55°C to 125°C with ±7.5V to 15V supply. Both are Last Time Buy status. Verify supply voltage and temperature requirements match your application.

Q: What packaging options are available for these substitutes?

A: All substitute parts are supplied in 14-DIP (0.300", 7.62mm) through-hole packages, maintaining mechanical compatibility with DS1488N footprints. Packaging format (Tube) is consistent across all substitutes.
