Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1488EEPD is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package type: 14-DIP (0.300", 7.62mm) / 14-PDIP
• Mounting type: Through Hole
• Protocol: RS232
• Driver/Receiver configuration: 4/0 (4 drivers, 0 receivers)
• Pin count and functional pinout alignment

Secondary Compatibility Considerations:

• Supply voltage range overlap with the original specification (4.5V ~ 13.2V)
• Operating temperature range compatibility
• Data rate capability (minimum 120Kbps)
• RoHS and regulatory compliance status

The substitute parts listed below maintain identical package geometry and RS232 driver functionality, enabling direct replacement in through-hole PCB designs. Voltage supply ranges and operating temperature specifications vary among substitutes; selection depends on the specific application requirements and environmental constraints of the target system.

Parameter Comparison

Engineering Selection Recommendations

MAX1488EEPD+ (Analog Devices Inc./Maxim Integrated)

This is the direct successor to the MAX1488EEPD with identical electrical specifications and package configuration. The primary distinction is Active product status and ROHS3 compliance. Selection of MAX1488EEPD+ is appropriate for applications requiring continuity with the original Maxim Integrated design lineage and modern regulatory compliance.

MC1488N (Texas Instruments)

This Texas Instruments equivalent maintains 4/0 driver configuration and 14-DIP package compatibility. The MC1488N operates across an extended temperature range (-55°C to 125°C) and supports a wider supply voltage range (±7.5V ~ 15V). Product status is Last Time Buy. This part is suitable for applications requiring enhanced temperature performance or dual-supply voltage operation.

SN75188N (Texas Instruments)

The SN75188N is a Texas Instruments RS232 driver with identical package and functional configuration. Operating temperature range is 0°C to 70°C with supply voltage specification of ±7.5V ~ 15V. Product status is Last Time Buy. This part is applicable to commercial and industrial temperature range applications.

SN75C188N (Texas Instruments)

The SN75C188N provides the widest supply voltage compatibility (±4.5V ~ 15V) among the listed substitutes, enabling operation across both single and dual-supply configurations. Operating temperature range is 0°C to 70°C. Product status is Last Time Buy. This part is optimal for applications requiring flexible power supply architecture.

Frequently Asked Questions (FAQ)

Q: Can MAX1488EEPD be directly replaced with MAX1488EEPD+?

A: Yes. Both parts share identical electrical specifications, pinout, and 14-DIP package geometry. The primary difference is product status (Obsolete vs. Active) and RoHS compliance. MAX1488EEPD+ is a direct functional equivalent.

Q: What are the key differences between Maxim Integrated and Texas Instruments substitutes?

A: Maxim Integrated parts (MAX1488EEPD+) maintain the original supply voltage range of 4.5V ~ 13.2V. Texas Instruments parts (MC1488N, SN75188N, SN75C188N) operate on dual-supply configurations (±7.5V ~ 15V or ±4.5V ~ 15V). Selection depends on the power supply architecture of the target application.

Q: Which substitute offers the widest operating temperature range?

A: The MC1488N supports -55°C to 125°C, providing the broadest temperature specification among all listed parts. This makes it suitable for industrial and extended-temperature applications.

Q: Are all substitutes available in the same 14-DIP package?

A: Yes. All listed substitutes are packaged in 14-DIP (0.300", 7.62mm) with 14-PDIP supplier designation, enabling direct through-hole PCB replacement without layout modification.

Q: What is the significance of RoHS compliance status?

A: The original MAX1488EEPD is RoHS non-compliant. All listed substitutes (MAX1488EEPD+, MC1488N, SN75188N, SN75C188N) are ROHS3 compliant, meeting modern environmental and regulatory requirements for new designs and production runs.

Q: Can SN75C188N operate with single-supply voltage?

A: Yes. The SN75C188N supports supply voltage range of ±4.5V ~ 15V, enabling operation with single-supply configurations (4.5V to 15V) or dual-supply configurations (±4.5V to ±7.5V). This flexibility makes it suitable for diverse power supply architectures.

Q: What is the product status significance for long-term availability?

A: MAX1488EEPD is Obsolete with limited remaining inventory. MAX1488EEPD+ is Active and recommended for new designs. MC1488N, SN75188N, and SN75C188N are Last Time Buy status, indicating limited future availability. For production continuity, MAX1488EEPD+ is the preferred long-term substitute.
