MAX1489ECPD+

Drivers, Receivers, Transceivers Overview

The MAX1489ECPD+ is a quad, low-power line receiver designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. It features ±15kV electrostatic discharge (ESD) protection on each receiver input, which also supports a ±25V input voltage range with hysteresis and time-domain filtering. The outputs are TTL and CMOS compatible, ensuring reliable signal transmission. The device guarantees a data rate of 120kbps and operates with a typical supply current of 350µA. It is available in a 14-pin plastic DIP package and maintains pin compatibility with legacy MC1489, SN75189, and DS1489 devices.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced ESD protection rated at ±15kV Human Body Model and ±8kV IEC1000-4-2 contact discharge without latchup
• Integrated input hysteresis and time-domain filtering to eliminate the need for external noise suppression components
• Low power consumption with a typical supply current of 350µA
• Pin-compatible replacement for industry-standard receivers including MC1489, SN75189, and DS1489

Drivers, Receivers, Transceivers Applications

• PC Motherboards
• Modems
• Interfacing Data Terminal Equipment (DTE) with Data Circuit-Terminating Equipment (DCE)
• Equipment requiring compliance with IEC1000-4-2 or ±15kV ESD Protection standards

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific suffix CPD corresponds to the commercial temperature range (0°C to +70°C) and 14-pin Plastic DIP package as documented in the official Maxim Integrated ordering information. Confirm RoHS compliance status through the manufacturer's certification documents before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust RS-232 reception in electrically noisy industrial environments. The integrated filtering and high ESD tolerance reduce bill-of-materials complexity by removing the need for discrete protection circuits. Ensure the application environment remains within the specified 0°C to +70°C operating range for optimal performance.

Drivers, Receivers, Transceivers Part Context

The MAX1489E belongs to the Maxim Integrated RS-232 line receiver family, specifically engineered for durability in harsh conditions. It serves as a direct upgrade to older generation receivers like the MC1489 and SN75189, offering superior static protection and lower power consumption while maintaining identical pinouts for seamless integration into existing designs.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89 due to verified pin compatibility.
