MAX1489ECSD+T

Drivers, Receivers, Transceivers Overview

The MAX1489ECSD+T is a quad, low-power RS-232 line receiver designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. It operates on a single +5V supply with a typical current consumption of 350µA. The device provides ±15kV ESD protection on all inputs and features input hysteresis and time-domain filtering to eliminate the need for external components. It guarantees a data rate of 120kbps and offers TTL/CMOS compatible outputs. The component is housed in a 14-pin SOIC package and supports an operating temperature range from 0°C to +70°C.

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 reject noise pulses without external components
• Low power consumption with a typical supply current of 350µA
• Pin-compatible replacement for legacy MC1489, SN75189, and DS1489 devices

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 Level 4 ESD standards

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C). Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure the ordering part number matches the required package type and environmental rating before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust RS-232 reception in electrically noisy industrial or consumer environments. It serves as a direct drop-in replacement for older quad receivers like the MC1489E. Consider the 120kbps speed limit and ensure it meets the system's baud rate requirements.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX1489E family of RS-232 interface integrated circuits manufactured by Analog Devices Inc./Maxim Integrated. It functions specifically as a line receiver, providing signal conversion from RS-232 levels to TTL/CMOS logic levels for digital processing.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89.
