MAX1488EESD

Drivers, Receivers, Transceivers Overview

The MAX1488EESD is a quad, low-power RS-232 line driver designed for EIA/TIA-232 and CCITT V.28 communications in harsh environments. It operates from dual supplies ranging from ±4.5V to ±13.2V with a typical supply current of 85µA per rail. The device guarantees a data rate of 120kbps and features internally controlled slew-rate limiting, eliminating the need for external capacitors. Inputs are TTL and CMOS compatible. Each transmitter output provides ±15kV electrostatic discharge (ESD) protection via Human Body Model and IEC1000-4-2 standards without latchup. It is housed in a 14-pin SO package and supports an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV ESD protection on all pins and outputs, ensuring latchup-free operation during static discharge events.
• Integrates internal slew-rate limiting circuitry to eliminate the requirement for external timing capacitors.
• Features TTL and CMOS compatible inputs with minimal loading effects on the driving logic.
• Maintains guaranteed 120kbps data rates across the full specified operating voltage and temperature ranges.

Drivers, Receivers, Transceivers Applications

• PC Motherboards
• Modems
• Interface Data Terminal Equipment (DTE) with Data Circuit-Terminating Equipment (DCE)
• Equipment requiring compliance with IEC1000-4-2 Level 4 ESD protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESD' confirms the 14-pin Small Outline package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status if required by assembly specifications. Ensure supply voltages match the ±4.5V to ±13.2V operational limits. Check for pin compatibility requirements against legacy MC1488 or SN75188 designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing serial communication interfaces that require robust ESD immunity without external protection components. It is suitable for applications needing low power consumption and direct TTL/CMOS interfacing. Verify that the 120kbps maximum data rate meets system timing requirements. Consider the 14-SOIC footprint constraints during PCB layout.

Drivers, Receivers, Transceivers Part Context

The MAX1488EESD belongs to the MAX1488 family of low-power RS-232 drivers. It serves as a drop-in replacement for older generations like the MC1488 and DS1488 due to pin compatibility. Unlike standard drivers, it integrates significant ESD protection directly into the silicon die, simplifying board-level design for high-reliability industrial and consumer electronics.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. Verify that substitute devices meet the same ±15kV ESD protection and low-power supply current specifications to maintain system reliability.
