MAX1488ECSD+T

Drivers, Receivers, Transceivers Overview

The MAX1488ECSD+T is a quad, low-power RS-232 line driver designed for EIA/TIA-232 and CCITT V.28 communications in harsh environments. It operates on dual supplies ranging from ±4.5V to ±13.2V with a typical supply current of 85µA. The device provides ±15kV ESD protection via Human Body Model and IEC standards. It guarantees a data rate of 120kbps and features internally controlled slew-rate limiting without external capacitors. Inputs are TTL/CMOS compatible. The component is housed in a 14-pin SOIC package and operates within a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15kV electrostatic discharge protection on all outputs
• Internal slew-rate limiting eliminates the need for external capacitors
• Low power consumption with minimal loading on TTL/CMOS inputs
• Latchup-free operation during ESD events

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. The 'C' suffix indicates commercial grade (0°C to +70°C), while 'E' denotes extended grade (-40°C to +85°C). Ensure the '+T' designation matches the required reel packaging format for surface-mount assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD tolerance and low power dissipation for RS-232 transmission. It serves as a direct pin-compatible replacement for legacy drivers like MC1488 and SN75188. Verify that the system voltage rails fall within the ±4.5V to ±13.2V range and that the 120kbps data rate meets application requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1488E family of RS-232 line drivers manufactured by Analog Devices / Maxim Integrated. The ECSD variant specifically refers to the commercial temperature range version packaged in a 14-pin Small Outline (SO) format. It is distinct from the DIP package versions and the extended temperature EE series.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. These parts can be considered for direct substitution if electrical parameters align with the design specifications.
