MAX1488EEPD+

Drivers, Receivers, Transceivers Overview

The MAX1488EEPD+ is a quad, low-power RS-232 line driver manufactured by Analog Devices Inc./Maxim Integrated. It operates from dual supplies ranging from ±4.5V to ±13.2V and draws less than 180µA of supply current. The device provides ±15kV ESD protection on transmitter outputs and guarantees a data rate of 120kbps. It features internally controlled slew-rate limiting and current limiting without requiring external capacitors. The component is housed in a 14-pin Plastic DIP package and supports an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV electrostatic discharge (ESD) protection on all transmitter outputs for harsh environments
• Features internally controlled slew-rate limiting and current limiting to eliminate the need for external capacitors
• Maintains latchup-free operation even during ESD events
• Ensures TTL and CMOS input compatibility with minimal loading

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact temperature range and package type. The 'E' suffix indicates industrial temperature range (-40°C to +85°C), while 'C' denotes commercial range. Confirm RoHS compliance status via the datasheet revision history. Ensure the pinout matches legacy MC1488 or SN75188 designs if used as a drop-in replacement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD protection directly at the interface without additional discrete components. It is suitable for applications needing guaranteed 120kbps performance with low power consumption. Verify that the system can provide dual positive and negative supply voltages within the ±4.5V to ±13.2V range. Consider the 14-pin DIP footprint constraints for PCB layout.

Drivers, Receivers, Transceivers Part Context

The MAX1488E belongs to the Maxim Integrated RS-232 driver family, designed for EIA/TIA-232 and CCITT V.28 communications. It serves as a direct pin-compatible replacement for older drivers like the MC1488, MC14C88, SN75188, and DS1488. This lineage ensures backward compatibility for existing hardware designs while offering improved ESD resilience and lower power consumption compared to predecessors.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1488EEPD+ is explicitly documented as pin compatible with the MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88.
