MAX1488ECPD

Drivers, Receivers, Transceivers Overview

The MAX1488ECPD is a quad, low-power RS-232 line driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +4.5V to +13.2V for VCC and -4.5V to -13.2V for VEE. The device guarantees a data rate of 120kbps with typical positive and negative supply currents of 85µA each under no-load conditions. It features ±15kV ESD protection via Human Body Model and IEC standards. The component is housed in a 14-pin Plastic DIP package and supports an operating temperature range from 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV electrostatic discharge (ESD) protection on transmitter outputs without latch-up risk during ESD events.
• Integrates internal slew-rate limiting circuitry that eliminates the requirement for external capacitors.
• Maintains low power consumption with supply currents below 180µA across the full specified supply voltage range.
• Ensures TTL and CMOS input compatibility with minimal loading effects on the driving logic.

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 or ±15kV ESD Protection standards

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'CPD' corresponds to the 14-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status indicated by the '+' suffix in the final part number. Ensure the design accommodates dual positive and negative supply rails between ±4.5V and ±13.2V for proper operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD protection directly at the interface without additional discrete components. It serves as a direct pin-compatible replacement for legacy drivers such as MC1488, SN75188, and DS1488. Verify that the application environment remains within the 0°C to +70°C operational limits defined for the CPD variant.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX1488 family of RS-232 line drivers. The MAX1488ECPD specifically denotes the commercial grade version packaged in a 14-pin Plastic DIP. Other variants include the ECSD (SO package) and the EE series which support extended industrial temperatures ranging from -40°C to +85°C.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible substitutes include MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. Verify that alternative devices meet the required ±15kV ESD protection specifications and low supply current characteristics before implementation.
