MAX1488ECPD+

Drivers, Receivers, Transceivers Overview

The MAX1488ECPD+ 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 without external capacitors. It provides ±15kV ESD protection on transmitter outputs and is latchup-free during ESD events. The component is housed in a 14-pin plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15kV ESD protection on all transmitter outputs
• Internal slew-rate limiting eliminates the need for external capacitors
• TTL and CMOS compatible inputs with minimal loading
• Latchup-free operation even during electrostatic discharge 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 suffix 'CPD' confirms the 14-pin plastic DIP package and commercial temperature range (0°C to +70°C). Ensure the ordering code includes the '+' designation to confirm RoHS compliance status as defined by the manufacturer's packaging standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing serial communication interfaces that require robust ESD immunity without adding discrete protection components. It serves as a direct pin-compatible replacement for legacy drivers like MC1488 or SN75188, simplifying board upgrades while maintaining low power consumption.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1488 family of RS-232 line drivers manufactured by Analog Devices / Maxim Integrated. The CPD suffix specifically denotes the 14-pin plastic DIP package variant with a commercial temperature rating, distinguishing it from extended temperature or surface-mount options within the same product series.
