MAX1488ECSD

Drivers, Receivers, Transceivers Overview

The MAX1488ECSD 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 internally controlled slew-rate limiting and current limiting without requiring external capacitors. The component is housed in a 14-pin SO package and supports an operating temperature range from 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV ESD protection on transmitter outputs via Human Body Model, IEC Contact Discharge, and Air-Gap methods.
• Eliminates the need for external capacitors through integrated internal slew-rate limiting circuitry.
• Maintains latchup-free operation even during electrostatic discharge events.
• Features TTL and CMOS compatible inputs with minimal loading requirements.

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 suffix 'C' indicates the commercial temperature range of 0°C to +70°C, distinct from the industrial 'E' variant. Confirm the 'S' suffix corresponds to the 14-pin Small Outline package type. Ensure compatibility with existing board layouts designed for legacy pin-compatible drivers such as MC1488 or SN75188 before finalizing procurement orders.

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 low power consumption during idle states while maintaining guaranteed transmission speeds up to 120kbps. Verify that the required operating environment falls within the commercial temperature limits rather than the extended industrial range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1488E family of quad line drivers designed for harsh environments. It serves as a direct replacement for older generation drivers like the MC1488 and DS1488. The device simplifies design by integrating protection and control features typically handled by external circuits in previous generations of RS-232 transceivers.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. Verify that substitute parts meet the same ±15kV ESD withstand requirements and supply voltage specifications to ensure functional equivalence in existing designs.
