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 propagation delays ranging from 2.1μs to 5.4μs depending on load capacitance and supply voltage. Power consumption is minimal, drawing less than 180μA per supply rail under no-load conditions. It features ±15kV ESD protection via Human Body Model and IEC standards, latchup immunity, and internally controlled slew-rate limiting that eliminates the need for external capacitors.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV electrostatic discharge (ESD) protection on transmitter outputs without requiring additional external components.
• Features internally controlled slew-rate limiting and current limiting to ensure signal integrity and protect against short circuits.
• Maintains latchup-free operation even during severe ESD events, ensuring robust performance in harsh environments.
• Offers TTL and CMOS compatible inputs with minimal loading, facilitating direct interfacing with standard logic families.

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 requirements

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'SD' package designation corresponds to the 14-pin SOIC format. Ensure compatibility with existing board layouts designed for legacy pin-compatible drivers such as MC1488 or SN75188 before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring quad RS-232 transmission without integrated receivers. It is suitable for applications needing high ESD tolerance and low power consumption. Verify that the system operates within the specified ±4.5V to ±13.2V dual-supply range. Consider the 120kbps maximum data rate limitation for high-speed communication needs.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1488E family of low-power RS-232 line drivers. It serves as a drop-in replacement for older generations of RS-232 transmitters like the MC1488 and DS1488. The device is distinct from receiver-only or transceiver variants, focusing solely on signal transmission for serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. Verify electrical specifications match the original design requirements when substituting these legacy parts.
