MAX1488EESD+

Drivers, Receivers, Transceivers Overview

The MAX1488EESD+ is a quad, low-power RS-232 line driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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. Operating supply currents are typically 85μA for both positive and negative rails. It features ±15kV ESD protection via Human Body Model and IEC standards, latchup immunity, and internal slew-rate limiting. The component is housed in a 14-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Features internally controlled slew-rate limiting to minimize electromagnetic interference.
• Ensures latchup-free operation even during severe ESD events.
• Maintains low power consumption with typical supply currents below 180μA.

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 Level 4 ESD protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm temperature range and packaging type. The 'ESD' suffix indicates an industrial temperature range of -40°C to +85°C and a 14-pin SOIC package. Confirm RoHS compliance status through the manufacturer's current product status reports. Ensure ordering details match the exact part number required for the intended application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD protection for RS-232 interfaces without adding external protection circuitry. It serves as a direct pin-compatible replacement for legacy drivers like MC1488 and SN75188. Consider its low power profile for battery-operated or thermally constrained designs. Verify that the guaranteed 120kbps data rate meets the system's communication speed requirements.

Drivers, Receivers, Transceivers Part Context

The MAX1488E belongs to the Maxim Integrated family of RS-232 interface devices designed for harsh environments. It complements other products like the MAX1489E receiver to form complete transceiver solutions. The series emphasizes reliability and ease of integration by eliminating the need for external capacitors for slew-rate control. It supports standard TTL and CMOS logic inputs for straightforward interfacing.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1488E is pin-compatible with MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. Verify electrical specifications such as output voltage levels and current limits before substituting these legacy parts. Ensure the replacement part supports the required operating temperature range and ESD protection standards for the target application.
