MAX1489ECSD

Drivers, Receivers, Transceivers Overview

The MAX1489ECSD is a quad, low-power line receiver designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. It features ±15kV electrostatic discharge (ESD) protection on each input, with a ±25V input voltage range. The device provides TTL and CMOS compatible outputs and guarantees a data rate of 120kbps. Supply current is typically 350µA at 5V. It operates within a temperature range of 0°C to +70°C and is housed in a 14-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced ESD protection against ±15kV Human Body Model and IEC1000-4-2 discharges without latchup
• Low power consumption with typical supply current of 350µA
• Integrated input hysteresis and time-domain filtering to eliminate external components
• Stable input thresholds ensuring reliable signal reception

Drivers, Receivers, Transceivers Applications

• PC Motherboards
• Modems
• Interfacing Data Terminal Equipment (DTE) with Data Circuit-Terminating Equipment (DCE)
• Equipment requiring IEC1000-4-2 Level 4 ESD protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C). Confirm the package type matches the required PCB footprint. Check RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-232 interfaces requiring robust ESD immunity and low power consumption. Ensure the application environment stays within the 0°C to +70°C operating range. Verify that the 120kbps data rate meets system requirements. Consider pin compatibility with legacy MC1489 or SN75189 designs if migrating existing hardware.

Drivers, Receivers, Transceivers Part Context

The MAX1489E series consists of quad receivers for RS-232 applications. The ECSD variant specifically denotes the commercial temperature grade and small-outline package. It belongs to the broader family of Maxim Integrated interface ICs focused on serial communication reliability.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89. Verify electrical specifications match before substitution.
