Maxim Integrated Line Transceiver CMOS Inverting 14-Pin SOIC MAX1489EESD+

Maxim Integrated MAX1489EESD+ line transceiver is a high-performance CMOS inverting interface IC housed in a 14-pin SOIC surface mount package. It belongs to the CMOS/TTL logic family and functions as a receiver, driver, converter, and line driver optimized for data communication applications. With a low 260µA supply current and a maximum propagation delay of 4 microseconds, the device ensures efficient performance with minimal power consumption.

The device supports a wide supply voltage range from -0.3V up to 7V and operates effectively across an industrial temperature range of -40°C to 85°C, making it suitable for harsh and demanding environments. Its inverting polarity, single-ended input, and CMOS output provide reliable signal conversion and transmission.

Enhanced electrostatic discharge protection withstands ±15kV Human Body Model, ±8kV contact discharge, and ±15kV air-gap discharge, ensuring robust operational reliability and durability under ESD stress. It is pin compatible with legacy transceivers such as MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89, facilitating seamless upgrades or replacements.

Typical applications include interfacing between Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE), modems, and PC motherboards where reliable line interfacing is critical. Its compact footprint (8.75mm length, 6.2mm width, and 1.75mm height) allows integration into space-constrained electronic designs.
