MAX3314ECKA

Overview

The MAX3314ECKA is a single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an SOT-23-8 surface-mount package. It supports data rates up to 460 kbps and operates with a supply voltage range of 4.75 V to 5.25 V. The device features full-duplex communication with one driver and one receiver. It includes integrated ESD protection rated at 15 kV and draws a typical operating supply current of 30 uA. The component is designed for operation within a temperature range extending down to -40°C.

Feature Summary

• Integrated 15 kV electrostatic discharge protection on all RS-232 signal pins
• Ultra-low power consumption suitable for battery-operated systems
• Single-supply operation compatible with standard 5 V logic levels

Applications

• Portable computers and notebook PCs
• Handheld terminals and mobile devices
• Battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature grade and 'CKA' denotes the SOT-23-8 package variant. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices or lifecycle changes prior to procurement planning.

Selection Notes

Select this component when a compact footprint is required for RS-232 connectivity. Ensure the design accommodates the 5 V supply constraint. Verify that the 460 kbps speed meets application requirements. Consider the SOT-23-8 thermal characteristics during PCB layout.
