ADM3315EARU

Drivers, Receivers, Transceivers Overview

The ADM3315EARU is a single-supply RS-232 transceiver from Analog Devices, operating within a 2.7 V to 3.6 V range. It integrates three drivers and three receivers with a maximum data rate of 460 kb/s. The device features Green Idle technology for low power consumption, achieving a shutdown supply current of 850 nA. It includes an internal charge pump generating ±6.5 V nominal supplies and provides ESD protection exceeding 15 kV on RS-232 I/Os. The component utilizes a 24-lead TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Green Idle power-saving mode reduces active current drain by gating the charge pump oscillator under varying load conditions.
• Single 2.7 V to 3.6 V power supply operation eliminates the need for external dual voltage rails.
• Integrated charge pump generates required positive and negative voltages using small external capacitors.
• High electrostatic discharge immunity protects RS-232 lines against harsh electrical environments.

Drivers, Receivers, Transceivers Applications

• PDAs and Hand-Held Devices
• Palmtop Computers
• Mobile phone data cables

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and automotive qualification requirements prior to procurement. Ensure the selected variant matches the required pin configuration and thermal characteristics for the target PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a low-current RS-232 interface is required for battery-powered portable electronics. The ADM3315E variant offers reduced receiver input resistance compared to standard models, lowering drive requirements. Verify that the application environment does not require the additional driver/receiver counts found in other family members like the ADM3310E or ADM3311E.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM33xxE line of serial port transceivers designed for full EIA-232 compliance. It shares architectural similarities with the ADM3312E but incorporates specific optimizations for lower current consumption. The series targets applications requiring robust communication interfaces in space-constrained, low-power mobile devices.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3312EARUZ serves as a functional equivalent with identical pinout and driver/receiver counts but lacks the specific 22 kΩ receiver input resistance optimization of the ADM3315E.
