ADM3312EACPZ

Drivers, Receivers, Transceivers Overview

The ADM3312EACPZ is a low-power RS-232 transceiver from Analog Devices, designed for single-supply operation between 2.7 V and 3.6 V. It integrates three drivers and three receivers with full duplex capability and supports data rates up to 460 kb/s. The device features Green Idle power-saving mode and a shutdown function that reduces supply current to 1 µA while keeping one receiver active. It includes an internal charge pump requiring only external capacitors ranging from 0.1 µF to 1 µF. ESD protection exceeds 15 kV on RS-232 I/Os, and it operates within a temperature range of -40°C to +85°C in a 32-lead LFCSP package.

Drivers, Receivers, Transceivers Feature Summary

• Green Idle power-saving mode minimizes consumption by gating the charge pump oscillator under varying load conditions.
• Shutdown facility reduces power consumption significantly while maintaining one active receiver for peripheral monitoring.
• Integrated voltage tripler and inverter generate required RS-232 levels from a single 3 V supply without dual rails.
• High-level electrostatic discharge protection ensures reliability in harsh electrical environments.

Drivers, Receivers, Transceivers Applications

• Serial port applications for PDAs and hand-held devices
• Mobile phone data cables
• Portable computing equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions respect humidity sensitivity levels to prevent moisture-induced damage during soldering processes.

Drivers, Receivers, Transceivers Selection Notes

Select this model when three transmit and receive channels are required for RS-232 communication. It is suitable for battery-powered portable devices due to its low quiescent current and Green Idle functionality. Verify that the application environment requires 15 kV ESD protection on serial lines.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ADM33xxE family of serial port transceivers manufactured by Analog Devices. It shares architectural similarities with the ADM3307E, ADM3310E, ADM3311E, and ADM3315E, differing primarily in driver and receiver counts. The ADM3312E specifically provides a balanced 3x3 configuration for standard serial interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3315EACPZ offers identical pinout and functionality but features higher receiver input resistance (22 kΩ) for reduced drive requirements.

Drivers, Receivers, Transceivers FAQ

How many receivers remain active during shutdown mode?

One receiver remains active during shutdown mode, allowing the device to monitor peripheral communications.

What is the typical shutdown supply current?

The shutdown supply current is typically 1 µA maximum.

Does the device require dual power supplies?

No, it operates from a single 2.7 V to 3.6 V supply using an internal charge pump to generate negative voltages.
