ADM3222ARWZ-REEL

Drivers, Receivers, Transceivers Overview

The ADM3222ARWZ-REEL is a low-power, dual-channel RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3 V power supply and meets EIA-232E specifications with data rates up to 460 kbps. The device features an internal charge pump requiring four 0.1 μF capacitors for voltage conversion. Key functional pins include EN for receiver three-stating and SD for shutdown control, reducing quiescent current to less than 0.5 μA. It is housed in an 18-lead Standard Small Outline Package Wide Body (RW-18) and supports an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated shutdown control reduces power consumption for battery-operated applications
• Internal charge pump enables operation from a single 3.3 V supply without external negative voltage generation
• Receiver enable pin allows three-stating of outputs for bus management

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Portable instruments
• Printers and palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the RW-18 specification when sourcing replacements. Confirm that the specific ordering suffix corresponds to the reel packaging format required for automated assembly processes. Ensure the component version aligns with the Rev. E datasheet requirements for optimal performance.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a dedicated shutdown feature is required to minimize standby power in portable devices. The ADM3222 differs from the ADM3202 by including the EN and SD control pins. Verify that the system design accommodates the 18-pin wide body footprint and provides adequate thermal dissipation within the specified operating temperature range.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ADM3202/ADM3222/ADM1385 family of high-speed RS-232/V.28 interface devices. These parts serve as upgrades for legacy MAX3222/MAX3232 and LTC1385 designs. The family shares common electrical characteristics but varies in pin configurations and control logic availability across different package options.
