ADM3202ARNZ-REEL7

Drivers, Receivers, Transceivers Overview

The ADM3202ARNZ-REEL7 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 supports data rates up to 460 kbps while meeting EIA-232E specifications. The device utilizes four external 0.1 μF capacitors for its internal charge pump voltage doubler and inverter. It features Schmitt-trigger inputs with 0.4 V hysteresis and includes ±8 kV contact discharge and ±15 kV air gap ESD protection on RS-232 pins. The component is housed in a 16-lead Standard Small Outline Package (SOIC_N) and functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates CMOS technology for minimal power dissipation suitable for battery-powered applications
• Provides high slew rate control to minimize electromagnetic interference during transmission
• Includes internal 5 kΩ pull-down resistors on receiver inputs to ensure defined logic states

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Portable instruments and handheld devices
• Printers and personal digital assistants

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix REEL7 confirms tape-and-reel packaging rather than tube distribution. Confirm the 'A' grade designation aligns with the required -40°C to +85°C industrial operating temperature range. Ensure the Z suffix indicates RoHS compliance if environmental regulations apply to the assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required at 3.3 V without shutdown functionality. The ADM3202 lacks the enable and shutdown pins found in the ADM3222 variant. Verify that the 16-lead SOIC package fits the available board space compared to the TSSOP or PDIP options.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM3202/ADM3222/ADM1385 family of line drivers and receivers. It serves as a direct upgrade for legacy MAX3222/MAX3232 and LTC1385 components. The ADM3202 differs from the ADM3222 by omitting the EN and SD control pins, offering a simpler interface for constant-operation designs.

Drivers, Receivers, Transceivers Replacement Considerations

The ADM3202ARNZ is a pin-compatible replacement for the MAX3222 and MAX3232. Designers should verify that the absence of shutdown controls in the ADM3202 meets the system's power management requirements.
