ADM3232EARNZ

Drivers, Receivers, Transceivers Overview

The ADM3232EARNZ is a high-speed, dual-channel RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3 V power supply with a range of 3.0 V to 5.5 V and consumes a typical quiescent current of 3 mA. The device supports data rates up to 460 kbps and includes two drivers and two receivers for full-duplex communication. It features ±15 kV ESD protection on RS-232 I/O pins, meeting IEC 1000-4-2 standards. The component utilizes four external 0.1 μF charge pump capacitors to generate internal voltage levels. It is housed in a 16-lead narrow SOIC package (R-16) and functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15 kV ESD protection on all RS-232 input and output pins ensures robustness against electrostatic discharge events.
• CMOS technology enables low power consumption, making the device suitable for battery-powered portable instruments.
• Internal charge pump circuitry generates required voltage levels using only four small external capacitors.
• Schmitt trigger receivers provide noise immunity and handle slow transition times effectively.

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Portable instruments requiring low power operation
• Industrial and telecom diagnostic ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. The base model ADM3232EARNZ indicates a 16-lead narrow SOIC package. Ensure the procurement order matches the required tape and reel quantity if mass production is intended. Confirm RoHS compliance status as indicated by the 'NZ' suffix in the part number before finalizing purchase orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required with high ESD tolerance. It is appropriate for designs operating strictly from a 3.3 V supply rail. Consider the 16-lead SOIC footprint for PCB layout constraints. Verify that the application environment falls within the specified -40°C to +85°C industrial temperature range for reliable performance.

Drivers, Receivers, Transceivers Part Context

The ADM3232E belongs to the ADM3232E series of RS-232 transceivers from Analog Devices. This series offers variations in packaging options, including TSSOP and wide SOIC formats. The core electrical specifications remain consistent across the family, focusing on low power and high-speed data transmission capabilities for standard serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3232EARUZ serves as a pin-compatible alternative in a TSSOP package. ADM3232EARWZ provides the same functionality in a wide SOIC package. These parts share identical electrical characteristics and can be used where package form factor differences are acceptable.
