ADM3101EACPZ-250R7

Drivers, Receivers, Transceivers Overview

The ADM3101EACPZ-250R7 is a single-channel RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 3.0 V to 5.5 V power supply and supports data rates up to 460 kbps. The device integrates one transmitter and one receiver within a 12-lead LFCSP package (CP-12-4). It features ±15 kV air gap and ±8 kV contact ESD protection on all I/O pins. Operating temperature range is specified from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump voltage converter enables operation from a single 3.3 V supply using four external capacitors.
• All RS-232 and CMOS input/output pins provide robust electrostatic discharge protection rated at ±15 kV air gap and ±8 kV contact.
• Receiver includes an internal 5 kΩ pull-down resistor and Schmitt trigger input with 0.4 V hysteresis for noise immunity.

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Industrial diagnostics ports
• Telecommunications equipment interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as the datasheet lists both reel and cut tape options for this package type. Confirm RoHS compliance status indicated by the 'Z' suffix in the part number. Ensure the component source provides valid traceability documentation consistent with Analog Devices manufacturing standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel interface is sufficient for systems requiring high-speed transmission up to 460 kbps. The low power consumption makes it suitable for battery-powered portable instruments. Verify that the system logic levels are compatible with the 3.3 V or 5 V operating ranges defined in the specifications table.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM3101E series of RS-232 transceivers. It is functionally identical to the ADM3101EACPZ-REEL but differs in packaging quantity and handling method. The device utilizes CMOS technology to minimize power dissipation while maintaining full EIA/TIA-232E specification compliance.

Drivers, Receivers, Transceivers Replacement Considerations

The LD3101 is documented as a pin-to-pin alternative offering similar ±15 kV ESD protection and 460 kbps data rate capabilities in a QFN12 package.
