ADM213ARSZ

Overview

The ADM213ARSZ is a CMOS RS-232 transceiver manufactured by Analog Devices, housed in a 28-lead SSOP package. It operates from a single +5 V supply and includes internal charge pumps to generate ±10 V for RS-232 signaling. The device features four drivers and five receivers with a data rate of 120 kB/s. It supports low power shutdown mode consuming less than 5 μW and maintains two active receivers during shutdown for ring indicator monitoring. Operating temperature range is -40°C to +85°C.

Feature Summary

• Integrates on-board DC-to-DC converters for single-supply operation
• Features low power shutdown mode for battery-powered applications
• Maintains two receiver outputs active during shutdown state
• Includes Schmitt-trigger inputs for noise immunity

Applications

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify the component matches the specific ordering code ADM213ARSZ to ensure correct package type and RoHS compliance status. Confirm that the active high enable pin logic aligns with system design requirements, as this differs from other variants in the family. Check datasheet revision history for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select the ADM213ARSZ when a single +5 V supply is available but ±12 V rails are not. This part is suitable for designs requiring two receivers to remain functional while the rest of the chip is powered down. Ensure external capacitors between 0.1 μF and 10 μF are used for the charge pump circuit. Verify that the 120 kB/s data rate meets the application's transmission speed requirements.

Part Context

The ADM213ARSZ belongs to the ADM2xx family of line drivers and receivers designed for EIA-232-E and V.28 interfaces. It serves as a direct upgrade to older MAX206-211/213 devices. The 'ARSZ' suffix indicates a 28-lead Shrink Small Outline Package (SSOP) variant that is lead-free and RoHS compliant, intended for surface-mount assembly in industrial environments.

Replacement Considerations

The ADM213ARZ is a pin-compatible alternative in a SOIC package. Other ADM2xx family members like the ADM211 offer similar functionality but lack the two active receivers during shutdown. Verify pinout compatibility and control signal polarity differences when substituting.
