ADM206AN

Overview

The ADM206AN is a CMOS RS-232 transceiver designed for EIA-232-E and V.28 interfaces, operating from a single +5 V supply. It integrates four drivers and three receivers with full-duplex communication capability. The device supports data rates up to 120 kB/s and features an internal charge pump generating ±9 V output swing. Power consumption is 15 mW in normal operation, reducing to less than 5 μW in shutdown mode. It includes TTL/CMOS-compatible inputs with internal pull-ups and Schmitt-trigger receivers with 0.65 V hysteresis. The component operates within a temperature range of -40°C to +85°C and utilizes a 24-lead PDIP package.

Feature Summary

• Integrates onboard DC-to-DC converters to generate required voltage levels from a single power source
• Features low power shutdown mode to minimize energy consumption in battery-powered applications
• Includes enable function allowing receiver outputs to enter high impedance state for bus sharing
• Provides latch-up free construction with robust input protection against overvoltages

Applications

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The 'AN' designation indicates a 24-lead Plastic Dual In-Line Package (PDIP). Confirm RoHS compliance requirements by checking for the 'Z' suffix if lead-free components are mandatory for the assembly process. Ensure the industrial temperature grade matches environmental specifications.

Selection Notes

Select this component when four drivers and three receivers are required for RS-232 communication. The integrated shutdown control allows for power management in portable systems. Verify that the load capacitance does not exceed 2500 pF to maintain specified slew rates. Consider the enable pin functionality if connecting to microprocessor data buses or sharing common lines.

Part Context

The ADM206AN belongs to the ADM2xx family of line drivers and receivers developed by Analog Devices. This series addresses interface challenges where dual voltage supplies are unavailable. The part serves as a direct replacement for legacy MAX206 devices, maintaining pin compatibility while offering enhanced performance characteristics suitable for modern digital communication standards.

Replacement Considerations

The ADM206AN is pin compatible with the MAX206, MAX207, MAX208, MAX211, and MAX213 families. Designers replacing these parts should verify that the substitute component meets the same electrical specifications and package dimensions to ensure mechanical fit and functional equivalence.
