Overview
The ADM236LJN is a single-supply CMOS RS-232 transceiver from the ADM2xxL family, designed for EIA-232-E and V.28 interfaces without requiring ±12 V rails. It integrates two internal charge pumps to generate ±10 V supplies from a single +5 V input using four 1 µF capacitors. The device provides four drivers and three receivers with a 120 kbps data rate and ±9 V output swing. It features a low-power shutdown mode reducing dissipation to less than 5 µW and includes an enable pin for receiver control. The J suffix indicates a commercial temperature range of 0°C to 70°C in a 24-pin PDIP package.
Feature Summary
- Integrates on-board DC-to-DC converters to operate from a single 5 V supply
- Features low power shutdown mode for battery-powered applications
- Includes enable function for connecting to microprocessor data buses
- Provides Schmitt trigger inputs for noise immunity
Applications
- Computers
- Peripherals
- Modems
- Printers
- Instruments
Procurement Notes
Verify the ordering suffix matches the required package type and temperature grade. Confirm that the 'J' designation corresponds to the commercial operating range. Ensure the component meets specific environmental compliance requirements if applicable to the target system design.
Selection Notes
Select this part when a single 5 V supply is available but RS-232 levels are needed. It is suitable for systems requiring shutdown capability to minimize standby power. Verify that the number of drivers and receivers meets interface requirements. Consider the 24-pin package size relative to available PCB space.
Part Context
The ADM236LJN belongs to the ADM2xxL enhanced family, offering lower power consumption and faster slew rates compared to the legacy AD2xx series. It serves as a direct upgrade for applications previously using parts like the MAX223 or AD236, providing improved performance with smaller external capacitors.
Replacement Considerations
Public confirmed substitute part numbers include ADM236LAN and ADM236LCZ. These variants offer the same electrical functionality but differ in package style or temperature rating.
