ADM238LJNZ

Overview

The ADM238LJNZ is a CMOS RS-232 transceiver from Analog Devices, designed for single 5 V operation. It integrates four drivers and four receivers within a 24-pin WSOIC package. The device meets EIA-232-E specifications with a data rate of 120 kbps and ±9 V output swing. Internal charge pumps generate the required ±10 V supplies using external 1 µF capacitors. It operates in the commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates four drivers and four receivers for full RS-232 communication
• Operates from a single 5 V power supply via internal voltage converters
• Includes Schmitt trigger inputs on receivers for noise immunity
• Features internal pull-up and pull-down resistors on logic inputs

Applications

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify the specific suffix 'JNZ' against official documentation to confirm pinout compatibility and environmental ratings. Confirm that the component matches the standard ADM238L electrical specifications before integration into designs requiring strict interface compliance.

Selection Notes

Select this part when four independent transmit and receive channels are required. Ensure the application environment remains within the 0°C to 70°C commercial operating range. Verify that the system design accommodates the necessary external 1 µF capacitors for the internal charge pump circuitry.

Part Context

This component belongs to the ADM2xxL family of line drivers and receivers. It serves as an enhanced upgrade to the AD2xx series, offering lower power consumption and faster slew rates. The ADM238L specifically provides a balanced configuration of four drivers and four receivers.
