ADM202JRNZ-REEL

Overview

The ADM202JRNZ-REEL is a dual-channel RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and utilizes an on-chip charge pump to generate ±10 V output levels using external 0.1 µF capacitors. The device supports transmission rates up to 120 kB and meets TIA/EIA-232-E specifications. It features two drivers and two receivers, with a typical quiescent current of 2.5 mA. The component is housed in a 16-lead SOIC package (R-16) and is rated for commercial operating temperatures ranging from 0°C to +70°C.

Feature Summary

• Integrated charge pump generates RS-232 voltage levels from a single 5 V supply
• On-board dc-to-dc converters eliminate the need for external split supplies
• Receiver inputs withstand continuous overvoltage levels exceeding ±30 V
• Internal pull-up and pull-down resistors manage unused input states

Applications

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify that the ordering suffix matches the required packaging format. The REEL suffix indicates tape and reel packaging suitable for automated assembly processes. Confirm the RoHS compliance status indicated by the Z suffix if environmental regulations apply to the specific manufacturing run. Ensure the temperature grade corresponds to the intended operational environment.

Selection Notes

Select this component when a single 5 V supply is available and RS-232 communication is required. The integrated charge pump reduces external component count compared to older transceivers. Verify that the 120 kB baud rate meets system timing requirements. Check that the 16-lead SOIC package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the ADM202 series of high-speed CMOS RS-232 transceivers. The J suffix denotes the commercial temperature range. The RNZ designation specifies the narrow body SOIC package variant. This series provides a cost-effective solution for serial communication interfaces requiring robust signal integrity and low power consumption.

Replacement Considerations

ADM202JRNZ-REEL7 is confirmed as a functional substitute offering identical electrical characteristics but supplied in cut tape or smaller reel quantities rather than standard reels.
