DS232AE+

Drivers, Receivers, Transceivers Overview

The DS232AE+ is a dual RS-232 driver and receiver transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin TSSOP package. It operates from a single +5V power supply (4.5V to 5.5V) with an operating current of 10mA. The device supports data rates up to 350 kbits/sec and meets EIA-232E and V.28 specifications. It features two drivers and two receivers with internal charge pumps generating ±10V using external 0.1μF capacitors. The industrial temperature range version (-40°C to +85°C) is designated as DS232AE-N.

Drivers, Receivers, Transceivers Feature Summary

• Generates RS-232 voltage levels from a single +5V supply using onboard dual charge pumps
• Provides full duplex communication with two independent drivers and receivers
• Includes input hysteresis for improved noise immunity on receiver channels
• Compatible with TTL and CMOS logic input levels

Drivers, Receivers, Transceivers Applications

• EIA/TIA-232E and V.28/V.24 communications interface applications
• Systems requiring height-restricted PCB layouts due to TSSOP packaging
• Industrial equipment operating within extended temperature ranges

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide. The 'N' suffix indicates the industrial temperature range variant (-40°C to +85°C). Confirm that the required package matches the 20-pin TSSOP form factor. Ensure the application design accounts for the necessary external charge pump capacitors.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 solution is required in a low-profile surface-mount package. The standard commercial grade covers 0°C to 70°C, while the -N suffix is necessary for environments requiring operation down to -40°C. Verify that the system power supply remains stable between 4.5V and 5.5V during operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the DS232A family of dual RS-232 transceivers. It is functionally compatible with the LT1181A and MAX232A devices. The AE designation specifically identifies the 20-pin Thin Shrink Small Outline Package (TSSOP) variant, distinguishing it from the 16-pin DIP or SOIC options available in the same series.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the LT1181A and MAX232A. These components share functional compatibility but may differ in pinout or package dimensions. Verify mechanical fit and electrical characteristics before substitution.
