MAX3221CAE+TG077

Overview

The MAX3221CAE+TG077 is a single-driver, single-receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +3.0V to +5.5V supply and achieves 1µA supply current via the AutoShutdown feature when no valid signal is detected on receiver inputs for 30µs. The device utilizes a proprietary dual charge-pump power supply to generate ±5.5V internally, eliminating the need for external ±12V supplies. It supports data rates up to 235kbps with typical operation at 120kbps under worst-case loads. The component is housed in a 16-pin SSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

AutoShutdown technology reduces supply current to 1µA upon detecting inactive receiver inputs
Integrated dual charge-pump circuitry generates internal ±5.5V rails from a single low-voltage supply
Direct interface compatibility with TTL and CMOS logic families without level shifting

Applications

Battery-powered equipment requiring extended standby life
Hand-held devices and portable diagnostics equipment
Serial communication interfaces in peripherals

Procurement Notes

Verify the specific suffix 'TG077' against official manufacturer documentation to confirm lot traceability or tape-and-reel specifications. Confirm that the ordering code matches the exact pinout and electrical characteristics defined in the MAX3221 datasheet before finalizing procurement orders.

Selection Notes

Select this component for designs requiring minimal quiescent current during idle periods. Ensure the application environment remains within the specified 0°C to +70°C temperature range. Verify that the system power supply voltage stays between +3.0V and +5.5V to maintain proper charge-pump functionality and signal integrity.

Part Context

This part belongs to the MAX3221/MAX3223/MAX3243 family of +3V to +5.5V RS-232 transceivers. The MAX3221 specifically provides one driver and one receiver, distinguishing it from the two-channel MAX3223 and the five-receiver MAX3243. All members share the same core AutoShutdown and charge-pump architecture.
