Overview
The MAX3221EAE+TG1Z is a single-driver, single-receiver RS-232 transceiver in a 16-pin SSOP package. 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 supports data rates up to 235kbps with typical propagation delays of 0.3µs. Internal dual charge pumps generate ±5.5V rails using only four 0.1µF external capacitors. The INVALID output indicates shutdown status.
Feature Summary
- AutoShutdown technology reduces power consumption by disabling internal power supplies and drivers during periods of inactivity.
- Integrated dual charge pump eliminates the need for external ±12V power sources.
- INVALID pin provides an active indication of receiver input validity and system power state.
Applications
- Battery-powered equipment requiring low standby current
- Portable diagnostic instruments
- Hand-held communication peripherals
Procurement Notes
Verify the specific suffix TG1Z against manufacturer documentation to confirm reel packaging and lot traceability requirements. Confirm that the E grade (-40°C to +85°C) meets environmental specifications. Ensure the 16-SSOP footprint matches the design layout before procurement.
Selection Notes
Select this component for applications requiring minimal quiescent current without software intervention. Verify that the 16-pin SSOP package fits the board constraints. Ensure the application logic can tolerate the 30µs delay before the transmitters re-enable upon signal detection.
Part Context
This part belongs to the MAX3221 family of low-power RS-232 transceivers. It serves as the single-channel variant within a series that includes two-channel (MAX3223) and five-channel (MAX3243) options sharing identical electrical characteristics and AutoShutdown functionality.
Replacement Considerations
Public confirmed substitutes include MAX3221CAE+ and MAX3221EEAE+. Verify that replacement parts maintain the same 16-SSOP package and temperature range compatibility.
