Overview
The MAX3226CAE+T is a single-driver, single-receiver RS-232 transceiver from the MAX3224–MAX3227 family. It operates on a +3.0V to +5.5V supply and achieves a typical 1µA supply current via AutoShutdown Plus™ technology. The device guarantees a maximum data rate of 250kbps and utilizes a dual charge pump requiring only four 0.1µF capacitors for operation at 3.3V. It features a READY output indicating charge pump regulation status and includes FORCEON/FORCEOFF inputs for manual shutdown control.
Feature Summary
- AutoShutdown Plus functionality automatically reduces power consumption when communication lines are idle
- Integrated dual charge pump generates required RS-232 voltage levels using minimal external capacitance
- READY signal provides logic-level indication of internal power regulation readiness
- FORCEON and FORCEOFF pins allow manual override of automatic power management states
Applications
- Notebook, subnotebook, and palmtop computers
- Cellular phones and handheld equipment
- Battery-powered peripherals and printers
Procurement Notes
Verify the specific suffix 'CAE' against official documentation to confirm package type (SSOP) and temperature range (Commercial). Confirm RoHS compliance status associated with the '+' designation. Ensure the component matches the exact pinout and electrical specifications required by the target circuit design before procurement.
Selection Notes
Select this component for applications requiring low-power standby modes in battery-operated systems. Choose the MAX3226 variant specifically when only one transmitter and receiver channel are needed. Verify that the 250kbps data rate meets system requirements, as higher-speed variants like the MAX3225 offer 1Mbps capability.
Part Context
This part belongs to the MAX3224–MAX3227 series of 3V-powered EIA/TIA-232 interface devices. These components share common architectural features including AutoShutdown Plus and dual charge pumps. The MAX3226 is distinguished within the family by its single driver/receiver configuration and 250kbps guaranteed data rate specification.
Replacement Considerations
The MAX3224 and MAX3225 are functionally similar but differ in driver count and data rate. The MAX3228 and MAX3229 offer smaller UCSP packaging. For integrated ESD protection, consider the MAX3222E or MAX3232E series.
