Overview
The MAX3318IPWR is a low-power, full-duplex RS-232 transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.25 V to 3 V, with a typical operating voltage of 2.5 V. The device supports data rates up to 460 kb/s and features two drivers and two receivers. It consumes only 2 mA of supply current during operation. The component includes a shutdown mode for power conservation and provides ESD protection rated at 15 kV. It is housed in a 20-pin TSSOP package and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Integrated IEC 61000-4-2 electrostatic discharge (ESD) protection capability
- Low quiescent current consumption with dedicated shutdown control
- Full-duplex signal transmission supporting standard RS-232 protocols
Applications
- Portable battery-powered equipment requiring low-voltage serial communication
- Industrial control systems utilizing RS-232 interfaces
- Handheld terminals and mobile computing devices
Procurement Notes
Verify the specific suffix IPWR indicates the TSSOP-20 package and reel/cut-tape packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the required temperature grade and package variant for your design implementation.
Selection Notes
Select this component when a 2.5 V supply rail is available and full-duplex RS-232 connectivity is required. The integrated ESD protection reduces external component needs. Verify that the 460 kb/s speed meets application requirements and that the TSSOP-20 footprint fits the PCB layout constraints.
Part Context
This device belongs to the MAX3318 family of low-power RS-232 transceivers. It shares functional similarities with other members like the MAX3318IDBR but differs in package type and operational temperature range specifications. The IPWR suffix specifically denotes the plastic TSSOP package form factor used in surface-mount assemblies.
Replacement Considerations
The TRS3318EIPWR is a documented parameter-equivalent alternative offering identical electrical characteristics and pinout compatibility within the same 20-TSSOP package.
