Overview
The MAX3386ECPWR is a low-power RS-232 transceiver manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It features three drivers and two receivers, supporting full-duplex communication at data rates up to 250 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It includes a shutdown mode for extended battery life and provides 15 kV ESD protection on all pins. The component functions within an ambient temperature range of 0°C to +70°C.
Feature Summary
- Integrates three independent drivers and two receivers for multi-port serial communication.
- Provides robust electrostatic discharge protection rated at 15 kV across all signal lines.
- Features a dedicated shutdown pin to minimize power consumption during idle periods.
Applications
- Industrial control systems requiring reliable serial data transmission.
- Portable instrumentation powered by single-cell lithium or alkaline batteries.
- Communication modules in embedded systems needing multiple RS-232 ports.
Procurement Notes
Verify the specific suffix 'E' confirms the industrial-grade temperature range and 'C' indicates the plastic TSSOP package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the source document explicitly lists this part number to avoid confusion with similar TRS series equivalents.
Selection Notes
Select this component when three transmit channels are required alongside two receive channels in a compact surface-mount footprint. Compare against the TRS3386EIPWR if an extended temperature range of -40°C to +85°C is necessary for the application environment. Verify that the 250 kb/s speed meets the system's timing requirements.
Part Context
This device belongs to the MAX3386 family of low-power RS-232 transceivers designed for battery-operated equipment. It serves as a direct replacement for older MAX3232-based designs where additional driver channels are needed without increasing board space significantly.
Replacement Considerations
The TRS3386EIPWR is a parameter-equivalent alternative offering an extended temperature range. Verify pin compatibility and electrical specifications before substitution.
