MAX3386ECDW

Overview

The MAX3386ECDW is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex communication. It integrates three drivers and two receivers within a single package. The device operates on a supply voltage ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. It achieves data rates up to 250 kb/s with a propagation delay of 0.15 µs. Key electrical characteristics include a quiescent current of 1 mA and 15 kV ESD protection on all pins. The component is housed in a 20-pin SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates three independent drivers and two receivers for comprehensive serial communication capabilities.
• Provides robust electrostatic discharge protection rated at 15 kV across all signal pins.
• Features a dedicated shutdown mode to minimize power consumption during idle periods.

Applications

• Industrial control systems requiring reliable serial data transmission.
• Portable equipment utilizing battery-powered 3V or 5V logic interfaces.
• Embedded devices needing high ESD immunity for harsh environments.

Procurement Notes

Verify the specific suffix 'CDW' against the manufacturer's latest documentation to confirm pinout compatibility and material composition. Check for obsolescence notices as this component may be subject to discontinuation. Ensure that the 20-pin SOIC footprint matches the target PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a combination of three drivers and two receivers is required in a compact form factor. It is suitable for applications demanding low standby current and high noise immunity. Compare performance metrics such as propagation delay and ESD ratings against alternative transceivers to ensure system-level compatibility.

Part Context

This part belongs to the MAX3386E series of RS-232 transceivers. It shares functional similarities with other members like the MAX3386ECDWR and TRS3386E series, which offer comparable driver/receiver counts and power specifications. The primary distinction lies in the packaging type and specific thermal or mechanical characteristics defined by the suffix.

Replacement Considerations

The TRS3386EIDW is identified as a parameter-equivalent replacement option. Verify pin-to-pin compatibility and electrical specifications before substitution. Other family members such as the MAX3386ECDWR may serve as alternatives depending on packaging requirements.
