MAX232ECNE4

Overview

The MAX232ECNE4 is a dual RS-232 transceiver manufactured by Texas Instruments, designed for TTL/CMOS to RS-232 voltage level conversion. It operates on a single +5V power supply with a range of 4.5V to 5.5V and draws a typical operating current of 10mA. The device features two drivers and two receivers, supporting full-duplex communication at data rates up to 120kb/s. It is housed in a 16-pin PDIP package and functions within an industrial temperature range of -40°C to +85°C. The component includes ESD protection capabilities and does not feature a shutdown mode.

Feature Summary

• Integrates dual drivers and receivers for bidirectional serial communication
• Converts logic levels between TTL/CMOS and RS-232 standards using a single power source
• Provides electrostatic discharge protection for signal integrity

Applications

• Industrial control systems requiring serial connectivity
• Embedded devices interfacing with PC-based monitoring tools
• Battery-powered equipment utilizing single-supply operation

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance against the manufacturer's official documentation. Confirm the PDIP-16 package type matches the target PCB footprint requirements. Ensure the industrial temperature rating aligns with the operational environment specifications before finalizing procurement orders.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or high-reliability mounting. Choose the industrial grade variant (-40°C to +85°C) over commercial grades if the application involves harsh environmental conditions. Verify that the 120kb/s data rate meets the system's throughput requirements compared to higher-speed alternatives.

Part Context

This part belongs to the MAX232 family, which defines the architecture for single-supply RS-232 transceivers. The 'E' designation typically denotes extended temperature ranges, while 'N' specifies the PDIP package style. The 'E4' suffix generally signifies lead-free manufacturing processes compliant with RoHS directives.

Replacement Considerations

MAX232ECN: Identical functional equivalent without the lead-free suffix. MAX232IDR: Surface mount alternative with similar electrical characteristics but different package type.
