Product details

Supply, temperature, and compliance — what the ratings mean for the BOM

The MAX232EIN: The 500 mV receiver hysteresis filters noise on the RS-232 line — a 250 mV noise margin below the hysteresis threshold means the receiver does not chatter on a marginally clean bus. Lifecycle status is Active, and the part is RoHS3 compliant — no end-of-life clock ticking, no restricted-substance paperwork for EU-bound equipment.

No stock-holding claim — each order is verified against the lot.

Frequently asked questions

What is the MAX232EIN used for?

The MAX232EIN is an RS-232 transceiver that converts between 5 V logic levels and RS-232 signal levels. It is used in serial communication interfaces for microcontrollers, embedded systems, industrial controllers, and legacy PC serial ports.

What is the closest pin-compatible alternative to the MAX232EIN?

The MAX232EIN is itself a standard pin-compatible variant in the MAX232 family. The base part number MAX232 covers multiple package options; the EIN suffix specifies the 16-DIP (0.300") through-hole package with the industrial temperature range. Any other MAX232 variant in the same 16-DIP footprint from TI or licensed second sources is functionally interchangeable at the pin level, provided the supply voltage and temperature grade match the application.
