Product details

RS232 transceiver for 5 V serial links

The Texas Instruments MAX232ECD is a full-duplex RS232 transceiver in a 16-SOIC package, integrating two drivers and two receivers to handle the voltage-level translation between a 5 V UART and RS-232 signal levels. The receiver hysteresis of 500 mV provides noise immunity on the incoming RS-232 lines, reducing the risk of false triggering on a noisy bus.

It is not specified for industrial or automotive environments — if the design sees -40°C or +85°C, look at the industrial-temperature variants in the MAX232 family.

It is ROHS3 compliant.

Frequently asked questions

What is the difference between MAX232ECD and MAX232E?

The MAX232ECD is the specific ordering code for the 16-SOIC package variant of the MAX232E. The MAX232E base part number covers multiple package options; the 'D' suffix in MAX232ECD denotes the 16-SOIC package. Functionally, both share the same transceiver core with 2/2 drivers/receivers and 250 kbps data rate.
