The through-hole DIP package suits socketed prototypes, test fixtures, or legacy equipment where surface-mount retrofits are avoided. There is no EOL notice, no last-time-buy deadline. The standard lead time runs through TI's distribution channel; independent distributors also carry inventory for spot needs. At 120 kbps, the MAX232INE4 supports common baud rates up to 115200 with margin. The 500 mV receiver hysteresis ensures a clean logic output even when the cable picks up noise. For designs that need higher throughput — say 250 kbps or 1 Mbps — this part is not the fit; look at the MAX3232 or MAX3222 family for faster slew-rate-limited RS-232 transceivers. The full-duplex capability means simultaneous transmit and receive on each of the two channels, which maps to two independent UART ports.","metaTitle":"MAX232INE4 RS-232 Transceiver, 120 kbps, 2/2 Driver/Receiver","metaDescription":"MAX232INE4 RS-232 transceiver from TI.

Follow the datasheet pin connections: C1+, C1-, C2+, C2-, V+, V-."},{"question":"What is the difference between MAX232INE4 and MAX232E?","answer":"The MAX232E suffix typically denotes an enhanced ESD rating (±15 kV HBM) compared to the standard MAX232. Both share the same 2/2 driver/receiver count, 120 kbps data rate, and 5 V supply. The key difference is package and temperature grade — the MAX232INE4 is specifically the DIP-16 industrial-temp version."},{"question":"Is MAX232INE4 compatible with MAX232CPE?","answer":"Yes — the MAX232CPE is a pin-compatible DIP-16 RS-232 transceiver from the same MAX232 family. Both are 5 V, 2/2 driver/receiver, 120 kbps parts. For extended-temperature designs, the INE4 is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX232INE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX232INE4 when reusing this data.
