At 120 kbps, this transceiver is fast enough for standard RS-232 communication at 9600, 19200, or 115200 baud — the typical speeds for terminal interfaces, PLCs, and barcode scanners. It will not support higher-speed protocols like RS-422 at multi-megabit rates, so if your link needs to push past 1 Mbps, you are looking at a different transceiver family. The 500 mV receiver hysteresis cleans up noisy lines, which helps in industrial environments where cable runs pick up interference.","metaTitle":"MAX232NSR RS-232 Transceiver, 120 kbps, 16-SOIC, Active","metaDescription":"TI MAX232NSR RS-232 transceiver, 2/2 drivers/receivers, 120 kbps, 5V supply, 0-70°C, 16-SOIC.

It is functionally identical to the MAX232N in terms of drivers, receivers, data rate, and supply voltage, but the MAX232N comes in a DIP package. If your board uses a 16-SOIC footprint, the MAX232NSR is a drop-in replacement; if you need a DIP, you would use the MAX232N instead."},{"question":"Does MAX232NSR require external capacitors?","answer":"Yes, like all MAX232-family transceivers, the MAX232NSR requires external charge-pump capacitors (typically four 1 µF capacitors) to generate the RS-232 voltage levels. The exact values and configuration are specified in the datasheet application circuit."},{"question":"What is the maximum data rate of MAX232NSR?","answer":"The MAX232NSR is rated for a maximum data rate of 120 kbps, which covers standard RS-232 baud rates up to 115200 baud."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX232NSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX232NSR when reusing this data.
