The 250 kbps data rate is the practical ceiling for the classic MAX232 charge-pump architecture. That covers 115200 baud with margin, but if your design needs 460800 baud or 1 Mbps, this part won't close the eye. For standard UART speeds up to 115200 baud, the 250 kbps rating gives enough headroom for cable capacitance and loading. The receiver hysteresis of 500 mV helps reject noise on longer cable runs, which is useful in industrial environments where the RS-232 lines leave the cabinet. ## Package and footprint — 16-TSSOP The 16-TSSOP body (4.40 mm width, 0.173\" pitch) is a common footprint shared with other MAX232 variants in TSSOP. If your board already has a MAX232IPWR or MAX232IDWR, the pad layout is the same. The surface-mount package reflows with a standard lead-free profile. RoHS compliance is standard for the 'G4' suffix — lead-free and compatible with RoHS requirements.","metaTitle":"MAX232EIPWG4 RS-232 Transceiver, 250 kbps, 16-TSSOP","metaDescription":"Texas Instruments MAX232EIPWG4 RS-232 transceiver, 2/2 drivers/receivers, 250 kbps data rate, 4.5V–5.5V supply, -40°C to 85°C, 16-TSSOP.

Pin-compatible alternatives include the MAX232IPWR (TSSOP, commercial temp) and MAX232IDWR (SOIC, industrial temp). The key difference is the temperature grade and package — the EIPWG4 is the TSSOP industrial version. For a drop-in replacement, verify the operating temperature range matches your environment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX232EIPWG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX232EIPWG4 when reusing this data.
