For a UART link running 115.2 kbps or 230.4 kbps, this part has margin; for a 1 Mbps application, it does not. ## Supply rails and temperature grade — where this transceiver fits on the board The 350 mV receiver hysteresis filters out noise on long cable runs — a 30-foot RS-232 cable in an electrically noisy environment picks up common-mode transients that a 200 mV hysteresis receiver would toggle on; this part's 350 mV window rejects those edges.","metaTitle":"MAX3322EEUP+T RS-232 Transceiver, 250 kbps, 20-TSSOP","metaDescription":"Analog Devices MAX3322EEUP+T RS-232 transceiver, 2/2 driver/receiver, 250 kbps data rate, 3V–5.5V supply, -40°C to +85°C, 20-TSSOP.

The MAX3322EEUP+T is rated for 250 kbps and 3V–5.5V supply; the MAX3222EEUP+T has a different data rate and supply range. Confirm the BOM's parametric requirements before substituting — the pinout is identical, but the timing and drive strength may not match."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3322EEUPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3322EEUPT when reusing this data.
