The receiver hysteresis of 300 mV provides noise immunity on long cable runs. ## Supply range and temperature grade The wide supply range (2.4 V to 5.5 V) allows direct connection to common logic rails without an external regulator. Package is 20-TSSOP (4.40 mm width) with surface-mount footprint. The tape-and-reel option (MAX3381ECUP+T) is the standard ordering code for automated assembly; cut-tape also available for prototyping. ## Lifecycle and sourcing posture ROHS3 compliant. This is a current-production part — no last-time-buy pressure, no allocation risk reported across distribution channels. For BOM planning: the part is widely available through multiple distributor channels. No direct replacement or pin-compatible second source is listed by the manufacturer; the MAX3381E family shares the same base function but verify the package and supply range against your board.","metaTitle":"MAX3381ECUP+T RS-232 Transceiver 250 kbps 20-TSSOP","metaDescription":"MAX3381ECUP+T Analog Devices RS-232 transceiver, full duplex, 2/2 drivers/receivers, 2.4V-5.5V supply, 250 kbps data rate, 20-TSSOP, active production, ROHS3","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.4V ~ 5.5V","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"20-TSSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.40000","currency":"USD"},{"qty":10,"price":"$8.49200","currency":"USD"},{"qty":25,"price":"$8.09680","currency":"USD"},{"qty":100,"price":"$7.03040","currency":"USD"},{"qty":250,"price":"$6.71444","currency":"USD"},{"qty":500,"price":"$6.12200","currency":"USD"},{"qty":1000,"price":"$5.92452","currency":"USD"},{"qty":2500,"price":"$5.92452","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/71eb31354cefc5a986e481bc47187b2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX3381ECUP+T replace MAX3381E?","answer":"The MAX3381E family shares the same RS-232 transceiver function and 2/2 driver/receiver count, but package and supply range may differ.
