At 500 kbps, the device supports standard RS-232 baud rates up to 115200 with margin; the actual throughput limit is set by the cable capacitance and driver slew rate, not the IC. ## Active production — no obsolescence pressure The 20-TSSOP package is a standard footprint shared across the TRS3222E family, simplifying second-sourcing or alternate TI variants if supply tightens. ## Package and board integration Surface-mount 20-TSSOP (4.40 mm body width) — the 0.65 mm pin pitch routes cleanly on a two-layer board; the exposed pad is not present, so no thermal-via planning needed.","metaTitle":"TRS3222EIPWR RS-232 Transceiver, 2/2 Full Duplex, 500 kbps","metaDescription":"Texas Instruments TRS3222EIPWR RS-232 transceiver: 2 drivers/2 receivers, full duplex, 500 kbps, 3V-5.5V supply, -40°C to 85°C, 20-TSSOP.","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":"500kbps","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Receiver Hysteresis":"300 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-TSSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.37000","currency":"USD"},{"qty":10,"price":"$2.13200","currency":"USD"},{"qty":25,"price":"$2.01120","currency":"USD"},{"qty":100,"price":"$1.71370","currency":"USD"},{"qty":250,"price":"$1.60908","currency":"USD"},{"qty":500,"price":"$1.40794","currency":"USD"},{"qty":1000,"price":"$1.16658","currency":"USD"},{"qty":2000,"price":"$1.13850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b19bf689625cbb25ca55e900bc6897d0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TRS3222EIPWR?","answer":"Within the TI TRS3222E family, the TRS3222EIPW (tube) and TRS3222EIPWR (tape/reel) share the same die and 20-TSSOP footprint.
