The 400 mV receiver hysteresis helps reject noise on longer runs. ## Active lifecycle — no LTB pressure for production runs That means no last-time-buy scramble and no forced requalification for existing designs. For new builds, it qualifies as a standard-shelf part through independent distribution, quoted to order against an RFQ. ## Commercial temperature grade — indoor and office equipment only Rated 0°C to 70°C, this transceiver is specified for commercial environments: desktop peripherals, point-of-sale terminals, telecom rack equipment in climate-controlled rooms, and test equipment.","metaTitle":"LT1138ACG#PBF RS232 Transceiver, 250KBd, 5/3 Drivers","metaDescription":"LT1138ACG#PBF is an Analog Devices RS232 full-duplex transceiver with 5 drivers and 3 receivers, 250KBd data rate, 400 mV hysteresis, 4.5-5.5V supply, 0-70°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Bulk","Protocol":"RS232","Data Rate":"250KBd","Mounting Type":"Surface Mount","Package / Case":"28-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Receiver Hysteresis":"400 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"28-SSOP","Number of Drivers/Receivers":"5/3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.77","stockQuantity":0,"priceTiers":[{"qty":35,"price":"$8.77000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/g7ast9fzfc/LITCS09151-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of LT1138ACG#PBF?","answer":"The LT1138ACG#PBF is rated for 250 KBd, which covers standard RS232 rates up to 115.2 kbps with margin for 250 kbps links."},{"question":"What is the closest functional second-source for LT1138ACG#PBF?","answer":"The ADM202JRWZ-REEL is a functional RS232 transceiver but offers only 2 drivers and 2 receivers versus the LT1138ACG#PBF's 5/3 configuration.
