--- - Electronic Component Data [Data Needed] | XAIPART
The component identified only as "---" has no verified manufacturer, function, specification set, or package data available in the current web search results as of 2026-08-26. The retrieved distributor and datasheet aggregator pages (Datasheets.com, Datasheets360.com, Datasheet Archive, Alldatasheet.com, Octopart, Datasheet4U) are generic search portals and do not confirm a real electronic component for this MPN. All parameter values are therefore marked [DATA_NEEDED] and must be replaced with the official manufacturer datasheet before the part is used in a production design. An electronic component datasheet is the authoritative engineering document that defines a component's electrical characteristics, absolute maximum ratings, package dimensions, pin assignments, and environmental compliance. In a typical power management, logic, interface, or analog signal chain, the datasheet is the contract between the manufacturer and the design engineer; selecting a component without a verified datasheet is not acceptable for regulatory approval or reliability review. Because no key features, electrical ratings, or process details can be confirmed for "---", no differentiating specifications can be listed. The XAIPART team should replace this placeholder record with verified second-source parameters, package outline, and lifecycle information as soon as the manufacturer product page is located. Typical uses of a genuine component page include sourcing, BOM risk mitigation, cross-reference search, and footprint verification. Until the actual part is identified, design teams should not allocate PCB land pattern, power budget, or compliance documentation. When the datasheet becomes available, the number-one design consideration is to verify absolute maximum ratings, pinout, and package thermal resistance before layout sign-off.

LSF0102-Q1 - 2-Ch Auto Bidirectional Level Translator | TI
The Texas Instruments LSF0102-Q1 is an automotive-qualified, 2-channel auto bidirectional multi-voltage level translator for open-drain and push-pull applications, packaged in an 8-pin VSSOP (DCU). It operates from 0.95 V to 5.5 V on Vref_A and 1.8 V to 5.5 V on Vref_B, enabling bidirectional translation between 0.95 V and 5.5 V without a direction pin. Data inputs are 5-V tolerant. A voltage level translator is a logic IC that converts signal voltage levels between circuits operating at different supply rails, sitting within the broader hierarchy of voltage translators -> logic ICs -> interface semiconductors. The LSF family uses a pass-gate (transmission-gate) architecture with reference rails, distinguishing it from powered translator families such as TXS/TXB that use MOSFET output stages. Key features include up to 100 MHz up translation and greater than 100 MHz down translation with capacitive loads of 30 pF or less; at a 50 pF load the device supports up to 40 MHz in both directions. This bandwidth covers standard automotive interfaces such as I2C, SPI, GPIO, SDIO, UART, and MDIO. AEC-Q100 qualification makes it suitable for automotive environments. The auto-direction architecture requires no direction-control pin, reducing MCU GPIO overhead and eliminating direction-timing errors. Because the LSF core is a passive pass-gate structure, external pull-up resistors set logic levels on open-drain buses; for push-pull signals, the reference rails Vref_A and Vref_B define the translated levels directly. Typical applications include automotive infotainment I2C buses between 1.8 V SoCs and 3.3 V peripherals, SPI connections between low-voltage MCUs and 5 V sensors, and SDIO/GPIO interfaces in body electronics and cluster modules. Design consideration: because the LSF topology needs external pull-up resistors on open-drain nets, size them against total bus capacitance and target rise time; keep capacitive loading at or below 30 pF to exploit the full 100 MHz translation rate.

The fast 1.2 ns propagation delay preserves signal timing in high-speed links up to 100 Mbps. Technically, the LSF0102 uses a pass-gate (transmission-gate) architecture. The reference pins VREF_A and VREF_B set the logic levels on each side, and external pull-up resistors define the high levels of each domain. The device senses data direction automatically, making it transparent to the host system and reducing pin count and firmware complexity compared to directional translators. Typical applications include I2C and SMBus level shifting between 1.8V, 3.3V, and 5V domains, SPI and UART interfaces in mixed-voltage embedded systems, general-purpose GPIO translation, and battery-powered portable devices where the 6 uA quiescent current minimizes standby drain. Design consideration: pull-up resistor values directly trade off maximum data rate against power consumption; use lower resistance (1-2 kilohm) for high-speed push-pull operation and higher resistance (4.7-10 kilohm) for low-power open-drain buses.
