--- - 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.

It operates over a supply voltage range of 3V to 18V, making it suitable for a wide variety of battery-powered and industrial applications. The device features four independent NAND gates, each with Schmitt trigger action on both inputs, providing hysteresis for noise immunity and slow input signal conditioning. A Schmitt trigger is a comparator circuit with hysteresis that converts noisy or slowly changing input signals into clean digital outputs. In the CD4093B, each gate switches at different thresholds for positive-going (VP) and negative-going (VN) signals, with the difference (hysteresis) ensuring stable switching and preventing multiple transitions. This makes the CD4093B ideal for interfacing with sensors, switches, and other real-world signals that may have slow edges or noise. Key features of the CD4093BM96G4 include a wide supply voltage range of 3V to 18V, low quiescent current of typically 4µA, and output drive capability of 3.4mA sink and source. The Schmitt trigger inputs provide hysteresis of typically 0.9V at 5V supply, improving noise margin. The device is fully static, allowing operation at any frequency from DC to several MHz, and is pin-compatible with the standard CD4093B family. The CD4093B is fabricated using silicon-gate CMOS technology, which provides low power dissipation and high noise immunity. The Schmitt trigger action is implemented using a feedback network that creates the hysteresis window. This architecture allows the device to operate reliably in noisy environments and to condition signals with slow rise/fall times, such as those from RC oscillators or mechanical switches. Typical applications include waveform shaping, pulse generation, debouncing of mechanical switches, and as an oscillator in RC timing circuits. The CD4093BM96G4 is also used in sensor signal conditioning, where its hysteresis prevents false triggering. Its wide operating voltage range makes it suitable for both 5V and 3.3V logic systems, as well as higher-voltage industrial controls. When designing with the CD4093BM96G4, ensure that input voltages do not exceed the supply rails, and consider adding a series resistor to limit input current if the input may exceed the supply. The Schmitt trigger inputs eliminate the need for external hysteresis components, simplifying circuit design. For high-speed applications, note that propagation delay is typically 80ns at 5V, which is adequate for most control and timing functions.

This decoder sits between a counter or microcontroller and the display, simplifying the interface and reducing the number of I/O pins required. Key features of the CD4511B include lamp test (LT), blanking (BL), and latch enable (LE) inputs. The lamp test input forces all segments on to verify display functionality. The blanking input can shut off the display or be used for intensity modulation via pulse-width modulation. The latch enable input stores the BCD code, allowing multiplexed displays where several digits share the same decoder. The device also features an internal pull-down on the BCD inputs, ensuring a defined logic level when inputs are floating. Technically, the CD4511B is fabricated on a single monolithic structure combining CMOS logic with bipolar output transistors, a process known as BiCMOS. This architecture provides the low power consumption of CMOS with the high current drive capability of bipolar transistors. The outputs are active-high and can source 25 mA, sufficient for driving standard LEDs with appropriate current-limiting resistors. The device operates over a supply voltage range of 3V to 18V, with a typical quiescent current of only 80 µA at 5V, making it suitable for battery-powered applications. Typical applications include digital clocks, frequency counters, digital voltmeters, and any system requiring numeric display. The CD4511B is often used with 7-segment LED displays in instrumentation, consumer electronics, and industrial control panels. Its ability to latch data makes it ideal for multiplexed display systems, reducing the number of decoder ICs needed. When designing with the CD4511B, ensure that the supply voltage is within the specified range and that current-limiting resistors are placed in series with each segment to prevent excessive current. The blanking input can be used for brightness control by applying a PWM signal. For multiplexed displays, the latch enable input should be pulsed after the BCD data is stable to avoid display flicker.

The Texas Instruments CD74ACT163 is a 4-bit synchronous presettable binary counter with synchronous reset, fabricated in the advanced CMOS (ACT) logic family and housed in a 16-pin SOIC package. It operates from a 5V supply with TTL-voltage-compatible inputs, and features an internal carry look-ahead for high-speed counting designs plus a ripple carry output (RCO) for n-bit cascading. A synchronous binary counter is a sequential logic IC in which all flip-flops are clocked simultaneously by a common clock edge, so all output bits change in coincidence rather than rippling stage to stage. Within the logic IC hierarchy (counter -> sequential logic IC -> digital IC), synchronous counters eliminate the cumulative propagation delays of ripple (asynchronous) counters, enabling reliable high-speed counting and glitch-free decoded outputs. Key features include synchronous counting, synchronous parallel load via the active-low LOAD input for programmable counting, and synchronous reset (CLR) that clears all outputs on the next clock edge, eliminating the decoding spikes inherent in asynchronous clearing. The count-enable inputs (ENP, ENT) permit cascading and gated counting without external gating logic, and the RCO terminal supports direct n-bit cascading. The ACT technology combines CMOS low static power with TTL input thresholds at 5V operation, making the device directly interchangeable in TTL 74163 sockets. Positive-edge clocking and fully synchronous preset, count, and clear functions simplify timing analysis in multi-stage counter chains. Typical applications include frequency division, digital timers, event counting, address generation, industrial sequencing, and cascaded n-bit counters built by wiring RCO of one stage to ENT of the next. Design consideration: because reset and load are synchronous, hold CLR or LOAD low for at least one full clock period; for asynchronous-reset designs use the related CD74ACT161 instead. Decouple the 5V rail with 0.1uF close to the VCC pin. This page synthesizes distributor data, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

The silicon-gate CMOS process provides high noise immunity and very low quiescent current compared with bipolar LSTTL equivalents. Architecturally, data present on the D inputs is stored on each rising clock edge, while OE=HIGH forces all Q outputs into a high-impedance state without disturbing the stored register contents. This enables bus multiplexing, shared data buses, and bidirectional data flow in microprocessor and memory systems. The device works in both 3.3V and 5V logic systems thanks to its wide supply range. Typical applications include microprocessor address and data latching, I/O port expansion, bus interfacing, register files, and synchronization stages in DSP and communication interfaces. Designers should keep the clock clean and glitch-free, control OE to avoid bus contention, and place 100 nF decoupling capacitors close to the VCC pin. According to TI datasheet SCHS183A, unused inputs must never be left floating.

The CPGA-84 package provides robust mechanical and thermal performance for harsh-environment systems. Technically, the device uses Altera's classic EEPROM/UV-CMOS MAX architecture with a programmable AND/OR array and dedicated macrocell flip-flops. The 55ns tPD places it in the medium-speed tier suitable for control logic, bus interfacing, and glue logic rather than high-speed datapath applications. The 192 macrocells and high I/O count make it one of the larger classic PLDs of its era. Typical applications include military and aerospace digital control systems, industrial control logic, legacy avionics and radar signal processing interface logic, defense telemetry equipment, and MIL-spec replacement of obsolete 54xx TTL logic arrays. Engineers use it where high reliability, -55C to +125C operation, and high-density PLD logic are required. Design considerations include the UV-erase window requiring a quartz-windowed package for reprogramming, which is slower than EEPROM-based modern PLDs. Designers must budget for the 55ns propagation delay when interfacing to faster buses. Use Altera's MAX+PLUS II development toolchain for design entry, fitting, and programming.

A digital isolator is a semiconductor device that transfers digital signals across an isolation barrier, galvanically separating two ground domains to block high voltages, reject ground loops, and protect low-voltage circuitry. Within the power-signal-chain hierarchy, digital isolators sit under the isolation products family, alongside isolated transceivers and gate drivers, and are foundational components in industrial and automotive power management systems. Key features include the 50 Mbps data rate supporting fast SPI, UART, and general-purpose GPIO traffic, 1.8 V to 5 V logic compatibility on both sides for direct interfacing with modern MCUs, and the 100 kV/us CMTI rating that keeps signals intact in the presence of aggressive switching transients from SiC and IGBT power stages. The AEC-Q100 qualification makes the part suitable for automotive environments. The ISO676x-Q1 family uses TI capacitive isolation technology, with an SiO2-based barrier providing reinforced isolation. The 3/3 channel configuration (three channels in each direction) supports bidirectional buses such as full-duplex SPI (SCLK, MOSI, MISO plus CS) across the barrier without direction-control pins, reducing firmware overhead and glitch risk. The wide-body DW package provides adequate creepage and clearance for reinforced isolation designs. Typical applications include isolated SPI communication in battery management systems (BMS), isolated UART and GPIO in on-board chargers and traction inverters, isolated communication in motor drives, and industrial PLC I/O isolation. Design consideration: verify the total load capacitance on both sides; at 50 Mbps the output drivers need adequate decoupling (100 nF local plus 4.7 uF bulk per side is a common practice) to maintain signal integrity during simultaneous switching of multiple channels.

LM393DR - Dual Differential Comparator SOIC-8 | Texas Instruments
The Texas Instruments LM393DR is a dual differential comparator integrating two independent, high-gain precision comparators on a single monolithic chip in an 8-pin SOIC surface-mount package. It operates from a single supply of 2V to 36V or dual supplies of ±1V to ±18V, with an open-collector output stage that supports rail-to-rail output flexibility. A comparator is an analog component that compares two input voltages and drives its output to indicate which is higher. Within the component hierarchy, the LM393 belongs to the general-purpose comparator family (a cousin of the operational amplifier optimized for fast saturated switching), sitting alongside the LM339 quad and LM2903 automotive variants in the power-management and signal-conditioning landscape. Key features include very low supply current of approximately 0.4 mA per comparator, which does not increase with supply voltage, low input offset voltage (typically 1 mV), and a wide common-mode input range that extends down to ground (V-), enabling ground-sensing applications. The open-collector outputs allow wired-OR configurations and direct interface to logic families via a pull-up resistor to any voltage up to 36V, independent of the comparator supply. The LM393 architecture uses a PNP differential input stage on a proven junction-isolated bipolar process that has made it an industry standard for decades. Multiple manufacturers (TI, ROHM Semiconductor, and others) second-source the identical LM393DR ordering code, offering strong supply-chain resilience and true drop-in interchangeability. The improved LM393B version is a drop-in replacement offering lower offset (0.37 mV), lower bias current, and faster 1 us response time. Typical applications include voltage-level detection, zero-crossing detection, oscillator and square-wave generation, window comparators, battery undervoltage/overvoltage monitors, and limit comparators in industrial and consumer systems. It is a staple in power-supply supervisory circuits and sensor threshold detection, often paired with NE555 timer-based designs. Design consideration: always use a pull-up resistor (typically 1 kOhm to 100 kOhm) on each open-collector output, and add hysteresis (a few mV via positive feedback) to prevent output oscillation from slow-moving input signals near the threshold.
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.
LSF0102DDFR - 2-Ch 100Mbps Level Translator | TI
The Texas Instruments LSF0102DDFR is a dual-channel auto-bidirectional multi-voltage level translator supporting both open-drain and push-pull applications. Housed in an 8-pin TSOT-23-8 (DDF) package, it translates signals between voltage domains from 0.95V up to 5.5V at data rates up to 100 Mbps without requiring a direction control pin. A level translator, or voltage level shifter, is a logic IC that enables digital signals to safely cross between circuits operating at different supply voltages, such as 1.8V, 3.3V, and 5V domains. Within the hierarchy of logic ICs, translators sit alongside buffers and bus switches in the signal-interface layer of a system, ensuring reliable communication in mixed-voltage designs. Key features include fully automatic bidirectional translation with no direction pin, support for open-drain buses (I2C, SMBus) and push-pull interfaces (SPI, UART), a wide 0.95V to 5V translation range, and ultra-low quiescent current of 6 uA typical. The fast 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.

The device supports a ±15V analog signal range and provides overvoltage protection without channel interaction, making it suitable for harsh industrial environments. CMOS fabrication ensures low power consumption and high input impedance. Fabricated in CMOS technology, the MPC506 provides low leakage currents and high input impedance, preserving signal integrity. The internal 1kOhm series resistance protects the device from overvoltage conditions up to 70Vpp, eliminating external protection components in many applications. Break-before-make switching ensures the output is never momentarily connected to two inputs simultaneously, preventing signal corruption. Typical applications include data acquisition systems, test and measurement equipment, industrial process control, and medical instrumentation. The MPC506 is ideal for routing multiple analog signals to a single ADC, expanding channel count in a measurement system, or implementing programmable gain amplifier configurations. When designing with the MPC506, ensure analog input signals remain within the specified ±15V range to avoid damage. Drive the digital address lines with proper logic levels, and buffer the output if driving a capacitive load to maintain stability.

The device is qualified to QML-V (MIL-PRF-38535 Appendix V) standards for radiation tolerance, making it appropriate for satellite and deep-space missions. Technically, the device uses a CMOS process providing high noise immunity and low static dissipation. Internal inverters and drivers supply full data selection to the four output gates. When the strobe (G) is high, all outputs are forced low, simplifying bus isolation. Inputs accept standard CMOS levels and are TTL compatible at 5 V operation. Typical applications include data routing in spacecraft telemetry systems, selection between primary and backup data paths in redundant architectures, and switching between instrument outputs in satellite payloads to conserve downlink bandwidth. The -55C to +125C operating range and hermetic ceramic DIP (CDIP-16) packaging support these extreme environments. When designing with this device, decouple VCC close to the pins, drive the strobe input to a known state during power-up, and verify select and data inputs meet setup and hold requirements relative to the system clock, considering the 11 ns typical propagation delay.

It comes in a 14-pin CDIP package, suitable for through-hole mounting in harsh environments. An inverter is a logic gate that outputs the logical complement of its input. The SN54LS05 specifically features open-collector outputs, meaning the output transistor's collector is left unconnected internally, requiring an external pull-up resistor to define the high-level output voltage. This allows the device to interface with different voltage domains and to implement wired-OR logic by connecting multiple outputs together. Open-collector outputs also enable driving loads such as relays, LEDs, and lamps directly, with appropriate current limiting. Key features include six independent inverters, a wide operating temperature range of -55°C to 125°C, and compatibility with TTL logic levels. The open-collector outputs can sink up to 8 mA, and the device supports a supply voltage range of 4.5 V to 5.5 V.

It is available in a 56-pin SSOP package (DL suffix) and a 56-pin TSSOP package (DLR suffix). A bus-interface D-type latch is a digital logic component that captures data on its D inputs when the latch enable (LE) signal is asserted, holding the data on its Q outputs until the next enable pulse. It is a fundamental building block in digital systems for temporary data storage, bus isolation, and signal synchronization. In the hierarchy of digital logic, it belongs to the category of latches, which are level-sensitive storage elements, as opposed to edge-triggered flip-flops. Latches are essential in microprocessor systems, memory interfaces, and data acquisition circuits where multiple data lines must be captured simultaneously. Key features of the SN74ABT162841 include 3-state outputs that allow connection to a shared bus without contention, a flow-through architecture that simplifies PCB layout, and distributed VCC and GND pins that minimize high-speed switching noise.

The EPIC-B BiCMOS design significantly reduces power dissipation compared to bipolar logic, making it suitable for high-density systems. Technically, the SN74ABT162841 uses a BiCMOS process that combines the speed of bipolar transistors with the low power of CMOS. The outputs have equivalent 25-ohm series resistors, eliminating the need for external resistors in many applications. The device is characterized for operation from -40°C to 85°C, and it is RoHS compliant. The 3-state outputs are controlled by an output enable (OE) input, which places the outputs in a high-impedance state when asserted high, allowing multiple devices to share a bus. Typical applications include memory address latching, data bus buffering in microprocessor systems, and interface circuits for industrial control and telecommunications equipment. The wide operating voltage range and high drive capability make it ideal for 5V systems that require robust signal integrity. The flow-through pinout aligns inputs and outputs on opposite sides, simplifying board routing and reducing crosstalk. When designing with this device, ensure that the OE and LE inputs are properly driven to avoid bus contention. The 3-state outputs allow multiple latches to share a bus, but only one should be enabled at a time. Consider the propagation delay and setup/hold times when designing timing margins for high-speed applications.

This allows the latch to drive bus lines directly, reducing the need for external buffers. The device also features a latch-enable (LE) input that is level-sensitive, making it transparent when high and latched when low. Typical applications include address latching in microprocessor systems, data buffering in memory interfaces, and general-purpose I/O expansion. The high drive capability and 3-state outputs make it ideal for bus-oriented designs where multiple peripherals share a common data bus. The wide operating temperature range of -40°C to 125°C (Enhanced Product) ensures reliable operation in industrial and automotive environments. When designing with this device, ensure that the OE and LE inputs are properly driven to avoid bus contention. The high-impedance state should be used to prevent multiple outputs from driving the same bus simultaneously. Additionally, consider the propagation delay and setup/hold times to meet system timing requirements.
