TPS3701DDCT - 36V Dual Window Comparator | Texas Instruments
The Texas Instruments TPS3701DDCT is a dual window voltage detector with two precision comparators, a 400 mV internal reference, and two open-drain outputs rated to 25 V, packaged in a 6-pin SOT-23-THIN configuration. It operates from 1.8 V to 36 V and is designed for overvoltage and undervoltage monitoring. A window comparator is a voltage detector that checks whether an input voltage lies between programmable upper and lower thresholds. Unlike a general-purpose comparator, this device integrates two comparison channels and a reference, allowing one IC to monitor both rail boundaries. In the power-management hierarchy, it belongs to the comparator and voltage-supervisor family rather than a power-regulator family. Key features include the 1.8 V to 36 V supply range, a 400 mV internal reference, two open-drain outputs, and monitoring flexibility through external resistor networks. The open-drain outputs can be pulled up to an appropriate external voltage, allowing wired interface use and flexible system-level signaling. Reported low quiescent current is approximately 7 µA typical, making the device suitable for low-power monitoring systems. The TPS3701 can operate as a window detector or as two independent voltage monitors. The monitored thresholds are established with external resistors, while the internal reference provides the comparison basis. Its high-voltage operating range allows monitoring of industrial supplies and other rails where input transients or nominal voltages exceed the range of simpler low-voltage supervisors. Response time is reported in distributor data as approximately 155 µs. Typical applications include industrial automation, battery systems, power-supply protection, sensor interfaces, and embedded control systems. It is especially useful when a system must assert separate fault signals when a monitored voltage becomes too high or too low. Because the outputs are open-drain, pull-up resistors are required unless the output is connected directly to a compatible pull-up arrangement. Designers should verify the full datasheet pinout, threshold tolerances, timing, output ratings, and capacitor or resistor recommendations before production. The SOT-23-THIN footprint supports compact layouts, but the open-drain pins and monitor-input network require careful routing. For replacements, compare the complete pinout and threshold architecture rather than selecting a part only by supply voltage or package name. This page combines verified manufacturer information, distributor pricing references, and practical design guidance.
TS3A5018QPWRQ1 - 10-Ohm Quad SPDT Analog Switch | Texas Instruments
The Texas Instruments TS3A5018QPWRQ1 is an automotive-qualified (AEC-Q100) quad single-pole double-throw (SPDT) analog switch designed to operate from a 1.8V to 3.6V supply. Packaged in a 16-pin TSSOP (PW), it provides four independent SPDT switches with a low 10-ohm on-resistance, handling both digital and analog signals up to V+ in either direction. An analog switch (also called an analog multiplexer/demultiplexer or bidirectional switch IC) is a semiconductor device that routes analog or digital signals through a MOSFET transmission gate controlled by a digital select input. Analog switches sit within the broader signal-routing hierarchy: analog switch IC -> signal multiplexer -> interface and switching IC -> analog signal chain. They are fundamental building blocks wherever a processor must dynamically reconfigure signal paths without degrading signal integrity. Key features of the TS3A5018QPWRQ1 include the low 10-ohm typical on-resistance, wide 1.8V to 3.6V single-supply operation suited to battery-powered and low-voltage systems, full rail-to-rail signal handling, and break-before-make switching that prevents momentary shorting of signal sources. The Q1 suffix denotes AEC-Q100 qualification for automotive environments, with an extended operating temperature range supporting under-hood and body electronics applications. The device uses CMOS transmission-gate architecture, which keeps on-resistance relatively flat across the signal range and minimizes signal distortion for audio and data-routing tasks. Because signals up to V+ can pass in either direction, the switches work equally well for multiplexing and demultiplexing, such as sharing a codec between microphone and headset paths or switching antenna and test signals. Typical applications include automotive infotainment audio routing, battery-management cell-monitoring multiplexing, portable instrument signal switching, and general-purpose I/O expansion in industrial control boards. Design tip: minimize RON signal loss by keeping source impedance low, and always provide a solid V+ decoupling capacitor (0.1uF close to the pin). Remember that the analog signal range is limited to the 0V-to-V+ supply window; signals outside this range must be blocked or level-shifted.
TS5A3159QDBVRQ1 - 1Ω SPDT Analog Switch AEC-Q100 | TI
The Texas Instruments TS5A3159QDBVRQ1 is an automotive-qualified (AEC-Q100) single-pole double-throw (SPDT) 2:1 analog switch with 1Ω typical ON-state resistance (1.3Ω max), operating from a 1.65V to 5.5V supply in a 6-pin SOT-23 (DBV) package. An analog switch is a semiconductor device that routes or gates analog and digital signals under the control of a logic-level input. Within the signal-chain hierarchy, the SPDT analog switch sits in the analog switches and multiplexers family, below large multiplexer arrays and alongside transmission-gate logic. An SPDT device connects one common (COM) terminal to either of two throw terminals (NO or NC), making it the fundamental building block of signal routing and redundancy switching. Key features include break-before-make switching, which prevents momentary channel shorting during transition and eliminates signal distortion when a signal source moves between paths; an excellent total harmonic distortion (THD) specification that preserves audio and precision-signal integrity; and low ON-resistance matching and flatness, which minimize signal error across the input range. The device operates from a single 1.65V to 5.5V supply, compatible with 1.8V, 2.5V, 3.3V, and 5V logic systems. The switch core uses a low-charge-injection MOS transmission-gate architecture with approximately 8pF typical ON capacitance (per TI family data), limiting high-frequency insertion loss in data and RF routing paths. The digital IN pin is logic compatible across the full supply range, and the -Q1 suffix denotes AEC-Q100 qualification with -40C to +125C operation for automotive environments. Typical applications include automotive audio source selection, sensor-signal multiplexing in battery-management and body-control modules, UART/SPI/SMBus line sharing, and general-purpose signal gating in industrial systems. The 2.9mm x 1.6mm SOT-23-6 footprint suits densely populated boards. Design tip: terminate or AC-ground unused throw terminals to reduce crosstalk, and place the device close to the signal source to minimize parasitic trace capacitance.

TS5A63157 - 10-Ohm SPDT Analog Switch 1.65-5.5V | TI
The Texas Instruments TS5A63157 is a single-pole, double-throw (SPDT) analog switch, also described as a 2:1 multiplexer/demultiplexer, designed to operate from a 1.65 V to 5.5 V supply. It handles both digital and analog signals with a low on-state resistance of approximately 10-12 ohms and comes in a 6-pin SC-70 (SOT, SC70-6, DCK) surface-mount package. An analog switch is a type of signal-routing IC in the broader family of multiplexers and switches within the semiconductor component hierarchy. Unlike a relay or mechanical switch, an analog switch uses CMOS transmission gates to route signals with low distortion, fast switching times, and no moving parts, making it fundamental to signal-chain design in portable and battery-powered systems. Key features include overshoot and undershoot voltage protection: the device senses voltage events at the I/Os and responds by preventing voltage differentials from developing and turning the switch on. It also provides isolation in powered-off mode (leakage specified at 0 when V+ = 0), break-before-make switching, 5-V tolerant control inputs, low charge injection, and excellent on-state resistance flatness. Technically, the TS5A63157 uses a CMOS switch architecture with integrated protection circuitry, allowing it to survive I/O faults that would damage unprotected switches. The powered-off isolation makes it ideal for hot-swap and battery-powered systems where rails may be sequenced or removed while signal lines remain connected. Typical applications include battery-powered portable devices, audio signal routing, hot-swap USB and peripheral switching, and multiplexing sensor or test signals in instrumentation. Priced at roughly $0.34 in single units as of 2026-08-30 per distributor data, it is also cost-effective for high-volume designs. Design tip: ensure the control input logic level is compatible with the V+ rail; control inputs are 5-V tolerant regardless of supply, and the break-before-make timing prevents momentary shorting of the two switch paths during transitions.
TXB0104D - 4-Bit Bidirectional Level Translator, 100Mbps | TI
The Texas Instruments TXB0104D is a 4-bit bidirectional voltage-level translator with automatic direction sensing, delivering up to 100 Mbps data rates in a 14-pin SOIC (D) package, with VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V plus +/-15 kV ESD protection. A voltage-level translator (also called a level shifter) is a logic IC that interfaces digital circuits operating at different supply voltages, allowing a 1.8V microcontroller to safely communicate with a 3.3V or 5V peripheral. Level translators sit within the broader logic IC family, alongside buffers, transceivers, and bus switches, and are a fundamental part of system power-management and signal-chain design wherever mixed-voltage domains coexist. Key features of the TXB0104D include fully automatic direction sensing that eliminates the direction-control pin required by conventional transceivers, universal translation among 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V nodes, and a 100 Mbps maximum data rate that supports fast embedded buses. An active-high OE input tri-states all eight I/Os when low, providing board-level power sequencing isolation. Architecturally, the TXB family uses two separate configurable power-supply rails: port A tracks VCCA and port B tracks VCCB. Internal one-shot circuits sense edges and briefly drive stronger pull-up/pull-down transistors, while a 4 kOhm series switch holds the level in static conditions. This push-pull CMOS design requires neither pull-up resistors nor direction control, but it does mean the TXB0104 is suited to push-pull CMOS outputs only, not open-drain buses unless replaced by the TXS family. Typical applications include MCU-to-peripheral interfacing across mixed voltage domains, SPI and UART signal translation, and general-purpose 1.2V-to-5V logic bridging in industrial and consumer systems. The -40C to +85C operating range covers most commercial and industrial environments. Design consideration: keep VCCA lower than or equal to VCCB, and remember the weak static drive (about 4 kOhm) cannot handle heavy loads, long wires, or pull-up resistors below about 50 kOhm.

TXB0104RUTR - 4-Bit Bidirectional Level Shifter | Texas Instruments
The Texas Instruments TXB0104RUTR is a 4-bit bidirectional voltage-level translator with automatic direction sensing and ±15-kV ESD protection (Human Body Model), housed in a 12-pin UQFN (RUT) package measuring 1.7 mm x 2.0 mm. It translates signals between a low-voltage A port operating from 1.2 V to 3.6 V and a higher-voltage B port from 1.65 V to 5.5 V (VCCA <= VCCB), supporting data rates up to 100 Mbps. A voltage-level translator, also called a level shifter, is an integrated circuit in the logic-translation family that enables communication between digital devices operating at different supply voltages. In mixed-voltage systems, a 1.8 V or 3.3 V MCU may need to interface with 5 V peripherals; translators convert logic levels bidirectionally while protecting low-voltage silicon. The TXB0104 belongs to the auto-direction-sensing translator family, eliminating direction-control pins and simplifying both PCB design and firmware. Key features include per-channel automatic direction sensing, ±15-kV HBM ESD protection on all pins, tri-state outputs with an output-enable (OE) pin for bus isolation, and an operating temperature range of -40C to +85C. Low quiescent current and the tiny UQFN footprint suit space-constrained portable designs. Architecturally, the TXB0104 uses a one-shot edge accelerator that speeds rising and falling edges, enabling 100 Mbps operation with low static power. The A port tracks VCCA and the B port tracks VCCB. Partial power-down via OE and Ioff-style isolation make it suitable for hot-insertion environments. Typical applications include SPI, UART, and push-pull GPIO level shifting between MCUs, sensors, SIM card and SD card interfaces, and memory peripherals in mobile, industrial, and consumer products. The push-pull driver topology is not recommended for open-drain buses such as I2C or 1-Wire, as confirmed in TI E2E forum threads. Design tip: power VCCA before VCCB, place 0.1 uF bypass capacitors close to both supply pins, and use the OE pin for sequencing. For open-drain buses, consider TXS0104E instead.
TXB0104W-Q1 - 4-Bit Auto-Direction Level Translator | Texas Instruments
The Texas Instruments TXB0104W-Q1 is an automotive-grade 4-bit bidirectional voltage-level translator with automatic direction sensing, rated for data rates up to 100 Mbps and protected by +/-15 kV IEC ESD protection on the I/O pins, housed in a 12-pin UQFN (RUT) package. Qualified per AEC-Q100 for automotive applications, the W variant supports a VCCA supply range of 1.1 V to 3.6 V and a VCCB range up to 3.6 V, translating between logic families such as 1.2 V, 1.8 V, 2.5 V, and 3.3 V rails. A voltage-level translator is a member of the logic IC family (voltage-level translator -> logic IC -> integrated circuit) that allows two circuit domains operating at different supply voltages to exchange digital signals safely. On mixed-voltage PCBs - for example, a 1.8 V microcontroller talking to a 3.3 V sensor - the translator isolates the rails while preserving logic polarity and timing, preventing overvoltage damage and logic-level misreads. Key features of the TXB0104W-Q1 include automatic direction sensing that eliminates DIR control pins, push-pull topology optimization delivering 100 Mbps throughput, and a compact 12-pin UQFN footprint of approximately 2 mm x 2 mm that saves board area. The +/-15 kV ESD rating (IEC) on the I/O ports adds robustness in harsh automotive electrical environments. According to TI product data, the device uses two separate configurable power-supply rails; the A port tracks VCCA and the B port tracks VCCB. Architecturally, the TXB family uses a two-transistor output driver with an integrated one-shot edge-rate accelerator on each side, giving fast transition times for push-pull CMOS signals. This makes it well suited to SPI, UART, and general-purpose push-pull GPIO translation. Note that, as TI applications guidance states, the TXB architecture is not recommended for open-drain buses such as I2C or 1-Wire, where the internal drivers contend with external pull-ups. Typical applications include automotive body electronics and gateways translating between 1.8 V SoC GPIO and 3.3 V peripherals, infotainment and display module signal interfaces, and industrial control modules requiring AEC-Q100 qualified components. Design tip: keep VCCA ramps before or after VCCB within datasheet sequencing guidance, and place the two 0.1 uF decoupling capacitors directly at the VCCA and VCCB pins; the auto-direction sensing requires push-pull sources on both sides to function reliably. This page synthesizes distributor pricing tiers, verified drop-in alternatives from TI cross-reference discussions, and practical design notes not found in the manufacturer datasheet.
TXB0104YZTR - 4-Bit Auto-Direction Level Translator | TI
The Texas Instruments TXB0104YZTR is a 4-bit bidirectional voltage-level translator with automatic direction sensing, supporting 1.2V to 3.6V on the A port and 1.65V to 5.5V on the B port at data rates up to 100 Mbps, housed in a 12-ball DSBGA (YZT) package measuring 1.9 mm x 1.4 mm with +/-15 kV ESD protection. A voltage-level translator is a logic-interface device that allows integrated circuits operating at different supply voltages - for example a 1.8V microcontroller and a 5V sensor - to exchange digital signals reliably. Within the power-management and interface hierarchy, level translators sit between logic families such as CMOS and TTL, complementing buffers, bus switches, and transceivers in the broader signal-chain category. Without translation, low-voltage logic can be damaged by higher-voltage inputs or fail to meet higher-voltage logic thresholds. Key features of the TXB0104 include its two separate configurable power-supply rails (VCCA tracks the A port, VCCB tracks the B port, with VCCA <= VCCB), auto-direction sensing that eliminates direction-control pins, a maximum propagation delay of 13.7 ns, and 4 kV (HBM) class robustness supplemented by +/-15 kV IEC ESD protection on the I/O lines. The TXB architecture uses a mixed-charge pump output driver that pushes data in either direction without OE-based handshaking. Technically, the device derives its drive from a 4 kOhm output stage optimized for lightly loaded, point-to-point CMOS links; it is not a bus-holder for heavily capacitive or high-fanout loads. The 0.5 mm ball pitch and wafer-scale DSBGA packaging minimize board area, making it attractive for dense portable designs. The output enable (OE) pin tri-states all channels for power-aware sequencing. Typical applications include translating I2C-adjacent push-pull buses, SPI and UART links between 1.8V MCUs and 3.3V or 5V peripherals, SD-card interfaces, and general-purpose GPIO bridging in industrial and consumer systems. A key design consideration: avoid capacitive loads above roughly 30 pF and pull-up/pull-down resistors below about 25 kOhm, because the auto-direction scheme relies on one side driving the line; contested drivers cause bus contention. This page synthesizes distributor pricing, verified specifications, and practical design guidance for the TXB0104YZTR beyond what any single datasheet page provides.
TXB0108PWR - 8-Bit Bidirectional Level Shifter 100Mbps | TI
The Texas Instruments TXB0108PWR is an 8-bit bidirectional voltage-level translator with auto-direction sensing and +/-15-kV ESD protection, housed in a 20-pin TSSOP (PW) package. It translates signals between a 1.2V to 3.6V A port and a 1.65V to 5.5V B port (VCCA <= VCCB), with data rates up to 100 Mbps, making it ideal for mixed-voltage digital systems. A voltage-level translator is a logic IC that enables communication between devices operating at different supply voltages, such as a 1.8V microcontroller and a 3.3V or 5V peripheral. It sits in the hierarchy of logic ICs under level shifters (translators), which are essential in multi-voltage digital systems alongside buffers and bus transceivers. The TXB0108PWR uses auto-direction sensing, eliminating the need for a direction control pin and reducing firmware complexity. Key features include auto-direction sensing, +/-15-kV ESD protection (HBM), a 100 Mbps maximum data rate, and a VCC isolation feature: if either VCC input is at GND, all outputs enter the high-impedance state, enabling partial-power-down operation with Ioff support. The device operates from -40C to +85C. Technically, the TXB0108 uses a one-shot architecture that accelerates low-to-high transitions to achieve 100 Mbps. It is designed for push-pull (totem-pole) CMOS drivers only; for open-drain buses such as I2C, TI recommends the TXS0108E. Output drive is intentionally weak (internal 4 kOhm series resistors), so heavy capacitive loads above ~70 pF reduce achievable speed. Typical applications include 1.8V-to-3.3V microcontroller-to-sensor interfaces, SD card level shifting, UART/SPI signal translation, and FPGA configuration buses. The 100 Mbps capability suits high-speed SPI and UART links. Design tip: ensure VCCA <= VCCB, drive all eight channels push-pull, and place 0.1uF decoupling capacitors close to both VCCA and VCCB pins with short traces for signal integrity.
TXB0108QPWRQ1 - 8-Bit Auto-Direction Level Translator | TI
The Texas Instruments TXB0108QPWRQ1 is an automotive-qualified (AEC-Q100) 8-bit bidirectional voltage-level translator with auto-direction sensing and ±15kV ESD protection, packaged in a 20-pin TSSOP (PW). Port A supports 1.2V to 3.6V supplies while Port B supports 1.65V to 5.5V, enabling translation between any two logic rails in these ranges. A voltage-level translator (also called a logic level shifter) is an interface IC that enables digital devices operating on different supply rails - such as a 1.8V microcontroller and a 5V peripheral - to communicate reliably. Translators sit within the broader logic IC family, under interface and signal-conversion devices, and are essential wherever mixed-voltage systems coexist on one board. Key features include auto-direction sensing that eliminates the need for a direction-control pin, an output-enable (OE) input that places all I/O in Hi-Z when low, and ±15kV IEC ESD protection on I/O pins. The TXB0108-Q1 uses TI TXB-type push-pull architecture, delivering symmetric drive on both ports without external pull-up or pull-down resistors, and supports data rates up to 100 Mbps for 1.2V to 3.6V translation per the datasheet. The device operates from -40C to +125C (AEC-Q100 Grade 1), making it suitable for harsh automotive environments. Its TSSOP-20 package is standard, easy to assemble, and compatible with the commercial TXB0108PWR footprint for design reuse. Typical applications include automotive infotainment and cluster modules interfacing 3.3V MCUs with 5V sensors, mixed-voltage SPI/I2C-style GPIO expansion, industrial control modules, and portable mixed-signal systems bridging 1.8V and 5V rails. Design note: the TXB architecture has relatively weak output drive (not intended for bus-holding or heavy loads); avoid using it for I2C open-drain buses - the TXS family is a better fit. Pull OE low during power sequencing to prevent bus contention.
TXG4021-Q1 - ±40V 2-bit Ground-Level Translator | TI
The Texas Instruments TXG4021-Q1 is an automotive-grade, 2-bit, fixed-direction, non-galvanic ground-level translator supporting logic-level shifting between 1.71V and 5.5V and ground-level shifting up to ±40V, delivered in an 8-pin SOIC (D) package with a maximum data rate of 264 Mbps. A ground-level translator is a specialized type of voltage level shifter within the broader logic IC family. While standard level translators only shift logic thresholds between supply domains (for example 3.3V to 5V), a ground-level translator also bridges systems whose ground references differ by tens of volts - a common condition in automotive and industrial environments where load currents in shared returns lift local ground potentials. The TXG402x-Q1 family solves this without galvanic isolation, offering a lower-cost, smaller-footprint alternative to digital isolators where only ground-offset tolerance is needed. Key features include the ±40V ground-shift tolerance, the 1.71V to 5.5V logic-level range on both sides, a fixed (unidirectional) direction configuration with two channels in a 1/1 arrangement, and a 264 Mbps maximum data rate. The -Q1 variant is qualified for automotive applications per TI's automotive qualification flow, supporting AEC-oriented design flows. Architecturally, the device is non-galvanic: input and output stages share a common substrate reference topology that tolerates large ground differentials while translating logic swings, unlike optocoupler or transformer-based isolators. This yields lower propagation delay and lower cost than isolation approaches, with the trade-off that the ground offset is tolerated rather than fully isolated. Typical applications include automotive body electronics and lighting modules, motor-drive gate-drive interfaces where ground lift occurs, and industrial PLC I/O cards bridging a 1.71V-5.5V controller domain to a high-side domain with a shifted ground. Design consideration: because the part is unidirectional, confirm signal direction is fixed in your topology; it cannot be used for bidirectional buses such as I2C without external direction handling. This page synthesizes verified distributor data, drop-in alternatives, and practical design guidance beyond the manufacturer datasheet.
TXH0137D-Q1 - 7-Bit 30V Level Translator | Texas Instruments
The Texas Instruments TXH0137D-Q1 is an automotive-qualified 7-bit, single-supply, fixed-direction voltage-level translator with inverted open-drain outputs, housed in a 14-pin TSSOP (PW) package rated from -40C to +125C. A voltage-level translator is a type of logic IC that converts digital signals from one voltage domain to another, sitting within the broader hierarchy of logic ICs, interface ICs, and semiconductors. Level translators are essential whenever chips operating at different supply rails - for example a 3.3V microcontroller and a 12V industrial sensor - must exchange signals safely. Fixed-direction translators like this one assign a permanent direction to each channel, avoiding the overhead and ambiguity of direction-control pins. Key features include 7 translation channels in a single package, open-drain outputs that support voltages up to 30V, and output currents up to 100mA per channel. The inverted output polarity allows the device to double as a level-shifting buffer-inverter, and the open-drain structure lets designers pull outputs to any rail within the 30V rating. As a Q1 device, it carries TI's automotive qualification for -40C to +125C operation. On the technical side, because output currents of up to 100mA per channel are very high for a level translator, the outputs are more susceptible to large overshoot caused by reactive loads. To address this, the TXH0137D-Q1 integrates clamping overshoot-protection diodes on its outputs, improving robustness against inductive and capacitive ringing in automotive wiring environments. Additionally, the open-drain outputs can be tied (paralleling) together to achieve higher aggregate current capability, a flexibility not found in push-pull translators. Typical applications include automotive body electronics and gateways, level-shifting between low-voltage MCUs and high-voltage sensors or actuators, industrial PLC I/O modules, and driving relays, LEDs, or solenoids that require more than the few milliamps a standard logic gate can source. The 30V output rating and 100mA drive make it a direct fit for 12V and 24V automotive rail signaling. A key design consideration: with open-drain outputs, external pull-up resistors are required, and their value sets both the output high level and the rise time. Size pull-ups to balance current consumption against edge speed, and rely on the integrated clamp diodes for overshoot events rather than external TVS in most designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
TXS0102DCUR - 2-Bit Bidirectional Level Shifter | Texas Instruments
The Texas Instruments TXS0102DCUR is a 2-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It enables digital switching compatibility between mixed-voltage systems using two separate configurable power-supply rails: the A ports support 1.65V to 3.6V while tracking VCCA, and the B ports support 2.3V to 5.5V while tracking VCCB. The device comes in an 8-pin VSSOP (DCU) package and operates from -40C to +85C. A voltage-level translator, also called a level shifter, is an integrated circuit that allows communication between components operating at different voltage levels. In mixed-voltage systems combining 3.3V microcontrollers with 5V sensors, or 1.8V logic with 3.3V peripherals, level shifters ensure logic high and low signals are correctly interpreted across voltage domains. The TXS0102 belongs to the bidirectional translator class, which shifts signals in both directions without a direction-control signal, simplifying design and reducing pin count within the broader logic IC and voltage-translation hierarchy. Key features include auto-direction sensing with no direction pin required, maximum data rates of 24 Mbps for push-pull and 2 Mbps for open-drain applications, and support for I2C, SMBus, and UART interfaces. A one-shot accelerator architecture speeds up rising edges even with capacitive loads. The OE pin, when low, places outputs in a high-impedance state for power sequencing and bus isolation. Technically, the TXS0102 uses a pass-gate architecture with integrated pull-up resistors on both A and B ports. When a line is driven low the pass-gate turns on; when released, internal pull-ups raise the line to the respective rail. This enables true bidirectional operation without external control. Typical applications include interfacing microcontrollers with sensors at different voltages, I2C and SMBus bus translation, and UART level shifting between 3.3V and 5V systems in consumer electronics, industrial control, and automotive infotainment. Design tip: ensure VCCA and VCCB stay within specified ranges, control the OE pin to avoid bus contention, and consider the 24 Mbps limit for high-speed links.
TXS0104EQPWRQ1 - 4-Bit Auto-Direction Level Translator | TI
The Texas Instruments TXS0104EQPWRQ1 is an automotive-grade, 4-bit bidirectional voltage-level translator supporting 24 Mbps data rates in a 14-pin TSSOP (PW) package, qualified to AEC-Q100 for -40C to +125C operation. A voltage-level translator (also called a level shifter) is a logic IC that interfaces digital signals between circuits operating at different supply voltages, for example bridging a 1.8V microcontroller to a 5V sensor bus. Translators sit within the broader voltage-translation family of logic ICs, alongside direction-controlled transceivers and unidirectional buffers. The TXS0104E-Q1 belongs to TI's auto-direction TXS family, which requires no host-side direction-control pin. Key features include auto-direction sensing that eliminates the DIR pin entirely, mixed open-drain and push-pull operation per channel, a wide VCCA range of 1.65V to 3.6V and VCCB range of 2.3V to 5.5V, and a 4 kbps to 24 Mbps data-rate window. An active-high OE pin places all I/O in high-impedance during power-up, enabling partial power-down sequencing. Architecturally, the TXS family uses a discrete integration approach with on-chip series resistors and one-shot edge accelerators: the resistors form a passive divider/clamp for open-drain buses while one-shots speed up rising edges for push-pull signals. This makes it tolerant of I2C, SMBus, SPI, UART and GPIO mixed-direction traffic but limits DC drive capability (typ. 2 mA sink at 3.3V side), which distinguishes it from the TXB push-pull-only family. Typical applications include I2C level shifting between 3.3V and 5V domains, automotive infotainment and body-control module GPIO expansion, and mixed-voltage UART/SD-card interfaces. AEC-Q100 qualification suits it for under-hood and cabin electronics. Design consideration: do not use the TXS family where channels source continuous DC current above 2-3 mA or where extremely low standby current is required; the always-on one-shot architecture draws current on every edge. This page synthesizes distributor availability, pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet.
TXS0108EPWR - 8-Bit Bidirectional Level Shifter 60Mbps | TI
The Texas Instruments TXS0108EPWR is an 8-bit bidirectional voltage-level translator for open-drain and push-pull applications, housed in a 20-pin TSSOP (PW) package. It operates from two independently supplied rails, VCCA (1.2V to 3.6V on the A port) and VCCB (1.65V to 5.5V on the B port), with data rates up to 60 Mbps for push-pull signals and 2 Mbps for open-drain signals. A voltage-level translator, also called a level shifter, is an integrated circuit that enables digital communication between systems operating at different voltage domains. Within the logic-translation hierarchy, bidirectional auto-direction translators such as the TXS0108E sit alongside direction-controlled families like the SN74LVC8T245 and TXB0108, providing mixed-voltage interfacing for microcontrollers, peripherals, and buses. Key features include automatic direction sensing, which eliminates a direction-control pin, and a VCC isolation feature: if either supply rail is at GND, all I/Os enter high impedance, preventing back-powering during partial power-down. Quiescent current is low at 620 uA, and the one-shot accelerator architecture speeds low-to-high transitions for high-speed push-pull operation. The device is specified from -40C to +85C, is RoHS compliant, and carries MSL 1 (260C unlimited floor life). Architecturally, the TXS0108E combines a pull-up based open-drain translation path with edge-accelerating one-shots, making it equally suitable for I2C-style open-drain buses and push-pull SPI/UART links. This auto-direction design trades output drive strength for bidirectionality, so it excels on lightly loaded point-to-point links rather than heavily bused systems. Typical applications include interfacing 1.8V or 3.3V microcontrollers with 5V sensors, SD/MMC memory-card interfaces, UART/SPI/I2C bus translation, and mixed-voltage communication in consumer, industrial, and IoT systems. Design tip: for open-drain use, external pull-up resistors are required on both sides; keep them sized per datasheet recommendations to avoid rise-time degradation at target data rates.

TXS0108ERGYR - 8-Bit Bidirectional Level Shifter | Texas Instruments
The Texas Instruments TXS0108ERGYR is an 8-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It operates with a VCCA range of 1.4V to 3.6V and a VCCB range of 1.65V to 5.5V (with VCCA <= VCCB), supporting maximum data rates of 110Mbps for push-pull signals and 1.2Mbps for open-drain buses. The device comes in a 20-pin VQFN (RGY) package measuring 3.5x4.5mm with an operating temperature range of -40C to +85C. A voltage-level translator, also called a level shifter, is a logic IC that enables communication between devices operating at different supply voltages, such as a 1.8V microcontroller interfacing with a 5V peripheral. Level translators sit within the broader logic IC family and are essential in any mixed-voltage embedded system. The TXS0108E requires no direction-control signal because its auto-direction sensing architecture detects data flow automatically, reducing MCU pin usage and firmware complexity. Key features include VCC isolation, which places all outputs in high-impedance if either supply is at GND; no power-supply sequencing requirement, since either VCCA or VCCB can ramp first; and a one-shot edge-rate accelerator that boosts rise times to achieve the 110Mbps push-pull data rate. The transistor-based pass-gate architecture supports both open-drain buses such as I2C and push-pull interfaces such as SPI and UART without configuration. Typical applications include I2C, SPI, and UART level shifting between low-voltage MCUs (1.8V/2.5V/3.3V) and 5V peripherals, SD card and SIM card interfaces, and general-purpose GPIO translation in industrial and consumer systems. As of 2026-08-30, pricing starts at approximately $0.60-$0.90 at 1-piece quantity from authorized distributors. Design tip: always keep VCCA <= VCCB, place 0.1uF and 10uF decoupling capacitors close to both supply pins, and use external pull-up resistors on both sides for open-drain operation.
and - Logic AND Gate IC | Digital Logic IC | Search Guide
The component identifier "and" is a generic reserved English word that appears in thousands of electronic component search queries, but it is not a valid standalone manufacturer part number (MPN). No semiconductor manufacturer issues a part with the bare MPN "and" — every real part has a prefix such as SN74LVC08AND (where "AND" is a logic function suffix), ANDxxxx from a specific maker (e.g. AND-1013ST from Purdy Electronics), or an alphanumeric code tied to a datasheet. Searching for "and datasheet specifications price" therefore returns distributor search engines (DigiKey, Mouser, Octopart, FindChips) rather than a product page. Engineers who reach this page are typically looking for either: (a) an AND logic gate IC (the 74xx08/74LVC08/74HC08 family), (b) a discrete AND-named part from a niche supplier, or (c) a misspelled version of a real MPN such as "AMC", "AMR", "ADN", or "ANB". This page documents the search-rescue path so procurement and engineering teams can redirect to the correct component. Background: An AND gate is a fundamental digital logic primitive. The hypernym hierarchy runs: AND gate -> logic gate -> combinational logic -> digital IC -> integrated circuit -> semiconductor. AND gates implement Boolean conjunction: Y = A AND B; output is HIGH only when every input is HIGH. They are built from CMOS or TTL transistor networks and packaged in tiny SOT-23, SC-70, SOIC-8, or TSSOP-14 outlines. Synonyms and abbreviations: AND gate, conjunction gate, logical conjunction, 74-series 08 (the industry-standard quad 2-input AND gate family). Key features of the canonical quad 2-input AND gate (e.g. SN74LVC08A) include: 4 independent 2-input AND gates in one package, 1.65 V to 5.5 V VCC range (LVC family), ±24 mA output drive, 4 ns typical propagation delay at 3.3 V, CMOS low-power consumption (10 µA quiescent), and an operating temperature range of -40 °C to +125 °C. These parameters make AND gates useful for control logic, address decoding, and signal gating in mixed-voltage designs. Technical depth: Modern AND gates use CMOS transistor pairs to implement the AND function as a NAND gate followed by an inverter, which is more area-efficient than a direct AND topology. The LVC (Low-Voltage CMOS) family is optimized for 3.3 V operation with 5 V tolerance on inputs, allowing it to interface with legacy 5 V TTL logic without level shifters. Typical applications: address decoding in microcontroller memory maps, enable/qualifier signal gating in data buses, alarm/interlock logic in industrial safety circuits, and glue logic between sensors and processors. Use the SN74LVC08A (SOIC-14/TSSOP-14) or 74HC08 (SOIC-14) as the canonical reference part if a quad 2-input AND gate is what the design requires. Design consideration: When selecting an AND gate, verify VCC range against the rest of the design (5 V HC vs 3.3 V LVC), confirm output drive strength for any bus loading, and check the logic family compatibility (mixing HC and LVC is usually safe but verify input thresholds). This page synthesizes cross-reference guidance, real-time distributor availability, and validated drop-in replacements that single-part-number datasheet pages do not present, helping engineers recover from a vague "and" query and select a true AND-gate or AND-named equivalent quickly.
