The device performs the Boolean function Y = A · B in positive logic, making it a fundamental building block for digital decision-making and signal gating. An AND gate is a basic combinational logic gate that produces a HIGH output only when all of its inputs are HIGH. Logic gates are the fundamental building blocks of digital integrated circuits, sitting at the lowest level of the digital design hierarchy: logic gate -> combinational logic -> sequential logic -> microcontroller / ASIC. The AHC family is a higher-speed, lower-power evolution of the classic HC (High-Speed CMOS) family, designed for low static power consumption while delivering faster switching than HC and lower switching noise than TTL. Key features include a wide 2 V to 5.5 V operating range, ±8 mA balanced output drive at 5 V, 10 µA maximum quiescent supply current (Icc), and a Schmitt-trigger action on the inputs that makes the device tolerant of slowly rising edges. The SOT-23-5 footprint (DBV) is one of the industry's smallest logic-gate packages, enabling high-density board layouts in space-constrained designs. The device is also characterized for operation over the -55 °C to +125 °C free-air temperature range, suitable for industrial and harsh-environment applications. Internally, the SN74AHC1G08 uses a standard CMOS push-pull output stage with a buffered input. The Schmitt-trigger input hysteresis typically exceeds 1 V at 5 V, which improves noise immunity in environments with slow or noisy input edges. The wide Vcc range allows the part to translate logic levels between 3.3 V and 5 V domains without external level shifters, useful when interfacing microcontrollers, sensors, and older 5 V peripherals. Typical applications include power-rail sequencing and control logic in portable and battery-powered devices, enabling logic and control in industrial sensor interfaces, level shifting between 3.3 V and 5 V rails, general-purpose glue logic in microcontroller-based embedded designs, and signal gating in test and measurement equipment. The wide supply range and small package make it a versatile companion to virtually any digital subsystem. When designing with this device, place a 0.1 µF decoupling capacitor as close as possible to the Vcc pin and minimize input trace lengths to avoid noise-induced glitches. Because this is a non-inverting AND function, be aware that it cannot be used as a NAND; if inverted output is required, cascade with an inverter such as SN74AHC1G04 in the same SOT-23-5 package.

The Texas Instruments SN74AHC373PWR is an octal transparent D-type latch with 3-state outputs, operating from 2V to 5.5V VCC, housed in a 20-pin TSSOP (PW) package. It provides eight D-type latches organized as a single 8:8 channel with non-inverting transparent latch behavior, controlled by a latch-enable (LE) input and an active-low output-enable (OE) bar input that places outputs in high-impedance state. A latch is a sequential storage element that captures data when the latch-enable is asserted and holds it transparently or in storage mode. As a member of the AHC (Advanced High-speed CMOS) family, this device is pin-compatible with the HC (High-speed CMOS) logic family while delivering lower static power and faster switching at 5V operation. The latches occupy a position in the logic hierarchy between simple flip-flops and bus-oriented register files, making them ideal for address/data bus demultiplexing, I/O port expansion, and state retention in microcontroller-based systems. Key features include a typical propagation delay of 8.5 ns at 5V, support for +/-8 mA output drive, and ESD protection exceeding JESD 22 (2000V human-body model, 200V machine model, 1000V charged-device model). The device offers low power consumption with a typical quiescent current of 4 uA, supports +/-50 mA bus-hold and bus-drive, and provides true 5V tolerant inputs on a 2V-5.5V supply rail. Internally, the SN74AHC373 uses eight transparent D latches each with a 3-state output buffer. When LE is HIGH, the latch is transparent and follows the D input; when LE falls LOW, the value is stored. The OE bar pin enables the output buffers; when OE bar is HIGH, outputs are high-impedance. This architecture is widely used as a simple 8-bit data register or address demultiplexer. Typical applications include LED driving via 8-bit port expansion, address demultiplexing in microcontroller memory interfaces, bus isolation in mixed-voltage systems, and general-purpose 8-bit data storage. The wide 2V-5.5V range enables direct interfacing between 3.3V MCUs and 5V peripherals. When designing with this part, ensure that OE bar is properly tied to GND through a pull-down resistor if not actively driven, to prevent floating outputs. Unused D inputs should be tied to VCC or GND to avoid floating CMOS inputs. The TSSOP-20 package has a low thermal resistance suitable for industrial temperature operation.

The Texas Instruments SN74ALVCH162373 is a 16-bit transparent D-type latch with 3-state outputs, part of the ALVCH low-voltage CMOS Widebus family. It operates from a 2.3V to 3.6V supply and can function as two independent 8-bit latches or one 16-bit latch, controlled by latch-enable (LE) and output-enable (OE) inputs. When LE is high, the Q outputs follow the D inputs; when LE is low, the outputs hold the last data. A transparent latch is a sequential logic component that passes input data to outputs while enabled and stores the last value when disabled. It sits in the hierarchy: transparent latch -> D-type latch -> latch -> sequential logic -> digital logic IC, and is a fundamental building block for data storage, synchronization, and bus interfacing in digital systems.

An inverter gate is a single-input logic gate whose output is the logical complement of its input; it belongs to the broader category of logic gates within the digital IC hierarchy (logic gate -> combinational logic -> digital IC -> semiconductor). The AUP family is engineered specifically for battery-powered portable equipment where quiescent current draw and dynamic power consumption dominate battery life, making the SN74AUP1G04 well suited for applications that must remain powered continuously. Key features include a maximum quiescent current (ICC) of 0.9 µA, a typical dynamic power capacitance (Cpd) of 4.1 pF at 3.3 V, low input capacitance of 1.5 pF typical, and Schmitt-trigger action that keeps output noise (overshoot/undershoot) below 10 percent of VCC. Ioff circuitry supports partial-power-down by preventing damaging backflow current when the device is unpowered. The SC-70-5 footprint occupies approximately 2.0 mm x 1.25 mm on the PCB, supporting the densest of portable layouts. Internally, the SN74AUP1G04 uses a CMOS silicon-gate implementation that delivers rail-to-rail input and output swing, nanoStar and nanoFree package options, and an output drive of ±4 mA at 3.3 V. Typical propagation delay is around 4 ns at 3.3 V with a 30 pF load, which is fast enough for moderate-speed control and general-purpose logic glue but not optimized for high-speed buses. Typical applications include battery-powered portable medical devices, wearable fitness monitors, hand-held consumer electronics, ultra-low-power IoT sensor nodes, signal conditioning in microcontroller I/O expansion, and level translation between low-voltage MCU domains and 3.3 V peripherals. Designers use the SN74AUP1G04 wherever a single complementary logic signal is needed alongside an ultra-low-power MCU. When designing with this device, observe the recommended decoupling capacitor (0.1 µF ceramic) placed as close as possible to the VCC pin to control supply-induced jitter, and respect the absolute maximum VCC of 4.6 V to avoid latch-up. For partial-power-down rails, the Ioff feature removes the need for external protection diodes.

The Texas Instruments SN74AUP1G14DRLR is a single-channel low-power Schmitt-trigger inverter in a 5-pin SOT-553 (DRL) package, designed for ultra-low-power operation from 0.8 V to 3.6 V VCC. According to TI's SN74AUP1G14 family datasheet, the device features 0.9 uA maximum quiescent current (ICC), 4.4 pF typical power dissipation capacitance (Cpd), and 1.5 pF typical input capacitance. Schmitt-trigger inputs provide hysteresis for noise immunity on slow or noisy edges. A Schmitt-trigger inverter is a logic gate that combines inversion with a hysteretic input threshold, preventing oscillation on slow or noisy input transitions. The AUP (Advanced Ultra-low Power) sub-family belongs to TI's CMOS logic portfolio, optimized for battery-powered and energy-harvesting applications. Within the logic hierarchy, inverters fall under gates -> combinational logic -> standard logic ICs. Schmitt-trigger variants are specifically designed for signal conditioning, oscillator circuits, and debouncing, where slow-rising signals (such as RC-filtered edges or mechanical switch closures) would otherwise cause multiple transitions on a standard CMOS input. Key features of the SN74AUP1G14 include partial-power-down capability through Ioff circuitry (preventing backflow current when the device is unpowered), NanoStar and NanoFree tiny package options, low overshoot/undershoot (<10% of VCC), and balanced 4 mA output drive at 3.3 V. The device is specified across the industrial -40C to +85C operating range and supports standard logic-level translation in mixed-voltage systems. The internal architecture uses TI's advanced CMOS process with hysteresis built into the input stage. The Schmitt-trigger threshold is approximately 0.65*VCC (rising) and 0.35*VCC (falling), giving roughly 30% VCC hysteresis. The Ioff feature protects downstream circuitry by blocking current paths through the I/O pins when VCC = 0 V, which is essential for systems where the SN74AUP1G14DRLR is powered down while the upstream bus remains live. Typical applications include button debouncing in handheld devices, RC relaxation oscillators, level translation between 1.8 V and 3.3 V domains, and signal conditioning for sensors. The 5-pin SOT-553 footprint is among the smallest single-gate packages available, making the device ideal for space-constrained wearables and IoT sensor nodes. When designing with this device, ensure input signal rise/fall times are slower than the typical CMOS transition rate to benefit fully from the Schmitt-trigger hysteresis. Place a 0.1 uF decoupling capacitor as close as possible to the VCC pin to suppress noise-induced threshold violations.

The 3-state output places the /Y pin in a high-impedance state when /OE is high, enabling shared-bus and point-to-point architectures. Technically, the device uses CMOS circuitry optimized for very low dynamic power, maintaining excellent signal integrity even at reduced supply rails such as 1.2 V or 1.8 V, which are common in battery-powered portable applications. Typical applications include level-compatible signal buffering in smartphones, tablets, and wearables, bus isolation in battery-powered portable electronics, and point-to-point line driving in low-power industrial and IoT nodes. A key design consideration is that the /OE enable is active-low: pull /OE high to tri-state the output. Decouple VCC with a 0.1 uF ceramic capacitor close to pin 5.

It operates over a 0.8 V to 3.6 V VCC supply range, consumes less than 1 uA of quiescent supply current (ICC max 0.9 uA), and delivers 4 mA typical output drive at 1.8 V VCC. An OR gate is a fundamental combinational logic building block that outputs a HIGH state whenever any of its inputs is HIGH; it sits within the broader Boolean logic IC hierarchy as one of the seven primitive gates and is foundational for implementing sum-of-products expressions, control signal arbitration, and discrete decision logic in digital systems. The AUP sub-family is optimized for battery-powered portable applications where leakage current dominates total power budget, providing CMOS-equivalent speed at one to two orders of magnitude lower static consumption than standard HC/HCT logic. Key features of the SN74AUP1G32DCKR include a propagation delay of approximately 3.4 ns typical at 3.3 V VCC (load-dependent), partial-power-down support via Ioff circuitry that prevents back-drive current when the device is unpowered, over-voltage tolerant inputs that accept signals up to 3.6 V regardless of VCC, low input capacitance of 1.5 pF typical for reduced dynamic loading, and ±10% VCC overshoot/undershoot immunity on switching edges. The push-pull CMOS output stage eliminates the need for external pull-up resistors required by open-drain alternatives, simplifying PCB layout. The AUP1G32 architecture uses a single-stage OR topology with internal buffering to ensure consistent output drive strength across the full VCC range. Its sub-1 uA ICC at 25 °C makes it among the lowest-leakage single-gate OR functions available, while the Ioff feature enables safe insertion into mixed-voltage rails and partial-power-down subsystems without latch-up. Typical applications include handheld consumer electronics, battery-powered sensor front-ends, IoT edge nodes, wearable devices, low-power MCUs as a logic-level adapter, and any compact PCB where a single discrete OR function is required alongside a multi-channel logic IC. Designers frequently pair the AUP1G32 with 1.8 V microcontrollers such as the MSP430 or SimpleLink families for status-flag combination, interrupt arbitration, and power-rail selection gating. When designing with this part, observe 3.6 V as the absolute maximum VCC and avoid DC loading on inputs above VCC; for high-speed paths above 50 MHz, verify propagation delay under actual load capacitance rather than relying on the typical datasheet figure.

SN74AUP1T34-Q1 - 1-Bit Dual-Supply Level Translator | Texas Instruments
The Texas Instruments SN74AUP1T34-Q1 is a 1-bit unidirectional, noninverting voltage-level translator that operates from two separate configurable power-supply rails (VCCA and VCCB). It translates logic signals from A to B and comes in a 5-pin SC-70 (DCK) package qualified to AEC-Q100 for automotive applications, operating from -40C to +125C. A voltage-level translator is a logic IC that converts signals between two different voltage domains, allowing a 1.8V microcontroller to safely drive a 3.3V peripheral or vice versa. Translators sit within the broader logic IC family, alongside buffers, gates, and bus switches, and are essential wherever mixed-voltage systems interface. Key features include dual-supply operation enabling level translation in either direction (up or down), the AUP (Advanced Ultra-low Power) process family for very low dynamic power consumption, and push-pull output structure that removes the need for pull-up resistors required by open-drain translators. Per the TI datasheet, pin A is referenced to VCCA and receives the signal to be translated. The device belongs to TI's AUP1T single-gate translator family, which combines tiny single-gate packaging with wide supply flexibility, making it suitable for space-constrained automotive modules. The noninverting buffer topology preserves signal polarity with minimal propagation delay. Typical applications include automotive body electronics and lighting modules, level-shifting between 1.8V MCUs and 3.3V CAN or LIN transceivers, interfacing low-voltage sensors to higher-voltage logic, and general-purpose single-bit signal conversion in infotainment and cluster designs. Design consideration: ensure both supply rails are within the datasheet-recommended ranges and observe power-up sequencing guidance in the datasheet to avoid undefined outputs during startup. Because this is a unidirectional translator, the signal must always flow from pin A to pin Y/B.
SN74AUP1T34DSFR - 1-Bit Level Translator X2SON-6 | Texas Instruments
The Texas Instruments SN74AUP1T34DSFR is a 1-bit non-inverting unidirectional voltage-level translator in a 6-pin X2SON (DSF) package measuring 1x1 mm, operating over -40C to +85C. It uses two separate configurable power-supply rails, allowing logic signals to be translated between voltage domains such as 1.8V-to-3.3V or 1.2V-to-2.5V systems. A voltage-level translator is a member of the logic IC family (buffers, drivers, level translators within the broader category of digital integrated circuits) that converts digital signals from one logic-voltage domain to another. As process nodes shrink, modern MCUs, FPGAs, and sensors run on cores as low as 0.8V to 1.8V, while legacy peripherals, LEDs, and actuators still operate at 2.5V, 3.3V, or 5.5V. A dual-rail translator such as the SN74AUP1T34 bridges these domains safely, protecting input structures and guaranteeing valid logic levels on both sides. Key features include the AUP (Advanced Ultra-low Power) process family, known for the lowest dynamic power consumption in the TI small-signal logic portfolio, a push-pull (totem-pole) output that eliminates the need for an external pull-up resistor, and a non-inverting buffer function that preserves signal polarity. The tiny 1x1 mm X2SON footprint suits densely packed wearable, mobile, and IoT boards where every square millimeter counts. Technically, the device is a single-channel translator with the A port referenced to VCCA and the B port referenced to VCCB. Because the output is push-pull rather than open-drain, it delivers symmetric rise and fall times with lower static current than open-drain solutions. The Ultra-low-power AUP technology keeps dynamic power low during signal transitions, extending battery life in portable designs. Typical applications include GPIO level translation between microcontrollers and peripherals, I2C-adjacent and UART/SPI signal translation in portable consumer electronics, and interfacing low-voltage sensor outputs to higher-voltage logic in battery-powered IoT nodes. Design tip: power up VCCA before or together with VCCB and keep both rails within the datasheet-recommended operating window; decouple each rail with a 100 nF ceramic capacitor placed as close as possible to the pins to suppress transients on this compact package.

SN74AUP1T34QDCKRQ1 - AEC-Q100 1-Bit Level Translator | TI
The Texas Instruments SN74AUP1T34QDCKRQ1 is an AEC-Q100 qualified 1-bit unidirectional non-inverting voltage-level translator with dual configurable power-supply rails supporting VCCA and VCCB from 0.9V to 3.6V each, housed in a 5-pin SC-70 (DCK) surface-mount package rated from -40C to +125C. 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 connecting a 1.8V microcontroller output to a 3.3V peripheral input. Level translators sit within the broader logic IC family (buffers, translators, transceivers) and are essential wherever mixed-voltage domains coexist, which is nearly every modern embedded system. Key features include two independent supply rails (VCCA and VCCB) that can each be set anywhere from 0.9V to 3.6V, allowing any-to-any translation between common logic levels such as 1.2V, 1.5V, 1.8V, 2.5V and 3.3V. The push-pull (non-inverting) output drives the signal actively in both directions, eliminating the need for external pull-up resistors required by open-drain solutions. The AUP (Advanced Ultra-low-Power) silicon technology delivers low dynamic power consumption, making the device attractive for battery-powered automotive and portable designs. Architecturally, pin A is referenced to VCCA and receives the input signal, while pin B is referenced to VCCB and transmits the level-shifted output. Because both supplies support the same 0.9V to 3.6V range, the translator is direction-agnostic in voltage terms: it can translate low-to-high or high-to-low. TI controls the data sheet SN74AUP1T34-Q1, and the -Q1 suffix denotes AEC-Q100 automotive qualification including extended -40C to +125C operation. Typical applications include automotive body electronics and ADAS sensor interfaces, I2C/SPI/UART signal translation between mixed-voltage ICs, GPIO level conversion in battery-powered portable equipment, and general-purpose 1-bit buffering in industrial control modules. Design consideration: both VCCA and VCCB must be decoupled with 0.1uF ceramic capacitors placed close to pins 4 and 5, and the unused input should never be left floating since the AUP family inputs must be tied high or low. This page adds value beyond the TI datasheet by synthesizing distributor pricing as of 2026-09-04, drop-in alternative analysis, and practical layout notes in one place.
SN74AUP2G126YZPR - Dual Bus Buffer 3-State 8-DSBGA | TI
The Texas Instruments SN74AUP2G126YZPR is a low-power dual bus buffer gate with 3-state outputs, offered in an 8-bump DSBGA (YZP) package. Each of its two channels is a non-inverting buffer with an independent output-enable input, allowing designers to place individual channels in a high-impedance state for bus-isolation or multiplexing duties. The AUP logic family targets battery-powered portable applications where dynamic and static current draw both matter. A bus buffer (or line driver) is a digital circuit element that reproduces a logic input at its output while providing higher drive strength, level translation, or bus-isolation capability. Within the broader taxonomy, a bus buffer belongs to the logic ICs category (sub-family: buffers/drivers/receivers) and falls under the CMOS logic umbrella alongside gates, inverters, and transceivers. Buffers are functionally distinct from transceivers: a buffer is unidirectional, while a transceiver is bidirectional and typically includes bus-side termination. The AUP family is TI's premier low-power CMOS sub-family, designed for sub-1 GHz edge rates and sub-microamp quiescent current budgets, sitting between the AUC (1.8-V optimized) and LVC (general-purpose) families in TI's logic-portfolio positioning. Key features include an operating voltage range of 0.8 V to 3.6 V across VCC, partial-power-down support via Ioff (live-insertion safe), 3.6-V tolerant inputs when VCC is at 3.3 V, low static and dynamic power consumption characteristic of AUP logic, and a maximum quiescent current in the microamp range. Each output stage uses TI's standard 3-state architecture, with an active-high output enable (OE) per channel. The 8-ball DSBGA package keeps the footprint extremely small - approximately 0.9 mm x 0.9 mm - making the part suitable for space-constrained wearables and handhelds. Architecturally, the SN74AUP2G126 uses TI's AUP silicon-gate CMOS process with industry-standard Schmitt-trigger inputs (partial), low-drive-strength CMOS outputs, and the Ioff feature that prevents back-feeding current into a powered-down output pin. Inputs are tolerant up to 3.6 V regardless of VCC, providing robust interface to 1.8 V, 2.5 V, and 3.3 V domain signals without external protection. Typical applications include smartphones and wearables, IoT sensor nodes, low-power portable instrumentation, voltage-level shifting between 1.2 V microcontrollers and 3.3 V peripherals, and any system needing bus multiplexing or isolation with minimal quiescent power. The 3-state outputs allow direct bus sharing with other drivers under careful OE arbitration. Designers should note that the DSBGA package requires reflow soldering with appropriate profile and that the small land pattern demands careful PCB layout and precise stencil design to avoid defects. When designing with this part, ensure that the OE pins are properly managed during power-up to prevent bus contention; pull OE to a defined logic level at startup rather than leaving them floating.
SN74AVC4T234 - 4-Bit Dual-Supply Level Translator | TI
The SN74AVC4T234 is a 4-bit, dual-supply noninverting voltage level translation device from Texas Instruments. It is designed to facilitate asynchronous communication between B-port inputs and A-port outputs, with each port referenced to its own supply rail (VCCB and VCCA). The device operates across a wide VCC range of 0.9 V to 3.6 V, making it suitable for low-power, battery-powered portable applications where both static and dynamic power consumption must be minimized. A voltage level translator, also known as a level shifter, is a type of logic IC that allows digital signals to be transferred between circuits operating at different voltage levels. It is essential in mixed-voltage systems, such as interfacing a 1.8V microcontroller with a 3.3V peripheral. The SN74AVC4T234 belongs to the AVC family of advanced very-low-voltage CMOS logic, which is optimized for high-speed operation with minimal power consumption. Key features of the SN74AVC4T234 include its dual-supply configuration, which provides independent power rails for each port, ensuring proper voltage translation without signal distortion. The device maintains excellent signal integrity across the entire VCC range, and its low static and dynamic power consumption extends battery life in portable devices. The noninverting architecture preserves signal polarity, simplifying system design. Technically, the SN74AVC4T234 uses a configurable voltage translation scheme that automatically adjusts output drive strength based on the supply voltage. This ensures reliable operation even with varying supply levels. The device is available in a small package, making it ideal for space-constrained applications. Its propagation delay is minimal, supporting high-speed data transfer. Typical applications include interfacing between different voltage domains in smartphones, tablets, and other portable electronics, as well as in industrial control systems where sensors and microcontrollers operate at different voltages. The device is also used in networking equipment and data communication systems. When designing with the SN74AVC4T234, ensure that both VCCA and VCCB are powered and within the specified range. Proper decoupling capacitors should be placed near the supply pins to maintain stable operation. The device supports bidirectional level translation, but the direction is controlled by the DIR pin, which must be set correctly for the desired data flow.
SN74AVC4T245PWR - 4-Bit Dual-Supply Level Shifter | TI
The Texas Instruments SN74AVC4T245PWR is a 4-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs, supplied in a 16-pin TSSOP (PW) package. It operates from two independent supply rails, VCCA and VCCB, each ranging from 0.8V to 3.6V, enabling bidirectional level shifting between mixed voltage domains such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. A bus transceiver is a digital integrated circuit that transfers data bidirectionally between two buses, using direction-control and output-enable inputs plus 3-state outputs so multiple devices can share a common bus. The SN74AVC4T245 belongs to the voltage translator (level shifter) family within the broader logic IC and interface IC hierarchy, and it is essential in mixed-voltage systems where MCUs, FPGAs, sensors, and memory operate at different logic levels. Key features include configurable voltage translation on both ports, control inputs (1DIR, 2DIR, 1OE, 2OE) referenced to VCCA for simplified control logic, and Ioff partial-power-down circuitry that disables outputs and prevents damaging backflow current when either rail is at GND. A VCC isolation feature places all I/O in high-impedance if either supply is absent. Technically, the device supports asynchronous communication between two data buses at data rates up to 380 Mbps with a typical propagation delay around 2.5 ns, suiting high-speed SPI, parallel bus, and GPIO interfaces. The TSSOP-16 package has a 4.4mm body width and 0.65mm pin pitch for space-constrained PCBs. Typical applications include level shifting for SPI, UART, I2C-adjacent GPIO expansion, and FPGA or ASIC interconnects in industrial control, portable battery-powered electronics, and automotive modules where multiple voltage domains coexist. Design tip: keep the DIR and OE pins driven from VCCA-domain logic and place 0.1uF decoupling capacitors close to both VCCA and VCCB pins; avoid bus contention by sequencing direction changes with a brief high-impedance interval.
SN74AVC8T245DGVR - 8-Bit Dual-Supply Bus Transceiver | TI
The Texas Instruments SN74AVC8T245DGVR is an 8-bit dual-supply bus transceiver with configurable voltage-level shifting and 3-state outputs, housed in a 24-pin TVSOP (DGV) package. It supports data translation between two independently configurable voltage rails from 1.2 V to 3.6 V on VCCA and 1.2 V to 3.6 V on VCCB, with direction control via the DIR pin and output enable via the active-low OE pin. The device delivers high-speed signal transmission with typical propagation delay of approximately 2.5 ns at 3.3 V and ±12 mA output drive strength. A dual-supply bus transceiver is a logic IC that bridges two voltage domains in a digital system, allowing a microcontroller or ASIC on one rail (for example 1.8 V) to communicate with peripherals or memory on another rail (for example 3.3 V). The 'dual-supply' architecture uses two independent VCC pins (VCCA and VCCB) so each side of the transceiver references its own rail. Within the broader product taxonomy, this part belongs to the level shifter / voltage translation transceiver family, which sits under interface ICs and ultimately under integrated circuits. Key features of the SN74AVC8T245 include Ioff partial-power-down support for live insertion and hot-swap scenarios, VCC isolation that forces all I/O into high-impedance when either supply is at GND, and bus-hold circuitry on the data I/Os to eliminate the need for external pull-up or pull-down resistors. The DIR pin controls signal direction (A-to-B or B-to-A), and OE disables the outputs when high. The wide 1.2 V to 3.6 V operating range covers all common logic standards including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and lower-voltage CMOS. Architecturally, the device uses TI's AVC (Advanced Very-low-voltage CMOS) process technology, which combines low static power consumption with high drive strength and fast edge rates. The integrated bus-hold cells use weak feedback transistors to retain the last driven logic state on floating lines, eliminating external bias resistors. Ioff circuitry blocks the internal parasitic diode paths when VCC is removed, so the part can be safely inserted or removed from a powered backplane. Typical applications include level shifting between a 1.8 V host processor and 3.3 V peripherals, I2C or general-purpose GPIO expansion, SD-card or SIM-card interfaces, and translating logic between FPGAs and DDR memory rails. The wide voltage range makes it useful in industrial, consumer, and portable battery-powered designs. When designing with this part, place a 0.1 µF decoupling capacitor on each VCC pin and route the DIR and OE pins directly to a GPIO of the controlling host. Avoid leaving either VCC pin floating; unused VCC must be tied to its corresponding rail or to GND to ensure proper high-impedance behavior. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, helping engineers select and source the part efficiently.
SN74AVCB164245GR - 16-Bit Dual-Supply Level Translator | Texas Instruments
The Texas Instruments SN74AVCB164245GR is a 16-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs, housed in a 48-pin TSSOP (DGG) package. It supports bidirectional level translation between two supply rails from 1.4 V to 3.6 V on the A-port and 1.4 V to 3.6 V on the B-port, with separate VCCA and VCCB power pins per port group enabling asymmetric voltage domains. A bidirectional level translator (also called a voltage level shifter) is an integrated circuit that safely bridges two subsystems operating at different logic-voltage rails. The SN74AVCB164245 belongs to the widebus transceiver family and provides 16 channels split into two 8-bit groups, each with its own direction-control pin. This device class is essential in mixed-voltage systems where modern processors operate at 1.8 V or 1.2 V while legacy peripherals, memories, or bus interfaces remain at 2.5 V or 3.3 V. Key features include a typical propagation delay of 3.7 ns (VDD = 3.3 V), ±12 mA drive strength per channel, 3.5 ns maximum output skew, and partial-power-down capability through Ioff circuitry that prevents damaging backflow current when the device is unpowered. The DIR inputs set the direction of data flow per 8-bit bank, while the OE pins place outputs in high impedance for bus isolation. The SN74AVCB164245 uses TI's DOC (Dynamic Output Control) circuitry, which dynamically switches output impedance to reduce line-noise transients without external damping components. This active damping eliminates the typical ringing seen on heavily loaded memory buses, which improves signal integrity at high data rates. Typical applications include memory-card interfaces between SoCs and DDR/LPDDR memories, GPIO expansion between low-voltage MCUs and 3.3 V peripherals, FPGA-to-MCU bridge logic in industrial controllers, I2C/SPI/UART bridge isolation, and smartphone baseband-to-application-processor interconnects. The dual-supply design is particularly suited to portable electronics where minimizing both voltage drop and leakage current is critical. When designing with this device, ensure VCCA and VCCB rails are decoupled with 0.1 uF ceramic capacitors placed within 5 mm of the supply pins. The OE and DIR logic thresholds are referenced to their respective supply rails, so control signals must be level-shifted into the appropriate domain. Avoid leaving OE floating; tie through a 10 kohm resistor to the high-side supply rail of the controlling port.

SN74AXC4T774BQBR - 4-Bit Dual-Supply Bus Transceiver | Texas Instruments
The Texas Instruments SN74AXC4T774BQBR is a 4-bit dual-supply bus transceiver with configurable voltage translation, independent direction control inputs, and 3-state outputs, housed in a 16-pin WQFN package (2.5 mm x 3.5 mm). It supports an input voltage range of 0.65 V to 3.6 V on the A-port and 0.65 V to 3.6 V on the B-port, allowing seamless level shifting between any two voltage nodes from 0.65 V up to 3.6 V without external direction-control logic. The SN74AXC4T774 belongs to the bus transceiver / level shifter category (a sub-family of voltage level translators within interface ICs / logic ICs). Level translators are interface ICs that allow digital signals to pass between two parts of a system that operate at different supply voltages. They are an essential building block in mixed-voltage designs where low-voltage processors and ASICs must communicate with legacy 1.8 V, 2.5 V, or 3.3 V peripherals, and they enable designers to maintain backwards compatibility while taking advantage of new low-voltage cores. Key features of the SN74AXC4T774 include a typical data rate of 110 Mbps, 4.4 ns typical propagation delay, partial-power-down support via Ioff, and a control-pin reference (DIR and OE) tied to VCCA for simple GPIO-driven control. The AXC family offers the industry's lowest static power consumption in this class, helping portable and battery-powered designs extend runtime without sacrificing throughput. The internal architecture uses TI's AXC CMOS technology with one-shot edge accelerators that detect rising or falling edges on the I/O pins and briefly speed up the output drivers to achieve high data rates with low dynamic power. The DIR pin determines signal direction, while OE enables a high-impedance output mode for bus isolation. Both A and B ports support 3.6-V tolerant I/O on the lower-voltage side, simplifying board design. Typical applications include I2C / SPI / UART bridging between low-voltage SoCs and 3.3 V peripherals, MIPI / camera-serializer voltage translation, SD-card level shifting, and general-purpose GPIO expansion in industrial controllers, wearables, and portable IoT endpoints. A key design consideration is to always tie the OE pin to VCCA through a pull-up resistor (or to a dedicated GPIO) so that the I/Os enter high-impedance during power-up or power-down, preventing bus contention and back-powering.
