Product details
Overview
74LVC1G175DBVRG4 from Texas Instruments is a single D-type flip-flop with asynchronous clear, designed for 1.65-V to 5.5-V operation. It features a rising-edge-triggered clock input (CLK), active-low asynchronous clear (CLR), and delivers 4.3 ns max propagation delay at 3.3 V. Used in serial shift register stages and digital signal storage within compact logic subsystems.
For engineers reviewing the 74LVC1G175DBVRG4 datasheet, 74LVC1G175DBVRG4 pinout, 74LVC1G175DBVRG4 application, or 74LVC1G175DBVRG4 equivalent, key selection criteria include its 6-pin SOT-23 package, ±24-mA output drive at 3.3 V, Ioff support for live insertion, and guaranteed operation from –40°C to 125°C.
Technical Context
This device implements a positive-edge-triggered D flip-flop with an independent asynchronous reset path. Its CLR input forces Q low regardless of CLK state or D value, enabling immediate state clearing without clock dependency.
The logic core operates across 1.65–5.5 V VCC, with 5.5-V-tolerant inputs supporting mixed-voltage interfacing and down-translation. Ioff circuitry disables outputs during partial power-down, preventing back-drive current when VCC = 0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| Max tpd | 4.3 ns at 3.3 V - enables reliable operation up to 150 MHz clock frequency in 3.3-V systems |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive standard CMOS loads and small capacitive buses without buffering |
| Ioff Support | Yes - prevents backflow current during power sequencing or hot-swap events in multi-rail systems |
| ESD Rating | 2000-V HBM - meets industrial-grade robustness requirements for board-level handling and integration |
| Operating Temp | –40°C to 125°C - qualified for automotive under-hood, industrial control, and telecom infrastructure use |
Pinout & Package
74LVC1G175DBVRG4 is housed in a 6-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CLK | Clock Input | Rising-edge-sensitive timing input; triggers synchronous data capture from D to Q |
| 2 - GND | Ground Reference | Primary return path for logic and output currents; must be low-impedance for noise immunity |
| 3 - D | Data Input | Asynchronous data source; sampled on CLK rising edge when CLR is high |
| 4 - Q | Noninverting Output | Registered output reflecting D state after CLK edge; drives downstream logic or bus lines |
| 5 - VCC | Supply Voltage | Power rail for internal logic and output buffers; requires local 0.1-µF bypass capacitor |
| 6 - CLR | Asynchronous Clear Input | Active-low reset; forces Q low immediately, overriding CLK and D regardless of timing |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ Package | Die-as-package construction reduces footprint to 2.90 mm × 1.60 mm while maintaining thermal and mechanical reliability |
| 5.5-V Tolerant Inputs | Accepts input signals up to 5.5 V even when VCC = 1.65 V - enables seamless level translation without external components |
| Live Insertion Support | Ioff functionality disables outputs when VCC = 0 - permits safe hot-plug operation in modular backplane or card-edge systems |
| Latch-Up Immunity | Exceeds 100 mA per JESD78 Class II - ensures robustness against transient overvoltage and ground bounce in noisy environments |
| Low ICC | 10 µA max supply current - minimizes quiescent power in battery-backed or always-on logic monitoring circuits |
Applications
| Serial Shift Register Stage | Digital Signal Storage |
|---|---|
Use Scenario: Cascading four 74LVC1G175DBVRG4 devices to build a 4-bit serial-in/serial-out shift register for data serialization in microcontroller peripheral expansion. IC Role / Device Role / Timing Role: Each 74LVC1G175DBVRG4 acts as one bit cell, capturing serial input on CLK rising edge and propagating stored value to next stage. Use Value: Enables compact, low-power shift register implementation using only six pins per stage - ideal for space-limited IoT sensor nodes and portable medical monitors. |
Use Scenario: Holding status flags (e.g., fault latch, mode select, calibration lock) in industrial PLC I/O modules where persistent state must survive brief power dips. IC Role / Device Role / Timing Role: 74LVC1G175DBVRG4 provides edge-triggered storage with hard reset via CLR, ensuring deterministic initialization on system boot or error recovery. Use Value: Guarantees glitch-free flag retention across voltage rails from 1.8 V to 5 V - eliminates need for external pull-ups or debounce circuitry. |
| Motor Control Feedback Latching | USB Hub Power Sequencing Logic |
Use Scenario: Capturing instantaneous overcurrent detection pulses from motor driver sense amplifiers and holding them until MCU service interrupt. IC Role / Device Role / Timing Role: 74LVC1G175DBVRG4 latches fast analog comparator outputs synchronized to system clock, decoupling slow firmware response from real-time fault capture. Use Value: 4.3 ns tpd ensures sub-5 ns capture window - prevents missed faults in high-speed BLDC commutation cycles. |
Use Scenario: Managing enable sequencing for multiple USB 3.0 port power switches in embedded docking stations, where strict turn-on order prevents inrush current violations. IC Role / Device Role / Timing Role: 74LVC1G175DBVRG4 stores configuration bits from host controller and releases them synchronously to downstream load switches via CLR-controlled release. Use Value: Ioff support allows safe insertion of powered dock into host - no backfeed risk when upstream VBUS is absent during hot-plug. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G74DBVR | Dual-edge-triggered D flip-flop with set/reset; no asynchronous clear; higher propagation delay (5.5 ns) | Suitable for toggle or dual-clock domain synchronization but lacks dedicated CLR for immediate reset | Select when dual-edge operation or complementary outputs are required; avoid when hard reset timing is critical |
| 74AUP1G74DBVR | Lower VCC range (0.8–3.6 V); lower ICC (0.9 µA); slower max fclock (200 MHz at 3.3 V vs. 175 MHz) | Better for ultra-low-power battery applications but incompatible with 5-V signaling or wide-voltage systems | Choose for energy-constrained wearables or sensor nodes; not suitable for mixed-voltage industrial interfaces |
Compared with SN74LVC1G74DBVR and 74AUP1G74DBVR, the 74LVC1G175DBVRG4 uniquely combines asynchronous clear, 5.5-V tolerance, and 1.65–5.5-V operation - making it the only option among the three for robust, wide-supply, reset-critical logic staging.

FAQ
What is the maximum clock frequency supported by the 74LVC1G175DBVRG4?
The 74LVC1G175DBVRG4 supports up to 175 MHz at 5 V and 150 MHz at 3.3 V over the full –40°C to 125°C operating range. These values are validated under CL = 15 pF load conditions and assume clean clock edges meeting specified rise/fall time limits. System-level timing margins must account for board trace capacitance and fanout.
Does the 74LVC1G175DBVRG4 support operation at 1.8 V?
Yes, the 74LVC1G175DBVRG4 is fully specified for 1.65-V to 5.5-V VCC operation, including reliable function at 1.8 V ± 0.15 V. At this voltage, it delivers 12.9 ns max tpd and supports 100 MHz clocking - making it suitable for low-voltage FPGA I/O banks and battery-powered microcontrollers.
How does the asynchronous clear (CLR) function behave in the 74LVC1G175DBVRG4?
In the 74LVC1G175DBVRG4, CLR is an active-low asynchronous input that forces Q low immediately upon assertion, independent of CLK state or D value. This behavior is guaranteed across all VCC levels and temperatures, with a minimum pulse width of 2.5 ns at 3.3 V - enabling precise fault latching and system initialization.
Can the 74LVC1G175DBVRG4 be used in mixed-voltage systems?
Yes, the 74LVC1G175DBVRG4 supports mixed-voltage operation via 5.5-V-tolerant inputs - allowing D and CLK to swing up to 5.5 V even when VCC = 1.65 V. This enables direct interfacing between 3.3-V microcontrollers and 5-V legacy peripherals without level shifters, provided output loading remains within ±24-mA limits.
What is the thermal resistance (RθJA) of the 74LVC1G175DBVRG4 in its SOT-23 package?
The 74LVC1G175DBVRG4 in the DBV (SOT-23) package has a junction-to-ambient thermal resistance (RθJA) of 165°C/W under standard JEDEC test conditions. This value assumes a two-layer PCB with 1 in² copper pour per side; actual thermal performance improves with additional copper area, thermal vias, or airflow.
