Product details
Overview
SN74LVC1GU04DBVR from Texas Instruments is a single unbuffered CMOS inverter gate operating from 1.65 V to 5.5 V, delivering ±24 mA output drive at 3.3 V, with 3.7 ns maximum propagation delay and 10 µA maximum ICC. It performs Y = A logic inversion and is used in oscillator circuits, level translation, and signal conditioning in portable media players and embedded PCs.
For engineers reviewing the SN74LVC1GU04DBVR datasheet, SN74LVC1GU04DBVR pinout, SN74LVC1GU04DBVR application, or SN74LVC1GU04DBVR equivalent, key selection criteria include unbuffered output architecture for stable oscillation, Ioff support for live insertion, overvoltage-tolerant inputs up to 5.5 V, and NanoFree™ SOT-23 (DBV) packaging for space-constrained PCB layouts.
Technical Context
The SN74LVC1GU04DBVR implements a single-stage unbuffered inverter using standard CMOS technology, eliminating input/output buffering stages to reduce gain sensitivity-critical for reliable RC and crystal oscillator design. Its balanced push-pull output delivers matched sourcing and sinking capability (±24 mA at 3.3 V), enabling fast edge rates into light capacitive loads.
It features Ioff circuitry that disables input/output leakage when VCC = 0 V, supporting partial power-down modes and back-drive protection. Inputs tolerate voltages up to 5.5 V independent of VCC, and negative clamping diodes protect against transient undershoot per JESD 22 specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-voltage interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tpd (max) | 3.7 ns at 3.3 V - enables high-speed signal inversion in timing-critical paths without added latency |
| Output Drive | ±24 mA at 3.3 V - sufficient to directly drive LEDs, small MOSFET gates, or multiple LVC inputs |
| Ioff Support | Active at VCC = 0 V - prevents current backflow during hot-plug or partial power-down sequences |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Buffered output stage; 4.5 ns max tpd at 3.3 V; identical VCC range and Ioff support | Higher gain and phase margin make it less suitable for oscillator circuits but more noise-immune in noisy digital environments | Choose SN74LVC1G04DBVR when signal integrity in electrically noisy systems outweighs oscillator stability needs |
| 74AUP1G04GW,125 | Lower ICC (0.9 µA typ), slower tpd (10.5 ns max at 3.0 V), 0.8–3.6 V VCC range; no overvoltage-tolerant inputs | Better suited for ultra-low-power always-on monitoring circuits, not for 5 V interface or oscillator use | Choose 74AUP1G04GW,125 only for sub-1 µA standby applications where speed and voltage tolerance are secondary |
Compared with SN74LVC1GU04DBVR, SN74LVC1G04DBVR offers improved noise immunity but sacrifices oscillator suitability due to buffering, while 74AUP1G04GW,125 trades speed and voltage range for extreme low-power operation-neither is pin-compatible nor drop-in; layout and firmware validation required for substitution.

FAQ
What is the primary function of the SN74LVC1GU04DBVR?
The SN74LVC1GU04DBVR is a single unbuffered CMOS inverter performing Boolean logic Y = A. Its unbuffered architecture provides lower gain and reduced phase shift compared to buffered equivalents, making it especially suitable for oscillator circuits, signal inversion, and level translation in portable and embedded systems. The SN74LVC1GU04DBVR operates across 1.65 V to 5.5 V and supports Ioff for partial power-down.
Does the SN74LVC1GU04DBVR support 5-V operation?
Yes, the SN74LVC1GU04DBVR supports VCC operation up to 5.5 V and accepts input voltages up to 5.5 V regardless of supply voltage-enabling safe interfacing with 5 V peripherals even when powered from 3.3 V or lower. This overvoltage tolerance eliminates external level-shifting components in mixed-voltage designs using the SN74LVC1GU04DBVR.
What package type does the SN74LVC1GU04DBVR use?
The SN74LVC1GU04DBVR uses the SOT-23 (DBV) package: a 5-pin, surface-mount, NanoFree™ construction with nominal dimensions of 2.90 mm × 1.60 mm. This die-as-package format minimizes footprint and thermal resistance (RθJA = 231.5°C/W), supporting high-density PCB layouts typical in portable media players and embedded PCs where the SN74LVC1GU04DBVR is deployed.
Can the SN74LVC1GU04DBVR be used in oscillator circuits?
Yes-the SN74LVC1GU04DBVR is explicitly designed for oscillator applications due to its unbuffered output, which provides lower gain and greater stability in RC and crystal-based feedback loops. TI's application report "Use of the CMOS Unbuffered Inverter in Oscillator Circuits" details implementation methods. The SN74LVC1GU04DBVR's predictable propagation delay and low ICC make it ideal for low-jitter, low-power timing generation.
What is the maximum output drive capability of the SN74LVC1GU04DBVR?
The SN74LVC1GU04DBVR delivers ±24 mA output drive at VCC = 3.3 V, with scalable current down to ±4 mA at 1.65 V. This high-drive capability allows direct interfacing with LEDs, small-signal MOSFET gates, and multiple LVC-series logic inputs without external buffers. The SN74LVC1GU04DBVR maintains this performance across –40°C to +125°C, supporting industrial and automotive-adjacent applications.
