Product details
Overview
SN74LVC1G04DBVTG4 from Texas Instruments is a single CMOS inverter gate operating from 1.65V to 5.5V VCC, delivering 24mA output drive at 3.3V, with 3.3ns max propagation delay and 10μA max ICC. It features 5.5V-tolerant inputs for voltage-level translation and Ioff support for live-insertion and partial-power-down protection. Used in portable audio, SSDs, and embedded PCs for signal inversion and level-shifting.
For engineers reviewing the SN74LVC1G04DBVTG4 datasheet, SN74LVC1G04DBVTG4 pinout, SN74LVC1G04DBVTG4 application, or SN74LVC1G04DBVTG4 equivalent, key selection criteria include its SOT-23-5 (DBV) package, 5.5V input tolerance, Ioff functionality, ±24mA drive strength at 3.3V, and operation across –40°C to 125°C.
Technical Context
The SN74LVC1G04DBVTG4 implements the Boolean function Y = A using a standard CMOS inverter topology with balanced high/low output drive. Its design supports mixed-voltage system interfacing via 5.5V-tolerant inputs while powered from as low as 1.65V, enabling down-translation without external level shifters.
Ioff circuitry actively disables outputs when VCC = 0V, preventing back-drive current and enabling hot-plug capability. The device meets JESD 78 Class II latch-up immunity (>100mA) and exceeds JESD 22 ESD ratings: ±2000V HBM, ±1000V CDM, and ±200V MM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| tpd (max) | 3.3ns at 3.3V, CL = 15pF - supports >100MHz signal inversion in low-capacitance paths |

| 2 | Input (A) | Inverting logic input - accepts 0V to 5.5V; threshold centered at ~VCC/2 |
| 3 | GND | Ground reference - requires low-inductance connection to system ground plane |
| 4 | Output (Y) | Inverted logic output - drives complementary signal with rail-to-rail swing (0V to VCC) |
| 5 | VCC | Power supply - bypass with 0.1μF ceramic capacitor placed within 2mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| 5.5V Input Tolerance | Enables direct interface with 5V microcontrollers while operating from 1.8V or 3.3V rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Same DBV package, 3000-unit tape-and-reel vs. 250-unit for DBVTG4; identical electrical specs and marking | Better suited for high-volume automated assembly; same thermal and reliability profile | Select DBVR for production runs; DBVTG4 preferred for prototyping and low-MOQ procurement |
| 74LVC1G04GW,125 | NXP SC-70-5 package (DCK), 2.0mm × 2.1mm body; same VCC range and Ioff, but 3.7ns max tpd at 3.3V | Smaller footprint than DBV, but lower drive (±24mA only at VCC ≥ 3.0V) and reduced thermal performance (RθJA = 371°C/W) | Choose GW for space-constrained designs where 0.7mm² area saving outweighs 0.4ns tpd penalty and thermal derating needs |
Compared with SN74LVC1G04DBVR and 74LVC1G04GW,125, the SN74LVC1G04DBVTG4 offers optimal balance of manufacturability (SOT-23-5), thermal performance (RθJA = 357°C/W), and low-MOQ availability - making it ideal for engineering validation and low-volume embedded deployments requiring guaranteed Ioff and 5.5V input tolerance.

FAQ
What is the maximum operating temperature for SN74LVC1G04DBVTG4?
The SN74LVC1G04DBVTG4 is rated for operation from –40°C to +125°C ambient temperature. This extended range is validated per JEDEC JESD22-A104 and supports use in industrial power supplies, SSDs, and automotive infotainment systems where thermal margins are critical. Derating is not required up to 125°C under recommended operating conditions.
Does SN74LVC1G04DBVTG4 support 5V input signals when powered from 3.3V?
Yes, SN74LVC1G04DBVTG4 supports input voltages up to 5.5V independent of VCC, enabling direct interfacing with 5V microcontrollers or legacy peripherals while operating from a 3.3V supply. This down-translation capability eliminates external level shifters in mixed-voltage designs.
What is the purpose of the NC pin on SN74LVC1G04DBVTG4?
Pin 1 of SN74LVC1G04DBVTG4 is a no-connect (NC) terminal with no internal bond wire or silicon connection. It must remain unconnected - neither tied to GND nor VCC - to avoid unintended coupling or mechanical stress on the die. TI's layout guidelines explicitly prohibit routing or soldering to this pin.
How does Ioff functionality benefit system design with SN74LVC1G04DBVTG4?
Ioff in SN74LVC1G04DBVTG4 disables output drivers when VCC = 0V, limiting Ioff current to ±10μA max. This prevents back-driving powered sections of a board during hot-swap, partial power-down, or modular subsystem replacement - protecting upstream drivers and ensuring system-level fault containment.
What bypass capacitor value is recommended for SN74LVC1G04DBVTG4?
A 0.1μF X7R ceramic capacitor is recommended for SN74LVC1G04DBVTG4, placed within 2mm of the VCC pin and connected directly to the GND pin using short, low-inductance traces. This provides effective high-frequency decoupling for switching transients and maintains stable VCC during output transitions.
