Product details
Overview
74LVC1G04SE-7 from Diodes Incorporated is a single CMOS inverter gate with push-pull output, designed for 1.65V–5.5V supply operation and 5.5V-tolerant inputs. It delivers ±24mA output drive at 3.3V, supports partial power-down via IOFF, and is qualified for voltage level shifting and logic isolation in portable electronics.
For engineers reviewing the 74LVC1G04SE-7 datasheet, 74LVC1G04SE-7 pinout, 74LVC1G04SE-7 application, or 74LVC1G04SE-7 equivalent, key selection criteria include supply voltage range, IOFF leakage (<±10μA), propagation delay (0.5–5.5ns at 3.3V), input tolerance (5.5V), and SOT353 package thermal resistance (371°C/W).
Technical Context
This device implements a single positive-logic inverter (Y = A̅) with rail-to-rail CMOS output swing and TTL-level input compatibility. Its IOFF circuit actively disables output during power-down to prevent backflow current, enabling safe use in mixed-voltage, hot-swap, or partial-power-down systems.
It operates across industrial temperature (–40°C to +125°C) with guaranteed switching performance down to 1.65V supply, and features ESD protection exceeding 2kV HBM, 1kV CDM, and 200V MM - critical for handheld and peripheral interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct interface between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage buses while powered from lower VCC (e.g., 1.8V). |
| IOFF Leakage Current | ±10μA max at 0V VCC - ensures negligible backfeed current during system sleep or power sequencing. |
| Propagation Delay | 0.5ns min / 5.5ns max at 3.3V - supports >100MHz toggle rates in low-latency signal inversion paths. |
| Output Drive Strength | ±24mA at 3.3V - sufficient to drive multiple LVC inputs or small capacitive loads (≤30pF) without buffering. |
| ESD Protection | 2kV HBM, 1kV CDM, 200V MM - exceeds JEDEC standards for robustness in consumer assembly and field environments. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive peripherals and industrial control logic interfaces. |
Pinout & Package
SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm lead pitch) - ultra-compact 5-pin package with exposed pad option for thermal enhancement in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | Active-high logic input; accepts 0–5.5V regardless of VCC; internally pulled neither high nor low. |
| 2 (GND) | Ground Reference | Primary return path for output current and internal bias; must be low-impedance for noise immunity. |
| 3 (Y) | Output | Inverted logic output with full rail-to-rail swing; capable of sourcing/sinking ±24mA at 3.3V. |
| 4 (VCC) | Power Supply | Core supply input (1.65–5.5V); powers internal logic and output stage; bypass capacitor required. |
| 5 (NC) | No Connection | Internally unconnected pin; must remain floating or grounded per layout guidelines - no external tie. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65V–5.5V operation enables drop-in replacement across legacy and modern low-voltage systems. |
| IOFF Partial Power-Down | Automatically disables output when VCC = 0V, preventing bus contention and backdrive damage in multi-rail designs. |
| 5.5V-Tolerant Inputs | Allows direct interfacing with 5V signals while operating from 1.8V/2.5V supplies - eliminates external level translators. |
| Low Dynamic Power | Typical ICC = 0.1μA at 3.3V - reduces quiescent current in always-on logic monitoring circuits. |
| Small-Signal Speed | tpd ≤ 5.5ns at 3.3V - supports clean inversion of clock enables, reset signals, and status flags up to ~180MHz. |
Applications
| USB Device Enumeration Control | SD Card Interface Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Texas Instruments variant in SOT-23-5 (same pinout); slightly higher typical ICC (1μA vs. 0.1μA) and lower ESD rating (1.5kV HBM). | Less suitable for ultra-low-power battery-backed systems requiring sub-100nA standby current. | Prefer when TI ecosystem alignment or existing SOT-23 footprint reuse is prioritized over lowest leakage. |
| 74AUP1G04GW,125 | Nexperia AUP family; lower VCC range (0.8–3.6V), 1.8V optimized; 3.5ns max tpd at 1.8V but not 5.5V tolerant. | Cannot interface with 5V signals - requires additional clamping or level translation in mixed-voltage systems. | Choose only for pure 1.8V subsystems where minimum dynamic power (0.9μA ICC) and speed at low voltage outweigh input flexibility. |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the 74LVC1G04SE-7 uniquely balances wide voltage operation (1.65–5.5V), 5.5V input tolerance, ultra-low IOFF leakage (±10μA), and SOT353's 2.0×2.0mm footprint - making it optimal for portable, multi-rail, and space-constrained logic inversion tasks.

FAQ
Can 74LVC1G04SE-7 operate reliably at 1.65V supply?
Yes. The device is fully characterized from 1.65V to 5.5V, with guaranteed propagation delay ≤7.5ns and output drive ≥±4mA at 1.65V. Input thresholds scale with VCC (VIH = 0.65×VCC), ensuring noise margin compliance across the entire range.
Is the NC pin on SOT353 package required to be grounded?
No. Pin 5 is internally unconnected and must remain floating or optionally tied to GND for mechanical stability - never connected to VCC or driven. Diodes Incorporated's recommended layout shows it as non-bonded; grounding does not affect electrical performance.
Does 74LVC1G04SE-7 support hot insertion into a live 3.3V bus?
Yes, when used with IOFF enabled (VCC = 0V). With VCC unpowered, IOFF limits output leakage to ±10μA, preventing disruptive current injection into the live bus. However, input must not exceed 5.5V during insertion, and VCC ramp rate should follow manufacturer-recommended sequencing.
What is the maximum capacitive load this inverter can drive at 3.3V without signal degradation?
At 3.3V, the device maintains ≤5.5ns propagation delay and monotonic edges up to 30pF load (per datasheet test condition). For loads >30pF, edge rate degrades linearly - e.g., 50pF increases tpd to ~7ns and may require series termination to suppress ringing in high-speed traces.
