Product details
Overview
74LV04AS14-13 from Diodes Incorporated is a hex inverter IC with six independent CMOS push-pull inverters, operating across 2.0V–5.5V supply, featuring 5.5V-tolerant inputs, IOFF partial-power-down protection, and Schmitt-trigger inputs. It delivers 12mA output drive at 4.5V and supports voltage translation between 3.3V and 5V logic domains in mixed-supply systems.
For engineers reviewing the 74LV04AS14-13 datasheet, 74LV04AS14-13 pinout, 74LV04AS14-13 application, or 74LV04AS14-13 equivalent, key selection criteria include propagation delay (≤5.5ns @5V), IOFF leakage (<5μA), input voltage tolerance (up to 5.5V), and SO-14 package compatibility with legacy PCB footprints.
Technical Context
The 74LV04AS14-13 implements standard Boolean inversion (Y = A̅) with Schmitt-trigger inputs enabling noise immunity on slow or noisy signals. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow when VCC = 0V while inputs remain biased at up to 5.5V.
Designed for mixed-voltage interfacing, it accepts 3.3V or 5V inputs regardless of VCC setting (2.0V–5.5V), and maintains guaranteed VOH/VOL levels across temperature (–40°C to +125°C) and load (CL = 15pF/50pF). Propagation delay scales inversely with supply voltage: 5.5ns typ @5V, 7.1ns @2.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0V to 5.5V - enables direct use in 3.3V and 5V systems without level shifters |
| Input Voltage Tolerance | Up to 5.5V - allows safe interfacing with higher-voltage controllers even when VCC = 2.0V |
| IOFF Leakage Current | <5 μA - prevents damaging backflow during partial power-down in hot-swap or sleep-mode designs |
| Output Drive (IOL/IOH) | ±12 mA @ VCC = 4.5V - sufficient to drive multiple 74-series inputs or small capacitive loads |
| Propagation Delay | 3.6 ns (typ) @ VCC = 5.0V, CL = 15pF - supports >100 MHz toggle rates in low-load logic paths |
| Input Hysteresis | Schmitt-trigger action - provides ~0.3V–0.5V hysteresis, rejecting noise on slow-rising control lines |
| ESD Protection | 2 kV HBM, 1 kV CDM - exceeds JEDEC JESD22-A114/A101 requirements for board-level robustness |
Pinout & Package
74LV04AS14-13 is housed in a 14-pin SOIC (SO-14) package per JEDEC MS-012, with 1.27 mm pitch, 8.53–8.74 mm body width, and 3.80–3.99 mm body length. Pin 1 is marked by a notch or dot; GND (Pin 7) and VCC (Pin 14) are centrally located for optimal decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | CMOS Schmitt-trigger inputs accepting 0–5.5V; unused pins must be tied to VCC or GND |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Push-pull CMOS outputs sourcing/sinking up to ±12 mA; support rail-to-rail swing |
| 7 | GND | Ground reference for all logic and power domains; requires low-inductance connection to PCB ground plane |
| 14 | VCC | Primary supply input (2.0–5.5V); requires local 100nF ceramic decoupling placed ≤5 mm from pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range (2.0–5.5V) | Eliminates need for separate LDOs in multi-rail systems; supports battery-powered 3.3V and legacy 5V designs |
| IOFF Partial Power-Down | Enables safe insertion/removal in live backplanes or modular systems where VCC may be unpowered while bus remains active |
| 5.5V-Tolerant Inputs | Permits direct connection to 5V microcontrollers or FPGAs without external resistors or translators when VCC = 3.3V |
| Schmitt-Trigger Inputs | Rejects <100 mV noise on reset, enable, or interrupt lines; eliminates need for external RC filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV04APW | TSSOP-14 package; identical electrical specs but 0.65 mm pitch vs SO-14's 1.27 mm | Better suited for space-constrained PCBs; requires rework of land pattern and stencil | Select when board area is limited and assembly process supports fine-pitch SMT |
| 74LVC04PW | Lower max VCC (3.6V); no 5.5V input tolerance; 24mA drive @3.3V | Not suitable for 5V-tolerant mixed-voltage interfaces; higher drive but narrower supply range | Choose only if system operates strictly at 3.3V and requires stronger output current |
Compared with SN74LV04APW and 74LVC04PW, the 74LV04AS14-13 uniquely balances 5.5V input tolerance, SO-14 footprint compatibility, and industrial temperature support (–40°C to +125°C), making it optimal for legacy-replacement and mixed-rail embedded control.

FAQ
Can 74LV04AS14-13 be used with a 2.0V supply and 5V input signals?
Yes. The device guarantees 5.5V input tolerance across its full 2.0V–5.5V supply range. At VCC = 2.0V, inputs up to 5V are safely clamped and interpreted correctly per VIH/VIL thresholds defined in the datasheet, enabling robust level translation without external components.
What is the maximum capacitive load this inverter can drive reliably?
It drives up to 50 pF with guaranteed timing (tPD ≤ 7.5 ns @5V), as validated in switching characteristics tables. For loads exceeding 50 pF, propagation delay increases linearly; design margin should include derating for worst-case temperature and voltage to maintain setup/hold timing in synchronous logic paths.
Does the IOFF feature require external circuitry to activate?
No. IOFF is fully internal and automatic: when VCC drops below ~0.8V, the output transistors are disabled regardless of input state or voltage. No enable pin, bias resistor, or external control is needed-this behavior is inherent to the silicon design and verified per JESD78 latch-up testing.
Is the SO-14 package RoHS-compliant and lead-free?
Yes. The 74LV04AS14-13 uses a fully lead-free SO-14 package compliant with EU RoHS Directive 2011/65/EU, containing no intentionally added lead, halogen, or antimony compounds. Full compliance documentation and material declarations are available via Diodes Incorporated's product portal.
