Product details
Overview
74LVT04DB,118 from Nexperia is a 3.3 V hex inverter IC with BiCMOS output drive, IOFF partial power-down protection, and 5.5 V-tolerant inputs. It provides six independent inverting buffers in a 14-lead SO14 package, operates from 2.7 V to 3.6 V, delivers ±32 mA output drive, and supports industrial temperature range (−40 °C to +85 °C). It is used in level-shifting interfaces between 3.3 V logic and legacy 5 V TTL buses.
For engineers reviewing the 74LVT04DB,118 datasheet, 74LVT04DB,118 pinout, 74LVT04DB,118 application, or 74LVT04DB,118 equivalent, this device is selected for robust bus interfacing where power sequencing, backflow current prevention, and mixed-voltage signal integrity are critical - especially in telecom control planes and industrial I/O modules.
Technical Context
The 74LVT04DB,118 implements six identical CMOS-input/BiCMOS-output inverter stages with active IOFF circuitry that forces outputs into high-impedance when VCC = 0 V, blocking destructive backfeed current. Each gate exhibits asymmetrical drive strength: 32 mA sink (IOL) at VOL ≤ 0.5 V and −20 mA source (IOH) at VOH ≥ 2.0 V under 3.3 V supply.
Its input structure tolerates up to 5.5 V regardless of VCC state, enabling safe connection to 5 V buses without external clamping. Propagation delays are tightly specified: tPLH/tPHL ≤ 3.9 ns/3.5 ns (max) at VCC = 3.3 V, with input transition rate support up to 10 ns/V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.7 V to 3.6 V - ensures compatibility with 3.3 V systems while accommodating rail tolerance and droop. |
| Input voltage tolerance | Up to 5.5 V - allows direct connection to 5 V TTL buses without level shifters or clamps. |
| Output drive (sink) | 32 mA at VOL ≤ 0.5 V - sufficient to drive multiple TTL loads or terminated transmission lines. |
| Output drive (source) | −20 mA at VOH ≥ 2.0 V - maintains valid HIGH logic level under capacitive or resistive loading. |
| IOFF leakage | ±100 μA at VCC = 0 V - limits backflow current during hot-swap or partial power-down sequences. |
| Propagation delay | ≤3.9 ns (L→H), ≤3.5 ns (H→L) at VCC = 3.3 V - enables timing-critical control path use up to ~100 MHz toggle rates. |
| Operating temperature | −40 °C to +85 °C - qualified for industrial ambient environments without derating. |
Pinout & Package
74LVT04DB,118 is housed in a plastic small outline package (SO14), SOT108-1, with 14 leads and 3.9 mm body width. Pin 1 is index-marked; pin 7 is GND; pin 14 is VCC; inputs occupy odd-numbered pins (1,3,5,9,11,13); outputs occupy even-numbered pins (2,4,6,8,10,12).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data input (nA) | CMOS-compatible inputs accepting 0–5.5 V; each enables one inverter stage. |
| 2, 4, 6, 8, 10, 12 | Data output (nY) | BiCMOS-driven inverted outputs; capable of sourcing/sinking full TTL load currents. |
| 7 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance return path. |
| 14 | VCC | Main supply input (2.7–3.6 V); powers internal logic and output drivers; IOFF activates when near 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF partial power-down | Disables outputs and limits backfeed current to ±100 μA when VCC = 0 V - essential for hot-plug and multi-rail systems. |
| 5.5 V-tolerant inputs | Accepts 0–5.5 V input signals irrespective of VCC state - eliminates need for external level translators in mixed-voltage designs. |
| BiCMOS output stage | Delivers 32 mA sink / −20 mA source drive with fast edge rates - drives heavy capacitive loads and TTL fanouts reliably. |
| Wide supply range | Operates from 2.7 V to 3.6 V - accommodates battery sag, LDO dropout, and board-level rail variation without functional loss. |
| Latch-up immunity | Exceeds 500 mA per JESD78 Class II Level B - ensures robustness against transient-induced latch-up in noisy industrial environments. |
Applications
| Telecom Line Card Control | Industrial PLC I/O Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APW | Lower drive (24 mA sink), no IOFF, 3.6 V max VCC, same SO14 package. | Lacks partial power-down protection; unsuitable for hot-swap or multi-rail sequencing. | Select when IOFF is unnecessary and cost sensitivity outweighs robustness requirements. |
| 74ALVC04PW | Higher speed (tPD ≤ 2.5 ns), lower drive (24 mA), no IOFF, 3.6 V max VCC, TSSOP14 only. | Not pin-compatible with SO14; lacks 5.5 V input tolerance and IOFF - requires external clamping for 5 V bus ties. | Choose only for speed-critical, single-rail 3.3 V systems where package change is acceptable. |
Compared with SN74LVC04APW and 74ALVC04PW, the 74LVT04DB,118 uniquely combines 5.5 V input tolerance, IOFF protection, and 32 mA drive in SO14 - making it the sole option for industrial hot-swap interfaces requiring both robustness and legacy bus compatibility.

FAQ
Does 74LVT04DB,118 support hot-swap insertion into a live 5 V bus?
Yes - its IOFF circuitry disables outputs and limits backfeed current to ±100 μA when VCC = 0 V, and its inputs tolerate up to 5.5 V regardless of supply state. This allows safe insertion into powered 5 V systems without damaging upstream drivers or downstream logic.
Can 74LVT04DB,118 drive standard TTL loads directly?
Yes - with 32 mA sink and −20 mA source capability at VCC = 3.3 V, it meets or exceeds standard TTL input current requirements (IIL = −1.6 mA, IIH = 40 μA) and can drive up to 10 LS-TTL loads per output without external buffers.
What is the maximum capacitive load the output can drive while maintaining timing specs?
Per the datasheet test conditions (CL = 50 pF, RL = 500 Ω), propagation delay remains within spec (≤3.9 ns) up to 50 pF. For higher capacitance, delay increases linearly; at 100 pF, typical tPLH rises to ~5.2 ns - still usable in non-critical paths with margin analysis.
Is 74LVT04DB,118 qualified for automotive applications?
No - it is explicitly rated for industrial temperature range (−40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia's documentation states non-automotive qualified products are not tested to automotive reliability or stress standards and must not be used in safety-critical vehicle systems.
