Product details
Overview
74LVC14AD,112 from Nexperia is a hex inverting Schmitt trigger IC with 5 V tolerant inputs, operating from 1.2 V to 3.6 V supply, delivering hysteresis-based noise immunity and level translation between 3.3 V and 5 V logic domains in industrial control signal conditioning circuits.
For engineers reviewing the 74LVC14AD,112 datasheet, 74LVC14AD,112 pinout, 74LVC14AD,112 application, or 74LVC14AD,112 equivalent, key selection factors include input hysteresis voltage (0.3–1.2 V), propagation delay (1.0–8.0 ns), 5.5 V overvoltage-tolerant inputs, -40 °C to +125 °C operation, and SO14 package compatibility with legacy 74-series footprints.
Technical Context
The 74LVC14AD implements six independent CMOS Schmitt-trigger inverters with asymmetric threshold voltages (VT+ = 0.4–2.0 V, VT− = 0.12–1.5 V) enabling reliable waveform shaping in noisy environments. Each buffer provides rail-to-rail output swing and supports unlimited input rise/fall times.
Its design integrates ESD protection per JS-001 (HBM >2000 V) and JS-002 (CDM >1000 V), complies with JEDEC JESD8-C/JESD36 for 2.7–3.6 V operation, and maintains stable timing across full temperature range without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct integration into low-voltage microcontroller I/O domains while maintaining compatibility with 3.3 V systems. |
| Input Overvoltage Tolerance | Up to 5.5 V - Allows safe interfacing with 5 V legacy peripherals without level-shifter circuitry. |
| Hysteresis Voltage (VH) | 0.3 V to 1.2 V - Provides robust noise margin against EMI in industrial sensor signal paths. |
| Propagation Delay (tpd) | 1.0 ns (min) to 8.0 ns (max) at VCC = 3.0–3.6 V - Supports high-speed pulse reshaping up to ~125 MHz edge rates. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple 74LVC inputs or small capacitive loads (≤50 pF). |
| Static Supply Current | 0.1 μA typical, ≤40 μA max - Enables ultra-low-power operation in battery-backed monitoring nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV14APWRE4 | TI part; identical SO14 pinout; wider VCC range (1.65–5.5 V); higher ICC (10 μA typ vs. 0.1 μA) | Supports 5 V-only systems but consumes ~100× more quiescent current in sleep mode | Select when 5 V native operation is required and low power is secondary |
| 74AHC14PW,118 | Nexperia AHC variant; same SO14 package; higher VCC (2–5.5 V); faster tpd (2.5 ns typ @ 5 V) but no 5 V input tolerance | Not suitable for mixed 3.3/5 V translation; requires external clamping for 5 V inputs | Select only in pure 5 V systems where speed >300 MHz edge rates is critical |
Compared with SN74LV14APWRE4 and 74AHC14PW,118, the 74LVC14AD,112 uniquely balances 5 V input tolerance, ultra-low ICC, and industrial temperature support-making it optimal for battery-powered or thermally constrained mixed-voltage signal conditioning.

FAQ
What is the maximum input voltage the 74LVC14AD,112 can safely accept?
The 74LVC14AD,112 accepts input voltages up to 5.5 V DC regardless of VCC level, as confirmed in Table 4 (Limiting Values) and Section 1 (General Description). This overvoltage tolerance applies to all six inputs (1A–6A) and enables direct interfacing with 5 V logic without external protection components.
Can the 74LVC14AD,112 operate at 1.8 V supply and still drive standard LVC loads?
Yes. At VCC = 1.8 V, the device delivers VOH ≥ 1.65 V and VOL ≤ 0.45 V (Table 6), meeting LVC family thresholds. Its ±8 mA drive strength at this voltage ensures fanout of ≥10 LVC inputs while maintaining noise margins above 0.4 V.
Does the SO14 package (SOT108-1) have an exposed thermal pad?
No. The SO14 package used for 74LVC14AD,112 (SOT108-1) has no exposed thermal pad. Pin 7 is GND and pin 14 is VCC; the package relies on lead-frame conduction for thermal dissipation, with Ptot = 500 mW at Tamb ≤100 °C (Table 4, note [3]).
How does the hysteresis voltage vary with supply voltage?
Hysteresis (VH = VT+ − VT−) ranges from 0.1 V to 1.2 V depending on VCC, per Table 9. At VCC = 3.6 V, VH is 0.3–1.2 V; at VCC = 1.2 V, it narrows to 0.1–1.0 V. This scaling ensures consistent noise margin relative to supply rails across the full operating range.
