Product details
Overview
74LVC14APW/S505118 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 6.4 ns max propagation delay at 3.6 V and ±24 mA output drive, used for noise-immune signal conditioning in mixed-voltage digital interfaces.
For engineers reviewing the 74LVC14APW/S505118 datasheet, 74LVC14APW/S505118 pinout, 74LVC14APW/S505118 application, or 74LVC14APW/S505118 equivalent, this page delivers verified package mapping (TSSOP14), Schmitt-trigger hysteresis values (0.3–1.2 V), input overvoltage tolerance (5.5 V), static/dynamic electrical specs, and two validated alternative parts for voltage-level translation and waveform shaping use cases.
Technical Context
The 74LVC14APW/S505118 implements six independent CMOS inverting Schmitt triggers with asymmetric input thresholds (VT+ = 1.2–2.0 V, VT− = 0.3–1.5 V at VCC = 3.6 V) and 0.3–1.2 V hysteresis, enabling robust noise rejection in slow-rising or noisy signals. Its 5.5 V tolerant inputs allow direct interfacing between 3.3 V logic and legacy 5 V systems without external level shifters.
Each buffer supports rail-to-rail output swing, operates across −40 °C to +125 °C, and exhibits low static current (≤40 μA at VCC = 3.6 V) and dynamic power dissipation governed by CPD = 15.6 pF - critical for battery-powered and thermally constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - enables operation in ultra-low-power and dual-rail 1.8 V/2.5 V/3.3 V systems |
| Input Voltage Tolerance | Up to 5.5 V - allows safe connection to 5 V sources without clamping diodes or external protection |
| Propagation Delay | 6.4 ns max at VCC = 3.6 V - supports >100 MHz signal edge conditioning in timing-critical paths |
| Hysteresis Voltage | 0.3 V to 1.2 V (VCC = 1.2 V to 3.6 V) - provides configurable noise immunity for varying signal slew rates |
| Output Drive | ±24 mA at VCC = 3.0 V - drives standard TTL loads and moderate capacitive bus lines directly |
| Operating Temperature | −40 °C to +125 °C - qualified for industrial and extended-temperature embedded control environments |
| ESD Protection | HBM >2000 V, CDM >1000 V - ensures robust handling during PCB assembly and field service |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm pitch, 1.20 mm max height - optimized for high-density PCB layouts with thermal enhancement via exposed pad (non-soldered or GND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | Schmitt-trigger inputs accepting 0–5.5 V; enable noise-immune signal acquisition from sensors or legacy buses |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted CMOS outputs with rail-to-rail swing; drive downstream logic or RC oscillators |

Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.2 V to 3.6 V operation supports compatibility with modern low-voltage microcontrollers and FPGAs |
| 5 V Tolerant Inputs | Inputs withstand 5.5 V regardless of VCC - eliminates need for external level translators in mixed-voltage systems |
| Schmitt-Trigger Hysteresis | Configurable VT+ and VT− thresholds provide ≥0.3 V noise margin - prevents chatter on slow or noisy signals |
| Unlimited Input Slew Rate | No minimum rise/fall time requirement - accepts arbitrarily slow analog-like transitions (e.g., thermistor outputs) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC14APWR | TI part in TSSOP14; identical VCC range (1.65–3.6 V), but VT+ = 1.5 V min and VT− = 0.5 V max at 3.3 V - narrower hysteresis than 74LVC14APW/S505118 | Less noise margin on marginal signals; suitable where tighter threshold control is preferred over maximum immunity | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation |
| 74AHC14PW | Nexperia AHC variant in same TSSOP14; wider VCC range (2.0–5.5 V), higher drive (±8 mA), but no 5 V input tolerance - requires VCC ≥ input voltage | Not usable for 5 V → 3.3 V level translation; better for pure 5 V or 3.3 V systems needing faster tpd (5.5 ns typ) | Choose for higher-speed designs where input voltage never exceeds VCC and 5 V tolerance is unnecessary |
Compared with SN74LVC14APWR and 74AHC14PW, the 74LVC14APW/S505118 uniquely combines 1.2 V minimum supply, 5.5 V input tolerance, and guaranteed hysteresis down to 0.3 V - making it optimal for ultra-low-voltage mixed-signal interfacing where noise immunity and voltage translation coexist.

FAQ
What is the maximum input voltage rating for the 74LVC14APW/S505118?
The 74LVC14APW/S505118 supports input voltages up to 5.5 V regardless of supply voltage - a key feature enabling direct interface with 5 V sources while operating from as low as 1.2 V. This overvoltage tolerance is specified in Table 4 (Limiting Values) and confirmed across all temperature ranges.
Does the 74LVC14APW/S505118 require external pull-up resistors on its inputs?
No, the 74LVC14APW/S505118 does not require external pull-up resistors. Its CMOS inputs have negligible leakage (±20 μA max), and Schmitt-trigger thresholds are internally defined. Pull-ups are only needed if the driving source is open-drain or high-impedance - not inherent to the 74LVC14APW/S505118's operation.
Can the 74LVC14APW/S505118 operate at 1.2 V supply and still meet timing specifications?
Yes, the 74LVC14APW/S505118 is fully characterized down to 1.2 V: propagation delay is 16 ns max at that voltage (Table 7), and static parameters including VOH/VOL and hysteresis remain valid per Tables 6 and 9 - ensuring functional reliability in ultra-low-power designs.
What is the thermal performance of the TSSOP14 package used by the 74LVC14APW/S505118?
The TSSOP14 (SOT402-1) package of the 74LVC14APW/S505118 has a power dissipation limit of 500 mW below 81 °C, derating linearly at 7.3 mW/K above that temperature (Table 4). Its exposed pad improves thermal resistance, supporting continuous operation in industrial ambient conditions up to +125 °C.
How many independent Schmitt-trigger inverters are integrated in the 74LVC14APW/S505118?
The 74LVC14APW/S505118 integrates six fully independent inverting Schmitt triggers (labeled 1A/1Y through 6A/6Y), each with identical electrical characteristics and no shared internal nodes - allowing concurrent use for multi-channel signal conditioning without crosstalk or timing interaction.
