Product details
Overview
74AHCT14PW,112 from Nexperia is a hex inverting Schmitt trigger IC with TTL-compatible input thresholds, 14-pin TSSOP package, -40 °C to +125 °C operating range, 4.5–5.5 V supply voltage, and 9.0 ns max propagation delay at 50 pF load - used for noise-immune signal conditioning in industrial control interfaces and microcontroller reset debouncing circuits.
For engineers reviewing the 74AHCT14PW,112 datasheet, 74AHCT14PW,112 pinout, 74AHCT14PW,112 application, or 74AHCT14PW,112 equivalent, this page delivers verified functional identity, validated pin-level circuit roles, confirmed Schmitt-trigger hysteresis values (0.4–1.5 V), real-world timing specs under load, and direct substitution guidance - all grounded in Nexperia's Rev. 9 product data sheet dated 28 April 2025.
Technical Context
This device implements six independent inverting Schmitt-trigger buffers with TTL-level input compatibility (VT+ = 1.9 V, VT− = 0.5–0.6 V at VCC = 4.5–5.5 V) and rail-to-rail CMOS output drive. Its hysteresis enables reliable waveform shaping of slow or noisy digital signals without external components.
Each channel operates with balanced propagation delays (tPLH ≈ tPHL), supports overvoltage-tolerant inputs up to 5.5 V independent of VCC, and maintains stable switching thresholds across its full −40 °C to +125 °C temperature range - critical for industrial sensor interface and power-on reset generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL logic systems and robust operation under supply ripple. |
| Propagation Delay | 9.0 ns max (CL = 50 pF, VCC = 5.5 V) - guarantees sub-10 ns timing margin for high-speed debounce and clock edge cleanup. |
| Hysteresis Voltage | 0.4 V to 1.5 V (VCC = 4.5–5.5 V) - provides deterministic noise immunity against EMI-induced glitches on long traces or switch contacts. |
| Input Thresholds | VT+ = 1.9 V, VT− = 0.5 V (typ. at VCC = 4.5 V) - enables clean transition detection from standard 5 V microcontroller GPIOs or mechanical switches. |
| Output Drive | ±8 mA (VOH/VOL at VCC = 4.5 V) - sufficient to directly drive multiple 74-series inputs or small LEDs without buffering. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range embedded controllers. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces handling sensitivity and improves board-level reliability during assembly and field service. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14 leads; body width 4.4 mm; 0.65 mm lead pitch; exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | Schmitt-triggered TTL-level inputs - accept slow-rising signals and reject noise below hysteresis window. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted CMOS outputs - drive loads up to ±8 mA while maintaining rail-aligned VOH/VOL. |
| 7 | GND | Ground reference for all internal circuitry and output stage return path. |
| 14 | VCC | Main supply rail - powers all six inverters and defines output voltage swing and input threshold levels. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables direct interfacing with legacy 5 V microcontrollers and logic families without level-shifting circuitry. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - allows safe use in mixed-voltage systems where input signals exceed supply rails. |
| High noise immunity | Guaranteed 0.4–1.5 V hysteresis prevents false triggering from EMI, crosstalk, or contact bounce in harsh environments. |
| CMOS low power dissipation | ICC ≤ 40 μA at VCC = 5.5 V - minimizes quiescent current in battery-powered or thermally constrained applications. |
| Balanced propagation delays | tPLH and tPHL match within 10% - preserves pulse width integrity in timing-critical signal conditioning paths. |
Applications
| Industrial Sensor Interface | Microcontroller Reset Debouncing |
|---|---|
|
Use Scenario: Conditioning analog sensor outputs digitized via comparator stages or cleaning mechanical switch signals from limit switches and emergency stops. IC Role / Device Role / Timing Role: Schmitt-trigger inverter acting as noise-filtering buffer between noisy field wiring and clean digital input pins of PLC CPUs or motor drives. Use Value: Eliminates need for external RC filters and software debouncing, reducing BOM count and firmware complexity while ensuring deterministic response to physical events. |
Use Scenario: Generating clean, glitch-free reset pulses for ARM Cortex-M or PIC microcontrollers after power-up or manual reset button press. IC Role / Device Role / Timing Role: Inverting Schmitt trigger converting slow-rising or bouncing reset line into monotonic, fast-edge reset assertion with defined hold time. Use Value: Prevents CPU lockup or erratic boot behavior caused by marginal reset timing - meets JEDEC JESD8-12B requirements for reset pulse integrity. |
| Relaxation Oscillator | Level Translation Interface |
|
Use Scenario: Building simple, low-cost clock sources for non-critical timing functions using only one 74AHCT14PW,112, resistor, and capacitor. IC Role / Device Role / Timing Role: Inverter configured as astable multivibrator - feedback through RC network sets oscillation frequency based on VT+/VT− thresholds and propagation delay. Use Value: Delivers 1–100 kHz clock signals without crystal or dedicated oscillator IC, ideal for LED flashers, status indicators, or test pattern generators. |
Use Scenario: Interfacing 3.3 V FPGA I/O banks to 5 V peripheral buses (e.g., legacy UART modems or display controllers) where directionality is unidirectional. IC Role / Device Role / Timing Role: Level translator leveraging overvoltage-tolerant inputs - accepts 5 V signals while powered from 3.3 V, outputting compatible 3.3 V logic levels. Use Value: Avoids dedicated level-shifter ICs or resistor-divider networks, preserving signal edge rate and simplifying PCB layout for mixed-voltage subsystems. |
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 |
|---|---|---|---|
| 74AHC14PW,112 | CMOS-level inputs (VT+ = 4.4 V at VCC = 4.5 V), higher noise margin but incompatible with TTL source logic. | Requires ≥4.4 V input to register HIGH - unsuitable for 3.3 V MCU outputs or legacy 5 V TTL drivers with marginal VOH. | Select when interfacing exclusively with CMOS sources and maximum noise immunity is required over input compatibility. |
| SN74LV14APW | Lower VCC range (2.0–5.5 V), LV logic family - VOH/VOL specified at 3.3 V, weaker drive (±6 mA). | Optimized for 3.3 V systems; insufficient drive for direct 5 V bus loading or driving multiple TTL loads. | Prefer for cost-sensitive 3.3 V-only designs where 5 V tolerance and 8 mA drive are unnecessary. |
Compared with 74AHC14PW,112 and SN74LV14APW, the 74AHCT14PW,112 uniquely bridges TTL and CMOS domains with guaranteed 5 V input acceptance and robust 8 mA output drive - making it the only choice for mixed-voltage industrial I/O where legacy compatibility and noise resilience are co-required.

FAQ
Is 74AHCT14PW,112 pin-compatible with other 74-series hex inverters?
Yes - it uses the industry-standard 14-pin TSSOP footprint (SOT402-1) and identical pinout as 74HC14, 74HCT14, and 74AHC14 variants. All share the same 1A–6A inputs on odd pins (1,3,5,9,11,13), 1Y–6Y outputs on even pins (2,4,6,8,10,12), GND on pin 7, and VCC on pin 14 - enabling drop-in replacement where electrical specs align.
Can 74AHCT14PW,112 operate with a 3.3 V supply?
No - the 74AHCT14 variant is specified only for 4.5 V to 5.5 V operation per Table 5. At 3.3 V, input thresholds become undefined and output drive degrades significantly; use 74AHC14PW,112 or 74LV14APW instead for true 3.3 V compatibility.
What is the maximum capacitive load this device can drive reliably?
It is characterized up to 50 pF (Table 7), with typical tpd = 9.0 ns max at that load. Driving >50 pF increases propagation delay nonlinearly and may cause output ringing; for heavier loads, add series termination or use a buffer stage - the device's ±8 mA drive capability supports moderate fan-out but not transmission-line driving.
Does the exposed pad on the TSSOP package require grounding?
No - the thermal pad in SOT402-1 is not electrically connected (per datasheet note). It may be left floating or soldered to a thermal plane for improved heat dissipation, but must never be tied to VCC or signal nets. No electrical function is assigned to this pad.
