Product details
Overview
74HCT2G14GV,125 from Nexperia is a dual inverting Schmitt trigger IC with TTL-compatible inputs, 6-pin SC-74 (SOT457) package, -40 °C to +125 °C operating range, 4.5–5.5 V supply, and 0.4 V typical low-level output voltage at 4 mA load - used for noise-immune signal conditioning in industrial sensor interfaces and oscillator circuits.
For engineers reviewing the 74HCT2G14GV,125 datasheet, 74HCT2G14GV,125 pinout, 74HCT2G14GV,125 application, or 74HCT2G14GV,125 equivalent, this page delivers verified electrical behavior, validated pin functions, confirmed Schmitt threshold hysteresis (0.4–0.71 V), real-world timing specs (tpd = 21–48 ns), and direct substitution guidance - all extracted from Nexperia's Rev. 4 product data sheet dated 4 December 2023.
Technical Context
The 74HCT2G14GV,125 implements two independent inverting Schmitt triggers with TTL-level input thresholds (VT+ = 1.2–1.9 V, VT− = 0.5–1.4 V at VCC = 4.5–5.5 V) and hysteresis (VH = 0.4–0.71 V), enabling clean digital conversion of slow or noisy analog waveforms without external components.
Its CMOS output stage delivers rail-to-rail switching (VOH ≥ 4.13 V, VOL ≤ 0.4 V at 4 mA), supports unlimited input rise/fall times, and maintains stable propagation delay (21–48 ns) across full temperature and supply ranges - critical for relaxation oscillators and pulse shaping in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and robust operation under supply ripple. |
| Input Thresholds | VT+ = 1.2–1.9 V, VT− = 0.5–1.4 V - provides 0.4–0.71 V hysteresis for reliable noise rejection on slow-rising signals. |
| Propagation Delay | 21–48 ns (CL = 50 pF) - guarantees predictable timing in monostable/multivibrator designs across -40 °C to +125 °C. |
| Output Drive | ±4.0 mA - sufficient to directly drive LEDs, small logic loads, or RC oscillator networks without buffering. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded control. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - enables safe handling and board-level integration without additional protection circuitry. |
| Power Dissipation | 250 mW max (derated above 89 °C) - supports continuous operation in compact, thermally constrained PCB layouts. |
Pinout & Package
74HCT2G14GV,125 uses the SC-74 (SOT457) plastic surface-mounted package: 6-lead, 1.7 mm body width, 0.65 mm lead pitch, and pin 1 indicator located below the marking code "T14" in the lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A | First Schmitt-trigger input; accepts TTL-level signals (0.8 V/2.0 V thresholds) with clamp diodes for overvoltage tolerance. |
| GND | Ground | Reference node for all input/output voltages and supply return path; must be low-impedance for noise immunity. |
| 2A | Input B | Second independent Schmitt-trigger input; electrically isolated from 1A with identical threshold behavior. |
| 2Y | Output B | Inverted, jitter-free output corresponding to 2A; drives capacitive loads up to 50 pF with controlled transition time (6–22 ns). |
| VCC | Supply | Positive supply terminal; requires local 100 nF decoupling near pin 5 to suppress switching noise coupling. |
| 1Y | Output A | Inverted, jitter-free output corresponding to 1A; shares same output structure and drive capability as 2Y. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input levels | Validates operation with legacy 5 V microcontroller GPIO, FPGA I/O banks, and industrial PLC outputs without level shifters. |
| Unlimited input rise/fall times | Enables direct use with RC-generated ramps, thermistor-based slow sensors, or mechanical switch debouncing without timing constraints. |
| Balanced propagation delays | Ensures matched timing between both channels - essential for symmetrical astable multivibrators and dual-edge triggered circuits. |
| Clamp diodes on inputs | Permits use of series current-limiting resistors to interface to voltages exceeding VCC (e.g., 12 V sensor lines) without damage. |
| Latch-up immunity >100 mA | Guarantees robustness against transient overcurrent events per JESD78 Class II Level B - critical for field-deployed equipment. |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
|
Use Scenario: Converting noisy, slowly varying analog sensor outputs (e.g., thermistor or potentiometer wipers) into clean square waves for microcontroller edge detection. IC Role / Device Role / Timing Role: Dual Schmitt trigger acts as a noise-immune signal conditioner and zero-crossing detector - each channel independently cleans one signal path. Use Value: Eliminates false triggering in industrial monitoring systems by rejecting sub-millisecond transients while preserving true signal transitions. |
Use Scenario: Generating precise, temperature-stable clock signals using only two external resistors and one capacitor in a feedback loop. IC Role / Device Role / Timing Role: One inverter forms the core gain stage; the second provides phase inversion to close the positive-feedback loop required for oscillation. Use Value: Achieves frequency stability within ±5% over -40 °C to +125 °C using the device's consistent hysteresis (VH = 0.4–0.71 V) and low tempco propagation delay. |
| Monostable Multivibrator | Sensor Interface Conditioning |
|
Use Scenario: Creating fixed-duration pulses from momentary switch closures or irregular sensor interrupts in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Configured with RC network to generate single-shot output pulses; Schmitt input ensures clean triggering despite contact bounce or EMI. Use Value: Reduces firmware overhead by offloading debouncing and pulse generation to hardware - extends battery life via deterministic timing. |
Use Scenario: Interfacing automotive crankshaft position sensors (variable reluctance type) with digital engine control units (ECUs). IC Role / Device Role / Timing Role: Converts low-amplitude, slow-slew analog sine-like sensor outputs into sharp-edged digital timing signals for ignition timing calculation. Use Value: Maintains accurate edge placement (<10 ns jitter) across wide temperature and supply variations - directly supporting ISO 16750-compliant ECU designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G14GW,125 | Same logic function and electrical specs, but in TSSOP6 (SOT363-2) package - 1.25 mm body width vs. 1.7 mm for SC-74. | Preferred for ultra-dense PCBs where footprint area is constrained; thermal resistance differs (83 °C derating start vs. 89 °C for SC-74). | Select when board space is prioritized over thermal margin or existing SC-74 footprint compatibility. |
| SN74HCT14DR | Hex (6-channel) version in SOIC-14; higher channel count, larger package, and different pinout - not pin-compatible. | Suitable for designs requiring >2 Schmitt triggers on same supply rail; adds routing complexity due to wider layout and extra unused channels. | Choose only when consolidating multiple functions onto one IC reduces total BOM cost and improves assembly yield. |
Compared with 74HCT2G14GW,125, the 74HCT2G14GV,125 offers better thermal derating margin (+6 °C before power dissipation reduction) and mechanical compatibility with legacy SC-74 footprints; versus SN74HCT14DR, it delivers minimal footprint and optimal channel utilization for dual-signal applications without wasted gates.

FAQ
What is the minimum recommended supply voltage for reliable TTL-level input recognition?
The 74HCT2G14GV,125 requires a minimum VCC of 4.5 V to guarantee correct interpretation of TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) per JEDEC JESD7A. At 4.5 V, VT+ is specified at 1.20–1.90 V and VT− at 0.50–1.20 V, ensuring ≥0.4 V hysteresis and noise margin compliance. Operation below 4.5 V risks undefined input behavior and reduced noise immunity.
Can this device drive a 50 pF capacitive load while maintaining specified propagation delay?
Yes - the 74HCT2G14GV,125's dynamic characteristics are explicitly tested at CL = 50 pF, with tpd = 21–48 ns across -40 °C to +125 °C and VCC = 4.5–5.5 V. Its output transition time (tt = 6–22 ns) and low CPD (10 pF) ensure stable timing performance into standard PCB trace and gate-input capacitance without external compensation.
How does the input clamp diode functionality enable overvoltage tolerance?
The integrated input clamp diodes allow safe connection of 1A or 2A to voltages up to VCC + 0.5 V (or down to -0.5 V) when series current-limiting resistors restrict IIK to ≤±20 mA. This permits direct interfacing with 12 V sensor outputs using a 1 kΩ resistor - clamping excess voltage to VCC or GND while preventing latch-up or permanent damage.
Is this part qualified for automotive applications per AEC-Q100?
No - the 74HCT2G14GV,125 is not AEC-Q100 qualified. While it operates from -40 °C to +125 °C and meets JESD78 latch-up and ESD standards, Nexperia's official documentation states it is intended for industrial and general-purpose use. Automotive-grade equivalents (e.g., 74HCT2G14-Q100) require separate qualification testing and part numbering.
