Product details
Overview
NLV74AC14DTR2G from onsemi is a hex Schmitt-trigger inverter IC designed for signal conditioning and noise-immune digital input interfacing. It features six independent inverters with 1.0 V typical hysteresis, 24 mA output drive capability, and operation across 2.0–6.0 V supply range-used in industrial control panels, automotive sensor signal cleanup, and microcontroller GPIO debouncing circuits.
For engineers reviewing the NLV74AC14DTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage stability over temperature, TTL-level compatibility (not applicable to AC variant), TSSOP-14 footprint constraints, and AEC-Q100 qualification status for automotive use cases.
Technical Context
The NLV74AC14DTR2G implements six independent CMOS Schmitt-trigger inverters using silicon-gate technology. Each channel provides sharp edge regeneration of slow-rising/falling signals, with input thresholds of Vt+ = 3.2 V and Vt− = 0.9 V at VCC = 4.5 V, yielding 1.4 V hysteresis under worst-case conditions.
It operates within −40°C to +85°C ambient temperature and supports 50 pF capacitive loads with propagation delays as low as 1.5 ns (typ) and ≤11.0 ns (max) at 5.0 V. The device draws ≤4.0 µA quiescent current and exhibits ±0.1 µA input leakage at 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex Schmitt-trigger inverter - enables reliable signal squaring of noisy or slow analog-like inputs |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Hysteresis Voltage | Typ. 1.0 V, min. 0.4 V at 4.5 V - ensures robust noise immunity against EMI and crosstalk in industrial environments |
| Output Drive | ±24 mA - sufficient to directly drive LEDs, small relays, or multiple CMOS inputs without buffering |
| Propagation Delay | ≤11.0 ns at 5.0 V, CL = 50 pF - meets timing requirements for sub-50 MHz clock/data conditioning |
| Input Capacitance | 4.5 pF - minimizes loading on upstream sensors or RC networks in front-end signal chains |
| Quiescent Current | ≤4.0 µA at 5.5 V - enables low-power operation in battery-backed or always-on monitoring systems |
Pinout & Package
TSSOP-14 (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (A1–A6) | CMOS-compatible Schmitt-trigger inputs - accept slow edges and reject noise below hysteresis window |
| 2, 4, 6, 8, 10, 12 | Output (Y1–Y6) | Inverted outputs with rail-to-rail swing - drive downstream logic or discrete loads up to 24 mA |
| 7 | GND | Ground reference for all inputs/outputs - must be low-impedance to maintain noise margin integrity |
| 14 | VCC | Positive supply - powers all six inverters; decoupling capacitor required within 1 cm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables clean digitization of analog waveforms (e.g., sine-to-square conversion) without external hysteresis components |
| 24 mA output sink/source | Eliminates need for external buffer transistors when driving optocouplers or small solenoids in PLC I/O modules |
| Wide 2.0–6.0 V supply range | Permits single-supply operation across legacy 5 V and modern 3.3 V embedded systems without redesign |
| Low 4.5 pF input capacitance | Preserves signal integrity in high-impedance sensor interfaces (e.g., thermistor or potentiometer wiper inputs) |
| AEC-Q100 qualified (NLV prefix) | Validated for automotive applications including engine control unit (ECU) signal conditioning and body electronics |
Applications
| Industrial Sensor Interface | Automotive Wheel Speed Sensing |
|---|---|
Use Scenario: Converting noisy analog pulses from inductive proximity sensors into clean square waves for PLC counter inputs. IC Role / Device Role / Timing Role: Signal conditioner and noise filter - transforms slow, ringing sensor outputs into jitter-free digital logic levels. Use Value: Prevents false counting due to EMI-induced glitches; eliminates need for external RC filtering and comparator circuits. | Use Scenario: Cleaning up sinusoidal back-EMF signals from passive wheel speed sensors before feeding to ABS controller ADC or timer capture pins. IC Role / Device Role / Timing Role: Analog-to-digital threshold translator - provides precise zero-crossing detection with built-in hysteresis. Use Value: Ensures accurate RPM measurement under harsh vibration and temperature cycling; meets AEC-Q100 Grade 2 requirements. |
| Microcontroller GPIO Debouncing | Power Supply Sequencing Monitor |
Use Scenario: Debouncing mechanical switch inputs connected to MCU GPIO pins in human-machine interface (HMI) panels. IC Role / Device Role / Timing Role: Hardware-level input synchronizer - removes contact bounce artifacts before software sampling. Use Value: Reduces firmware complexity and CPU load; guarantees deterministic response time independent of interrupt latency. | Use Scenario: Monitoring delayed power rail rise times (e.g., 3.3 V after 5 V) using RC time constants and feeding result to system supervisor logic. IC Role / Device Role / Timing Role: Threshold detector with hysteresis - triggers state change only after stable rail voltage exceeds defined window. Use Value: Prevents premature system startup during brown-out conditions; replaces discrete comparator + reference IC solutions. |
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 |
|---|---|---|---|
| MC74AC14DR2G | SOIC-14 package, same electrical specs, no AEC-Q100 qualification | Preferred for non-automotive industrial PCBs where board space allows larger SOIC footprint | Select when thermal performance (JA = 116°C/W) or hand-soldering ease outweighs space constraints |
| SN74LVC14APWR | 3.3 V only (1.65–3.6 V), lower 32 mA drive, different hysteresis profile (0.5 V typ) | Suitable for low-voltage portable electronics but not drop-in for 5 V or mixed-voltage systems | Choose only if system operates strictly at 3.3 V and requires smaller TSSOP-14 footprint than NLV74AC14DTR2G |
Compared with MC74AC14DR2G, NLV74AC14DTR2G offers automotive qualification and space savings in TSSOP-14, while SN74LVC14APWR trades voltage flexibility for lower power and tighter 3.3 V integration - none are pin-compatible replacements without layout review.

FAQ
What is the operating temperature range for NLV74AC14DTR2G?
The NLV74AC14DTR2G is rated for −40°C to +85°C ambient operating temperature. This range is validated per AEC-Q100 stress testing protocols and supports deployment in under-hood automotive locations and industrial control cabinets without derating. The device maintains specified hysteresis and propagation delay performance across this full range.
Does NLV74AC14DTR2G support 5 V TTL-level inputs?
No, NLV74AC14DTR2G does not support TTL-level inputs. It is the AC-series variant with CMOS-compatible input thresholds (Vt+ ≈ 3.2 V at 4.5 V VCC). For TTL compatibility, the MC74ACT14DTR2G variant must be used. The NLV74AC14DTR2G requires input high levels ≥70% VCC to guarantee switching.
What is the maximum capacitive load NLV74AC14DTR2G can drive reliably?
NLV74AC14DTR2G is characterized for reliable operation with up to 50 pF capacitive load per output, as confirmed in the AC Characteristics table. Driving loads beyond 50 pF increases propagation delay and may cause waveform rounding; for >50 pF, consider adding a series resistor or using a dedicated buffer like the NLV74AC04DTR2G.
Is NLV74AC14DTR2G pin-compatible with standard 74HC14 or 74LS14 devices?
Yes, NLV74AC14DTR2G uses the industry-standard 14-pin TSSOP layout matching 74HC14 and 74LS14 pinouts: inputs on odd pins (1,3,5,9,11,13), outputs on even pins (2,4,6,8,10,12), VCC on pin 14, and GND on pin 7. However, electrical behavior differs - AC-series has higher speed and drive strength than HC, and lacks LS's bipolar architecture.
How does the hysteresis of NLV74AC14DTR2G improve noise immunity?
The NLV74AC14DTR2G provides 1.0 V typical hysteresis between positive-going (Vt+) and negative-going (Vt−) input thresholds. This creates a noise margin window that prevents multiple output transitions when input signals hover near the switching point due to EMI or crosstalk - a critical advantage in motor drive feedback or sensor signal paths where noise spikes exceed 0.5 V peak-to-peak.
