Product details
Overview
NLV74HC14ADG from onsemi is a hex Schmitt-trigger inverter IC designed for noise-immune signal conditioning in automotive and industrial control systems. It operates from 2.0 V to 6.0 V, delivers ±25 mA output drive per channel, features input hysteresis (0.2–3.0 V typical), and supports −55 °C to +125 °C operation in SOIC-14 NB package.
For engineers reviewing the NLV74HC14ADG datasheet, pinout, applications, or equivalent options, this device is selected for robust digital input debouncing, slow-edge signal squaring, and EMI-tolerant interface conditioning in AEC-Q100-compliant designs.
Technical Context
The NLV74HC14ADG implements six independent CMOS Schmitt-trigger inverters with asymmetric input thresholds (VT+ min = 0.95 V, VT− max = 2.65 V at VCC = 6.0 V), enabling reliable switching in high-noise environments. Each inverter exhibits hysteresis voltage (VH) ranging from 0.20 V to 3.00 V depending on supply voltage and temperature.
It is fully compatible with standard CMOS outputs and-when used with pullup resistors-with LSTTL outputs. Its propagation delay is 13 ns (max) at VCC = 6.0 V, and transition time is 13 ns (max), supporting clean edge generation up to ~30 MHz under light capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interfacing with 3.3 V and 5 V logic domains without level shifters |
| Hysteresis Voltage (VH) | 0.20 V to 3.00 V - provides noise margin against EMI-induced false triggering in automotive harnesses |
| Propagation Delay (tPLH/tPHL) | 13 ns max at VCC = 6.0 V - supports reliable timing in clock conditioning and debounce circuits up to 30 MHz |
| Output Drive | ±25 mA per pin - sufficient to directly drive LEDs, small relays, or fanout to 10 LSTTL loads |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
| Input Leakage Current | ±1.0 µA max at VCC = 6.0 V - ensures low power consumption in battery-backed sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74HC14ADG | Same core logic and pinout; rated for −40 °C to +85 °C commercial temperature range, not AEC-Q100 qualified | Not suitable for automotive under-hood or chassis-mounted use; limited to industrial or consumer ambient conditions | Select when cost sensitivity outweighs extended temperature or automotive qualification requirements |
| SN74HC14DR | TI part with identical function and pinout; specified for −40 °C to +85 °C; different AC timing (tPLH max = 21 ns at 6 V) | Lacks AEC-Q100 qualification and automotive PPAP support; may require requalification in safety-critical systems | Choose for TI-design ecosystems or where dual-sourcing across vendors is prioritized over automotive compliance |

FAQ
What is the maximum operating temperature for NLV74HC14ADG?
The NLV74HC14ADG is rated for operation from −55 °C to +125 °C, meeting AEC-Q100 Grade 1 requirements. This specification is validated across the full SOIC-14 NB package and applies to all six inverters simultaneously under recommended supply and load conditions. The NLV74HC14ADG maintains guaranteed hysteresis and propagation delay performance throughout this range.
Does NLV74HC14ADG support 3.3 V logic systems?
Yes, NLV74HC14ADG operates reliably at VCC = 3.3 V. At this voltage, its typical hysteresis is ~0.8 V, input thresholds are VT+ ≈ 2.1 V and VT− ≈ 1.3 V, and output VOH/VOL remain compatible with 3.3 V CMOS inputs. The NLV74HC14ADG requires no level-shifting circuitry when interfacing with 3.3 V microcontrollers or FPGAs.
Is NLV74HC14ADG pin-compatible with standard 74HC14 devices?
Yes, NLV74HC14ADG uses the same SOIC-14 NB footprint and identical pin assignment as MC74HC14ADG and SN74HC14DR. Pin 1 is A1, pin 2 is Y1, ..., pin 7 is GND, pin 14 is VCC. No PCB layout changes are required when upgrading from commercial-grade HC14 variants to the NLV74HC14ADG in existing designs.
What is the input hysteresis voltage of NLV74HC14ADG at 5 V supply?
At VCC = 5.0 V, the NLV74HC14ADG exhibits a minimum hysteresis voltage (VHmin) of 0.40 V and a maximum (VHmax) of 2.25 V across temperature. Typical hysteresis is approximately 1.3 V, calculated as the difference between typical VT+ (≈3.2 V) and VT− (≈1.9 V). This value ensures robust noise rejection in 5 V automotive and industrial signal paths.
Can NLV74HC14ADG drive an LED directly?
Yes, NLV74HC14ADG can drive a standard 2 mA LED directly when configured in active-low mode (anode to VCC, cathode to Yx output). With VOL ≤ 0.26 V at IOUT = 2.4 mA and VCC = 3.0 V, it provides sufficient sink current and low saturation voltage. For higher-current LEDs, an external transistor stage is recommended to avoid exceeding the NLV74HC14ADG's ±25 mA absolute maximum rating.
