Product details
Overview
NLV74HC14ADR2G from onsemi is a hex Schmitt-trigger inverter IC designed for noise-immune signal conditioning in digital systems. It features six independent inverters with hysteresis, operates from 2.0 V to 6.0 V, delivers ±25 mA output drive per channel, and supports industrial temperature range (–55 °C to +125 °C). It is commonly used to square up slow-rising clock or sensor signals in automotive body control modules.
For engineers reviewing the NLV74HC14ADR2G datasheet, pinout, applications, or equivalent options, key selection criteria include input hysteresis voltage (0.2–3.0 V), propagation delay (13–110 ns), CMOS-level thresholds, SOIC-14 package compatibility, and AEC-Q100 qualification for automotive use.
Technical Context
The NLV74HC14ADR2G implements six independent Schmitt-trigger inverters using high-performance silicon-gate CMOS technology. Each inverter exhibits asymmetric input thresholds (VT+ and VT−) to provide hysteresis, enabling reliable switching in electrically noisy environments such as engine bays or industrial motor controls.
It complies with JEDEC Std 7.0A, supports TTL- and CMOS-level interfacing, and integrates 72 FETs (18 equivalent gates) per package. The device uses standard CMOS input thresholds - not TTL - distinguishing it from the HCT variant, and is specified for operation across the full –55 °C to +125 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Hysteresis Voltage (VH) | 0.20 V min to 3.00 V max - Ensures robust noise rejection (>400 mV typical at 5 V) for signals with slow edges or EMI coupling. |
| Propagation Delay (tPLH/tPHL) | 13 ns max at VCC = 6.0 V - Supports clean signal regeneration up to ~30 MHz input edge rates. |
| Output Drive | ±25 mA per pin - Sufficient to directly drive multiple LSTTL loads or small capacitive bus lines. |
| Input Leakage Current | ±1.0 µA max at 6.0 V - Minimizes power loss in battery-backed or low-quiescent systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74HC14ADR2G | Same die, non-automotive grade; lacks AEC-Q100 qualification and extended temp validation. | Approved for commercial/industrial use only; not certified for automotive production. | Select when AEC-Q100 is not required and cost sensitivity outweighs qualification needs. |
| SN74LVC14APWR | 3.3 V only (1.65–3.6 V), lower hysteresis (≈0.3 V typ), faster propagation (5.5 ns typ at 3.3 V). | Better suited for high-speed 3.3 V FPGA/CPLD interfaces; unsuitable for 5 V or wide-VCC systems. | Choose for modern low-voltage digital systems where speed matters more than voltage flexibility. |
Compared with MC74HC14ADR2G, NLV74HC14ADR2G adds AEC-Q100 qualification and extended –55 °C operation, while SN74LVC14APWR trades voltage range for speed and lower power - making NLV74HC14ADR2G the only option qualified for under-hood automotive deployment with 2.0–6.0 V support.

FAQ
What is the maximum operating temperature for NLV74HC14ADR2G?
The NLV74HC14ADR2G is rated for junction temperatures from –55 °C to +150 °C and operates reliably across an ambient range of –55 °C to +125 °C. This specification is validated per AEC-Q100 Grade 1 requirements, making NLV74HC14ADR2G suitable for under-hood automotive applications where thermal stress is critical.
Does NLV74HC14ADR2G support 3.3 V logic systems?
Yes, NLV74HC14ADR2G fully supports 3.3 V operation: its recommended supply range (2.0 V to 6.0 V) includes 3.3 V, and all DC and AC parameters - including hysteresis voltage (~0.9 V min at 3.3 V) and propagation delay (~19 ns max) - are guaranteed at that voltage. NLV74HC14ADR2G interfaces directly with 3.3 V microcontrollers without level translation.
How does NLV74HC14ADR2G differ from MC74HC14ADR2G?
NLV74HC14ADR2G is the automotive-grade variant of MC74HC14ADR2G, featuring identical electrical characteristics but with AEC-Q100 qualification, extended –55 °C to +125 °C ambient operation, and PPAP documentation support. The "NLV" prefix denotes onsemi's automotive logic series, whereas MC74HC14ADR2G is commercial/industrial grade only.
Can NLV74HC14ADR2G replace a standard 74HC14 in existing designs?
Yes - NLV74HC14ADR2G is pin-compatible and functionally identical to standard 74HC14 variants in SOIC-14 packaging. Its wider temperature range, AEC-Q100 qualification, and tighter parametric limits make it a drop-in upgrade for reliability-critical designs, provided the PCB layout accommodates the same SOIC-14 footprint and thermal relief.
What is the input hysteresis voltage of NLV74HC14ADR2G at 5 V supply?
At VCC = 5.0 V, NLV74HC14ADR2G guarantees a minimum hysteresis voltage (VHmin) of 0.40 V and a maximum (VHmax) of 2.25 V, with typical value around 1.0 V. This hysteresis ensures stable switching in presence of up to ±200 mV noise, making NLV74HC14ADR2G ideal for conditioning signals from noisy sources like relays or unshielded sensors.
