Product details

Overview

NLV74AC14DR2G from onsemi is a hex Schmitt-trigger inverter IC designed for signal conditioning and noise-immune digital interface applications. It features six independent inverters with hysteresis (typ. 1.0 V at V_CC = 5.0 V), CMOS-compatible inputs/outputs, ±24 mA output drive capability, and operates across 2.0–6.0 V supply range. It is widely used in clock shaping, debouncing mechanical switches, and waveform regeneration in industrial control systems.

For engineers reviewing the NLV74AC14DR2G datasheet, pinout, applications, or equivalent options, key selection criteria include input hysteresis width, propagation delay (t_PLH/t_PHL ≤ 11.0 ns at 5.0 V), output drive strength, SOIC-14 package compatibility, and AEC-Q100 qualification status for automotive-grade variants.

Technical Context

The NLV74AC14DR2G implements six independent Schmitt-trigger inverters using high-performance silicon-gate CMOS technology. Each inverter exhibits asymmetric input thresholds (V_t+ ≈ 3.2 V, V_t− ≈ 0.9 V at V_CC = 4.5 V), delivering 1.4 V typical hysteresis that remains stable over temperature and supply voltage variations.

It supports rail-to-rail input and output operation, delivers ±24 mA DC output current per channel, and achieves propagation delays as low as 6.0 ns (t_PHL, typ.) under 5.0 V/50 pF conditions. The device is specified for −40°C to +85°C ambient operation and meets JEDEC JESD78 latch-up immunity (>100 mA).

Key Specifications

Applications

Switch Debouncing	Waveform Shaping
Use Scenario: Mechanical pushbutton or rotary encoder signals exhibit contact bounce lasting 1–10 ms. IC Role / Device Role / Timing Role: NLV74AC14DR2G acts as a hardware-level signal conditioner, converting noisy transitions into clean, monotonic logic edges. Use Value: Eliminates firmware-based debounce delays and CPU polling overhead while ensuring deterministic response <12 ns after stable input crossing threshold.	Use Scenario: Sine or triangle wave oscillator output requires conversion to square wave for clock distribution. IC Role / Device Role / Timing Role: NLV74AC14DR2G functions as a zero-crossing detector with built-in hysteresis, rejecting amplitude noise during transition. Use Value: Delivers jitter-free output with <11 ns propagation delay variation, enabling stable timing in PLL reference paths and ADC sampling clocks.
Industrial Sensor Interface	Legacy Bus Level Translation
Use Scenario: Resistive temperature sensor (RTD) or potentiometer output feeds comparator with slow slew rate (<1 V/ms). IC Role / Device Role / Timing Role: NLV74AC14DR2G serves as a threshold-detecting front-end stage, providing clean digital enable/disable signals to PLC I/O modules. Use Value: Hysteresis prevents chattering at trip point; ±24 mA drive directly interfaces with 24 V DC input cards without external transistor buffering.	Use Scenario: 3.3 V FPGA needs to communicate with 5 V TTL-level peripheral via shared bus. IC Role / Device Role / Timing Role: NLV74AC14DR2G operates as a unidirectional level shifter - its CMOS input accepts 3.3 V logic, while output swings rail-to-rail to 5 V. Use Value: No external biasing or pull-ups required; 6-channel integration reduces board space vs discrete MOSFET solutions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC74AC14DG	Same die, SOIC-14 rail packaging (55 units/rail) vs. NLV74AC14DR2G's tape-and-reel (2500/reel); identical electrical specs and thermal performance	Preferred for prototyping and low-volume evaluation where manual handling is acceptable	Select MC74AC14DG for bench validation; NLV74AC14DR2G for automated SMT production
SN74LV14APWR	Lower V_CC range (2.0–5.5 V), reduced hysteresis (min 0.3 V), lower drive (±6 mA), TSSOP-14 package	Better suited for ultra-low-power portable devices but lacks noise immunity and drive for industrial actuator control	Choose SN74LV14APWR only when power budget <10 μA/MHz is critical and noise environment is benign

Compared with MC74AC14DG, NLV74AC14DR2G offers optimized logistics for volume manufacturing; versus SN74LV14APWR, it delivers 4× higher output current and >4× wider hysteresis - essential for reliability in harsh EMI-prone settings like motor drives and factory automation.

FAQ

What is the maximum operating supply voltage for NLV74AC14DR2G?

The NLV74AC14DR2G supports a DC supply voltage range of 2.0 V to 6.0 V. Its absolute maximum rating is +6.5 V, but sustained operation above 6.0 V risks parametric shift and reduced reliability. All guaranteed specifications - including propagation delay, output drive, and hysteresis - are validated only within the 2.0–6.0 V recommended operating range per the official onsemi datasheet Rev. 11.

Does NLV74AC14DR2G have AEC-Q100 qualification?

The NLV74AC14DR2G itself is not explicitly AEC-Q100 qualified; however, the automotive-grade variant NLV74AC14DR2G−Q (with −Q suffix) is AEC-Q100 qualified and PPAP capable. The base NLV74AC14DR2G shares the same die and process, but qualification documentation and test reports apply only to the −Q version. For automotive applications, designers must specify NLV74AC14DR2G−Q to meet OEM compliance requirements.

What is the typical hysteresis voltage of NLV74AC14DR2G at 5.0 V supply?

At V_CC = 5.0 V, the NLV74AC14DR2G exhibits a typical hysteresis voltage (V_H = V_t+ − V_t−) of 1.6 V, with guaranteed minimum of 0.5 V and maximum of 1.6 V over −40°C to +85°C. This wide, stable hysteresis enables reliable operation in noisy environments such as motor control feedback loops or industrial switch inputs where EMI could otherwise cause false triggering.

Can NLV74AC14DR2G drive a 10 kΩ pull-up resistor directly?

Yes - NLV74AC14DR2G can directly drive a 10 kΩ pull-up to V_CC. With V_CC = 5.0 V, the worst-case high-level output voltage (V_OH) is 4.4 V at I_OH = −24 mA. Driving 10 kΩ draws only 0.5 mA, well within spec, resulting in V_OH > 4.95 V (typ.). This makes NLV74AC14DR2G ideal for open-drain interface emulation or wired-OR bus termination without external transistors.

Is NLV74AC14DR2G pin-compatible with MC74AC14DR2G?

Yes - NLV74AC14DR2G is functionally and physically pin-compatible with MC74AC14DR2G. Both use identical SOIC-14 (Case 751A) packaging, share the same pinout (14-pin dual in-line with GND at Pin 7, V_CC at Pin 14), and implement identical Schmitt-trigger inverter logic. The "NLV" prefix denotes onsemi's enhanced industrial temperature grade (−40°C to +105°C), whereas MC74AC14DR2G is rated for −40°C to +85°C; both are drop-in replacements in most designs unless extended temperature operation is required.
