Product details

Overview

74LV14BQ,115 from Nexperia is a low-voltage CMOS hex inverting Schmitt trigger IC with 14-terminal DHVQFN package, operating from 1.0 V to 5.5 V supply, delivering six independent hysteresis-input buffers for noise-immune signal conditioning. It transforms slow-rising/falling inputs into clean digital outputs and supports industrial temperature range (−40 °C to +125 °C), widely used in relaxation oscillators and waveform shaping in motor control feedback loops.

For engineers reviewing the 74LV14BQ,115 datasheet, 74LV14BQ,115 pinout, 74LV14BQ,115 application, or 74LV14BQ,115 equivalent, key selection criteria include input hysteresis voltage (VH = 0.3 V to 1.5 V), propagation delay (13 ns typical at 3.3 V/15 pF), output drive capability (±6 mA), and thermal-enhanced DHVQFN14 packaging for high-density PCB layouts.

Technical Context

The 74LV14BQ implements six identical inverting Schmitt-trigger stages, each with asymmetric switching thresholds (VT+ and VT−) defined per supply voltage-e.g., VT+ = 1.60 V and VT− = 1.05 V at VCC = 3.0 V-yielding 0.55 V hysteresis. Its CMOS architecture ensures rail-to-rail output swing and ultra-low static current (≤40 μA at 5.5 V).

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), and features ESD robustness (HBM >2000 V, CDM >1000 V), latch-up immunity (>100 mA), and TTL-level compatibility at VCC = 2.7–3.6 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.0 V to 5.5 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains
Input Hysteresis (VH)	0.3 V to 1.5 V - rejects noise up to ±750 mV on slow edges without false triggering
Propagation Delay (tpd)	13 ns typical at VCC = 3.3 V, CL = 15 pF - supports >30 MHz clock shaping in oscillator circuits
Output Drive	±6 mA at VCC = 3.0 V - sufficient to directly drive LED indicators or small capacitive loads (≤50 pF)
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive subsystems and industrial PLC I/O modules
Power Dissipation	500 mW max at Tamb ≤ 98 °C - derates 9.6 mW/K above 98 °C due to DHVQFN thermal design
Input Leakage Current	≤1.0 μA at VCC = 5.5 V - preserves battery life in always-on sensor wake-up circuits

Pinout & Package

DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, exposed thermal pad (non-soldered by default), 14 terminals in quad arrangement with terminal 1 index area marked.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	Schmitt-trigger inputs accepting slow analog-like signals; each has independent VT+/VT− thresholds
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Inverted, rail-to-rail CMOS outputs; capable of driving capacitive loads up to 50 pF with <13 ns delay
7	GND	Reference ground for all inputs, outputs, and internal circuitry; must be low-impedance for stable hysteresis
14	VCC	Main supply pin; decoupling capacitor (100 nF) required within 3 mm for noise immunity and ground bounce suppression
Terminal 1 Pad	Thermal pad	Non-electrical thermal enhancement; floating or connected to VCC only-no GND connection permitted

Key Features

Feature	Design Value
Wide VCC range (1.0–5.5 V)	Enables single-bom deployment across legacy 5 V and modern ultra-low-power 1.2 V systems
TTL-compatible inputs (2.7–3.6 V)	Allows direct interface with legacy microcontroller GPIOs without level-shifting
Low ground bounce (<0.8 V)	Maintains signal integrity during simultaneous output switching in dense routing environments
JEDEC-compliant hysteresis	Guarantees consistent noise margin across voltage grades-critical for reliable reset or enable signal generation
−40 °C to +125 °C operation	Validated for use in engine control units, industrial inverters, and outdoor IoT gateways

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LV14APWR	TSSOP14 package (SOT402-1); 4.4 mm body width; 0.65 mm pitch; no thermal pad	Lower thermal performance; unsuitable for sustained 125 °C ambient or high-duty-cycle oscillators	Select when board space allows larger footprint and thermal load is moderate
74HC14PW,118	Higher VCC min = 2.0 V; no 1.0–1.8 V operation; VT+ ≈ 3.0 V at 5 V - wider hysteresis but incompatible with sub-2 V systems	Cannot replace in 1.2 V or 1.8 V domains; requires level translation for mixed-voltage designs	Choose only for legacy 5 V-only systems where LV voltage flexibility is unnecessary

Compared with SN74LV14APWR and 74HC14PW,118, the 74LV14BQ,115 uniquely combines ultra-low-voltage operation (down to 1.0 V), DHVQFN thermal efficiency, and full industrial temperature qualification-making it the sole option for compact, wide-input-voltage, high-reliability Schmitt buffering.

FAQ

Can 74LV14BQ,115 operate reliably at 1.2 V supply?

Yes. The device is fully specified down to 1.0 V supply, with guaranteed functionality including Schmitt-trigger thresholds (VT+ = 0.70 V, VT− = 0.34 V) and propagation delay (80 ns typical) at VCC = 1.2 V and −40 °C to +85 °C. Static current remains below 1.0 μA, making it ideal for battery-backed sensor nodes.

Is the thermal pad on the DHVQFN package electrically connected?

No. The terminal 1 pad is a non-electrical thermal enhancement feature. Per datasheet Section 6.1, it must remain floating or be connected solely to VCC-never to GND-to avoid internal current leakage paths and ensure latch-up immunity.

What is the maximum capacitive load the outputs can drive while maintaining 13 ns propagation delay?

The 13 ns typical tpd is specified at CL = 15 pF. At CL = 50 pF, propagation delay increases to ≤28 ns (−40 °C to +125 °C). Output rise/fall times remain <2.5 ns (VCC ≥ 2.7 V), supporting reliable driving of microcontroller inputs, small LEDs, or short PCB traces without external buffers.

Does 74LV14BQ,115 support mixed-voltage interfacing between 3.3 V and 5 V domains?

Yes. With VCC = 3.3 V, inputs accept TTL levels (0.8 V/2.0 V thresholds), allowing direct connection to 5 V outputs. Outputs swing rail-to-rail (0 V/3.3 V), so a series resistor + clamping diode or dedicated level shifter is required to safely interface with 5 V inputs.
