Product details

Overview

74LVC14AD-Q100 from Nexperia is an automotive-grade hex inverting Schmitt trigger IC with 5 V tolerant inputs, operating from 1.2 V to 3.6 V supply, qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), and packaged in SO14 (SOT108-1). It enables level translation between 3.3 V and 5 V logic domains in noisy automotive signal conditioning circuits.

For engineers reviewing the 74LVC14AD-Q100 datasheet, 74LVC14AD-Q100 pinout, 74LVC14AD-Q100 application, or 74LVC14AD-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.3–1.2 V), propagation delay (1.0–8.0 ns), 5.5 V absolute input voltage rating, and automotive temperature compliance - all critical for robust waveform shaping and noise immunity in vehicle ECUs.

Technical Context

This device implements six independent CMOS inverting Schmitt triggers, each with asymmetric positive- and negative-going input thresholds (e.g., VT+ = 1.2–2.0 V, VT− = 0.3–1.5 V at VCC = 3.6 V) to deliver 0.3–1.2 V hysteresis. Its input structure accepts voltages up to 5.5 V regardless of VCC, enabling direct interfacing with legacy 5 V TTL/CMOS without external level shifters.

The IC supports mixed-voltage system integration via 5 V tolerant inputs while maintaining low static current (≤40 μA at VCC = 3.6 V) and dynamic power dissipation governed by CPD = 15.6 pF. Propagation delay varies with supply voltage (e.g., 3.2 ns typ. at VCC = 3.0 V) and load (30–50 pF), with output skew ≤1.5 ns across buffers.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	1.2 V to 3.6 V - Enables operation in modern low-voltage automotive domains (e.g., 1.8 V or 3.3 V microcontroller I/O rails).
Input Voltage Range	0 V to 5.5 V - Allows direct connection to 5 V sensors or legacy logic without clamping diodes or resistors.
Propagation Delay	1.0–8.0 ns - Ensures fast edge detection in pulse shaping and oscillator timing applications up to ~100 MHz.
Hysteresis Voltage	0.3–1.2 V - Provides noise margin against EMI in under-hood environments (e.g., >200 mV typical at VCC = 3.3 V).
Operating Temperature	−40 °C to +125 °C - Meets AEC-Q100 Grade 1 requirements for engine control, body electronics, and ADAS modules.
ESD Protection	HBM >2000 V, CDM >1000 V - Sustains handling and board-level transients in automotive manufacturing and service environments.
Output Drive	±24 mA - Sufficient to drive multiple CMOS/TTL loads or small capacitive networks (e.g., RC oscillators).

Pinout & Package

Packaged in plastic small outline package (SO14, SOT108-1), 14-lead, 3.9 mm body width, with gull-wing leads and standard pin 1 index marking.

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A, 4A, 5A, 6A (Pins 1, 3, 5, 9, 11, 13)	Input	Schmitt-triggered inverter inputs - accept 0–5.5 V signals; enable noise-immune digital signal acquisition.
1Y, 2Y, 3Y, 4Y, 5Y, 6Y (Pins 2, 4, 6, 8, 10, 12)	Output	Inverted CMOS outputs - drive downstream logic or RC networks with rail-to-rail swing (0 V to VCC).
GND (Pin 7)	Ground Reference	0 V return path for all internal circuitry and output current - must be low-impedance for stable hysteresis.
VCC (Pin 14)	Supply Voltage	Primary power rail (1.2–3.6 V) - powers all six inverters; decoupling capacitor required near pin.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from −40 °C to +125 °C ambient - eliminates need for additional qualification testing in Tier 1 designs.
5 V tolerant inputs	Accepts up to 5.5 V on any input pin regardless of VCC - enables seamless interface with 5 V sensors, LIN transceivers, or legacy MCU peripherals.
Schmitt-trigger hysteresis	0.3–1.2 V window (VT+ − VT−) - rejects high-frequency noise on slow-rising signals (e.g., throttle position sensor outputs).
Unlimited input rise/fall times	No minimum slew rate requirement - accommodates slow analog-like signals (e.g., thermistor-based voltage dividers) without false triggering.
Low ICC static current	≤40 μA at VCC = 3.6 V - minimizes quiescent power in always-on vehicle modules (e.g., door module wake-up circuits).

Applications

Waveform Shaping

Astable Oscillator

Use Scenario: Converting noisy analog sensor outputs (e.g., crankshaft position Hall effect signals) into clean square waves for microcontroller capture.

IC Role / Device Role / Timing Role: Hex inverting Schmitt trigger - provides noise-immune signal conditioning and edge sharpening before timer input capture.

Use Value: Hysteresis ≥0.3 V suppresses EMI-induced glitches during engine cranking, ensuring accurate RPM calculation.

Use Scenario: Generating clock signals for LED flashers or watchdog timers using external R-C networks.

IC Role / Device Role / Timing Role: Inverter-based relaxation oscillator - one gate forms feedback loop with resistor and capacitor.

Use Value: Propagation delay variation <1.5 ns between gates ensures stable oscillation frequency with minimal jitter.

Monostable Pulse Generation

Level Translation Interface

Use Scenario: Creating fixed-duration pulses from momentary switch closures in vehicle lighting control.

IC Role / Device Role / Timing Role: Schmitt-trigger monostable multivibrator - uses RC time constant and hysteresis to define pulse width.

Use Value: Input threshold asymmetry (VT+ ≠ VT−) enables precise, repeatable pulse widths independent of input rise time.

Use Scenario: Interfacing 5 V CAN transceiver status pins to a 3.3 V microcontroller GPIO.

IC Role / Device Role / Timing Role: Bidirectional voltage translator - accepts 5 V logic high while powered from 3.3 V supply.

Use Value: 5.5 V absolute input rating eliminates external clamping diodes, reducing BOM count and PCB area.

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
SN74LVC14APWR	Industrial grade (−40 °C to +85 °C); no AEC-Q100 qualification; same SO14 package and pinout.	Not suitable for under-hood or safety-critical automotive locations requiring Grade 1 thermal range.	Select only for non-automotive or cabin-located modules where extended temperature is not required.
74LVC14ABQ-Q100	DHVQFN14 package (2.5 × 3 mm); side-wettable flanks for AOI; identical electrical specs and AEC-Q100 Grade 1 rating.	Better thermal performance and smaller footprint - preferred for space-constrained ADAS camera modules or radar units.	Choose when board space, thermal management, or automated optical inspection capability is prioritized over through-hole compatibility.

Compared with SN74LVC14APWR, the 74LVC14AD-Q100 adds automotive qualification and extended temperature support; compared with 74LVC14ABQ-Q100, it trades compactness and AOI capability for legacy SO14 assembly compatibility and thermal mass.

FAQ

Is the 74LVC14AD-Q100 pin-compatible with standard 74LVC14A variants?

Yes - the 74LVC14AD-Q100 shares identical pinout, function table, and DC/AC electrical characteristics with non-automotive 74LVC14A variants in SO14 packaging. The '-Q100' suffix denotes AEC-Q100 qualification and extended temperature grading, not pin or logic changes.

Can this device operate with a 1.8 V supply and interface to 5 V inputs simultaneously?

Yes - the device is fully specified for VCC = 1.8 V and supports VI up to 5.5 V on all inputs. Static and dynamic parameters (e.g., VOH ≥ 1.65 V, VOL ≤ 0.45 V at IO = ±4 mA) remain valid per datasheet Table 6 under these conditions.

What is the maximum recommended capacitive load for stable oscillation in an astable multivibrator?

For reliable RC oscillator operation, total load capacitance (including stray and gate input capacitance) should not exceed 50 pF. The device's CPD = 15.6 pF and tpd = 3.2 ns (typ.) at VCC = 3.0 V ensure predictable timing with standard 10–100 kΩ resistors and ≤33 pF ceramic capacitors.

Does the SO14 package (SOT108-1) support lead-free reflow soldering per JEDEC J-STD-020?

Yes - the 74LVC14AD-Q100 in SOT108-1 is qualified for lead-free reflow per JEDEC J-STD-020D, with peak temperature rating of 260 °C (10-second dwell). The package uses matte tin plating and meets IPC/JEDEC standards for wetting balance and intermetallic formation.
