Product details

Overview

74HCT2G14GV-Q100 from Nexperia is a dual inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and hysteresis of 0.4–0.71 V at VCC = 4.5–5.5 V. It transforms slow/noisy input edges into clean digital outputs in engine control units and body electronics.

For engineers reviewing the 74HCT2G14GV-Q100 datasheet, 74HCT2G14GV-Q100 pinout, 74HCT2G14GV-Q100 application, or 74HCT2G14GV-Q100 equivalent, key selection criteria include TTL-level input compatibility, guaranteed operation up to +125 °C, Schmitt-trigger hysteresis for noise immunity, and SC-74 (SOT457) 6-pin surface-mount package.

Technical Context

This device implements two independent inverting Schmitt triggers with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. Each channel provides sharp edge regeneration by leveraging distinct positive-going (VT+ = 1.20–2.10 V) and negative-going (VT− = 0.50–1.40 V) thresholds.

Its TTL-input logic family ensures compatibility with legacy 5 V microcontrollers and sensors, while the hysteresis (VH = 0.40–0.67 V) suppresses false triggering in high-noise automotive environments. Propagation delay is 21–48 ns at VCC = 4.5 V and CL = 50 pF across the full temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - Ensures robust operation with standard automotive 5 V rails and tolerates nominal 5 V ±10% variation.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood and powertrain applications per AEC-Q100 Grade 1.
Hysteresis Voltage (VH)	0.40–0.67 V at VCC = 4.5–5.5 V - Provides noise margin against EMI in engine control and sensor signal conditioning.
Propagation Delay	21–48 ns (VCC = 4.5 V, CL = 50 pF) - Enables reliable timing in relaxation oscillators and pulse shaping up to ~10 MHz.
Input Thresholds	VT+ = 1.20–2.10 V; VT− = 0.50–1.40 V - Defines precise switching windows for stable waveform regeneration in noisy analog interfaces.
Output Drive	±4.0 mA at VCC = 4.5 V - Sufficient to drive multiple CMOS/TTL loads or small capacitive nodes without external buffering.
ESD Protection	HBM > 2000 V, CDM > 1000 V - Meets automotive system-level ESD robustness requirements per JS-001/JS-002.

Pinout & Package

74HCT2G14GV-Q100 uses the SC-74 (SOT457) plastic surface-mounted package: 6-pin, 1.7 mm body width, 0.95 mm height, lead pitch 0.95 mm, and pin 1 index located at lower-left corner below marking "T14".

Pin/Terminal	Circuit Role	Design Meaning
1A	Channel 1 input	Inverting Schmitt trigger input with clamp diodes; accepts overvoltage signals when used with series resistor.
GND	Ground reference	0 V return path for both logic channels and internal bias networks; must be low-impedance for noise immunity.
2A	Channel 2 input	Independent inverting Schmitt trigger input; electrically isolated from 1A but shares GND and VCC.
2Y	Channel 2 output	Inverted, jitter-free digital output synchronized to 2A transitions; drives CMOS/TTL loads directly.
VCC	Positive supply	Primary power rail (4.5–5.5 V); powers both inverters and internal hysteresis circuitry.
1Y	Channel 1 output	Inverted, jitter-free digital output synchronized to 1A transitions; complements 2Y for dual-channel signal conditioning.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from −40 °C to +125 °C, including thermal cycling, humidity, and lifetime reliability testing.
TTL-compatible input levels	Accepts standard 0–0.8 V / 2.0–5.5 V logic thresholds-enables direct interface with legacy 5 V MCUs and sensors without level shifters.
Clamp diode protected inputs	Allows safe connection to signals exceeding VCC (e.g., 12 V sensor outputs) using external current-limiting resistors.
Unlimited input rise/fall times	Guarantees correct logic state transition even with extremely slow analog edges (e.g., thermistor or potentiometer wipers).
Low dynamic power dissipation	CPD = 10 pF enables sub-mW operation at typical automotive clock rates (<1 MHz), reducing thermal load in sealed modules.

Applications

Use Scenario: Conditioning analog signals from crankshaft position sensors exposed to high EMI and wide temperature swings.

IC Role / Device Role / Timing Role: Dual Schmitt trigger converts slow, noisy sine-to-square waveforms into clean, jitter-free digital pulses for microcontroller capture timers.

Use Value: Hysteresis of 0.4–0.67 V prevents false edge detection during engine cranking and eliminates need for external RC filtering.

Use Scenario: Debouncing mechanical door lock/unlock switches subject to contact bounce and voltage transients.

IC Role / Device Role / Timing Role: Inverting Schmitt trigger shapes switch closure events into monotonic logic transitions for microcontroller GPIO inputs.

Use Value: Guaranteed operation to +125 °C and HBM >2000 V ESD withstand enable reliable function in hot, vibration-prone cabin environments.

Automotive Lighting PWM Signal Shaping

Powertrain CAN Node Wake-Up Circuit

Use Scenario: Converting dimmer potentiometer wiper voltage into stable PWM enable signals for LED headlamp drivers.

IC Role / Device Role / Timing Role: Single channel acts as threshold comparator with hysteresis to generate clean on/off control from slow analog inputs.

Use Value: Unlimited input slew rate support allows direct connection to resistive dividers without additional op-amps or filters.

Use Scenario: Detecting low-frequency wake-up pulses on CAN bus lines to initiate microcontroller boot sequence.

IC Role / Device Role / Timing Role: One inverter conditions the differential CAN signal (via external resistor network) into a single-ended logic pulse.

Use Value: Input clamp diodes permit safe 5 V-tolerant interface to biased CAN lines; propagation delay <48 ns ensures timely wake-up response.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HC2G14GV-Q100	CMOS-input version; VT+ = 2.3–4.2 V, VT− = 1.13–2.6 V at VCC = 4.5–6.0 V; wider 2.0–6.0 V supply range.	Better suited for mixed-voltage systems (e.g., 3.3 V MCU with 5 V peripherals); less tolerant of TTL-level inputs.	Select when interfacing with 3.3 V logic or requiring broader supply flexibility; avoid if driving from standard 5 V TTL sources.
SN74LVC2G14QDCURQ1	TI's AEC-Q100 Grade 1 dual Schmitt trigger; 1.65–5.5 V supply; VH = 0.3–0.5 V; propagation delay 3.5–10.5 ns at 3.3 V.	Optimized for low-voltage 3.3 V systems; faster switching but lower hysteresis margin than Nexperia part.	Prefer for 3.3 V automotive domains (e.g., ADAS cameras); not drop-in compatible due to different pinout (X2SON-6 vs SOT457).

Compared with 74HC2G14GV-Q100 and SN74LVC2G14QDCURQ1, the 74HCT2G14GV-Q100 uniquely balances TTL compatibility, automotive-grade temperature range, and robust hysteresis-making it optimal for legacy 5 V automotive subsystems where noise immunity and input voltage tolerance are critical.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per AEC-Q100 qualification. Operation above 5.5 V voids automotive qualification and risks exceeding static current limits (ICC ≤ 20 μA at VCC = 5.5 V, Tamb = −40 °C to +125 °C).

Can this device interface directly with a 12 V sensor output?

Yes-input clamp diodes allow safe connection to 12 V signals when used with an external current-limiting resistor. For VI = 12 V and VCC = 5 V, a minimum 350 Ω resistor limits IIK to ≤20 mA, satisfying the absolute maximum rating and preventing latch-up.

How does hysteresis vary with temperature and supply voltage?

At VCC = 4.5 V, VH ranges from 0.40 V (min, −40 °C to +125 °C) to 0.71 V (typ, 25 °C); at VCC = 5.5 V, VH is 0.40–0.67 V. This controlled variation ensures consistent noise margin across full automotive temperature and supply ranges.

Is the SC-74 (SOT457) package RoHS and REACH compliant?

Yes-Nexperia confirms SOT457 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin termination and halogen-free molding compound, as documented in the official material declaration for 74HCT2G14GV-Q100.
