Product details

Overview

74AHCT1G14GV-Q100 from Nexperia is a single-channel automotive-grade Schmitt-trigger inverter with TTL-compatible input thresholds, 5-pin SC-74A (SOT753) package, -40 °C to +125 °C operating range, 4.5 V–5.5 V supply, and 0.4 V/2.0 V input hysteresis at V_CC = 5.5 V. It functions as a noise-immune signal conditioner in automotive sensor interface and waveform shaping circuits.

For engineers reviewing the 74AHCT1G14GV-Q100 datasheet, 74AHCT1G14GV-Q100 pinout, 74AHCT1G14GV-Q100 application, or 74AHCT1G14GV-Q100 equivalent, key selection criteria include TTL-level input compatibility, AEC-Q100 Grade 1 qualification, Schmitt-trigger hysteresis for slow-edge signals, and SC-74A thermal performance in space-constrained ECUs.

Technical Context

This device implements a single inverting Schmitt trigger with asymmetric input thresholds: VT− = 0.6 V and VT+ = 2.0 V at V_CC = 5.5 V, yielding 1.4 V hysteresis. Its TTL-compatible inputs accept 0.8 V/2.0 V logic thresholds, enabling direct interfacing with legacy 5 V microcontrollers and sensors.

It operates strictly within 4.5 V–5.5 V supply range and delivers rail-to-rail CMOS outputs with symmetrical drive strength (±8 mA), while maintaining overvoltage-tolerant inputs up to 5.5 V-critical for mixed-voltage signal translation in automotive domains.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	4.5 V to 5.5 V - Ensures stable operation across automotive battery variations (e.g., cold-crank dips and load-dump transients).
Input Thresholds (V_CC = 5.5 V)	VT− = 0.6 V, VT+ = 2.0 V - Provides 1.4 V hysteresis to reject noise on slow-rising sensor signals like throttle position or coolant temperature.
Propagation Delay (CL = 15 pF)	4.1 ns (min) to 7.0 ns (max) - Enables reliable timing in relaxation oscillators and pulse edge sharpening up to ~100 MHz effective frequency.
Output Drive Strength	±8 mA at V_CC = 4.5 V - Sufficient to directly drive small capacitive loads (e.g., 15–50 pF PCB traces) without external buffering.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood and transmission-control module environments per AEC-Q100 Grade 1.
Input Overvoltage Tolerance	5.5 V - Allows safe connection to 5 V buses even when V_CC is powered down or unstable.
ESD Protection	HBM > 2000 V, CDM > 1000 V - Meets automotive assembly-line ESD robustness requirements without additional protection circuitry.

Pinout & Package

SC-74A (SOT753) plastic surface-mounted package: 5-terminal, leadless outline with 1.1 mm × 0.9 mm body, 0.65 mm pitch, and exposed pad not present. Thermal resistance R_θJA = 263 K/W (typical); power dissipation derates linearly at 3.8 mW/K above 85 °C.

Pin/Terminal	Circuit Role	Design Meaning
1	Not connected	No internal bond; must remain unconnected to avoid parasitic coupling or mechanical stress on die attach.
2	Data input (A)	TTL-compatible Schmitt-trigger input; accepts 0–5.5 V swing and provides noise immunity via hysteresis.
3	Ground (GND)	Reference node for all I/O and supply; requires low-inductance PCB connection to minimize ground bounce in switching.
4	Data output (Y)	Inverted, rail-to-rail CMOS output; drives capacitive loads up to 50 pF with <11 ns delay at 5 V.
5	Supply voltage (V_CC)	Primary power rail; bypass capacitor (100 nF ceramic) required within 3 mm for stable high-speed switching.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from −40 °C to +125 °C ambient, including lifetime reliability testing per stress test conditions.
Overvoltage-tolerant inputs	Withstands 5.5 V input regardless of V_CC state-enables safe level-shifting between 3.3 V and 5 V subsystems without external clamps.
Symmetrical output impedance	Ensures matched rise/fall times (<10% skew) for clean square-wave generation in oscillator and timing applications.
Low input leakage current	<2.0 μA max at −40 °C to +125 °C - preserves signal integrity in high-impedance sensor interfaces (e.g., thermistors, potentiometers).
High noise immunity	1.4 V hysteresis at 5.5 V supply rejects common-mode noise up to ±700 mV on slow-rising analog-derived digital signals.

Applications

Engine Coolant Temperature Sensing

Throttle Position Signal Conditioning

Use Scenario: Analog thermistor voltage divider output exhibits slow, noisy ramp transitions crossing logic threshold.

IC Role / Device Role / Timing Role: Schmitt-trigger inverter converts analog ramp into clean digital edge with defined hysteresis to prevent chatter during thermal drift.

Use Value: Eliminates false interrupts in ECU microcontroller by rejecting sub-700 mV noise spikes and ensuring monotonic edge detection.

Use Scenario: Potentiometer-based throttle signal contains mechanical bounce and EMI-induced glitches near threshold crossings.

IC Role / Device Role / Timing Role: Single inverter with TTL thresholds interfaces directly to 5 V MCU GPIO, providing debounced digital throttle status.

Use Value: Reduces firmware debounce overhead and eliminates need for RC filters or software polling, improving real-time response.

Relaxation Oscillator for Wake-Up Timer

Brake Light Switch Debounce

Use Scenario: Low-power wake-up circuit requires self-timed oscillator using minimal external components.

IC Role / Device Role / Timing Role: Inverter configured with RC feedback generates stable 1–10 kHz square wave; K-factor = 0.7–0.9 at 4.5–5.5 V.

Use Value: Enables ultra-low-quiescent-current sleep-mode timing without dedicated oscillator IC or crystal, saving BOM cost and board area.

Use Scenario: Mechanical brake light switch produces contact bounce lasting 5–20 ms during actuation.

IC Role / Device Role / Timing Role: Inverter with hysteresis acts as hardware debouncer feeding clean edge to CAN/LIN transceiver interrupt pin.

Use Value: Prevents spurious brake light activation or false collision alerts in ADAS systems, meeting ISO 26262 functional safety intent.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74AHC1G14GV-Q100	CMOS input thresholds (VT+ = 3.85 V, VT− = 1.65 V at 5.5 V); wider 2.0–5.5 V supply range.	Better suited for mixed-voltage systems with 3.3 V logic domains; less compatible with legacy 5 V TTL outputs.	Select when interfacing with 3.3 V MCUs or requiring lower supply voltage flexibility below 4.5 V.
SN74LVC1G14DBVR	Non-automotive; rated −40 °C to +125 °C but not AEC-Q100 qualified; 1.65–5.5 V supply; VT+ = 2.9 V at 5 V.	Lacks automotive qualification documentation and long-term reliability validation for safety-critical modules.	Acceptable for non-safety automotive infotainment or body electronics where AEC-Q100 is not mandated.

Compared with 74AHCT1G14GV-Q100, the AHC variant supports broader supply range and higher input thresholds but lacks native TTL compatibility, while the SN74LVC1G14DBVR offers identical pinout and function but no AEC-Q100 traceability-making the AHCT version optimal for legacy 5 V automotive control units requiring certified robustness.

FAQ

What is the maximum input voltage the 74AHCT1G14GV-Q100 can tolerate when V_CC is unpowered?

The device supports 5.5 V overvoltage-tolerant inputs independent of V_CC state. When V_CC = 0 V, inputs may be safely driven up to 5.5 V without damage or latch-up, enabling hot-plug and level-shift functionality in modular automotive subsystems.

Can this device drive a 50 pF capacitive load while maintaining specified propagation delay?

Yes. At V_CC = 5.0 V and CL = 50 pF, the typical propagation delay is 5.9 ns with a maximum of 11.0 ns across −40 °C to +125 °C, as confirmed in Table 9 of the datasheet-validating its use in PCB traces and small bus loads without added drivers.

How does the hysteresis voltage change with supply voltage?

Hysteresis (V_H) increases with V_CC: it is 1.4 V at 5.5 V, 1.4 V at 4.5 V, and 1.2 V at 3.0 V (for AHC variant). For 74AHCT1G14GV-Q100, VH remains 1.4 V from 4.5 V to 5.5 V, providing consistent noise margin across its operational supply window.

Is pin 1 on the SC-74A package marked with a dot or notch?

Per Section 5 (Marking) and Figure 18, pin 1 is located at the lower-left corner below the marking code "C14", identified by a molded index notch on the package body-not a dot. The notch aligns with the terminal row containing pins 1–3, confirming orientation during automated placement.
