Product details

Overview

74AHC3G14DP-Q100 from Nexperia is a triple inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with 2.0–5.5 V supply range, overvoltage-tolerant inputs up to 5.5 V, and CMOS-level input compatibility-used for noise-immune signal conditioning in automotive body control modules.

For engineers reviewing the 74AHC3G14DP-Q100 datasheet, 74AHC3G14DP-Q100 pinout, 74AHC3G14DP-Q100 application, or 74AHC3G14DP-Q100 equivalent, key selection criteria include hysteresis voltage (0.45–1.6 V), propagation delay (1.0–16.5 ns), output drive capability (±25 mA), and TSSOP8 package compatibility with high-density automotive PCB layouts.

Technical Context

This device implements three independent Schmitt-trigger inverters in a single monolithic CMOS structure, each featuring asymmetric input thresholds (VT+ = 3.85 V, VT− = 1.65 V at VCC = 5.5 V) and 2.2 V hysteresis to reject slow-rising noise on sensor or switch inputs. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic domains and 5 V legacy signals without level-shifting circuitry.

The symmetric output impedance ensures matched rise/fall times (tr/tf ≤ 3.0 ns), while latch-up immunity (>100 mA per JESD78 Class II Level A) and robust ESD protection (HBM >2000 V, CDM >1000 V) support reliable operation in harsh automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.0–5.5 V - supports mixed-voltage board designs including 3.3 V microcontrollers and 5 V sensors
Hysteresis Voltage (VH)	0.45–1.6 V - enables stable switching in presence of ≥1.6 V peak-to-peak noise on input lines
Propagation Delay (tpd)	1.0–16.5 ns - guarantees sub-20 ns response for timing-critical debounce and oscillator circuits
Output Drive Current	±25 mA - directly drives LEDs, small relays, or fanout to ≥10 standard CMOS loads
Input Thresholds (VT+, VT−)	3.85 V / 1.65 V at VCC = 5.5 V - provides 2.2 V noise margin for noisy switch/sensor interfaces
Operating Temperature	-40 °C to +125 °C - meets under-hood automotive ambient requirements without derating
Power Dissipation Cap.	250 mW (TSSOP8) - allows full-speed operation at max temperature with minimal thermal design overhead

Pinout & Package

TSSOP8 plastic thin shrink small outline package (SOT505-2), 8-lead, 3 mm body width, 0.5 mm lead length, pin 1 index located below marking code 'A14' in lower-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 6	1A, 2A, 3A	Independent Schmitt-trigger input pins - accept overvoltage-tolerant signals up to 5.5 V
2, 5, 7	3Y, 1Y, 2Y	Inverted output pins - deliver rail-to-rail CMOS-compatible outputs with symmetrical drive strength
4	GND	Ground reference - must be low-impedance connection to minimize ground bounce in multi-inverter switching
8	VCC	Supply voltage input - requires local 100 nF ceramic decoupling within 5 mm of pin for stable high-speed operation

Key Features

Feature	Design Value

Overvoltage-tolerant inputs	Withstand 5.5 V regardless of VCC (2.0–5.5 V), eliminating need for external clamping diodes in mixed-voltage signal routing
High noise immunity	2.2 V hysteresis at 5.5 V supply rejects common-mode noise spikes exceeding ±1.1 V on sensor or switch inputs
CMOS low power dissipation	ICC ≤ 40 μA at VCC = 5.5 V - enables always-on wake-up detection in battery-sensitive automotive modules
Balanced propagation delays	tpd variation < 1.5 ns between channels - ensures deterministic timing in multi-phase relaxation oscillators and synchronized debouncing

Applications

Use Scenario: Low-cost clock generation for LED flashers or diagnostic timers where precision is non-critical.

IC Role / Device Role / Timing Role: One inverter forms feedback loop with RC network to generate stable square-wave output.

Use Value: Enables self-timed operation using only one IC and two passive components, with frequency tunable via R/C values.

Astable Multivibrator

Noise-Immune Sensor Interface

Use Scenario: Generating periodic wake-up pulses for low-power microcontrollers in telematics units.

IC Role / Device Role / Timing Role: Three inverters configured as ring oscillator to produce continuous clock signal.

Use Value: Delivers jitter-controlled oscillation with predictable startup and duty cycle stability across temperature.

Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, potentiometer) in HVAC control units exposed to motor noise.

IC Role / Device Role / Timing Role: Converts slow-rising analog threshold crossings into clean digital logic edges for ADC trigger or comparator replacement.

Use Value: Prevents false triggering caused by <100 ns noise transients, ensuring accurate state detection without additional filtering.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74AHCT3G14DP-Q100	TTL-compatible inputs (VIH = 2.0 V min), identical package and AEC-Q100 qualification	Required when interfacing with legacy 5 V TTL logic; slightly higher ICC at VCC = 5.5 V (≤40 μA vs. ≤10 μA)	Select for systems with mixed TTL/CMOS signaling where input threshold matching is critical
SN74LVC3G14-Q1 (TI)	Lower VCC range (1.65–5.5 V), LVC process yields faster tpd (0.9–7.5 ns), same TSSOP8 footprint	Preferred for ultra-low-voltage 1.8 V domains; lacks overvoltage tolerance beyond VCC	Choose when operating below 2.0 V or requiring sub-8 ns delay, but verify input voltage limits match system rails

Compared with 74AHCT3G14DP-Q100, the original part offers superior noise immunity at low VCC due to wider hysteresis, while SN74LVC3G14-Q1 enables earlier system wake-up in 1.8 V domains but requires strict adherence to VCC-referenced input limits.

FAQ

What is the maximum input voltage the 74AHC3G14DP-Q100 can tolerate?

The device supports overvoltage-tolerant inputs up to 5.5 V regardless of supply voltage (2.0–5.5 V), enabling safe interfacing with 5 V signals even when powered from 3.3 V. This eliminates external clamping components and simplifies mixed-voltage board design in automotive ECUs.

Can this IC be used to build an oscillator, and what components are needed?

Yes - a single 74AHC3G14DP-Q100 can form a relaxation oscillator using one inverter stage, one resistor, and one capacitor (Fig. 15). Typical values: R = 100 kΩ, C = 10 nF yield ~100 Hz output. Frequency scales inversely with R×C and depends on VT+ and VT− thresholds.

How does the hysteresis voltage change with supply voltage?

Hysteresis (VH) increases linearly with VCC: 0.45 V at 3.0 V, 1.4 V at 4.5 V, and 1.6 V at 5.5 V. This ensures consistent noise rejection margin across the full 2.0–5.5 V operating range, critical for stable operation in variable-battery automotive systems.

Is the TSSOP8 package RoHS-compliant and lead-free?

Yes - the SOT505-2 (TSSOP8) package is lead-free and RoHS-compliant per EU Directive 2011/65/EU, with matte tin (Sn) termination and halogen-free molding compound, meeting automotive environmental compliance requirements for solder reflow and long-term reliability.
