Product details
Overview
MC74HC14ADTR2G-Q from onsemi is a hex Schmitt-trigger inverter IC designed for signal conditioning in noisy or slow-transition environments. It features six independent CMOS-level hysteresis inverters, operates from 2.0 V to 6.0 V, delivers ±25 mA output drive per channel, and supports automotive-grade AEC-Q100 qualification. It is commonly used to square up degraded clock or sensor signals in engine control units and industrial I/O modules.
For engineers reviewing the MC74HC14ADTR2G-Q datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.20–3.00 V), propagation delay (13–110 ns), input threshold asymmetry, TSSOP-14 package thermal resistance (150 °C/W), and AEC-Q100 PPAP capability.
Technical Context
The MC74HC14ADTR2G-Q implements six independent Schmitt-trigger inverter stages using high-performance silicon-gate CMOS technology. Each stage provides asymmetric input thresholds (VT+ and VT−) with hysteresis ranging from 0.20 V to 3.00 V depending on supply voltage, enabling robust noise rejection in environments with >200 mV of coupled interference.
It uses standard CMOS input thresholds (not TTL-compatible), supports rail-to-rail output swing, and maintains stable operation across –55 °C to +125 °C. The device draws ≤40 µA quiescent current at 6.0 V and exhibits ≤10 pF input capacitance - critical for high-frequency signal integrity in sensor interface and clock clean-up circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5.0 V logic systems without level shifting |
| Hysteresis Voltage (VH) | 0.20 V min to 3.00 V max - defines minimum input noise margin before false triggering |
| Propagation Delay (tPLH/tPHL) | 13 ns @ 6.0 V - determines maximum clean-up frequency for slow analog or mechanical switch inputs |
| Output Drive Current | ±25 mA per pin - sufficient to directly drive LSTTL loads or small LEDs without external buffers |
| Input Capacitance (Cin) | 10 pF max - minimizes loading on high-impedance sources like crystal oscillators or capacitive sensors |
| Operating Temperature | –55 °C to +125 °C - certified for under-hood automotive and industrial control applications |
| ESD Withstand (HBM) | 4000 V - ensures reliability during board handling and system integration |
Pinout & Package
TSSOP-14 (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (A1–A6) | CMOS-level Schmitt-trigger inputs; each requires explicit tie-high or tie-low if unused |
| 2, 4, 6, 8, 10, 12 | Output (Y1–Y6) | Inverted, rail-to-rail CMOS outputs; capable of sourcing/sinking 25 mA |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-inductance connection |
| 14 | VCC | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Six independent Schmitt-trigger inverters | Enables parallel signal conditioning of multiple slow-rising sensor or switch inputs without cross-talk |
| CMOS-level input thresholds | Ensures compatibility with 3.3 V microcontrollers and avoids false triggering from TTL-level noise |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV14APWR | Lower VCC range (1.65–5.5 V); 1.5 ns faster tPLH at 3.3 V; non-automotive grade | Lacks AEC-Q100 qualification; unsuitable for under-hood deployment | Select when cost-sensitive consumer or industrial designs require higher speed at 3.3 V and do not need automotive certification |
| 74HC14D,118 | SOIC-14 package only; identical electrical specs but no −Q suffix or PPAP support | No automotive qualification documentation or controlled change management | Choose for non-automotive applications where TSSOP footprint is unnecessary and SOIC layout is preferred |
Compared with SN74LV14APWR and 74HC14D,118, the MC74HC14ADTR2G-Q uniquely combines AEC-Q100 Grade 1 qualification, TSSOP-14 thermal performance (150 °C/W), and guaranteed hysteresis down to 2.0 V - making it the only option qualified for safety-critical automotive signal conditioning where both package density and process traceability are mandatory.

FAQ
What is the maximum operating temperature for the MC74HC14ADTR2G-Q?
The MC74HC14ADTR2G-Q is rated for continuous operation from –55 °C to +125 °C ambient temperature. This full Grade 1 AEC-Q100 temperature range is validated per JEDEC JESD22-A108 and confirmed in the official onsemi datasheet Rev. 16 (March 2024). The device maintains specified hysteresis and propagation delay performance across this entire range, making it suitable for under-hood automotive use.
Does the MC74HC14ADTR2G-Q support 3.3 V logic systems?
Yes, the MC74HC14ADTR2G-Q fully supports 3.3 V operation. Its recommended supply range is 2.0 V to 6.0 V, and all DC and AC specifications - including VT+, VT−, VOH, VOL, and tPLH - are guaranteed at 3.3 V. At that voltage, typical hysteresis is ~0.8 V and propagation delay is ~22 ns, enabling reliable interface with 3.3 V microcontrollers and FPGAs.
Is the MC74HC14ADTR2G-Q pin-compatible with the MC74HCT14ADTR2G-Q?
No, the MC74HC14ADTR2G-Q is not pin-compatible with the MC74HCT14ADTR2G-Q in terms of input threshold behavior, though both share identical TSSOP-14 pinout and function table. The MC74HC14ADTR2G-Q uses CMOS-level thresholds (VT+ ≈ 3.15 V @ 4.5 V), while the HCT version uses TTL-level thresholds (VT+ ≈ 2.0 V @ 4.5 V). Swapping them requires verification of source driver compatibility.
What is the purpose of the "−Q" suffix in MC74HC14ADTR2G-Q?
The "−Q" suffix in MC74HC14ADTR2G-Q indicates automotive qualification: AEC-Q100 Grade 1 compliance, PPAP capability, and dedicated manufacturing site/control change requirements. It guarantees traceability, lot-level test data, and controlled process changes - essential for Tier 1 automotive suppliers. The base part MC74HC14ADTR2G lacks these certifications and associated documentation.
Can unused inputs on the MC74HC14ADTR2G-Q be left floating?
No, unused inputs on the MC74HC14ADTR2G-Q must never be left floating. Per the onsemi datasheet (page 3, Note 4), all unused inputs must be tied to a valid logic level - either VCC or GND - to prevent increased ICC, erratic output behavior, or excessive power consumption due to input stage oscillation. This requirement applies regardless of whether the device is operated at 2.0 V or 6.0 V.
