Product details
Overview
MC74VHC1G14DTT1G from onsemi is a single Schmitt-trigger inverter in TSOP-5 package, designed for 2.0 V to 5.5 V operation with CMOS-level input thresholds, 4.0 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and over-voltage tolerant inputs/outputs up to 5.5 V - used for noise-immune signal conditioning in automotive sensor interfaces and level-shifting between 3 V and 5 V logic domains.
For engineers reviewing the MC74VHC1G14DTT1G datasheet, pinout, applications, or equivalent options, this page delivers verified pin assignments, real-world interface use cases, exact threshold voltages (VT+ = 2.15 V / VT− = 1.65 V at VCC = 5.5 V), hysteresis of 0.50 V (typ), and AEC-Q100-qualified alternatives for automotive-grade designs.
Technical Context
The MC74VHC1G14DTT1G implements a three-stage buffered inverter architecture with Schmitt-trigger input hysteresis to reject noise on slow-rising or noisy signals. Its input structure tolerates up to 5.5 V regardless of VCC, enabling safe 5 V-to-3 V interfacing without external clamping.
IOFF functionality provides partial power-down protection when VCC = 0 V, and output structures tolerate overvoltage conditions during hot insertion or battery backup scenarios. The device operates across −55 °C to +125 °C and meets AEC-Q100 Grade 1 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports mixed-supply systems including automotive 3.3 V and industrial 5 V rails |
| tPD (typ) | 4.0 ns at VCC = 5.5 V, CL = 15 pF - enables high-speed signal edge sharpening in timing-critical paths |
| VT+ / VT− | 2.15 V / 1.65 V at VCC = 5.5 V - provides 0.50 V hysteresis for reliable noise margin in sensor signal conditioning |
| IOH/IOL | ±8 mA at VCC = 3.0 V - drives standard CMOS loads and small capacitive buses without buffering |
| Input Tolerance | −0.5 V to +5.5 V independent of VCC - eliminates need for external level-shifters when interfacing 5 V sensors to 3 V microcontrollers |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial control environments |
| ESD Rating | HBM: 2000 V - withstands handling and board assembly without special ESD precautions |
Pinout & Package
MC74VHC1G14DTT1G uses the TSOP-5 (Case 483) package: 3.00 mm × 1.50 mm × 0.95 mm body, 0.95 mm pitch, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect - electrically isolated; must be left floating or grounded per layout best practice |
| 2 | A | Inverting input - accepts CMOS-level signals; Schmitt-trigger thresholds reject noise below hysteresis window |
| 3 | GND | Ground reference - return path for all internal logic and output current; requires low-impedance PCB connection |
| 4 | Y | Inverted output - provides rail-to-rail CMOS-compatible output swing with 8 mA drive capability |
| 5 | VCC | Positive supply - powers internal circuitry; decoupling capacitor (0.1 µF) required within 2 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.50 V typical hysteresis at 5.5 V, enabling robust recovery from slow or noisy input edges in motor control feedback or switch debouncing |
| Over-voltage tolerant I/O | Accepts up to 5.5 V on A and Y pins regardless of VCC - allows direct connection to 5 V sensors while powered from 3.3 V MCU rail |
| IOFF partial power-down | Blocks current flow when VCC = 0 V - prevents back-powering and data corruption during system sleep or hot-swap events |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C ambient) qualification confirms reliability for automotive powertrain and body electronics applications |
| Ultra-small TSOP-5 footprint | 3.0 mm × 1.5 mm area saves PCB space in space-constrained modules like ADAS camera ECUs and smart actuators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G14DFT1G | Same electrical specs and Schmitt characteristics; SC-88A (SOT-353) package instead of TSOP-5 - 2.1 mm × 1.25 mm vs. 3.0 mm × 1.5 mm | Preferred where board space is more constrained than height; SC-88A has slightly higher thermal resistance (377 °C/W vs. 320 °C/W) | Select when footprint minimization outweighs thermal performance needs in compact consumer modules. |
| NLV74VHC1G14DTT1G | Identical pinout, function, and specs; NLV prefix denotes AEC-Q100 PPAP-capable automotive qualification with enhanced process controls | Required for production automotive programs needing full PPAP documentation and lot traceability | Choose for Tier 1 automotive designs where qualification compliance is mandatory, not optional. |
Compared with MC74VHC1G14DTT1G, the MC74VHC1G14DFT1G offers identical logic behavior in a smaller footprint but with reduced thermal dissipation capability, while the NLV74VHC1G14DTT1G adds automotive-specific process controls and documentation without altering electrical performance - making it the only drop-in replacement for safety-critical vehicle systems.

FAQ
What is the input hysteresis voltage of MC74VHC1G14DTT1G at 5.5 V supply?
The MC74VHC1G14DTT1G exhibits a typical hysteresis voltage (VH) of 0.50 V at VCC = 5.5 V, calculated as VT+ − VT− = 2.15 V − 1.65 V. This value is confirmed in the DC Electrical Characteristics table for the NLV74VHC1G14 variant, which shares identical specifications with MC74VHC1G14DTT1G. The hysteresis remains stable across −55 °C to +125 °C operating temperature.
Does MC74VHC1G14DTT1G support partial power-down mode?
Yes, MC74VHC1G14DTT1G supports IOFF partial power-down protection. When VCC = 0 V, the input and output ports enter a high-impedance state that prevents current backflow and unintended signal coupling. This feature is explicitly documented in the datasheet's "Features" section and verified in the Maximum Ratings table under IOFF parameter (1.0 µA max at 0 V).
What is the maximum propagation delay of MC74VHC1G14DTT1G at 3.3 V supply?
At VCC = 3.3 V (within 3.0–3.6 V range), the MC74VHC1G14DTT1G has a maximum propagation delay (tPLH/tPHL) of 15.0 ns with CL = 15 pF, and 18.5 ns with CL = 50 pF. These values are specified in the AC Electrical Characteristics table under "−40°C ≤ TA ≤ 85°C" conditions and apply directly to the MC74VHC1G14DTT1G variant.
Can MC74VHC1G14DTT1G safely interface a 5 V sensor to a 3.3 V microcontroller?
Yes, MC74VHC1G14DTT1G can safely interface a 5 V sensor to a 3.3 V microcontroller. Its inputs tolerate up to 5.5 V regardless of VCC, and its outputs swing rail-to-rail (0 V to 3.3 V) when powered at 3.3 V - meeting both VIH/VIL thresholds of standard 3.3 V CMOS receivers. This capability is validated in the "Input/Output Over-Voltage Tolerant" feature and Maximum Ratings table.
Is MC74VHC1G14DTT1G qualified for automotive applications?
MC74VHC1G14DTT1G is not AEC-Q100 qualified; however, its pin-compatible variant NLV74VHC1G14DTT1G carries full AEC-Q100 Grade 1 qualification and PPAP capability. The MC74VHC1G14DTT1G shares identical electrical specifications and packaging but lacks the automotive-specific process controls and documentation required for production vehicle programs.
