Product details
Overview
MC74VHC1GT14MU3TCG from onsemi is a single Schmitt-trigger inverter in a 1.0 mm × 1.0 mm UDFN6 package with TTL-level input thresholds, 4.0 ns propagation delay at 5 V, ±8 mA output drive at 3.0 V, and overvoltage tolerance up to 5.5 V - used for noise-immune signal conditioning in low-voltage industrial sensor interfaces.
For engineers reviewing the MC74VHC1GT14MU3TCG datasheet, pinout, applications, or equivalent options, key selection criteria include input threshold compatibility (TTL vs CMOS), UDFN6 footprint constraints, 2.0–5.5 V supply range, Schmitt-trigger hysteresis for slow-edge signals, and IOFF support for partial power-down systems.
Technical Context
The MC74VHC1GT14MU3TCG implements a three-stage buffered inverter architecture with Schmitt-trigger input circuitry optimized for TTL-level thresholds (VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V at VCC = 3.0–5.5 V), delivering stable switching under noisy or slow-rising input conditions. Its output stage provides rail-to-rail swing and supports 8 mA sink/source at 3.0 V.
Input and output structures are overvoltage tolerant to 5.5 V independent of VCC, enabling safe level-shifting between 3 V and 5 V domains. The IOFF feature ensures high-impedance outputs when VCC = 0 V, preventing back-drive during partial power-down sequences in mixed-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V logic domains without level shifters. |
| tPD (Typ) | 4.0 ns at VCC = 5.5 V, CL = 15 pF - enables timing-critical signal inversion in high-speed digital control paths. |
| Input Thresholds | TTL-compatible: VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V - ensures reliable recognition of standard TTL logic levels across temperature. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74-series inputs or small capacitive loads without external buffering. |
| Overvoltage Tolerance | Inputs/outputs withstand up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interconnects. |
| IOFF Support | Outputs enter high-impedance state when VCC = 0 V - prevents current backflow in hot-swap or battery-backup scenarios. |
| Hysteresis (VH) | 0.30–0.50 V (typ) - rejects noise up to ~500 mV peak-to-peak on slow or noisy input edges. |
Pinout & Package
MC74VHC1GT14MU3TCG uses a 6-pin UDFN package (1.0 mm × 1.0 mm, 0.35 mm pitch) with wettable flank side walls for automated optical inspection. Pin 1 is marked by a corner chamfer per JEDEC MO-229.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must be left floating or tied to GND for mechanical stability; no electrical function. |
| 2 | Input (A) | Inverting Schmitt-trigger input - accepts TTL-level signals; immune to noise due to hysteresis. |
| 3 | GND | Ground reference - serves as return path for all internal currents and defines logic low reference. |
| 4 | Output (Y) | Inverted, buffered output - drives downstream logic with rail-to-rail swing and ±8 mA capability. |
| 5 | No Connect (NC) | Internally unconnected - must be left floating or tied to GND; no routing required. |
| 6 | VCC | Positive supply - powers internal logic; supports 2.0–5.5 V operation with overvoltage-tolerant input protection. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level Schmitt-trigger input | Enables robust interfacing with legacy 5 V TTL outputs while operating from 3.3 V supply - no external biasing needed. |
| Overvoltage-tolerant I/O | Withstands 5.5 V on A or Y pins even when VCC = 2.0 V - simplifies voltage translation in mixed-supply PCBs. |
| IOFF partial power-down | Prevents current leakage through Y when VCC = 0 V - critical for battery-backed subsystems and hot-plug modules. |
| Ultra-small UDFN6 footprint | 1.0 mm × 1.0 mm area saves >60% board space versus SC-70-5 - ideal for space-constrained IoT sensor nodes. |
| −40 °C to +125 °C operation | Qualified for extended industrial temperature range - suitable for automotive body electronics and outdoor equipment. |
Applications
| Industrial Sensor Interface | Automotive Body Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DCKR | CMOS-input thresholds (VT+ ≈ 1.7 V @ 3.3 V); slightly higher ICC (max 10 μA vs 40 μA for MC74VHC1GT14). | Preferred where input signal originates from LVC-family logic; less tolerant of sub-1.5 V input swings. | Select when interfacing exclusively with 3.3 V CMOS outputs and lowest possible static current is critical. |
| 74AUP1G14GW,125 | Lower VCC range (0.8–3.6 V); 3.7 ns tPD at 3.3 V; no 5.5 V overvoltage tolerance. | Suitable only for single-supply ≤3.6 V systems; cannot interface 5 V signals without external protection. | Choose for ultra-low-power wearables operating strictly at 1.8 V or 3.3 V with no mixed-voltage requirements. |
Compared with SN74LVC1G14DCKR and 74AUP1G14GW,125, the MC74VHC1GT14MU3TCG uniquely combines TTL-level input compatibility, 5.5 V overvoltage tolerance, and industrial temperature range in a 1.0 mm² footprint - making it optimal for mixed-voltage industrial and automotive edge nodes.

FAQ
What is the input threshold behavior of the MC74VHC1GT14MU3TCG?
The MC74VHC1GT14MU3TCG features TTL-level Schmitt-trigger inputs with VT+ = 1.6–2.1 V and VT− = 0.35–0.6 V (depending on VCC), providing 0.3–0.5 V hysteresis. This ensures reliable switching on slow or noisy signals - unlike standard inverters, the MC74VHC1GT14MU3TCG avoids metastability when input edges cross the threshold region.
Can the MC74VHC1GT14MU3TCG safely interface a 5 V signal to a 3.3 V microcontroller?
Yes. The MC74VHC1GT14MU3TCG inputs tolerate up to 5.5 V regardless of VCC level, so a 5 V TTL signal applied to pin 2 (A) is fully compatible when the device is powered from 3.3 V. Its output also swings rail-to-rail, delivering a clean 3.3 V logic signal to the MCU - no external resistors or level shifters are needed for this use case.
Does the MC74VHC1GT14MU3TCG support partial power-down operation?
Yes. The MC74VHC1GT14MU3TCG includes IOFF circuitry that forces the output (pin 4) into a high-impedance state when VCC = 0 V. This prevents back-driving of the output node during system sleep modes or hot-swap events - a key requirement in battery-backed systems where peripherals remain active while the main supply is off.
What is the thermal performance of the MC74VHC1GT14MU3TCG in its UDFN6 package?
The MC74VHC1GT14MU3TCG in the 1.0 mm × 1.0 mm UDFN6 package (Case 517BX) has a junction-to-ambient thermal resistance (θJA) of 154 °C/W on a standard FR-4 board. At maximum rated power dissipation (812 mW), this allows a ~125 °C junction rise above ambient - consistent with its −40 °C to +125 °C operating range specification.
How does the MC74VHC1GT14MU3TCG differ from the MC74VHC1G14 variant?
The MC74VHC1GT14MU3TCG uses TTL-level input thresholds (VT+ ≈ 1.6–2.1 V), whereas the MC74VHC1G14 uses CMOS-level thresholds (VT+ ≈ 2.2–3.85 V). Both share identical packaging, output drive, propagation delay, and overvoltage tolerance. Choose MC74VHC1GT14MU3TCG when interfacing with legacy 5 V TTL sources; choose MC74VHC1G14 for CMOS-compatible signaling.
