Product details
Overview
MC74VHC1GT14MU1TCG from onsemi is a single Schmitt-trigger inverter with TTL-level input thresholds, designed for 2.0 V to 5.5 V operation, 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 in noise-prone signal conditioning and level-shifting between 3 V and 5 V logic domains.
For engineers reviewing the MC74VHC1GT14MU1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include TTL-compatible threshold levels (VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V), UDFN6-6 (1.45 × 1.0 mm, 0.5 mm pitch) package, IOFF partial power-down support, and 125 °C maximum operating temperature for industrial environments.
Technical Context
The MC74VHC1GT14MU1TCG implements a three-stage CMOS buffer architecture with Schmitt-trigger input hysteresis (VH = 0.3–0.5 V typ), enabling robust noise immunity in slow-rising or noisy digital signals. Its input structure tolerates up to 5.5 V regardless of VCC, supporting mixed-voltage interfacing.
Output stages feature over-voltage tolerance during VCC = 0 V and allow safe hot insertion. The device supports IOFF mode for partial power-down protection, preventing back-drive current when VCC is unpowered - critical for system-level power sequencing in embedded controllers and sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables direct use across 3.3 V and 5 V systems without level translators. |
| tPD (typ) | 4.0 ns at VCC = 5 V, CL = 15 pF - ensures fast signal inversion for timing-critical edge detection. |
| Input Thresholds | VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V (TTL-compatible) - guarantees reliable switching with standard 5 V TTL outputs. |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents unintended current paths during power-down sequences. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74-series inputs or small capacitive loads (≤50 pF). |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood applications. |
| ESD Rating | HBM: 2000 V - provides baseline handling robustness in automated assembly and field service. |
Pinout & Package
MC74VHC1GT14MU1TCG is housed in a 6-pin UDFN package (1.45 mm × 1.0 mm, 0.5 mm pitch, case 517AQ), featuring an exposed thermal pad and no lead finish restrictions (Pb-free, RoHS compliant). Pin 1 is marked by a dot or beveled corner per JEDEC MO-229.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect terminal - electrically isolated; must remain unconnected per datasheet. |
| 2 | A | Inverting input - accepts TTL-level signals; hysteresis improves noise margin on slow edges. |
| 3 | GND | Ground reference - serves as return path for all internal logic and output currents. |
| 4 | Y | Inverted output - actively driven high/low; supports 5.5 V over-voltage tolerance even when VCC = 0 V. |
| 5 | NC | No-connect terminal - electrically isolated; must remain unconnected per datasheet. |
| 6 | VCC | Positive supply - powers internal circuitry; IOFF protection activates when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level Schmitt input | VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V - ensures compatibility with legacy 5 V TTL outputs while rejecting noise. |
| Over-voltage tolerant I/O | Inputs/outputs withstand 5.5 V independent of VCC - eliminates need for external clamping diodes in mixed-voltage systems. |
| IOFF partial power-down | Leakage <10 µA when VCC = 0 V - prevents back-powering of powered subsystems during sleep or reset states. |
| High noise immunity | 0.3–0.5 V hysteresis window - suppresses false triggering from EMI, crosstalk, or slow signal transitions. |
| Small-footprint UDFN6 | 1.45 × 1.0 mm, 0.5 mm pitch - saves board space in compact IoT sensors, wearables, and portable instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | CMOS-level thresholds (VT+ ≈ 1.7 V, VT− ≈ 0.7 V), same UDFN6 package, 3.3 V optimized. | Better suited for pure 3.3 V systems; less compatible with 5 V TTL sources than MC74VHC1GT14MU1TCG. | Select when interfacing exclusively with LVC-family logic or low-VCC designs where TTL thresholds are unnecessary. |
| 74AUP1G14GW,125 | Ultra-low power (ICC < 0.9 µA), smaller XSON6 (1.0 × 1.0 mm), but only rated to 3.6 V VCC max. | Limited to battery-powered, low-noise applications; cannot interface 5 V signals or operate above 3.6 V. | Choose for energy-constrained wearable or sensor nodes where 5 V compatibility is not required. |
Compared with SN74LVC1G14DBVR and 74AUP1G14GW,125, the MC74VHC1GT14MU1TCG uniquely combines TTL-level input compatibility, 5.5 V absolute maximum ratings, and AEC-Q100 qualification - making it the only option among the three suitable for mixed-voltage industrial control and automotive body electronics.

FAQ
What is the input threshold voltage range for MC74VHC1GT14MU1TCG?
The MC74VHC1GT14MU1TCG features TTL-compatible input thresholds: VT+ ranges from 1.6 V to 2.1 V and VT− from 0.35 V to 0.6 V across VCC = 3.0 V to 5.5 V and temperature (−55 °C to +125 °C). This ensures reliable recognition of standard 5 V TTL logic levels while maintaining hysteresis for noise rejection - a defining characteristic of the MC74VHC1GT14MU1TCG.
Does MC74VHC1GT14MU1TCG support partial power-down operation?
Yes, the MC74VHC1GT14MU1TCG supports IOFF partial power-down protection. When VCC = 0 V, input and output leakage remains below 10 µA, preventing back-current flow into powered sections of the system. This behavior is explicitly characterized in the datasheet and applies to the MC74VHC1GT14MU1TCG under all operating temperatures.
What package type and dimensions does MC74VHC1GT14MU1TCG use?
The MC74VHC1GT14MU1TCG uses the UDFN6 package (case 517AQ): 1.45 mm × 1.0 mm footprint, 0.5 mm pin pitch, and 0.55 mm max height. It includes an exposed thermal pad and complies with JEDEC MO-229. This package is confirmed in the ordering table and mechanical drawings specific to the MC74VHC1GT14MU1TCG variant.
Can MC74VHC1GT14MU1TCG interface 5 V signals while powered from 3.3 V?
Yes, the MC74VHC1GT14MU1TCG can safely accept 5 V input signals while operating from a 3.3 V supply. Its inputs are over-voltage tolerant up to 5.5 V regardless of VCC, and outputs maintain 5.5 V tolerance even when VCC = 0 V. This capability is fully specified and tested for the MC74VHC1GT14MU1TCG across its full temperature range.
Is MC74VHC1GT14MU1TCG qualified for automotive applications?
Yes, the MC74VHC1GT14MU1TCG is AEC-Q100 qualified and PPAP capable when ordered with the "−Q" suffix (e.g., MC74VHC1GT14MU1TCG-Q). While the base part number MC74VHC1GT14MU1TCG shares identical electrical and thermal specifications, automotive qualification requires the −Q variant - confirmed in the datasheet's ordering information and revision notes.
