Product details
Overview
MC74VHC1GT14DFT2G-Q 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 MC74VHC1GT14DFT2G-Q datasheet, pinout, applications, or equivalent options, key selection considerations include input threshold compatibility (TTL vs CMOS), IOFF partial power-down support, AEC-Q100 qualification for automotive use, and SC-88A package footprint constraints.
Technical Context
The MC74VHC1GT14DFT2G-Q implements a three-stage buffered Schmitt-trigger architecture that delivers stable switching with hysteresis (0.30–0.50 V typ) and high noise immunity. Its input structure tolerates voltages up to 5.5 V independent of VCC, enabling safe 5 V-to-3 V interfacing.
It features IOFF circuitry that disables I/O paths when VCC = 0 V, preventing back-powering and current leakage during partial power-down. The device supports −55 °C to +125 °C operating temperature 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-voltage system integration without level translators |
| tPD (typ) | 4.0 ns at 5 V, CL = 15 pF - enables high-speed signal conditioning in timing-critical paths |
| VT+ / VT− | 1.6 V / 0.35 V at 3.0 V - TTL-compatible thresholds ensure reliable recognition of standard 5 V logic levels |
| IOH / IOL | ±8 mA at 3.0 V - sufficient drive strength for fan-out to multiple CMOS loads or small capacitive traces |
| Input Over-Voltage | Up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in 5 V interface applications |
| IOFF Support | Active when VCC = 0 V - prevents current flow through I/O pins during hot-swap or power sequencing |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial environments |
Pinout & Package
MC74VHC1GT14DFT2G-Q is packaged in SC-88A (Case 419A), a 5-pin, 2.0 mm × 2.1 mm surface-mount package with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect - electrically isolated; must remain unconnected per datasheet |
| 2 | A | Inverting input - accepts TTL-level signals; over-voltage tolerant up to 5.5 V |
| 3 | GND | Ground reference - common return path for supply and signal currents |
| 4 | Y | Inverted output - Schmitt-triggered, buffered, capable of sourcing/sinking ±8 mA at 3 V |
| 5 | VCC | Positive supply - powers internal logic; supports 2.0–5.5 V with IOFF active at 0 V |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level Schmitt trigger | VT+ = 1.6 V, VT− = 0.35 V at 3 V - ensures clean switching on slow or noisy inputs without oscillation |
| Over-voltage tolerant I/O | Withstands 5.5 V on A and Y pins at any VCC - simplifies 5 V ↔ 3 V bidirectional interfacing |
| IOFF partial power-down | Blocks current flow when VCC = 0 V - essential for hot-plug and multi-rail power sequencing |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C ambient), PPAP-capable - meets automotive electronics reliability requirements |
| Ultra-small SC-88A package | 2.0 mm × 2.1 mm footprint - saves board space in compact modules like ADAS sensors and body controllers |

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-input thresholds (VT+ ≈ 1.4 V at 3.3 V); no AEC-Q100 qualification; same SC-70-5 package | Best for non-automotive consumer/industrial designs where CMOS thresholds suffice and qualification is not required | Select when cost sensitivity outweighs automotive compliance and TTL threshold matching is unnecessary |
| TC7S14F(TE85L,F) | TTL thresholds similar to MC74VHC1GT14; operates only up to 5.5 V; rated −40 °C to +85 °C; SOT-25 package | Suitable for commercial-grade applications with less stringent temp range and no PPAP requirement | Choose for cost-sensitive, non-automotive designs needing proven TTL-Schmitt performance in legacy footprint |
Compared with SN74LVC1G14DBVR and TC7S14F(TE85L,F), the MC74VHC1GT14DFT2G-Q uniquely combines AEC-Q100 Grade 1 qualification, full −55 °C to +125 °C operation, and guaranteed TTL-level thresholds - making it the only option qualified for under-hood automotive signal conditioning where temperature resilience and input compatibility are non-negotiable.

FAQ
What is the input threshold voltage specification for MC74VHC1GT14DFT2G-Q?
The MC74VHC1GT14DFT2G-Q has TTL-level input thresholds: VT+ = 1.6 V (min) and VT− = 0.35 V (max) at VCC = 3.0 V, with hysteresis of 0.30 V (typ). These values are confirmed in the DC Electrical Characteristics table for MC74VHC1GT14 on page 5 of the datasheet and enable reliable recognition of standard 5 V logic signals even when powered from 3 V supplies.
Is MC74VHC1GT14DFT2G-Q pin-compatible with MC74VHC1G14DFT2G-Q?
No - although both share the SC-88A package and identical pin count, the MC74VHC1GT14DFT2G-Q and MC74VHC1G14DFT2G-Q have different input threshold characteristics (TTL vs CMOS) and distinct marking codes (VC vs VA). Their functional behavior differs significantly in mixed-voltage interface scenarios, so substitution requires validation of signal threshold compatibility in the target application.
Does MC74VHC1GT14DFT2G-Q support partial power-down operation?
Yes - the MC74VHC1GT14DFT2G-Q includes IOFF circuitry that actively disables input and output paths when VCC = 0 V, limiting leakage current to ≤10 µA. This feature prevents back-driving and unintended current flow during hot insertion or multi-rail power sequencing, as specified in the DC Electrical Characteristics table on page 5.
What is the maximum operating temperature range for MC74VHC1GT14DFT2G-Q?
The MC74VHC1GT14DFT2G-Q is rated for −55 °C to +125 °C operating ambient temperature and is AEC-Q100 qualified for Grade 1 automotive use. This extended range is verified per the Recommended Operating Conditions table on page 3 and supports deployment in engine bay, transmission control, and other high-temperature under-hood locations.
Which package type is used by MC74VHC1GT14DFT2G-Q?
The MC74VHC1GT14DFT2G-Q uses the SC-88A package (Case 419A), a 5-pin, 2.0 mm × 2.1 mm surface-mount outline with 0.65 mm lead pitch. This is explicitly listed in the Ordering Information table on page 7, where "DFT2G" suffix denotes SC-88A packaging with Q-grade automotive qualification.
