Product details
Overview
MC74VHC1GT04DFT3G from onsemi is a single-channel TTL-input CMOS inverter in SC-88A (SOT-353) package, operating from 2.0 V to 5.5 V supply, delivering 3.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and input/output overvoltage tolerance up to 5.5 V - used for level-shifting between 3 V and 5 V logic domains in portable instrumentation interfaces.
For engineers reviewing the MC74VHC1GT04DFT3G datasheet, pinout, applications, or equivalent options, key selection criteria include TTL-compatible input thresholds (VIH = 1.4 V min at 3 V), IOFF partial power-down support, SC-88A footprint compatibility, and AEC-Q100 qualification availability via −Q suffix variants.
Technical Context
The MC74VHC1GT04DFT3G implements a single unbuffered inverting gate with TTL-level input thresholds (VIH = 1.4 V @ VCC = 3.0 V; VIL = 0.45 V @ VCC = 3.0 V), enabling direct interfacing with legacy 5 V TTL outputs while powered from 3 V supplies. Its input structure tolerates up to 5.5 V regardless of VCC, supporting mixed-voltage system design.
Output stages feature overvoltage tolerance when VCC = 0 V and during hot insertion, and IOFF functionality prevents back-driving current during partial power-down. The device uses sub-100 FET CMOS logic with no internal pull-ups or Schmitt-trigger hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply systems and battery-powered 3 V operation without level shifters. |
| tPD (Typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal inversion in timing-critical paths like clock buffering or enable control. |
| IOH/IOL | ±8 mA at VCC = 3.0 V - drives standard CMOS loads and small capacitive buses without external buffers. |
| Input Thresholds | VIH = 1.4 V, VIL = 0.45 V @ VCC = 3.0 V - matches TTL logic levels, allowing direct connection to 74LS/74F outputs. |
| Overvoltage Tolerance | Inputs/outputs withstand 5.5 V independent of VCC - eliminates need for external clamping diodes in 5 V-to-3 V interface circuits. |
| IOFF Support | Active when VCC = 0 V - prevents current leakage through powered-down sections, critical for low-power sleep modes. |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments. |
Pinout & Package
MC74VHC1GT04DFT3G is packaged in SC-88A (SOT-353), a 5-pin, 2.0 mm × 2.1 mm surface-mount package with 0.65 mm pitch, optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 | Input (A) | TTL-compatible input node accepting 0–5.5 V signals; threshold set for 3 V supply compatibility. |
| 3 | GND | Ground reference for both logic and power domains; required for stable noise margin and ESD protection path. |
| 4 | Output (Y) | Inverted logic output with rail-to-rail swing and ±8 mA drive capability at 3 V. |
| 5 | VCC | Positive supply input (2.0–5.5 V); powers internal logic and defines output voltage levels. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-input compatibility | VIH/VIL thresholds match legacy 74LS family, enabling drop-in replacement in existing 5 V logic designs powered from 3 V rails. |
| Overvoltage-tolerant I/O | Withstands 5.5 V on A or Y pins regardless of VCC - allows safe interfacing between 5 V microcontrollers and 3 V peripherals without external protection. |
| IOFF partial power-down | Blocks current flow when VCC = 0 V - essential for maintaining isolation in multi-rail systems during standby or reset sequences. |
| SC-88A footprint | 2.0 mm × 2.1 mm, 0.65 mm pitch - fits high-density layouts where space is constrained, such as wearables and sensor modules. |
| AEC-Q100 option | −Q suffix variants are automotive-qualified (Grade 1) with PPAP documentation - suitable for body electronics and infotainment subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | CMOS-input thresholds (VIH = 2.1 V @ 3 V), slightly higher ICC (max 10 µA vs. 1 µA), same SC-70-5 package. | Requires 3 V logic source; not suitable for direct 5 V TTL input without external conditioning. | Select when interfacing only with 3 V CMOS sources and lower static current is prioritized. |
| 74AUP1G04GW,125 | Ultra-low power (ICC = 0.9 µA typ), wider VCC range (0.8–3.6 V), but max VIO = 3.6 V - no 5.5 V overvoltage tolerance. | Not usable in 5 V-to-3 V translation; limited to single-supply ≤3.6 V systems. | Choose for battery-operated devices needing minimal quiescent current and no mixed-voltage operation. |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the MC74VHC1GT04DFT3G uniquely combines TTL input compatibility, 5.5 V overvoltage tolerance, and SC-88A packaging - making it the only option among the three capable of safe, direct 5 V signal interfacing while powered from 3 V without external components.

FAQ
What is the input voltage threshold behavior of MC74VHC1GT04DFT3G?
The MC74VHC1GT04DFT3G features TTL-compatible input thresholds: VIH is 1.4 V minimum and VIL is 0.45 V maximum at VCC = 3.0 V. This allows direct interfacing with legacy 5 V TTL outputs while operating from a 3 V supply. Unlike CMOS-input inverters, the MC74VHC1GT04DFT3G does not require VCC/2 thresholds - its defined VIH/VIL values are fixed per supply voltage and published in Table 5 of the datasheet.
Does MC74VHC1GT04DFT3G support partial power-down operation?
Yes, MC74VHC1GT04DFT3G supports IOFF - a partial power-down feature that disables input and output circuitry when VCC = 0 V. This prevents current backflow from live inputs or outputs into a powered-down system section. The datasheet specifies IOFF leakage ≤10 µA under these conditions, ensuring safe operation in multi-rail systems during sleep or reset states.
What package type is used for MC74VHC1GT04DFT3G and what are its dimensions?
MC74VHC1GT04DFT3G uses the SC-88A (also known as SOT-353) package: a 5-pin, surface-mount outline measuring 2.0 mm × 2.1 mm with 0.65 mm lead pitch. Pin 1 is marked by a dot or notch, and the package is Pb-free, halogen-free, and RoHS compliant per the datasheet's ordering information table.
Can MC74VHC1GT04DFT3G safely interface a 5 V signal to a 3 V microcontroller?
Yes, MC74VHC1GT04DFT3G can safely interface a 5 V signal to a 3 V microcontroller. Its inputs tolerate up to 5.5 V regardless of VCC, and its TTL-level thresholds ensure correct logic interpretation when driven by 5 V sources. The output swings rail-to-rail (0 V to 3 V), matching the microcontroller's input requirements - eliminating need for external level-shifting components.
Is MC74VHC1GT04DFT3G qualified for automotive applications?
The base MC74VHC1GT04DFT3G is not automotive-qualified, but onsemi offers −Q suffix variants (e.g., MC74VHC1GT04DFT3G−Q) that are AEC-Q100 Grade 1 qualified and PPAP-capable. These versions undergo additional stress testing and process controls for automotive use, including operation from −40 °C to +125 °C and enhanced reliability screening - confirmed in the datasheet's "−Q Suffix" feature description.
