Product details
Overview
M74VHC1GT14DFT1G-L22038 from onsemi is a single Schmitt-trigger inverter with TTL-level input thresholds, designed for level-shifting and noise-immune signal conditioning in 2.0 V to 5.5 V systems. It features 4.0 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, over-voltage tolerant inputs/outputs up to 5.5 V, and IOFF partial power-down protection - enabling robust interfacing between 3 V and 5 V logic domains in industrial control I/O modules.
For engineers reviewing the M74VHC1GT14DFT1G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include TTL-compatible hysteresis thresholds (VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V), SC-88A package compatibility, and guaranteed operation across −55 °C to +125 °C.
Technical Context
The M74VHC1GT14DFT1G-L22038 implements a three-stage CMOS buffer architecture with Schmitt-trigger input and buffered output, delivering high noise immunity and stable switching. Its TTL-level input thresholds (VT+ ≈ 1.6–2.1 V, VT− ≈ 0.35–0.6 V at VCC = 3.0–5.5 V) distinguish it from the CMOS-threshold MC74VHC1G14 variant.
Input and output structures tolerate voltages up to 5.5 V independent of VCC, supporting mixed-voltage interface applications. IOFF functionality ensures low leakage (<10 µA) when VCC = 0 V, enabling hot-insertion and partial power-down system designs.
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 rails without level translators. |
| tPD (Typ) | 4.0 ns at VCC = 5 V, CL = 15 pF - enables timing-critical signal inversion in high-speed digital interfaces. |
| VT+ / VT− | 1.6–2.1 V / 0.35–0.6 V at VCC = 3.0–5.5 V - TTL-compatible hysteresis prevents chatter on slow or noisy inputs. |
| IOH / IOL | ±8 mA at VCC = 3.0 V - sufficient drive strength to fan out to multiple standard logic inputs. |
| Input/Output Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing of 5 V signals into 3 V systems without external clamping. |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents back-powering and signal corruption during partial power-down states. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and outdoor embedded applications. |
Pinout & Package
Package: SC-88A (Case 419A), 5-pin surface-mount package measuring 2.1 mm × 2.0 mm × 1.0 mm, lead pitch 0.65 mm, RoHS-compliant and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect terminal - must be left floating or grounded per layout guidelines; not internally bonded. |
| 2 | A | Inverting Schmitt-trigger input - accepts TTL-level signals; tolerant to 5.5 V regardless of VCC. |
| 3 | GND | Ground reference - return path for supply and signal currents; requires low-impedance PCB connection. |
| 4 | Y | Inverted output - provides rail-to-rail CMOS-compatible output with ±8 mA drive capability at 3 V. |
| 5 | VCC | Positive supply - powers internal circuitry; supports 2.0–5.5 V operation with IOFF active at 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level Schmitt trigger | VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V - eliminates false triggering on slow-rise or EMI-contaminated signals in industrial environments. |
| Over-voltage tolerant I/O | Withstands 5.5 V on A and Y pins at any VCC (including 0 V) - enables direct 5 V ↔ 3 V translation without external resistors or diodes. |
| IOFF partial power-down | Leakage <10 µA when VCC = 0 V - maintains isolation and prevents bus contention during sleep or hot-swap events. |
| High noise immunity | Minimum hysteresis = 0.3 V (typ), up to 0.81 V (max) - rejects transient noise up to ±400 mV on input lines. |
| Wide temperature range | Specified from −55 °C to +125 °C - validated for use in automotive engine control units and industrial motor drives. |

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-threshold (VT+ ≈ 1.4–2.0 V), lower ICC (1 µA max), same SC-70-5 package. | Optimized for ultra-low static power; less hysteresis margin than M74VHC1GT14DFT1G-L22038 in noisy environments. | Select when minimizing quiescent current is critical and input noise is controlled; not drop-in due to threshold mismatch. |
| MC74VHC1G14DFT1G | CMOS-level input thresholds (VT+ = 2.2–3.85 V), identical package, pinout, and AC specs. | Requires higher input voltage swing; unsuitable for direct TTL or 5 V → 3 V interface without pull-up. | Choose only when interfacing with CMOS sources; M74VHC1GT14DFT1G-L22038 is preferred for legacy TTL or mixed-voltage systems. |

FAQ
What is the input threshold voltage range for M74VHC1GT14DFT1G-L22038?
The M74VHC1GT14DFT1G-L22038 has TTL-level input thresholds: VT+ ranges from 1.6 V to 2.1 V and VT− from 0.35 V to 0.6 V, depending on VCC (3.0–5.5 V) and temperature (−55 °C to +125 °C). These values are specified in the DC Electrical Characteristics table for MC74VHC1GT14 on page 5 of the datasheet and confirm its compatibility with standard TTL logic families.
Does M74VHC1GT14DFT1G-L22038 support 5 V to 3.3 V level translation?
Yes, the M74VHC1GT14DFT1G-L22038 supports bidirectional level translation: its inputs and outputs tolerate up to 5.5 V regardless of VCC, allowing 5 V signals to safely drive the A input while powered from 3.3 V, and the Y output to drive 5 V logic loads. This capability is explicitly confirmed in the "Inputs/Outputs Over-Voltage Tolerant" feature and Maximum Ratings table.
What package type is used for M74VHC1GT14DFT1G-L22038?
The M74VHC1GT14DFT1G-L22038 uses the SC-88A package (Case 419A), a 5-pin surface-mount outline measuring 2.1 mm × 2.0 mm × 1.0 mm with 0.65 mm lead pitch. This is confirmed in the Ordering Information table (page 7) where "MC74VHC1GT14DFT1G" maps to SC-88A/DF suffix and Case 419A.
Is M74VHC1GT14DFT1G-L22038 qualified for automotive applications?
The base M74VHC1GT14DFT1G-L22038 is not automotive-qualified; however, the −Q suffix variant (e.g., MC74VHC1GT14DFT1G-Q) is AEC-Q100 qualified and PPAP capable. The datasheet states "−Q Suffix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements", confirming that qualification applies only to designated −Q parts, not the standard-grade M74VHC1GT14DFT1G-L22038.
What is the maximum propagation delay for M74VHC1GT14DFT1G-L22038 at 3.3 V?
At VCC = 3.3 V (within 3.0–3.6 V range), the maximum propagation delay (tPLH/tPHL) for M74VHC1GT14DFT1G-L22038 is 15.0 ns (CL = 15 pF) and 18.5 ns (CL = 50 pF), as specified in the AC Electrical Characteristics table on page 5. These values apply across −40 °C ≤ TA ≤ +85 °C and are guaranteed by design.
Does M74VHC1GT14DFT1G-L22038 have IOFF functionality?
Yes, the M74VHC1GT14DFT1G-L22038 includes IOFF (power-off protection): when VCC = 0 V, input and output leakage current is limited to ≤10 µA, preventing back-driving of powered-down buses. This is documented in the Features list ("IOFF Supports Partial Power Down Protection") and verified in the DC Electrical Characteristics table (IOFF parameter, page 5).
