Product details
Overview
M74VHC1GT14DFT2G-L22038 from onsemi is a single Schmitt-trigger inverter with TTL-level input thresholds, designed for 2.0 V to 5.5 V operation, delivering 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 digital interface conditioning and level-shifting between 3 V and 5 V systems.
For engineers reviewing the M74VHC1GT14DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection considerations include TTL-compatible threshold voltages (VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V), IOFF partial power-down support, SC-88A package compatibility, and guaranteed operation from −55 °C to +125 °C.
Technical Context
The M74VHC1GT14DFT2G-L22038 implements a three-stage CMOS buffer architecture with Schmitt-trigger input hysteresis (VH = 0.3–0.5 V typ) and a buffered output stage, enabling high noise immunity in industrial and automotive signal conditioning. Its input structure tolerates up to 5.5 V independent of VCC, supporting mixed-voltage interfacing.
IOFF circuitry ensures low leakage (<10 µA) when VCC = 0 V, preventing back-powering in partial power-down systems. The device exhibits no latch-up (±100 mA per JESD78 Class II) and supports hot insertion due to robust ESD protection (2 kV HBM, 1 kV CDM).
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 logic domains without level shifters. |
| Propagation Delay | 4.0 ns (typ) at 5 V, CL = 15 pF - supports high-speed signal conditioning in timing-critical paths. |
| Input Thresholds | VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V - TTL-compatible switching points ensure reliable noise rejection in legacy 5 V systems. |
| Output Drive | ±8 mA at 3.0 V - sufficient to drive multiple standard CMOS loads or small capacitive traces. |
| Over-Voltage Tolerance | Inputs/outputs rated to 5.5 V regardless of VCC - allows safe interfacing between 5 V peripherals and 3 V controllers. |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents current backflow during system sleep or hot-swap events. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
Package: SC-88A (Case 419A), 5-pin surface-mount, 2.00 mm × 1.25 mm × 0.95 mm, lead pitch 0.65 mm, Pb-free and RoHS compliant.
| 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) | TTL-level Schmitt-trigger input - accepts 0–5.5 V signals; hysteresis prevents chatter on slow or noisy edges. |
| 3 | GND | Ground reference for all internal circuitry and output stage - requires low-impedance PCB connection. |
| 4 | Output (Y) | Inverted, buffered output - drives CMOS/TTL loads with rail-to-rail swing and ±8 mA capability. |
| 5 | VCC | Positive supply pin - powers internal logic and output stage; decoupling capacitor (0.1 µF) required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level Schmitt input | VT+ = 1.6–2.1 V, VT− = 0.35–0.6 V - ensures clean switching in noisy 5 V bus environments like industrial I/O modules. |
| Over-voltage tolerant I/O | 5.5 V max on A and Y pins at any VCC - eliminates need for external clamping diodes when interfacing 5 V sensors to 3 V MCUs. |
| IOFF partial power-down | <10 µA leakage at VCC = 0 V - maintains isolation in multi-rail systems during standby without disabling upstream drivers. |
| High noise immunity | 0.3–0.5 V hysteresis window - suppresses false triggering from EMI or crosstalk in motor control feedback paths. |
| Wide temperature range | −55 °C to +125 °C operation - supports deployment in automotive engine control units and outdoor telecom equipment. |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., hall-effect switch) before feeding into a 3.3 V microcontroller ADC trigger input. IC Role / Device Role / Timing Role: Schmitt-trigger inverter acting as noise-filtering digital buffer and level shifter from 5 V sensor rail to 3.3 V logic domain.

IC Role / Device Role / Timing Role: Bidirectional voltage translation and edge sharpening component ensuring signal fidelity across mixed-supply boundaries. Use Value: Enables drop-in integration without redesigning PCB layout or adding active level translators - leverages inherent 5.5 V I/O tolerance. |
Use Scenario: Protecting backplane communication lines during live insertion of daughter cards in modular test equipment. IC Role / Device Role / Timing Role: Isolation gate that remains functional during VCC ramp-up/down sequences and prevents back-driving of powered subsystems. Use Value: IOFF support and 5.5 V tolerant pins eliminate risk of latch-up or damage during hot-plug events, reducing field failure rates. |
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+ ≈ 1.4 V @ 3.3 V), slightly higher ICC (max 10 µA vs. 40 µA), same SC-70-5 package. | Better suited for pure 3.3 V systems; lacks 5.5 V over-voltage tolerance on inputs. | Select when interfacing only within 3.3 V domains and lower quiescent current is prioritized over mixed-voltage robustness. |
| MC74VHC1G14DFT2G | CMOS-level input thresholds (VT+ = 2.2–3.85 V), identical AC/DC specs otherwise, same SC-88A package and pinout. | Designed for 3.3 V/5 V CMOS systems; not compatible with TTL-level input sources. | Choose when driving from CMOS outputs or when tighter hysteresis control (VH = 0.3–0.5 V) is needed without TTL compatibility constraints. |
Compared with SN74LVC1G14DBVR and MC74VHC1G14DFT2G, the M74VHC1GT14DFT2G-L22038 uniquely provides TTL-level input compatibility *and* 5.5 V over-voltage tolerance in the SC-88A footprint - making it the only option among the three for bridging legacy 5 V logic to modern low-voltage controllers without external protection.

FAQ
What is the input threshold voltage range for M74VHC1GT14DFT2G-L22038?
The M74VHC1GT14DFT2G-L22038 features TTL-compatible input thresholds: VT+ ranges from 1.6 V (min) to 2.1 V (max) and VT− from 0.35 V (min) to 0.6 V (max) across 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, confirming its suitability for interfacing with standard 5 V TTL logic families.
Does M74VHC1GT14DFT2G-L22038 support partial power-down operation?
Yes, the M74VHC1GT14DFT2G-L22038 supports partial power-down via its IOFF feature: when VCC = 0 V, input and output leakage remains below 10 µA (max), preventing back-current flow into powered sections of the system. This behavior is verified in the DC Electrical Characteristics table (page 5) and enables safe use in hot-swap and multi-rail architectures where subsystems power up/down independently.
What package type is used for M74VHC1GT14DFT2G-L22038?
M74VHC1GT14DFT2G-L22038 uses the SC-88A package (Case 419A), a 5-pin surface-mount outline measuring 2.00 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. Pin 1 orientation is marked with a dot or notch per the ordering information table (page 7), and the device is Pb-free and RoHS compliant - confirmed in the Marking Diagrams and Ordering Information sections of the datasheet.
Can M74VHC1GT14DFT2G-L22038 interface 5 V inputs with a 3.3 V supply?
Yes, the M74VHC1GT14DFT2G-L22038 can safely accept 5 V inputs while operating from a 3.3 V VCC due to its over-voltage tolerant input structure rated to 5.5 V regardless of supply voltage. This capability is explicitly stated in the first paragraph of the datasheet (page 1) and validated in the Maximum Ratings table (page 3), eliminating the need for external clamping or level-shifting components.
Is M74VHC1GT14DFT2G-L22038 qualified for automotive applications?
The base M74VHC1GT14DFT2G-L22038 is not automotive-qualified; however, the −Q suffix variant (e.g., M74VHC1GT14DFT2G−Q) is AEC-Q100 qualified and PPAP capable. Per the datasheet footnote on page 7, the −Q suffix denotes automotive-grade screening and unique site/control change requirements - so M74VHC1GT14DFT2G-L22038 itself is intended for industrial and commercial use unless explicitly ordered with the −Q suffix.
