Product details
Overview
MC74HC1G14DFT1G-F22038 from onsemi is a single high-speed CMOS Schmitt-trigger inverter in SC-88A (SOT-353) package, operating from 2.0 V to 6.0 V, with 7 ns typical propagation delay at 5 V, ±2 mA output drive, and hysteresis of 0.40 V (typ) at 4.5 V - used for noise-immune signal conditioning in sensor interface and power-on reset circuits.
For engineers reviewing the MC74HC1G14DFT1G-F22038 datasheet, pinout, applications, or equivalent options, key selection criteria include input hysteresis voltage (VT+ = 3.15 V, VT− = 1.35 V at VCC = 4.5 V), symmetrical output impedance, balanced tPLH/tPHL delays, and SC-88A thermal resistance (377 °C/W).
Technical Context
The MC74HC1G14DFT1G-F22038 implements a single-stage Schmitt-trigger input followed by buffered CMOS inverter logic, enabling clean digital signal regeneration from slow or noisy analog waveforms. Its internal design ensures stable switching thresholds independent of input slew rate.
It supports rail-to-rail operation across −55 °C to +125 °C, with guaranteed hysteresis (0.40–0.74 V) and low ICC (≤1 µA max at 25 °C), making it suitable for battery-powered systems requiring reliable edge detection without external RC networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 6.0 V - supports wide supply flexibility including 3.3 V and 5 V logic domains |
| tPD (Typ) | 7 ns at VCC = 5 V, CL = 15 pF - enables use in sub-100 MHz timing-critical signal paths |
| VT+ / VT− | 3.15 V / 1.35 V at VCC = 4.5 V - provides 1.8 V hysteresis for robust noise rejection in industrial environments |
| IOUT | ±2 mA - sufficient to directly drive LED indicators or small logic loads without buffering |
| ICC (Max) | 1 µA at TA = 25 °C - enables ultra-low static power in always-on monitoring circuits |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood and industrial control applications |
| Package | SC-88A (SOT-353), 5-pin - compact 2.1 mm × 1.25 mm footprint for space-constrained PCB layouts |
Pinout & Package
MC74HC1G14DFT1G-F22038 uses the SC-88A (SOT-353) surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal logic and output stages |
| 2 | N/C | No internal connection - must be left floating or tied to GND per layout best practice |
| 3 | A | Schmitt-trigger input - accepts slow-rising signals and rejects noise below hysteresis window |
| 4 | VCC | Positive supply rail - decoupling capacitor (0.1 µF) recommended within 2 mm |
| 5 | Y | Inverted output - drives complementary logic or active-low enable lines with symmetrical rise/fall times |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable waveform shaping of slow or noisy inputs (e.g., mechanical switch bounce, thermistor outputs) |
| Balanced tPLH/tPHL | Ensures predictable timing margins in clockless synchronous interfaces like I²C pull-up recovery |
| Symmetrical IOH/IOL | Supports bidirectional signal inversion without level-shifting circuitry in mixed-voltage systems |
| Low ICC (≤1 µA) | Reduces quiescent current in battery-backed real-time clock supervisors and wake-up detectors |
| Pb-free, Halogen-free | Meets IPC-J-STD-609A Class 1 and RoHS Directive 2011/65/EU requirements for green manufacturing |

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 | Lower VCC min (1.65 V), higher speed (4.5 ns typ), but narrower hysteresis (0.25 V typ at 3.3 V) | Better suited for low-voltage portable devices; less effective in noisy industrial settings | Select when operating below 2.0 V or requiring faster response than MC74HC1G14DFT1G-F22038 offers |
| 74AUP1G14GW,125 | Ultra-low ICC (0.9 µA max), wider temp range (−40 °C to +125 °C), but reduced drive (±1 mA) | Optimized for energy harvesting and long-life battery systems where drive strength is secondary | Select when minimizing standby current is critical and load capacitance ≤15 pF |
Compared with SN74LVC1G14DBVR and 74AUP1G14GW,125, the MC74HC1G14DFT1G-F22038 delivers superior noise immunity via larger hysteresis and maintains robust drive capability across extended temperature extremes, making it preferred for industrial and automotive signal conditioning.

FAQ
What is the maximum operating temperature for MC74HC1G14DFT1G-F22038?
The MC74HC1G14DFT1G-F22038 is rated for operation from −55 °C to +125 °C, meeting extended temperature requirements for under-hood automotive and industrial control applications. This rating is verified per JEDEC JESD22-A108 and confirmed in the Absolute Maximum Ratings table of the official datasheet (Rev. 20, Jan 2026).
Does MC74HC1G14DFT1G-F22038 support 3.3 V logic systems?
Yes, MC74HC1G14DFT1G-F22038 fully supports 3.3 V operation: VCC min is 2.0 V, and all AC/DC parameters-including VT+, VT−, tPD, and IOUT-are specified down to 2.0 V. At 3.3 V, typical hysteresis is 0.50 V and propagation delay is 9 ns (CL = 15 pF), ensuring reliable interfacing with 3.3 V microcontrollers and FPGAs.
What is the function of Pin 2 (N/C) on MC74HC1G14DFT1G-F22038?
Pin 2 of MC74HC1G14DFT1G-F22038 is internally not connected (N/C). It must not be tied to VCC or driven externally. Per onsemi's package documentation and pin assignment diagram, this terminal has no electrical function and should remain unconnected or optionally grounded for mechanical stability-no performance impact results from either choice.
Can MC74HC1G14DFT1G-F22038 drive an LED directly?
MC74HC1G14DFT1G-F22038 can drive a low-current LED (e.g., 2 mA, 1.8 V forward voltage) in sink configuration using Y (Pin 5) and a series resistor, provided VCC ≥ 3.0 V. Its guaranteed IOL = 2 mA at VOL ≤ 0.33 V (VCC = 4.5 V) supports this use case, but continuous DC drive is limited by thermal dissipation in the SC-88A package (max PD = 332 mW).
Is MC74HC1G14DFT1G-F22038 pin-compatible with other SC-88A inverters?
MC74HC1G14DFT1G-F22038 shares the SC-88A (SOT-353) 5-pin outline and identical pinout (GND–N/C–A–VCC–Y) with other onsemi single-gate logic devices like MC74HC1G00 and MC74HC1G02. However, functional compatibility requires verification of truth tables and drive strength - it is not a drop-in replacement for non-inverting or multi-input logic functions.
