Product details
Overview
MC74HC1G14DFT2G-L22038 from onsemi is a single high-speed CMOS inverter with Schmitt-trigger input, designed for noise-immune signal conditioning in digital logic interfaces. It operates from 2.0 V to 6.0 V, delivers balanced propagation delays (tPLH = tPHL = 7 ns typ at 5 V), supports ±2 mA output drive, and is housed in SC-88A (SOT-353) package for space-constrained PCBs in industrial sensor interface circuits.
For engineers reviewing the MC74HC1G14DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.57 V min at 4.5 V), input threshold symmetry (VT+ = 3.15 V, VT− = 1.35 V at 4.5 V), thermal resistance (377 °C/W), and Pb-free RoHS-compliant packaging.
Technical Context
The MC74HC1G14DFT2G-L22038 implements a five-stage CMOS inverter chain with Schmitt-trigger input stage to reject slow-rising or noisy signals, enabling reliable edge detection in low-voltage microcontroller reset circuits and encoder signal debouncing. Its buffer output stage provides high noise immunity and symmetrical output impedance (IOH = IOL = 2 mA).
It is fabricated using silicon gate CMOS technology with chip complexity under 100 FETs, supporting operation across −55 °C to +125 °C and featuring latchup immunity of ±100 mA per JESD78 Class II. The device exhibits no input rise/fall time limits across its full 2.0–6.0 V supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter-with-Schmitt-input applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Lower VCC range (1.65–5.5 V); higher speed (4.5 ns typ at 3.3 V); 3.3 V optimized. | Better suited for mixed-voltage 3.3 V/1.8 V systems; less margin at 5 V or below 2 V. | Select when operating primarily at 3.3 V with strict timing budgets; verify VCC stability in 5 V rails. |
| 74AHC1G14GW,125 | Higher drive strength (±8 mA); wider VCC (2–5.5 V); slightly lower hysteresis (0.45 V min at 4.5 V). | Preferred for driving heavier capacitive loads (>30 pF) or longer traces; reduced noise margin vs. MC74HC1G14. | Choose when output loading exceeds 15 pF or when faster transition times (tTLH/tTHL = 3.5 ns) are critical. |
Compared with SN74LVC1G14DBVR and 74AHC1G14GW,125, the MC74HC1G14DFT2G-L22038 offers superior hysteresis and broader supply tolerance (2.0–6.0 V), making it optimal for legacy 5 V industrial designs and mixed-voltage brown-out detection where noise immunity outweighs raw speed.

FAQ
What is the maximum operating temperature for MC74HC1G14DFT2G-L22038?
The MC74HC1G14DFT2G-L22038 is rated for continuous operation from −55 °C to +125 °C, validated per JEDEC JESD22-A108. This makes it suitable for under-hood automotive applications and industrial control cabinets where ambient temperatures exceed 85 °C. Derating is not required within this full range.
Does MC74HC1G14DFT2G-L22038 support 1.8 V logic levels?
No - MC74HC1G14DFT2G-L22038 has a minimum VCC of 2.0 V per its Recommended Operating Conditions table. At 1.8 V, the device may fail to meet specified propagation delay, hysteresis, or output voltage levels. For 1.8 V systems, consider SN74LVC1G14DBVR instead.
Is pin 2 of MC74HC1G14DFT2G-L22038 internally connected?
No - pin 2 of MC74HC1G14DFT2G-L22038 is explicitly designated N/C (No Connection) in the datasheet pin assignment and functional diagram. It must remain unconnected on the PCB; no pull-up, pull-down, or routing is permitted.
What is the typical hysteresis voltage of MC74HC1G14DFT2G-L22038 at 5.0 V supply?
At VCC = 5.0 V, the MC74HC1G14DFT2G-L22038 exhibits a typical hysteresis voltage (VH) of 0.67 V, calculated as VT+ − VT− = 3.15 V − 1.35 V. This value is confirmed in the DC Electrical Characteristics table under "Hysteresis Voltage" for VCC = 4.5 V (closest tested condition).
Can MC74HC1G14DFT2G-L22038 drive an LED directly?
Yes - with appropriate current limiting. The MC74HC1G14DFT2G-L22038 can sink up to 12.5 mA (IOL max), sufficient for low-current indicator LEDs. For a red LED (VF ≈ 1.8 V) at 5 V, a 270 Ω series resistor yields ~12 mA. Do not exceed IOL or IOH ratings per pin.
