Product details
Overview
M74VHC1GT02DFT1G-L22038 from onsemi is a single 2-input NOR gate logic IC with TTL-level input thresholds, designed for 2.0 V to 5.5 V operation, delivering 3.5 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 level-shifting interfaces between 3 V and 5 V digital subsystems.
For engineers reviewing the M74VHC1GT02DFT1G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include input threshold compatibility (TTL vs CMOS), IOFF partial power-down support, SC-88A package footprint, and guaranteed operation across −55 °C to +125 °C industrial temperature range.
Technical Context
The M74VHC1GT02DFT1G-L22038 implements standard positive-logic NOR functionality (Y = NOT(A OR B)) using advanced high-speed CMOS process technology. Its TTL-compatible input thresholds (VIH = 1.4 V min at 3.0 V VCC; VIL = 0.45 V max) enable direct interfacing with legacy 5 V TTL outputs while operating from 3 V supplies.
Input and output structures are over-voltage tolerant to 5.5 V independent of VCC, supporting mixed-voltage domain interconnects. The IOFF feature ensures high-impedance outputs during power-down (VCC = 0 V), preventing back-driving and bus contention in partial-power-down systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply systems and battery-backed 3.3 V logic rails |
| tPD (Typ) | 3.5 ns at 5 V, CL = 15 pF - enables timing-critical glue logic in high-speed control paths |
| IOH/IOL | ±8 mA at 3.0 V - drives standard 74-series TTL loads or multiple CMOS inputs without buffering |
| VIH/VIL | 1.4 V / 0.45 V min/max at 3.0 V - TTL-compatible thresholds ensure reliable recognition of 5 V logic levels |
| Over-Voltage Tolerance | Inputs/outputs withstand 5.5 V regardless of VCC - eliminates external clamping diodes in mixed-voltage interfaces |
| IOFF Support | Active when VCC = 0 V - prevents current leakage and signal corruption during hot-swap or partial power-down |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor embedded applications |
Pinout & Package
Package: SC-88A (Case 419A), 5-pin surface-mount, 2.00 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second NOR input; accepts TTL- or CMOS-level signals up to 5.5 V |
| 2 | Input A | Primary NOR input; electrically identical to Pin 1, fully interchangeable |
| 3 | GND | Ground reference; must be connected to system ground plane for noise immunity and ESD protection |
| 4 | Output Y | NOR result (Y = NOT(A OR B)); actively driven high/low or high-Z when IOFF active |
| 5 | VCC | Positive supply; powers internal logic and output stage; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Level Input Thresholds | Enables direct connection to 5 V TTL outputs without level translators in 3 V systems |

| −55 °C to +125 °C Operation | Validated performance across full industrial and automotive under-hood temperature ranges |
| SC-88A Small Footprint | 0.65 mm pitch, 2.00 × 1.25 mm body - saves PCB area in space-constrained modules and wearables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G02DFT1G | CMOS-level input thresholds (VIH = 2.1 V min at 3.0 V), not TTL-compatible | Requires 3 V logic sources; unsuitable for direct 5 V TTL interfacing | Select when interfacing only with 3 V CMOS outputs and lower input threshold noise immunity is acceptable |
| SN74LVC1G02DBVR | Wider VCC range (1.65–5.5 V); higher drive (±32 mA at 3.3 V); no IOFF | Lacks power-down isolation; may require external isolation in hot-swap systems | Prefer for higher-drive, ultra-low-voltage (1.8 V) applications where IOFF is not required |
Compared with MC74VHC1G02DFT1G, M74VHC1GT02DFT1G-L22038 offers guaranteed TTL-level recognition critical for legacy interoperability; versus SN74LVC1G02DBVR, it trades drive strength for robust IOFF and tighter industrial temperature compliance - making it optimal for mixed-voltage, partial-power-down embedded control.

FAQ
What is the input voltage threshold behavior of the M74VHC1GT02DFT1G-L22038?
The M74VHC1GT02DFT1G-L22038 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 reliable recognition of standard 5 V TTL output levels while operating from a 3 V supply, eliminating the need for external level-shifting circuitry in mixed-voltage designs.
Does the M74VHC1GT02DFT1G-L22038 support partial power-down operation?
Yes, the M74VHC1GT02DFT1G-L22038 includes IOFF circuitry that places outputs in high-impedance state when VCC = 0 V. This prevents back-current flow and bus contention during hot-insertion or partial system power-down - a critical feature for modular systems and battery-backed subsystems where not all rails are simultaneously active.
Which package does the M74VHC1GT02DFT1G-L22038 use, and what are its dimensions?
The M74VHC1GT02DFT1G-L22038 uses the SC-88A (also known as SOT-353 or SC-70-5) package: a 5-pin, surface-mount outline with 2.00 mm × 1.25 mm body size, 0.95 mm height, and 0.65 mm lead pitch. Its compact footprint supports high-density PCB layouts in portable and automotive electronics.
What is the maximum operating temperature range for the M74VHC1GT02DFT1G-L22038?
The M74VHC1GT02DFT1G-L22038 is rated for operation from −55 °C to +125 °C. This extended industrial temperature range is validated per AEC-Q100 stress testing, making it suitable for under-hood automotive applications, industrial motor drives, and outdoor infrastructure equipment where ambient thermal extremes are expected.
How does the M74VHC1GT02DFT1G-L22038 differ from the MC74VHC1G02DFT1G variant?
The M74VHC1GT02DFT1G-L22038 uses TTL-level input thresholds (VIH = 1.4 V min at 3.0 V), whereas the MC74VHC1G02DFT1G uses CMOS-level thresholds (VIH = 2.1 V min at 3.0 V). This makes the M74VHC1GT02DFT1G-L22038 compatible with legacy 5 V TTL outputs without level shifters, while the MC74VHC1G02DFT1G is optimized for pure 3 V CMOS environments.
