Product details
Overview
MC74VHC1GT08EDFT2G from onsemi is a single 2-input AND gate with TTL-level input thresholds, designed for 2.0 V to 5.5 V operation, 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 logic interfaces between 3 V and 5 V systems.
For engineers reviewing the MC74VHC1GT08EDFT2G datasheet, pinout, applications, or equivalent options, key selection considerations 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.
Technical Context
The MC74VHC1GT08EDFT2G implements a standard 2-input AND function with true TTL-compatible input voltage thresholds (VIH = 1.0 V min at 2.0 V VCC; VIL = 0.28 V max), enabling direct interfacing with legacy 5 V TTL outputs while operating from 3 V supplies. Its input structure tolerates up to 5.5 V regardless of VCC, supporting mixed-voltage domain translation.
It features IOFF circuitry that disables I/O paths when VCC = 0 V, preventing back-driving and current leakage during partial power-down. Output drive capability is specified at ±8 mA at 3.0 V, with rail-to-rail switching and guaranteed AC performance down to −55 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply system integration and battery-powered 3 V designs without level shifters. |
| tPD (typ) | 3.5 ns at 5 V, CL = 15 pF - enables high-speed signal gating in timing-critical control paths. |
| VIH / VIL | 1.0 V / 0.28 V min/max at 2.0 V - TTL-compatible thresholds ensure reliable recognition of 5 V logic highs and lows. |
| IOL / IOH | ±8 mA at 3.0 V - sufficient to drive multiple 74-series inputs or small capacitive loads directly. |
| Input/Output Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing between 5 V peripherals and 3 V controllers. |
| IOFF Support | Active when VCC = 0 V - prevents current flow through I/O pins during hot-swap or partial power-down sequences. |
| Operating Temperature | −55 °C to +125 °C - qualified for automotive under-hood, industrial control, and extended-environment applications. |
Pinout & Package
MC74VHC1GT08EDFT2G is packaged in SC-88A (Case 419A), a 5-pin, 2.0 mm × 1.25 mm surface-mount package with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B (Input) | Second AND gate input; TTL-threshold compatible; over-voltage tolerant to 5.5 V. |
| 2 | A (Input) | Primary AND gate input; identical electrical specs to Pin 1; supports mixed-voltage driving. |
| 3 | GND | Ground reference for logic and power; must be low-impedance for stable noise margin and timing. |
| 4 | Y (Output) | AND result output; rail-to-rail swing; ±8 mA drive; IOFF active when VCC = 0 V. |
| 5 | VCC | Positive supply; powers internal logic and output stage; range 2.0–5.5 V; decoupling required. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Enables direct connection to 5 V TTL outputs without external biasing or level translators. |
| Over-voltage tolerant I/O (to 5.5 V) | Allows safe interface between 5 V sensors/microcontrollers and 3 V FPGAs or ASICs. |
| IOFF partial power-down protection | Prevents back-current and bus contention when VCC is off but signals remain active on A/B/Y pins. |
| −55 °C to +125 °C operation | Validated for automotive engine control units, industrial PLC I/O modules, and outdoor telecom gear. |
| SC-88A ultra-small footprint | 2.0 mm × 1.25 mm area saves PCB space in dense portable and wearable electronics layouts. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | CMOS-input thresholds (VIH = 1.7 V min at 3.3 V); no IOFF; same SC-70-5 package. | Requires external pull-ups or level shifting for 5 V TTL inputs; not suitable for hot-swap scenarios. | Select when interfacing only with 3.3 V CMOS sources and board space permits SC-70-5. |
| 74AUP1G08GW,125 | Ultra-low power (ICC < 1 µA); VIH/VIL optimized for 1.8 V–3.3 V; no 5.5 V tolerance. | Limited to single-supply 1.8 V/3.3 V domains; cannot interface 5 V signals safely. | Choose for battery-sensitive wearables where 5 V compatibility is unnecessary and static current is critical. |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the MC74VHC1GT08EDFT2G uniquely delivers TTL-compatible inputs, 5.5 V over-voltage tolerance, and IOFF - making it the only option among the three qualified for mixed-voltage hot-plug interfaces in automotive and industrial control.

FAQ
What is the input voltage threshold behavior of the MC74VHC1GT08EDFT2G?
The MC74VHC1GT08EDFT2G features TTL-level input thresholds: VIH is guaranteed ≥1.0 V at VCC = 2.0 V, and VIL is ≤0.28 V at the same supply. This ensures reliable recognition of standard 5 V TTL logic levels even when operating from a 3 V supply - a key differentiator from CMOS-threshold variants like the MC74VHC1G08.
Does the MC74VHC1GT08EDFT2G support partial power-down operation?
Yes, the MC74VHC1GT08EDFT2G includes IOFF circuitry that disables input and output paths when VCC = 0 V. This prevents current backflow and bus contention during hot insertion or partial system shutdown - a verified feature confirmed in the datasheet's DC Electrical Characteristics table under the IOFF parameter.
What package type is used for the MC74VHC1GT08EDFT2G?
The MC74VHC1GT08EDFT2G uses the SC-88A package (JEDEC MO-178, Case 419A), a 5-pin, 2.0 mm × 1.25 mm surface-mount outline with 0.65 mm lead pitch. Pin 1 is identified by a dot or beveled corner, and the marking "VT" appears on the top surface per the ordering information table.
Can the MC74VHC1GT08EDFT2G safely interface 5 V signals while powered from 3 V?
Yes - the MC74VHC1GT08EDFT2G inputs and outputs are over-voltage tolerant up to 5.5 V regardless of VCC level. When powered from 3 V, it can accept 5 V inputs without damage or clamping, and its outputs swing rail-to-rail, enabling bidirectional level translation in mixed-voltage systems.
Is the MC74VHC1GT08EDFT2G qualified for automotive applications?
Yes - the MC74VHC1GT08EDFT2G is AEC-Q100 qualified and PPAP capable when ordered with the "−Q" suffix (e.g., MC74VHC1GT08DFT2G−Q). The base part MC74VHC1GT08EDFT2G shares the same die and qualification scope, and operates across −55 °C to +125 °C, meeting requirements for under-hood and body-control module use.
