Product details
Overview
MC74VHC1GT08DF2G from onsemi is a single 2-input TTL-level AND gate in SC-88A (SOT-353) package, operating from 2.0 V to 5.5 V, with 3.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and input/output over-voltage tolerance up to 5.5 V - used for level-shifting logic interfacing between 3 V and 5 V subsystems in portable instrumentation.
For engineers reviewing the MC74VHC1GT08DF2G datasheet, pinout, applications, or equivalent options, key selection considerations include TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 5.5 V), IOFF partial power-down support, 5-pin SC-88A footprint compatibility, and AEC-Q100 qualification for automotive signal conditioning.
Technical Context
The MC74VHC1GT08DF2G implements a standard 2-input AND function with TTL-level input thresholds (VIH = 1.0 V min at 2.0 V VCC; VIL = 0.28 V max), enabling direct interface with legacy 5 V TTL outputs while powered from 3.3 V supplies. Its CMOS output stage delivers rail-to-rail switching with 8 mA sink/source capability at 3.0 V.
Input and output structures tolerate voltages up to 5.5 V independent of VCC, supporting mixed-voltage domain bridging. The IOFF feature disables I/O leakage when VCC = 0 V, preventing back-powering in partial power-down systems such as battery-backed sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply systems and brown-out tolerant operation across industrial and automotive voltage rails. |
| tPD (typ) | 3.5 ns at VCC = 5.5 V, CL = 15 pF - enables high-speed combinational logic in timing-critical control paths. |
| VIH / VIL | 2.0 V / 0.8 V at VCC = 5.5 V - TTL-compatible thresholds allow direct connection to 5 V logic without level shifters. |
| IOUT | ±8 mA at VCC = 3.0 V - sufficient drive strength to fan out to multiple CMOS inputs or light LEDs directly. |
| Over-Voltage Tolerance | Inputs/outputs rated to 5.5 V regardless of VCC - eliminates need for external clamping diodes in 3 V–5 V interface circuits. |
| IOFF Support | Active when VCC = 0 V - prevents current backflow and data corruption during hot-swap or battery-swapping events. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial ambient environments. |
Pinout & Package
MC74VHC1GT08DF2G uses the SC-88A (SOT-353) 5-pin package (Case 419A), measuring 2.1 mm × 1.25 mm × 0.95 mm, with gull-wing leads and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B input | Second logic input; accepts TTL- or CMOS-level signals up to 5.5 V regardless of VCC. |
| 2 | A input | Primary logic input; identical electrical characteristics to Pin 1; enables standard AND truth table implementation. |
| 3 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance for stable noise margin and timing. |
| 4 | Y output | CMOS push-pull output; drives high/low actively; supports 8 mA sink/source at 3.0 V; over-voltage tolerant. |
| 5 | VCC | Positive supply; powers internal logic and output stage; IOFF activates automatically if pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Enables direct interface with legacy 5 V TTL outputs without external biasing or level translation. |
| 5.5 V over-voltage tolerant I/O | Allows safe operation when interfacing 3 V logic to 5 V buses - no external protection components required. |
| IOFF partial power-down | Prevents back-driving and latch-up during system sleep modes where VCC is removed but I/O lines remain active. |
| SC-88A ultra-small footprint | 2.1 mm × 1.25 mm area saves PCB space in space-constrained applications like wearables and sensor modules. |
| AEC-Q100 qualified (-Q variant available) | Validated for automotive use including temperature cycling, ESD, and reliability stress testing per Grade 1 requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | CMOS-level inputs (VIH = 2.0 V min at 3.3 V); slightly higher ICC (max 10 µA vs. 1 µA at 25 °C). | Best suited for pure 3.3 V systems; lacks native 5 V-tolerant inputs - requires external level shifting for 5 V interface. | Select when operating exclusively in 3.3 V domains and lowest static current is critical; avoid for mixed-voltage interfacing. |
| 74AUP1G08GW,125 | Lower VCC range (0.8 V–3.6 V); 3.7 ns tPD at 3.3 V; IOFF supported; smaller XSON-6 package (1.2 × 1.0 mm). | Targeted for ultra-low-power, single-supply battery applications; not rated for 5 V operation or 5.5 V over-voltage tolerance. | Choose for sub-1 V logic integration or extreme space constraints; unsuitable for automotive or 5 V legacy interface roles. |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the MC74VHC1GT08DF2G uniquely combines TTL input compatibility, 5.5 V over-voltage tolerance, and AEC-Q100 readiness - making it the only option among the three qualified for direct 3 V/5 V bridging in automotive and industrial control.

FAQ
What logic family and input threshold type does MC74VHC1GT08DF2G implement?
The MC74VHC1GT08DF2G is a VHC-series single 2-input AND gate with TTL-level input thresholds - VIH = 2.0 V (min) and VIL = 0.8 V (max) at VCC = 5.5 V. This distinguishes it from the CMOS-threshold MC74VHC1G08 variant and enables direct compatibility with legacy 5 V TTL outputs without external biasing networks. The MC74VHC1GT08DF2G maintains full functionality across its 2.0 V–5.5 V supply range.
Does MC74VHC1GT08DF2G support level-shifting between 3 V and 5 V systems?
Yes, the MC74VHC1GT08DF2G supports bidirectional level-shifting: its inputs and outputs tolerate up to 5.5 V regardless of VCC, allowing safe connection to 5 V signal lines while powered from 3.3 V or 2.5 V supplies. This eliminates external level translators in mixed-voltage designs - a key advantage confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official onsemi datasheet for MC74VHC1GT08DF2G.
What package type and pin count does MC74VHC1GT08DF2G use?
The MC74VHC1GT08DF2G uses the SC-88A (also known as SOT-353) surface-mount package with 5 gull-wing leads. Its dimensions are 2.1 mm × 1.25 mm × 0.95 mm, and it follows JEDEC MO-178AB case outline 419A. Pin 1 is marked by a dot or beveled edge, and the pinout is standardized as B–A–GND–Y–VCC (top view). This matches the DF2G suffix designation in onsemi's ordering information.
Is MC74VHC1GT08DF2G suitable for automotive applications?
Yes - while the base MC74VHC1GT08DF2G is industrial-grade, the −Q qualified variant (e.g., MC74VHC1GT08DF2G−Q) is AEC-Q100 Grade 1 certified (−40 °C to +125 °C) and PPAP-capable. The underlying die and design are identical; only test screening and traceability differ. Customers requiring automotive qualification should specify the −Q suffix, but the MC74VHC1GT08DF2G shares the same electrical specs, thermal performance, and reliability fundamentals.
What is the propagation delay and drive strength of MC74VHC1GT08DF2G at 3.3 V?
At VCC = 3.3 V and CL = 15 pF, the MC74VHC1GT08DF2G exhibits a typical propagation delay (tPLH/tPHL) of 4.1 ns and maximum of 10.5 ns over temperature. It delivers ±8 mA output drive (IOL/IOH) at 3.0 V, sufficient to drive multiple 74LVC inputs or small indicator LEDs. These values are verified in the AC and DC Electrical Characteristics sections of the official onsemi datasheet for MC74VHC1GT08DF2G.
