Product details
Overview
MC74VHC1G08DTT1G from onsemi is a single 2-input AND gate in SC-74A (SOT-23-5) package, operating from 2.0 V to 5.5 V, with CMOS-level input thresholds, 3.5 ns typical propagation delay at 5 V, and over-voltage tolerant inputs/outputs up to 5.5 V - enabling robust 3 V/5 V mixed-supply interfacing in portable logic control circuits.
For engineers reviewing the MC74VHC1G08DTT1G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package mapping, real-world interface use cases, and two validated alternative parts for voltage-level translation and low-power combinational logic design.
Technical Context
The MC74VHC1G08DTT1G implements a standard positive-logic AND function with rail-to-rail output swing and input thresholds compliant with CMOS levels (VIH = 70% VCC, VIL = 30% VCC). Its IOFF circuitry enables partial power-down protection when VCC = 0 V, preventing back-driving and current leakage between powered and unpowered subsystems.
Input and output structures tolerate voltages up to 5.5 V independent of VCC, supporting safe interfacing between 5 V legacy peripherals and 3 V microcontrollers. The device drives ±8 mA at 3.0 V and exhibits 4.0 pF typical input capacitance, minimizing loading on upstream drivers in high-speed digital signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V logic domains without level shifters. |
| tPD (Propagation Delay) | 3.5 ns typ @ 5 V, CL = 15 pF - enables reliable operation in sub-100 MHz clocked logic and fast enable/disable paths. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - allows safe connection to 5 V signals even when VCC = 3.3 V or 2.5 V, eliminating external clamping diodes. |
| IOFF Leakage Current | ≤10 µA @ VCC = 0 V - prevents bus contention and power loss during hot-swap or partial system shutdown. |
| Output Drive Strength | ±8 mA @ 3.0 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering. |
| Operating Temperature | −55 °C to +125 °C - qualified for industrial and automotive under-hood applications per AEC-Q100 (−Q suffix variants). |
| ESD Rating | HBM: 2000 V - provides robust handling margin during PCB assembly and field service without special ESD precautions. |
Pinout & Package
MC74VHC1G08DTT1G is packaged in SC-74A (SOT-23-5), a 3.0 mm × 1.5 mm × 0.95 mm surface-mount package with gull-wing leads and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second logic input; accepts CMOS-level signals up to 5.5 V regardless of VCC. |
| 2 | Input A | Primary logic input; electrically identical to Pin 1, fully interchangeable in layout. |
| 3 | GND | Ground reference for all internal circuitry and I/O; must be connected before VCC for safe power sequencing. |
| 4 | Output Y | AND result (A • B); rail-to-rail swing, over-voltage tolerant, supports tri-state behavior only in MC74VHC1GT08 variants. |
| 5 | VCC | Positive supply; powers internal logic and output stage; IOFF active when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (2.0–5.5 V) | Eliminates need for separate voltage regulators in multi-rail systems; simplifies BOM across 2.5 V, 3.3 V, and 5 V designs. |
| Over-voltage tolerant I/O | Enables direct 5 V-to-3 V interfacing without external resistors or translators - reduces component count and board space. |
| IOFF partial power-down | Blocks current flow through inputs/outputs when VCC is off, protecting downstream devices during firmware updates or sleep mode. |
| Low dynamic power (CPD = 8.0 pF) | Minimizes switching current in battery-powered systems; ICC(OPR) = 8.0 pF × VCC² × f + ICC(quiescent). |
| AEC-Q100 qualified variants | MC74VHC1G08DBVT1G−Q offers automotive-grade reliability, PPAP support, and controlled change management for Tier 1 suppliers. |
Applications

Use Scenario: Gating environmental sensor interrupts to avoid spurious wake-ups caused by noise on shared interrupt lines. IC Role / Device Role: Debounce and validation gate combining motion-detection and ambient-light signals before triggering MCU interrupt. Use Value: Reduces false wake events by >90%; low 3.5 ns tPD preserves real-time response for time-sensitive edge analytics. |
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 | TTL-compatible VIH/VIL; 3.3 V only rated (1.65–5.5 V), no 2.0 V operation; lower ICC but no IOFF. | Suitable for pure 3.3 V systems with tight power budgets; not recommended for 2.0 V or mixed-voltage hot-swap scenarios. | Select when cost and footprint are critical and full 2.0–5.5 V operation is unnecessary. |
| 74AUP1G08GW,125 | Ultra-low power (ICC < 1 µA); 1.1–3.6 V only; 6.0 ns tPD @ 3.3 V; no over-voltage tolerance. | Ideal for always-on battery sensors; cannot interface 5 V signals or survive VCC = 0 V with live inputs. | Choose for energy-constrained IoT endpoints where voltage domain isolation is guaranteed. |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the MC74VHC1G08DTT1G uniquely combines 2.0 V minimum operation, 5.5 V over-voltage tolerance, and IOFF - making it the only option among the three that safely bridges 2.5 V/3.3 V logic to 5 V peripherals while supporting partial power-down.

FAQ
What is the maximum input voltage rating for MC74VHC1G08DTT1G?
The MC74VHC1G08DTT1G supports DC input voltages from −0.5 V to +5.5 V, independent of VCC. This over-voltage tolerance allows safe connection to 5 V signals even when operating at 2.0 V or 3.3 V, eliminating the need for external clamping components in mixed-supply designs.
Does MC74VHC1G08DTT1G support partial power-down functionality?
Yes, MC74VHC1G08DTT1G features IOFF circuitry that disables input and output paths when VCC = 0 V, limiting leakage current to ≤10 µA. This prevents back-driving and bus contention in systems where subsystems power up/down asynchronously - a key requirement in portable and automotive applications.
What package type is used for MC74VHC1G08DTT1G?
MC74VHC1G08DTT1G is supplied in the SC-74A (SOT-23-5) package: a 3.0 mm × 1.5 mm × 0.95 mm surface-mount outline with five gull-wing leads, moisture sensitivity level 1, and RoHS-compliant Pb-free construction - optimized for high-density PCB layouts and automated assembly.
How does MC74VHC1G08DTT1G differ from MC74VHC1GT08 variants?
MC74VHC1G08DTT1G uses CMOS-level input thresholds (VIH ≈ 70% VCC), while MC74VHC1GT08 uses TTL-level thresholds (VIH ≈ 2.0 V fixed). Both share identical output drive, timing, and over-voltage specs, but MC74VHC1G08DTT1G is preferred for modern low-voltage CMOS systems, whereas MC74VHC1GT08 suits legacy TTL interfacing.
Is MC74VHC1G08DTT1G qualified for automotive applications?
The base MC74VHC1G08DTT1G is not automotive-qualified, but its pin-compatible variant MC74VHC1G08DBVT1G−Q is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C), PPAP-capable, and manufactured under automotive-specific process controls - required for body electronics, lighting, and infotainment modules.
