Product details
Overview
MC74VHC1GT08DFT1G 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, over-voltage tolerant inputs/outputs up to 5.5 V, and IOFF partial power-down protection - used in level-shifting logic interfaces between 3 V and 5 V subsystems.
For engineers reviewing the MC74VHC1GT08DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include input threshold compatibility (TTL vs CMOS), supply voltage range, propagation delay under load, over-voltage tolerance, and SC-88A package footprint constraints.
Technical Context
The MC74VHC1GT08DFT1G implements a standard AND logic function using advanced VHC CMOS technology with TTL-compatible input thresholds (VIH = 1.0 V min at 2.0 V VCC; VIL = 0.28 V max). Its input structure tolerates voltages up to 5.5 V independent of VCC, enabling safe interfacing between mixed-supply domains.
It features IOFF circuitry that disables output leakage when VCC = 0 V, preventing back-powering of powered-down rails. Output drive capability is ±8 mA at 3.0 V, supporting direct connection to standard CMOS/TTL loads without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply systems and battery-powered 3.3 V designs with 5 V tolerance margin. |
| tPD (typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal gating in timing-critical control paths. |
| Input Thresholds | TTL-level: VIH = 1.0 V (min at 2.0 V), VIL = 0.28 V (max at 2.0 V) - ensures reliable recognition of legacy 5 V TTL outputs at lower VCC. |
| Over-Voltage Tolerance | Inputs/outputs withstand up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interconnects. |
| IOFF Protection | Active when VCC = 0 V - prevents current backflow into unpowered sections during hot-swap or partial power-down sequences. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74-series inputs or small capacitive loads without fanout limitation. |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
MC74VHC1GT08DFT1G is packaged in SC-88A (Case 419A), a 5-pin, 1.25 mm × 2.0 mm surface-mount package with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B input | Second logic input; accepts TTL- or CMOS-level signals up to 5.5 V independent of VCC. |
| 2 | A input | Primary logic input; electrically identical to Pin 1, fully over-voltage tolerant. |
| 3 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance for noise immunity. |
| 4 | Y output | AND result (A • B); actively driven high/low with ±8 mA capability at 3.0 V. |
| 5 | VCC | Positive supply rail; powers internal logic and defines output voltage levels and input thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Enables direct interface with legacy 5 V TTL outputs while operating from 3.3 V or 2.5 V supplies. |
| 5.5 V over-voltage tolerant I/O | Eliminates external protection components when connecting to higher-voltage buses or sensors. |
| IOFF partial power-down mode | Prevents destructive back-current flow when VCC is off but inputs/outputs remain active - critical for hot-plug systems. |
| −55 °C to +125 °C operation | Validated for automotive AEC-Q100 Grade 1 applications and harsh industrial environments. |
| SC-88A ultra-small footprint | 1.25 mm × 2.0 mm body size saves PCB area in space-constrained modules like sensor nodes and portable electronics. |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |
|---|---|
Use Scenario: Combining door lock status and ignition signal to enable window motor power only when vehicle is running and doors are unlocked. IC Role / Device Role / Timing Role: Single AND gate performing real-time safety interlock logic with sub-10 ns response. Use Value: Eliminates discrete transistor logic; leverages IOFF to isolate gate during ECU sleep mode without external isolation switches. |
Use Scenario: Validating presence of both 24 V field sensor signal and local enable command before activating solenoid driver. IC Role / Device Role / Timing Role: Level-translating AND gate converting 24 V opto-isolated input (via resistor divider) and 3.3 V microcontroller signal into 3.3 V output. Use Value: Over-voltage tolerant inputs accept divided 24 V directly; TTL thresholds ensure reliable detection despite divider tolerance drift. |

Use Scenario: Enabling USB-C VCONN power only after successful CC line negotiation and system ready flag assertion. IC Role / Device Role / Timing Role: Synchronous logic gate coordinating two asynchronous control signals with nanosecond timing integrity. Use Value: 3.5 ns tPD ensures minimal delay in safety-critical power sequencing; SC-88A footprint fits tight layout near USB-C connector. |
Use Scenario: Gating accelerometer interrupt signal with processor wake-enable flag to reduce false wake events in low-power sleep mode. IC Role / Device Role / Timing Role: Low-leakage AND gate suppressing interrupts until host MCU is fully operational. Use Value: IOFF blocks leakage path when MCU VCC is off; <1 µA ICC at 5.5 V minimizes standby current in battery-operated devices. |
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-level inputs (VIH = 1.7 V min at 3.3 V), slightly slower tPD (4.5 ns typ at 3.3 V), same SC-70-5 package. | Requires ≥3.0 V supply for full TTL-output compatibility; less suitable for 2.5 V or mixed 5 V input systems. | Select when system uses only CMOS logic families and operates strictly at 3.3 V. |
| NC7SZ08P5X | TTL-level inputs like MC74VHC1GT08DFT1G, but rated only to +85 °C ambient and lacks AEC-Q100 qualification. | Not approved for automotive under-hood use; limited thermal margin in enclosed industrial enclosures. | Select for cost-sensitive consumer or commercial applications where extended temperature range is not required. |
Compared with SN74LVC1G08DBVR and NC7SZ08P5X, MC74VHC1GT08DFT1G uniquely combines automotive-grade temperature range (−55 °C to +125 °C), AEC-Q100 qualification, TTL input compatibility down to 2.0 V, and 5.5 V over-voltage tolerance - making it the only option qualified for safety-critical automotive body electronics with legacy interface requirements.

FAQ
What logic family and input threshold type does MC74VHC1GT08DFT1G implement?
MC74VHC1GT08DFT1G implements a single 2-input AND gate in the VHC (Very High Speed CMOS) logic family with TTL-level input thresholds - specifically VIH(min) = 1.0 V at VCC = 2.0 V and VIL(max) = 0.28 V at VCC = 2.0 V. This allows reliable recognition of standard 5 V TTL outputs even when operating from a 2.5 V or 3.3 V supply, distinguishing it from CMOS-threshold variants like MC74VHC1G08.
Does MC74VHC1GT08DFT1G support level shifting between 5 V and 3.3 V domains?
Yes, MC74VHC1GT08DFT1G supports bidirectional level shifting: its inputs tolerate up to 5.5 V regardless of VCC, allowing direct connection to 5 V TTL outputs while powered from 3.3 V; its outputs swing rail-to-rail (0 V to VCC), producing clean 3.3 V logic levels. No external resistors or translators are needed, provided VCC is set to the desired output voltage domain.
Is MC74VHC1GT08DFT1G qualified for automotive applications?
Yes, MC74VHC1GT08DFT1G is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C junction) and PPAP capable. The "−Q" suffix in its ordering code (MC74VHC1GT08DFT1G−Q*) explicitly denotes compliance with automotive-specific site and change control requirements, making it suitable for body electronics, lighting control, and infotainment subsystems.
What package type and dimensions does MC74VHC1GT08DFT1G use?
MC74VHC1GT08DFT1G uses the SC-88A package (JEDEC MO-178, Case 419A): a 5-pin, surface-mount plastic package measuring 1.25 mm × 2.0 mm with 0.65 mm lead pitch. It features a single exposed pad variant and is RoHS-compliant, Pb-free, and halogen-free.
How does the IOFF feature of MC74VHC1GT08DFT1G improve system reliability?
The IOFF (power-off protection) feature in MC74VHC1GT08DFT1G disables output drivers when VCC = 0 V, limiting output leakage current to ≤10 µA. This prevents back-driving of unpowered rails during hot insertion, partial power-down, or battery backup scenarios - protecting downstream ICs and avoiding latch-up or data corruption in complex multi-rail systems.
