Product details
Overview
MC74VHC1GT00DT1G from onsemi is a single 2-input NAND gate with TTL-level input thresholds, designed for level-shifting and logic interfacing in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns propagation delay at 5 V (typ), supports ±8 mA output drive at 3.0 V, and is packaged in SC-74A (SOT-25) - enabling compact board integration in portable and industrial control applications.
For engineers reviewing the MC74VHC1GT00DT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its TTL-compatible VIH/VIL thresholds (1.4 V/0.45 V at 3.0 V), overvoltage-tolerant I/O up to 5.5 V, IOFF partial power-down support, and SC-74A package compatibility with high-density PCB layouts.
Technical Context
The MC74VHC1GT00DT1G implements a CMOS-based NAND gate with TTL-level input switching thresholds - distinct from the CMOS-threshold MC74VHC1G00 variant - enabling direct interface with legacy 5 V TTL logic while powered from 3.3 V supplies. Its input structure tolerates voltages up to 5.5 V independent of VCC, supporting robust 5 V-to-3 V signal translation.
It features IOFF circuitry that disables outputs when VCC = 0 V, preventing back-driving of powered rails during hot insertion or partial power-down. Output stages are rated for ±8 mA sink/source at 3.0 V and maintain rail-to-rail logic swing across the full 2.0–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables operation across 3.3 V and 5 V systems without level shifters. |
| tPD (Typ) | 3.5 ns at 5 V - ensures fast timing response in high-speed digital control paths. |
| VIH / VIL (3.0 V) | 1.4 V / 0.45 V - matches standard TTL input thresholds for seamless 5 V logic compatibility. |
| IOUT (3.0 V) | ±8 mA - sufficient to drive multiple 74-series inputs or small LED loads directly. |
| IOFF Support | Active when VCC = 0 V - prevents current leakage and bus contention during power sequencing. |
| Input Overvoltage | Tolerates up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-supply interfaces. |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood and industrial environments. |
Pinout & Package
MC74VHC1GT00DT1G is supplied in the SC-74A (SOT-25) 5-pin surface-mount package (Case 318BQ), measuring 3.00 × 1.50 × 0.95 mm with 0.95 mm pitch. This compact, lead-free, RoHS-compliant package supports automated placement and reflow soldering in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input A | First NAND input; TTL-compatible threshold (0.45 V low, 1.4 V high at 3.0 V). |
| 2 (GND) | Ground | Reference return path for all internal logic and I/O; must be low-impedance. |
| 3 (B) | Input B | Second NAND input; identical TTL threshold behavior as Pin 1. |
| 4 (Y) | Output Y | NAND result (Y = NOT(A AND B)); rail-to-rail CMOS output swing, ±8 mA capable. |
| 5 (VCC) | Supply Voltage | Positive supply rail (2.0–5.5 V); powers internal logic and enables IOFF protection when at 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Enables direct connection to legacy 5 V TTL outputs without external biasing or resistors. |
| Overvoltage-tolerant I/O (5.5 V) | Allows safe interfacing between 5 V microcontrollers and 3.3 V FPGAs without voltage translators. |
| IOFF partial power-down | Prevents back-current flow when VCC is off - critical for hot-pluggable modules and battery-backed systems. |
| Low propagation delay (3.5 ns @ 5 V) | Supports >100 MHz toggle rates in feedback loops and clock-domain synchronization circuits. |
| SC-74A package footprint | Matches industry-standard SOT-25 land pattern - simplifies layout reuse and reduces routing congestion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G00DBVT1G | CMOS-level input thresholds (VIH = 2.1 V at 3.0 V), otherwise identical AC/DC specs and SC-74A packaging. | Requires compatible CMOS drivers; unsuitable for direct 5 V TTL input interfacing. | Select when interfacing with 3.3 V CMOS logic; avoid when connecting to 5 V TTL sources. |
| SN74LVC1G00DBVR | Same SC-74A package; lower VCC min (1.65 V); VIH/VIL tighter (2.0/0.7 V at 3.3 V); no IOFF support. | Lacks power-down isolation; not suitable for hot-swap or partial-power-down systems. | Prefer for ultra-low-voltage battery operation; avoid where VCC may go to 0 V during system sleep. |
Compared with MC74VHC1GT00DT1G, the MC74VHC1G00DBVT1G offers CMOS-compatible thresholds but loses TTL interoperability, while SN74LVC1G00DBVR extends low-voltage operation but sacrifices IOFF protection - making MC74VHC1GT00DT1G uniquely suited for mixed-supply, hot-plug-capable designs.

FAQ
What is the input voltage threshold behavior of the MC74VHC1GT00DT1G?
The MC74VHC1GT00DT1G features TTL-level input thresholds: at VCC = 3.0 V, VIH is 1.4 V (min) and VIL is 0.45 V (max). This allows direct interfacing with standard 5 V TTL outputs without external biasing, distinguishing it from the CMOS-threshold MC74VHC1G00 series. These values are guaranteed across −55 °C to +125 °C.
Does the MC74VHC1GT00DT1G support partial power-down operation?
Yes, the MC74VHC1GT00DT1G includes IOFF circuitry that disables outputs when VCC = 0 V. This prevents back-current flow into powered downstream circuits during hot insertion or partial system shutdown - a critical feature for modular systems and battery-backed applications where MC74VHC1GT00DT1G is used as interface logic.
What package type is used for the MC74VHC1GT00DT1G?
The MC74VHC1GT00DT1G is packaged in SC-74A (also known as SOT-25), a 5-pin surface-mount package (Case 318BQ) with dimensions 3.00 × 1.50 × 0.95 mm and 0.95 mm lead pitch. It is Pb-free, halogen-free, and RoHS compliant - fully compatible with standard SOT-25 footprints and reflow profiles.
Can the MC74VHC1GT00DT1G safely interface 5 V signals while powered from 3.3 V?
Yes, the MC74VHC1GT00DT1G inputs tolerate up to 5.5 V regardless of VCC level. When powered from 3.3 V, it accepts 5 V logic inputs without damage or external clamping, and outputs a clean 3.3 V CMOS-level signal. This overvoltage capability is explicitly characterized and guaranteed in the datasheet for MC74VHC1GT00DT1G.
What is the typical propagation delay of the MC74VHC1GT00DT1G at 5 V supply?
The typical propagation delay (tPD) of the MC74VHC1GT00DT1G is 3.5 ns at VCC = 5 V, CL = 15 pF, and TA = 25 °C. This value is measured from either input (A or B) to output (Y) and reflects the device's high-speed performance in real-world 5 V logic systems - a key parameter confirmed in the AC Electrical Characteristics table for MC74VHC1GT00DT1G.
