Product details
Overview
MC74VHC1G00DTT1G from onsemi is a single 2-input NAND gate IC 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 typical propagation delay at 5 V, features over-voltage tolerant inputs/outputs up to 5.5 V, and supports partial power-down protection via IOFF. It is used in voltage translation between 3 V and 5 V digital subsystems in industrial control and portable electronics.
For engineers reviewing the MC74VHC1G00DTT1G datasheet, pinout, applications, or equivalent options, key selection criteria include input threshold compatibility (CMOS-level), IOFF support for hot-swap safety, 8 mA drive capability at 3.0 V, and SC-74A package suitability for space-constrained PCB layouts.
Technical Context
The MC74VHC1G00DTT1G implements a standard CMOS NAND logic function with rail-to-rail output swing and input thresholds defined as VIH ≥ 70% VCC and VIL ≤ 30% VCC. Its input structure withstands 5.5 V regardless of VCC, enabling robust 5 V → 3 V interface operation without external clamping.
It incorporates IOFF circuitry that disables I/O leakage when VCC = 0 V, preventing back-powering of powered-down rails. Output drive strength is specified at ±8 mA at 3.0 V, supporting TTL-compatible loads while maintaining low quiescent current (ICC ≤ 40 µA at 5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - Enables direct use across 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| tPD (typ) | 3.5 ns at 5 V - Supports high-speed signal conditioning in timing-critical paths such as clock enable gating. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows safe connection to 5 V signals even when VCC = 3.3 V or 2.5 V. |
| IOFF Leakage | <10 µA at VCC = 0 V - Prevents current backflow during partial power-down, critical for hot-plug and battery-backup systems. |
| Output Drive | ±8 mA at 3.0 V - Sufficient to drive multiple 74LVC inputs or one standard TTL load without buffering. |
| Operating Temp | −55 °C to +125 °C - Qualified for extended industrial and automotive under-hood applications. |
| ESD Rating | 2000 V HBM - Provides baseline ESD robustness for handling and assembly in non-classified environments. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A (Input) | First NAND input; CMOS-level threshold (VIH ≥ 1.4 V @ 2 V, ≥ 3.15 V @ 4.5 V); accepts 0–5.5 V regardless of VCC. |
| 2 | GND | Ground reference for logic and power; must be connected before VCC for proper IOFF activation. |
| 3 | B (Input) | Second NAND input; identical electrical characteristics to Pin 1; enables dual-input logic decision path. |
| 4 | Y (Output) | NAND output; rail-to-rail swing (VOH ≥ 1.9 V @ 2 V, VOL ≤ 0.1 V); over-voltage tolerant up to 5.5 V even at VCC = 0 V. |
| 5 | VCC | Positive supply; powers internal logic and defines input thresholds; IOFF active only when VCC = 0 V. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum input voltage the MC74VHC1G00DTT1G can tolerate?
The MC74VHC1G00DTT1G supports DC input voltages up to 5.5 V regardless of VCC level - a key feature enabling safe interfacing between 5 V and lower-voltage logic domains. This over-voltage tolerance is explicitly guaranteed in the Absolute Maximum Ratings table and applies to both input pins A and B, even when VCC is as low as 2.0 V or 0 V.
Does the MC74VHC1G00DTT1G support partial power-down operation?
Yes, the MC74VHC1G00DTT1G includes IOFF circuitry that actively limits input/output leakage to less than 10 µA when VCC = 0 V. This feature prevents back-driving of powered-down sections of a system, which is essential for hot-swap capability, battery backup circuits, and multi-rail power sequencing - all confirmed in the datasheet's Features and DC Electrical Characteristics sections.
What is the typical propagation delay of the MC74VHC1G00DTT1G at 3.3 V?
While the datasheet specifies 3.5 ns typical propagation delay at 5 V, it does not list a typ value at 3.3 V. However, AC Electrical Characteristics show tPLH/tPHL ≤ 9.5 ns (max) at VCC = 3.0–3.6 V with CL = 15 pF. Based on VHC family behavior and interpolation from published curves, typical delay at 3.3 V is approximately 5.0–5.5 ns - consistent with the MC74VHC1G00DTT1G's design target for high-speed operation across its full supply range.
Which package type does the MC74VHC1G00DTT1G use?
The MC74VHC1G00DTT1G uses the SC-74A package (Case 318BQ), a 5-pin surface-mount outline measuring 3.00 mm × 1.50 mm × 0.95 mm with 0.95 mm lead pitch. This is confirmed in the Ordering Information table on page 7 of the datasheet, where "MC74VHC1G00DBVT1G" - the SC-74A variant - shares the same base part number prefix and functional specifications as MC74VHC1G00DTT1G.
Is the MC74VHC1G00DTT1G suitable for automotive applications?
The base MC74VHC1G00DTT1G is not automotive-qualified, but onsemi offers automotive-grade versions in the same family - e.g., MC74VHC1G00DBVT1G-Q - which are AEC-Q100 qualified and PPAP capable. These share identical logic function, pinout, and electrical specs, differing only in traceability, screening, and qualification testing. For automotive use, specify the -Q suffix variant.
