Product details
Overview
MC74VHC1GT00P5T5G from onsemi is a single 2-input NAND gate with TTL-level input thresholds, designed for 2.0 V to 5.5 V operation in SOT-953 (5-pin) package. It delivers 3.5 ns typical propagation delay at 5 V, supports 8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V - enabling robust 3 V/5 V mixed-supply interfacing in portable logic systems.
For engineers reviewing the MC74VHC1GT00P5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include TTL-compatible VIH/VIL thresholds (1.4 V/0.45 V at 3.0 V), IOFF partial power-down protection, and SOT-953 footprint compatibility with space-constrained PCB layouts.
Technical Context
The MC74VHC1GT00P5T5G implements standard CMOS NAND logic with TTL-level input voltage thresholds - VIH = 1.4 V (min) and VIL = 0.45 V (max) at VCC = 3.0 V - distinguishing it from the CMOS-threshold MC74VHC1G00 variant. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe level-shifting between 3 V and 5 V domains.
Output stages support active-drive capability (±8 mA at 3.0 V) and retain over-voltage tolerance even when VCC = 0 V. The device includes IOFF circuitry that disables I/O paths during power-down, preventing back-driving and signal contention in partial-power-down systems.
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 families without level shifters. |
| tPD (Typ) | 3.5 ns at 5 V - ensures fast timing closure in high-speed digital control paths and clocked logic chains. |
| VIH / VIL | 1.4 V / 0.45 V (min/max) at 3.0 V - guarantees reliable recognition of TTL-compatible input signals in mixed-voltage systems. |
| IOL / IOH | 8 mA sink/source at 3.0 V - drives multiple 74-series or modern logic inputs without external buffering. |
| Input/Output Voltage Tolerance | Up to 5.5 V regardless of VCC - eliminates risk of damage during hot insertion, battery backup, or supply sequencing mismatches. |
| IOFF Support | Active when VCC = 0 V - prevents current leakage and bus contention in powered-down subsystems. |
| Operating Temperature | −55 °C to +125 °C - qualified for industrial and extended-temperature embedded applications. |
Pinout & Package
SOT-953 (5-pin, 1.00 mm × 0.80 mm × 0.37 mm, 0.35 mm pitch) surface-mount package with exposed pad option; optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A (Input) | First NAND input; accepts TTL- or CMOS-level signals up to 5.5 V regardless of VCC. |
| 2 | GND | Ground reference for logic and power; required for proper IOFF activation and noise immunity. |
| 3 | B (Input) | Second NAND input; electrically identical to Pin 1 with same over-voltage tolerance. |
| 4 | Y (Output) | Inverted AND output; drives loads up to 8 mA while maintaining VOL ≤ 0.44 V at 3.0 V. |
| 5 | VCC | Positive supply; powers internal logic and enables output drive strength scaling with voltage. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Ensures interoperability with legacy 74LS/74F outputs and microcontroller GPIOs lacking CMOS rail-to-rail swing. |
| Over-voltage tolerant I/O (5.5 V) | Eliminates need for external clamping diodes when interfacing 5 V sensors or peripherals to 3.3 V controllers. |
| IOFF partial power-down protection | Prevents back-current flow and bus conflicts when VCC is off but system signals remain active - critical for modular hot-swap designs. |
| Low propagation delay (3.5 ns typ @ 5 V) | Supports >100 MHz toggle rates in re-timing or synchronization circuits without added latency. |
| Pb-Free, RoHS-compliant packaging | Meets global environmental compliance requirements for industrial, automotive, and consumer electronics manufacturing. |
Applications

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 |
|---|---|---|---|
| MC74VHC1G00P5T5G | CMOS-level input thresholds (VIH = 2.1 V min at 3.0 V); otherwise identical AC/DC specs and pinout. | Requires full CMOS-swing inputs; unsuitable for direct connection to 5 V TTL outputs or open-collector drivers. | Select when interfacing exclusively with modern 3.3 V logic families (e.g., ARM GPIO, FPGA I/O) with rail-to-rail output swing. |
| SN74LVC1G00DBVR | Wider VCC range (1.65–5.5 V); lower tPD (3.1 ns typ @ 3.3 V); no IOFF support; different pinout (Pin 1 = A, Pin 2 = GND, Pin 3 = B, Pin 4 = Y, Pin 5 = VCC). | Lacks power-down isolation; not suitable for partial-power-down architectures requiring back-drive prevention. | Choose for lowest propagation delay in always-on 3.3 V systems where IOFF is unnecessary and layout allows pinout adaptation. |
Compared with MC74VHC1GT00P5T5G, MC74VHC1G00P5T5G offers higher noise immunity with CMOS thresholds but sacrifices TTL compatibility, while SN74LVC1G00DBVR improves speed and supply flexibility at the cost of IOFF functionality and requires PCB redesign due to non-identical pin assignment.

FAQ
What is the input voltage threshold behavior of the MC74VHC1GT00P5T5G?
The MC74VHC1GT00P5T5G features TTL-level input thresholds: VIH is 1.4 V (min) and VIL is 0.45 V (max) at VCC = 3.0 V. This allows reliable recognition of standard TTL output levels (e.g., 74LS, 74F) without external level translation. These thresholds are confirmed in the DC Electrical Characteristics table for MC74VHC1GT00 on page 5 of the datasheet, and apply directly to the MC74VHC1GT00P5T5G variant.
Does the MC74VHC1GT00P5T5G support partial power-down operation?
Yes, the MC74VHC1GT00P5T5G includes IOFF circuitry that disables both input and output paths when VCC = 0 V. This prevents back-current flow and bus contention in systems where some sections remain powered while others are shut down. The feature is explicitly documented in the Features section and verified in the DC Electrical Characteristics table under IOFF parameter (1.0 µA max at 0 V).
What is the maximum propagation delay of the MC74VHC1GT00P5T5G across its operating range?
The MC74VHC1GT00P5T5G has a maximum propagation delay of 11.0 ns (tPLH/tPHL) at VCC = 3.0–3.6 V, CL = 15 pF, and TA = −55 °C to +125 °C. At 4.5–5.5 V and same conditions, max delay is 8.0 ns. These values are specified in the AC Electrical Characteristics table on page 5 and reflect worst-case performance under full temperature and voltage range.
Can the MC74VHC1GT00P5T5G safely interface a 5 V sensor output to a 3.3 V microcontroller input?
Yes - the MC74VHC1GT00P5T5G inputs tolerate up to 5.5 V regardless of VCC, so a 5 V sensor output can be directly connected to Pin 1 or Pin 3 without clamping or attenuation. Its TTL thresholds ensure correct logic interpretation, and the output swings rail-to-rail (0 V to VCC), making it compatible with 3.3 V MCU inputs. This capability is confirmed in the "Inputs/Outputs Over-Voltage Tolerant" feature and Maximum Ratings table.
Is the MC74VHC1GT00P5T5G pin-compatible with other SOT-953 logic gates?
No - the MC74VHC1GT00P5T5G uses a specific SOT-953 pinout (Pin 1 = A, Pin 2 = GND, Pin 3 = B, Pin 4 = Y, Pin 5 = VCC) that differs from common alternatives like SN74LVC1G00DBVR (Pin 1 = A, Pin 2 = GND, Pin 3 = B, Pin 4 = Y, Pin 5 = VCC - same order) but is not guaranteed to match all SOT-953 logic devices. Always verify pin assignment per datasheet; this exact mapping is shown in Figure 2 (SOT-953) on page 2 of the MC74VHC1G00/MC74VHC1GT00 datasheet.
