Product details
Overview
74VHCT00AMX from onsemi is a quad 2-input NAND gate IC in TSSOP-14 WB package, operating at 4.5–5.5 V supply with 5.0 ns typical propagation delay, 2.0 V VIH and 0.8 V VIL input thresholds, and designed for 3 V/5 V mixed-voltage interface applications in industrial control logic.
For engineers reviewing the 74VHCT00AMX datasheet, pinout, applications, or equivalent options, key selection factors include its TTL-compatible speed, CMOS power efficiency, input/output overvoltage tolerance up to 5.5 V, and guaranteed operation across −40°C to +85°C.
Technical Context
The 74VHCT00AMX implements four independent NAND gates using silicon-gate CMOS technology with three-stage buffered output architecture, delivering high noise immunity (VIH = 2.0 V, VIL = 0.8 V) and stable switching under load. Its internal protection circuits allow 0–5.5 V input voltage regardless of VCC state.
It supports dual-supply system interfacing (e.g., battery backup), features power-down protection on all I/O pins, and maintains functional integrity when VCC = 0 V - enabling hot-swap and level-shifting use cases without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems while tolerating supply variation. |
| tPD (Typ.) | 5.0 ns at VCC = 5.0 V, CL = 15 pF - enables high-speed combinational logic in timing-critical paths. |
| VIH / VIL | 2.0 V / 0.8 V - provides robust noise margin and reliable recognition of TTL-level inputs. |
| IOH / IOL | −8 mA / +8 mA - drives standard TTL loads directly without buffering. |
| ICC (Max) | 2.0 µA at TA = 25°C - ultra-low static power ideal for battery-backed or always-on logic. |
| Input Voltage Range | −0.5 V to +6.5 V - allows safe interfacing with higher-voltage signals or mismatched supplies. |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded control environments. |
Pinout & Package
TSSOP-14 WB (Case 948G), 4.9 mm × 4.4 mm body, 0.65 mm pitch, Pb-free, RoHS-compliant surface-mount package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | A0/B0, A1/B1, A2/B2, A3/B3 | Four independent NAND input pairs - each pair feeds one gate; unused inputs must be tied HIGH/LOW. |
| 3, 6, 10, 13 | O0, O1, O2, O3 | Four complementary NAND outputs - rail-to-rail CMOS swing, capable of driving 10 LSTTL loads. |
| 7 | GND | Ground reference for all logic and power domains - required for proper noise immunity and DC biasing. |
| 14 | VCC | Positive supply pin - powers all four gates; decoupling capacitor recommended within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS NAND | 5.0 ns typical propagation delay matches TTL performance while consuming <2 µA static current. |
| Overvoltage-tolerant I/O | Inputs accept 0–5.5 V and outputs tolerate 0–5.5 V even with VCC = 0 V - eliminates need for external level shifters. |
| Power-down protection | All inputs and outputs remain protected during power sequencing or brown-out - prevents latch-up or damage. |
| Pb-free & RoHS compliance | Meets global environmental standards without compromising electrical or thermal performance in reflow assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT00D,118 | Same logic function, SO-14 package; tPD = 5.5 ns (max), VIH/VIL identical; no overvoltage tolerance beyond VCC + 0.5 V. | Requires strict 4.5–5.5 V supply alignment; unsuitable for mixed-voltage or hot-swap scenarios. | Select when board space permits SOIC and system voltage rails are tightly regulated. |
| SN74LVC00APWR | 3.3 V only (1.65–3.6 V); tPD = 3.9 ns (typ); lower drive (±24 mA); no 5 V tolerant inputs. | Designed for low-voltage digital systems; incompatible with 5 V signal domains without translation. | Choose for new 3.3 V designs prioritizing speed and density over 5 V interoperability. |
Compared with 74HCT00D,118 and SN74LVC00APWR, the 74VHCT00AMX uniquely combines 5 V operation, 5.5 V I/O tolerance, and sub-6 ns delay - making it the only option for robust 5 V mixed-signal interfacing where supply sequencing or voltage mismatch is possible.

FAQ
What is the maximum supply voltage rating for the 74VHCT00AMX?
The 74VHCT00AMX has an absolute maximum DC supply voltage (VCC) rating of −0.5 V to +6.5 V per the onsemi datasheet. However, for reliable operation, it must be powered within the recommended range of 4.5 V to 5.5 V. Exceeding 5.5 V may cause permanent damage despite the higher absolute rating.
Can the 74VHCT00AMX safely interface with 3.3 V microcontroller GPIOs?
Yes - the 74VHCT00AMX accepts 3.3 V logic-high inputs reliably because its VIH threshold is only 2.0 V at VCC = 4.5–5.5 V. A 3.3 V signal exceeds this minimum, ensuring correct HIGH recognition. Outputs swing rail-to-rail (0 V / ~5 V), so level-shifting is required if driving 3.3 V–only inputs.
Does the 74VHCT00AMX support tri-state operation?
No - the 74VHCT00AMX does not feature tri-state outputs. It is a standard quad 2-input NAND gate with push-pull CMOS outputs. The datasheet mentions "Tristate Mode" only in the context of maximum ratings for devices *with* tri-state capability - which does not apply to this part. All four outputs are always active.
Is the 74VHCT00AMX pin-compatible with the older 74HCT00 series?
Yes - the 74VHCT00AMX is explicitly stated in the datasheet to be pin- and function-compatible with the 74HCT00. This includes identical pin assignments (TSSOP-14 layout), truth table behavior, and logic function. No PCB changes are required when upgrading from 74HCT00 to 74VHCT00AMX.
What is the input leakage current specification for the 74VHCT00AMX at 85°C?
Per the onsemi datasheet, the maximum input leakage current (IIN) for the 74VHCT00AMX is ±1.0 µA over the full operating temperature range of −40°C to +85°C, measured at VIN = 5.5 V or GND and VCC = 5.5 V. This value ensures minimal loading on upstream drivers even at elevated temperatures.
