Product details
Overview
74VHCT00AM 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 / 0.8 V VIL input thresholds, and ±8 mA output drive-used for level-shifting and logic interfacing between 3 V and 5 V systems.
For engineers reviewing the 74VHCT00AM datasheet, pinout, applications, or equivalent options, key selection criteria include TTL-compatible input thresholds, power-down protection on all I/O, low-noise output (VOLP ≤ 0.8 V), and guaranteed operation across −40°C to +85°C industrial temperature range.
Technical Context
The 74VHCT00AM implements four independent NAND gates using silicon-gate CMOS technology, achieving bipolar-Schottky TTL speed while retaining CMOS low power. Its three-stage internal structure includes buffered outputs for high noise immunity and stable switching.
Input protection circuits allow safe application of 0–5.5 V signals regardless of VCC state-including during power-down or battery-backup transitions-enabling robust interfacing between mismatched supply domains 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 digital rails and tolerance against supply droop. |
| tPD (Typ.) | 5.0 ns at CL = 15 pF - Enables use in high-speed control logic up to ~100 MHz toggle rate. |
| VIH / VIL | 2.0 V / 0.8 V - Matches TTL input thresholds, allowing direct connection to legacy 5 V TTL outputs. |
| IOL / IOH | ±8 mA - Sufficient to drive multiple 74-series inputs or small LED loads without buffering. |
| ICC (Max) | 2.0 µA at TA = 25°C - Ultra-low static current supports battery-backed or always-on subsystems. |
| VOLP (Max) | 0.8 V - Limits ground bounce and crosstalk in dense PCB layouts with simultaneous switching. |
| Operating Temp | −40°C to +85°C - Qualified for industrial-grade embedded control and automotive body electronics. |
Pinout & Package
TSSOP-14 WB (Case 948G), 4.9 mm × 4.4 mm × 1.2 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–A3/B3 Inputs | Four independent NAND gate inputs; each pair (e.g., A0/B0) feeds one gate; all support 0–5.5 V tolerant operation. |
| 3, 6, 10, 13 | O0–O3 Outputs | Push-pull CMOS outputs; actively driven HIGH/LOW; no inherent tri-state (not configurable). |
| 7 | GND | Ground reference for all logic and power paths; must be low-impedance connection to minimize noise coupling. |
| 14 | VCC | Positive supply rail; decoupling capacitor (0.1 µF) required within 5 mm for stable AC performance. |
Key Features
| Feature | Design Value |
|---|---|
| Pin & function compatible with 74HCT00 | Drop-in replacement for existing HCT-based designs without layout or firmware changes. |
| Power-down protection on all I/O | Inputs and outputs tolerate 0–5.5 V when VCC = 0 V-prevents latch-up or damage during hot-insertion or backup-power switchover. |
| High noise immunity | VIH = 2.0 V and VIL = 0.8 V provide 1.2 V noise margin-resists EMI in motor-drive or switching-power environments. |
| Low dynamic noise (VOLP ≤ 0.8 V) | Minimizes ground bounce during simultaneous output transitions-critical for mixed-signal PCBs with ADCs or PLLs. |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |
|---|---|
Use Scenario: Isolating and conditioning sensor switch inputs before feeding microcontroller GPIOs in noisy factory environments. IC Role / Device Role / Timing Role: Level-shifting and signal conditioning NAND gate-converts floating or TTL-level switch signals into clean CMOS-compatible logic levels.

Use Value: 5.0 ns tPD and 0.8 V VIL ensure fast, reliable detection of short-duration keypresses even under ESD-prone user interface conditions. |
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 (Nexperia) | SO-14 package; identical DC/AC specs but lacks explicit 5.5 V input tolerance guarantee in datasheet. | Same logic function and timing; less suitable for hot-swap or dual-supply interfaces where input overvoltage may occur. | Select when board space allows SOIC and system does not require full 0–5.5 V input tolerance. |
| SN74VHCT00APW (TI) | Identical TSSOP-14 WB package and pinout; same VHCT family specs; minor differences in CPD (17 pF vs 16 pF) and VOLP test condition. | No functional difference; fully interchangeable in layout and firmware-only manufacturer sourcing distinction. | Select for TI-aligned BOMs or when dual-sourcing across onsemi and TI is required for supply resilience. |
Compared with 74VHCT00AM, the Nexperia 74HCT00D offers cost-effective SOIC packaging but reduced input voltage robustness, while the TI SN74VHCT00APW delivers identical performance and form factor-making it a true second-source option without design revision.

FAQ
What is the maximum supply voltage rating for the 74VHCT00AM?
The 74VHCT00AM has an absolute maximum VCC rating of +6.5 V per the datasheet's Maximum Ratings table. However, recommended operation is strictly 4.5 V to 5.5 V. Exceeding 5.5 V may cause accelerated aging or parametric shift, and operation above 6.5 V risks permanent damage. Always use regulated 5 V supplies with appropriate decoupling for reliable 74VHCT00AM performance.
Does the 74VHCT00AM support tri-state outputs?
No, the 74VHCT00AM does not support tri-state outputs. It features standard push-pull CMOS outputs only-each output actively drives HIGH or LOW depending on input logic states. The device includes power-down protection on all I/O pins, but no output-enable control or high-impedance mode is implemented. For bus-driving applications requiring tri-state capability, consider dedicated octal buffers like the 74VHCT244A instead of the 74VHCT00AM.
Can the 74VHCT00AM safely interface a 3.3 V microcontroller with a 5 V peripheral?
Yes-the 74VHCT00AM can safely interface a 3.3 V microcontroller with a 5 V peripheral. Its inputs accept 0–5.5 V regardless of VCC, and its outputs swing rail-to-rail (0 V to VCC). When powered at 5 V, the 74VHCT00AM interprets 3.3 V as a valid HIGH input (VIH = 2.0 V), and drives 5 V logic levels to the peripheral. This eliminates level-shifter components in mixed-voltage 74VHCT00AM-based interfaces.
What is the thermal resistance (θJA) of the 74VHCT00AM in its TSSOP-14 WB package?
The 74VHCT00AM in TSSOP-14 WB (Case 948G) has a specified junction-to-ambient thermal resistance (θJA) of 150°C/W under JEDEC-standard test conditions (76 mm × 114 mm, 2-oz copper, no airflow). This value assumes minimum pad spacing on FR4. Real-world θJA will improve with enhanced copper pour or thermal vias-critical for sustained 8 mA output loading in enclosed industrial enclosures where 74VHCT00AM may operate near +85°C ambient.
Is the 74VHCT00AM RoHS-compliant and lead-free?
Yes, the 74VHCT00AM is explicitly marked Pb-free and RoHS-compliant per the onsemi datasheet. The "G" suffix in the marking (e.g., ALYW) and "Pb-Free Package" note in the ordering table confirm compliance with EU RoHS Directive 2011/65/EU and related restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. This makes the 74VHCT00AM suitable for consumer, industrial, and medical products sold in regulated markets.
