Product details
Overview
MC74HC00AFG from onsemi is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, pinout-compatible with LS00 TTL logic. It operates across 2–6 V supply, delivers 10 LSTTL loads, and supports −55°C to +125°C industrial temperature range - used in digital control logic, level translation, and bus interface circuits.
For engineers reviewing the MC74HC00AFG datasheet, pinout, applications, or equivalent options, this page provides verified functional specs, SOIC-14 package details, automotive-grade qualification status, and real-world design context for logic-level compatibility and noise-immune operation.
Technical Context
The MC74HC00AFG implements four independent NAND gates with CMOS input structure compatible with both standard CMOS and LSTTL outputs (with pullup resistors). Each gate exhibits rail-to-rail output swing and high noise immunity due to its silicon-gate process.
It meets JEDEC Std No. 7A, supports AEC-Q100 qualification (−Q suffix variants), and features low input current (±0.1 µA max at 6 V), 10 pF max input capacitance, and propagation delays as low as 13 ns at VCC = 6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - four independent gates per package, each implementing Y = A·B̅ logic |
| Supply Voltage Range | 2.0 V to 6.0 V - enables interoperability across 3.3 V and 5 V systems without level shifters |
| Propagation Delay | 13 ns max at VCC = 6 V - ensures timing predictability in high-speed combinatorial logic paths |
| Output Drive | 10 LSTTL loads - sufficient to drive legacy TTL inputs directly without buffers |
| Input Leakage | ±0.1 µA max at 6 V - minimizes static power draw and prevents unintended node biasing |
| Operating Temperature | −55°C to +125°C - qualified for extended industrial and under-hood automotive environments |
| ESD Rating | >2000 V HBM - robust handling during board assembly and field service |
Pinout & Package

| 1, 2, 4, 5, 9, 10, 12, 13 | Input (A1/B1/A2/B2/A3/B3/A4/B4) | Dedicated NAND input pairs - pins grouped per gate: (1,2), (4,5), (9,10), (12,13) |
| 3, 6, 8, 11 | Output (Y1/Y2/Y3/Y4) | CMOS rail-to-rail outputs - each drives one NAND result; no internal pullups/pulldowns |
| 7 | GND | Ground reference for all logic and supply return - must be low-impedance connection |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF) required within 10 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Industrial Control Logic | Power Supply Sequencing |
|---|---|
Use Scenario: Implementing enable/disable logic for multi-rail DC-DC converters in programmable logic controllers. IC Role / Device Role / Timing Role: NAND gate used as active-low enable combiner - two inputs monitor voltage-good signals, output controls MOSFET gate driver. Use Value: Ensures safe power-up order by preventing downstream rails from activating before primary supplies stabilize. |
Use Scenario: Generating synchronized reset pulses during cold-start of embedded microcontrollers. IC Role / Device Role / Timing Role: NAND configured as edge-triggered pulse generator - one input tied high, other driven by RC-delayed reset line. Use Value: Delivers precise 100 ns–1 µs reset extension without external monostable ICs or firmware overhead. |
| Automotive Body Electronics | Legacy System Interface |
Use Scenario: Interfacing modern 3.3 V microcontroller GPIOs to 5 V lamp driver ICs in door module assemblies. IC Role / Device Role / Timing Role: Level-translating NAND gate - inputs accept 3.3 V logic, outputs swing rail-to-rail to 5 V for TTL-compatible drivers. Use Value: Eliminates discrete resistor-divider networks while maintaining noise margin and ESD robustness per AEC-Q100. |
Use Scenario: Replacing obsolete 74LS00 in retrofitted instrumentation panels with aging TTL-based displays. IC Role / Device Role / Timing Role: Pinout-identical drop-in replacement - identical SOIC-14 footprint and truth table behavior. Use Value: Reduces BOM complexity and extends product lifecycle without PCB redesign or firmware changes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC00DR | Same logic function and SOIC-14 package; TI part has slightly higher ICC max (50 µA vs 40 µA at 6 V) | Not AEC-Q100 qualified; rated only to +85°C commercial temp range | Select when automotive qualification is unnecessary and cost sensitivity favors TI's distribution channels |
| 74VHC00M | Higher speed (8 ns @ 5 V), lower CPD (16 pF), but narrower VCC range (2–5.5 V) | Not qualified to AEC-Q100; lacks −55°C low-temp rating | Prefer for high-frequency clock gating where sub-10 ns delay is critical and supply is strictly 5 V |
Compared with SN74HC00DR and 74VHC00M, the MC74HC00AFG uniquely combines full industrial temperature range, AEC-Q100 capability (via −Q variants), and guaranteed 2–6 V operation - making it the only choice for automotive body control modules requiring long-term reliability across extreme ambient conditions.

FAQ
What is the maximum operating temperature for MC74HC00AFG?
The MC74HC00AFG is rated for operation from −55°C to +125°C. This full industrial temperature range is confirmed in the Recommended Operating Conditions table of the official onsemi datasheet (Rev. 16, Feb 2025), and applies to all SOIC-14 packaged variants including MC74HC00AFG. The device maintains specified VOH/VOL and propagation delay performance across this range.
Is MC74HC00AFG pin-compatible with the original 74LS00?
Yes, the MC74HC00AFG is explicitly stated in the datasheet to be "identical in pinout to the LS00". Pin assignments for inputs (A1–B4), outputs (Y1–Y4), VCC (pin 14), and GND (pin 7) match the 74LS00 exactly. This allows direct replacement in existing LS00-based designs without layout modification - provided supply voltage and loading conditions remain within HC family specifications.
Does MC74HC00AFG support 3.3 V logic systems?
Yes, MC74HC00AFG fully supports 3.3 V operation. Its recommended VCC range is 2.0 V to 6.0 V, and all DC and AC specifications - including VIH (min 2.1 V at VCC = 3.0 V), VOL (max 0.26 V), and tPLH (max 19 ns) - are guaranteed at 3.3 V. It interfaces seamlessly with 3.3 V CMOS microcontrollers and FPGA I/O banks.
What is the meaning of the 'FG' suffix in MC74HC00AFG?
The 'FG' suffix in MC74HC00AFG indicates a Pb-free (RoHS-compliant), SOIC-14 package (Case 751A) with standard industrial temperature grade (−55°C to +125°C). Per onsemi's ordering information, 'F' denotes SOIC-14 packaging and 'G' signifies Pb-free finish - consistent with the marking diagram showing 'XXXXXXG' and the 'G' in the generic marking field.
Can MC74HC00AFG drive LSTTL loads directly?
Yes, MC74HC00AFG is specified to drive up to 10 LSTTL loads, as stated in the Features section and confirmed by its output drive capability (IOH/IOL) values: ±4.0 mA at VCC = 4.5 V and ±5.2 mA at VCC = 6.0 V. This meets the LSTTL input current requirement (IIL ≤ 0.4 mA, IIH ≤ 0.02 mA), enabling direct fanout without buffer stages.
