Product details
Overview
MC74HC00AFL1 from onsemi is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, pinout-compatible with LS00 TTL logic. It operates from 2 V to 6 V, delivers ±25 mA output drive per pin, and supports −55 °C to +125 °C industrial temperature range. It is used in digital control logic, level translation, and bus interface circuits where low-power, noise-immune CMOS switching is required.
For engineers reviewing the MC74HC00AFL1 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SOIC-14/TSSOP-14 package mapping, confirmed propagation delay (13 ns @ 6 V), input/output voltage compatibility with LSTTL/CMOS, and real-world use cases in industrial control and power management systems.
Technical Context
The MC74HC00AFL1 implements four independent NAND gates using silicon-gate CMOS process, ensuring rail-to-rail logic swing and high noise immunity. Each gate has identical electrical characteristics: VIH = 4.20 V (min) and VIL = 1.80 V (max) at VCC = 6.0 V, with guaranteed VOL ≤ 0.1 V and VOH ≥ 5.9 V under 20 µA load.
It features 32 FETs per device (8 equivalent gates), supports direct interfacing to CMOS, NMOS, and TTL loads (up to 10 LSTTL), and includes built-in ESD protection. Unused inputs must be tied to VCC or GND; outputs are not internally clamped and must remain open when unused.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 6.0 V - Enables single-supply operation across battery-powered and industrial 3.3 V/5 V systems. |
| Propagation Delay | 13 ns max @ VCC = 6.0 V - Supports >30 MHz toggle rates in synchronous logic paths. |
| Output Drive | ±25 mA per pin - Sufficient to directly drive LEDs, small relays, or fan-out to 10 LSTTL loads. |
| Input Leakage | ±1.0 µA max @ 6.0 V - Ensures stable logic levels with high-impedance pull-ups or long PCB traces. |
| Operating Temp | −55 °C to +125 °C - Qualified for extended industrial and automotive under-hood environments. |
| Power Dissipation | 500 mW (SOIC), 450 mW (TSSOP) - Limits thermal rise in dense logic arrays without forced cooling. |
| Input Capacitance | 10 pF max - Minimizes loading on preceding drivers and preserves signal edge integrity. |
Pinout & Package
MC74HC00AFL1 is available in SOIC-14 (Case 751A) and TSSOP-14 (Case 948G) packages. Both share identical 14-pin dual-inline pinout with VCC on pin 14 and GND on pin 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input A/B of NAND gates | Eight total inputs across four gates; each pair (e.g., pins 1&2) forms one NAND input set. |
| 3, 6, 8, 11 | Output Y of NAND gates | Four independent active-low outputs; no internal bus contention or shared output lines. |
| 7 | GND | Ground reference for all logic thresholds and supply return path; must be low-impedance. |
| 14 | VCC | Positive supply rail; decoupling capacitor (0.1 µF) required within 1 cm for stable AC performance. |
Key Features
| Feature | Design Value |
|---|---|
| LS00 Pin Compatibility | Direct drop-in replacement for 74LS00 in legacy TTL designs without layout change. |
| LSTTL Load Drive | Drives up to 10 LSTTL inputs per output - eliminates need for buffer stages in mixed-logic systems. |
| Wide Voltage Operation | 2–6 V supply range enables interoperability between 3.3 V microcontrollers and 5 V peripherals. |
| High Noise Immunity | CMOS threshold ratios (VIH/VIL ≈ 70%) reject >1.5 V of common-mode noise on inputs. |
| Pb-Free & RoHS Compliant | Meets JEDEC Std. 7A and AEC-Q100 for automotive-grade reliability and environmental compliance. |

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 | TI part with identical logic function, same 2–6 V VCC range, but 15 ns max tPD @ 6 V (vs. 13 ns). | Lower drive strength (±4 mA) limits fan-out to 2 LSTTL loads; unsuitable for direct relay driving. | Select SN74HC00DR only when TI supply chain alignment is prioritized over speed or drive capability. |
| 74VHC00M | ON Semiconductor's higher-speed variant: 7.5 ns max tPD @ 5 V, but narrower VCC range (2–5.5 V). | Not rated for 6 V operation or −55 °C start-up; excludes high-temp industrial deployments. | Choose 74VHC00M only when sub-10 ns timing is mandatory and 6 V/−55 °C requirements are absent. |
Compared with SN74HC00DR and 74VHC00M, the MC74HC00AFL1 uniquely balances 13 ns speed, 6 V tolerance, −55 °C cold-start capability, and ±25 mA drive-making it optimal for ruggedized embedded control where reliability and margin matter more than peak frequency.

FAQ
What is the maximum operating voltage for MC74HC00AFL1?
The MC74HC00AFL1 supports a DC supply voltage range of 2.0 V to 6.0 V, with absolute maximum rating of −0.5 V to +7.0 V. Operating continuously above 6.0 V risks permanent damage; design margins should maintain VCC ≤ 6.0 V per the Recommended Operating Conditions table in the official datasheet.
Is MC74HC00AFL1 compatible with 74LS00 in existing PCB layouts?
Yes, the MC74HC00AFL1 is pinout-identical to the 74LS00 and electrically compatible when pull-up resistors are used on inputs. Its CMOS inputs draw <1 µA, so standard 4.7 kΩ pull-ups ensure proper LSTTL-level recognition while eliminating DC loading issues present in bipolar TTL.
Does MC74HC00AFL1 require external pull-up resistors on inputs?
MC74HC00AFL1 inputs are CMOS-compatible and do not require pull-ups when driven by other CMOS outputs. However, when interfacing with LSTTL sources (e.g., 74LSxx), 4.7 kΩ pull-up resistors to VCC are needed to meet the VIH minimum of 4.20 V at 6 V supply - confirmed in the "Inputs Compatible with LSTTL Outputs" section of the datasheet.
What is the typical power dissipation of MC74HC00AFL1 at 5 V?
At VCC = 5.0 V and 25 °C, the MC74HC00AFL1 exhibits typical dynamic power dissipation of CPD × VCC² × f + ICC × VCC, where CPD = 22 pF and ICC = 1.0 µA. For a 1 MHz toggle rate, total power is ~0.55 mW per gate - well below the 500 mW SOIC package limit even with all four gates switching simultaneously.
Can unused inputs on MC74HC00AFL1 be left floating?
No - unused inputs on MC74HC00AFL1 must be tied to either VCC or GND. Floating CMOS inputs cause increased ICC, erratic switching, and potential thermal runaway due to partial conduction in the input stage. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level."
