Product details
Overview
MC74HC00AFR2 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 ±25 mA output drive per pin, exhibits 15 ns propagation delay at 4.5 V, and supports industrial temperature range (–55°C to +125°C). It serves as a fundamental combinational logic building block in digital control, interface translation, and system enable/disable circuits.
For engineers reviewing the MC74HC00AFR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SOIC-14 pin mapping, confirmed DC/AC electrical specs, real-world use context, and two rigorously cross-referenced alternative parts for logic-level design continuity.
Technical Context
The MC74HC00AFR2 implements four independent NAND gates in a single monolithic CMOS IC, each with symmetrical input structure and rail-to-rail output swing. Its inputs accept standard CMOS logic levels and-when pulled up-are compatible with LSTTL outputs, enabling mixed-logic interfacing without level shifters.
It features low input current (±0.1 µA max), high noise immunity, and JEDEC Std. 7A compliance. The device uses 32 FETs (8 equivalent gates) and includes ESD protection circuitry; unused inputs must be tied to VCC or GND to prevent floating-state instability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables operation from single Li-ion battery (3.3 V) up to dual-supply industrial rails (5 V), eliminating need for voltage regulators in many logic interfaces. |
| Propagation Delay (tPLH/tPHL) | 15 ns @ VCC = 4.5 V, CL = 50 pF - Supports reliable 33 MHz toggle-rate operation in synchronous logic paths with margin. |
| Output Drive Current | ±25 mA per pin - Sufficient to directly drive multiple LSTTL loads (up to 10) or small LEDs without external buffers. |
| Input Leakage Current | ±0.1 µA max @ VCC = 6.0 V - Ensures stable logic states in battery-powered systems with multi-year standby requirements. |
| Operating Temperature | –55°C to +125°C - Qualified for under-hood automotive, industrial PLC, and aerospace avionics environments without derating. |
| Input Capacitance | 10 pF max - Minimizes capacitive loading on driving stages, preserving signal integrity in high-speed fan-out configurations. |
Pinout & Package
MC74HC00AFR2 is supplied in a Pb-free, RoHS-compliant SOIC-14 (Case 751A) package measuring 8.75 mm × 3.95 mm × 1.75 mm, with 1.27 mm pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input A/B of NAND gates 1–4 | Dual-input logic terminals; each pair (e.g., pins 1 & 2) feeds one NAND gate; all inputs are CMOS-compatible with TTL pull-up support. |
| 3, 6, 8, 11 | Output Y of NAND gates 1–4 | Active-low open-drain–capable outputs; rail-to-rail swing ensures full logic-level compatibility with downstream CMOS/NMOS/TTL stages. |
| 7 | GND | Ground reference for all internal circuitry and I/O; must be connected to system ground plane with low-inductance path. |
| 14 | VCC | Positive supply terminal; requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| LS00 Pin Compatibility | Direct drop-in replacement for 74LS00 in legacy designs-no PCB change required when upgrading to lower-power, wider-voltage CMOS logic. |
| Wide Supply Range (2–6 V) | Eliminates need for separate 5 V regulators in mixed-voltage systems; supports direct connection to 3.3 V microcontroller GPIOs or 5 V sensor buses. |
| High Noise Immunity | CMOS input threshold (VIH ≥ 3.15 V @ 4.5 V) and hysteresis-like behavior reduce susceptibility to EMI in motor-drive or switching-power environments. |
| Pb-Free & RoHS Compliance | Meets global environmental directives; qualified for lead-free reflow profiles (peak 260°C) without reliability degradation. |
Applications
| Industrial Control Logic | Microcontroller Interface Buffering |

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; identical AC/DC specs, same SOIC-14 footprint, but rated only to +85°C (not +125°C). | Suitable for commercial-grade consumer electronics; not recommended for under-hood or industrial thermal environments. | Select SN74HC00DR only if operating temperature stays below 85°C and AEC-Q100 is not required. |
| 74VHC00M | ON Semiconductor's higher-speed VHC variant; 7.5 ns propagation delay @ 5 V, but reduced noise margin and narrower VIH/VIL windows. | Better for high-frequency clock gating; less tolerant of noisy supply or marginal input transitions. | Choose 74VHC00M when speed >15 MHz is critical and board-level noise is tightly controlled. |
Compared with SN74HC00DR and 74VHC00M, the MC74HC00AFR2 offers the broadest temperature range and highest noise immunity among industry-standard HC-family quad NANDs-making it optimal for mission-critical industrial and automotive logic where reliability trumps raw speed.

FAQ
What is the exact package type and lead count for MC74HC00AFR2?
The MC74HC00AFR2 is packaged in a Pb-free, RoHS-compliant SOIC-14 (Small Outline Integrated Circuit, 14-pin) package, Case 751A, with 1.27 mm lead pitch. This matches the industry-standard footprint of 74LS00 and other 14-pin logic ICs, enabling direct PCB substitution without layout changes.
Does MC74HC00AFR2 support true 3.3 V operation with guaranteed timing?
Yes. The MC74HC00AFR2 is fully specified down to 2.0 V supply, and its propagation delay is guaranteed at 30 ns @ VCC = 3.0 V (≤85°C). At 3.3 V, typical tPLH/tPHL is ~22 ns-well within timing budgets for most 3.3 V microcontroller interfaces and FPGA glue logic.
Can MC74HC00AFR2 drive LED indicators directly?
Yes. With ±25 mA output drive capability per pin and VOL ≤ 0.26 V @ 4 mA sink, the MC74HC00AFR2 can directly drive standard 2 mA–10 mA indicator LEDs using a series resistor. For example, at VCC = 5 V and 5 mA LED current, a 820 Ω resistor yields safe, bright illumination without external drivers.
Is MC74HC00AFR2 qualified for automotive applications?
The base MC74HC00AFR2 is not AEC-Q100 qualified; however, its pin- and function-identical variant NLV74HC00ADR2G is automotive-qualified (AEC-Q100 Grade 1, –40°C to +125°C) and PPAP-capable. Both share the same die and process-only marking and test screening differ.
What happens if an input on MC74HC00AFR2 is left floating?
Leaving any input floating on the MC74HC00AFR2 risks metastability, excessive supply current, and erratic output behavior due to CMOS high-impedance inputs. The datasheet explicitly requires unused inputs to be tied to VCC or GND-never left open-to ensure deterministic logic states and prevent shoot-through current in internal circuitry.
