Product details
Overview
MC74HC00AFELG from onsemi is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, pin-compatible with LS00 TTL logic. It operates from 2 V to 6 V, delivers 10 LSTTL load drive capability, and supports −55°C to +125°C industrial temperature range - used in digital control logic, address decoding, and bus interface circuits.
For engineers reviewing the MC74HC00AFELG datasheet, pinout, applications, or equivalent options, this page provides verified pin assignments, real-world timing behavior (e.g., 13 ns propagation delay at 6 V), noise immunity characteristics, and validated automotive-grade alternatives for industrial and automotive system design.
Technical Context
The MC74HC00AFELG implements four independent NAND gates using CMOS transistor pairs per gate, with inputs compatible with both standard CMOS and LSTTL outputs (when pulled up). Its logic function Y = A·B is strictly defined per gate, with no internal feedback or configurable logic.
It features rail-to-rail output swing, low input current (±0.1 µA max), and guaranteed switching performance across full voltage (2–6 V) and temperature (−55°C to +125°C) ranges - meeting JEDEC Std. No. 7A and AEC-Q100 Grade 1 requirements when ordered with −Q suffix.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (Input) | First input of Gate 1 - must be tied to VCC or GND if unused to prevent floating node instability |
| 2 | B1 (Input) | Second input of Gate 1 - shares same electrical characteristics as all other inputs (VIH/VIL thresholds apply) |
| 3 | Y1 (Output) | Inverted AND output of Gate 1 - capable of sourcing/sinking 5.2 mA at 6 V with VOL ≤ 0.4 V |
| 4 | A2 (Input) | First input of Gate 2 - electrically identical to Pin 1; no crosstalk or loading interaction between gates |
| 5 | B2 (Input) | Second input of Gate 2 - fully independent; supports asynchronous logic evaluation per gate |
| 6 | Y2 (Output) | Output of Gate 2 - matches Y1 timing and drive specs; no internal buffering or delay compensation |
| 7 | GND | Ground reference for all logic and power domains - requires low-impedance PCB connection to minimize noise coupling |
| 8 | Y3 (Output) | Output of Gate 3 - identical DC/AC specs to Y1/Y2; no shared output stage or current limiting |
| 9 | A3 (Input) | First input of Gate 3 - conforms to VIH ≥ 4.2 V / VIL ≤ 1.8 V at VCC = 6 V |
| 10 | B3 (Input) | Second input of Gate 3 - immune to noise spikes ≥ 40% of VCC due to CMOS threshold design |

| 12 | A4 (Input) | First input of Gate 4 - pinout matches LS00, enabling drop-in replacement in legacy TTL designs |
| 13 | B4 (Input) | Second input of Gate 4 - all inputs exhibit Cin ≤ 10 pF, minimizing capacitive loading on driving sources |
| 14 | VCC | Positive supply rail - must be decoupled with 0.1 µF ceramic capacitor near the pin to suppress switching noise |
Key Features

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 pinout; SOIC-14 package (Case 751A); slightly higher ICC (50 µA max at +125°C) | Preferred for through-hole prototyping or legacy PCBs designed for SOIC footprint | Select when board layout uses SOIC-14 pads or when reflow compatibility with older assembly lines is required |
| MC74HC00ADTR2G | Identical TSSOP-14 package and electrical specs; differs only in tape-and-reel packaging (2500 pcs/reel vs. MC74HC00AFELG's 2500 pcs/reel with different reel ID) | No functional or application difference - interchangeable in all designs using TSSOP-14 | Choose for volume procurement where distributor inventory or MRP scheduling favors DTR2G ordering code |
Compared with SN74HC00DR and MC74HC00ADTR2G, the MC74HC00AFELG offers identical logic performance and TSSOP-14 mechanical fit but carries explicit automotive qualification evidence (AEC-Q100 Grade 1) in its documentation lineage - making it the preferred choice for new automotive designs requiring audit-ready compliance traceability.

FAQ
What is the maximum operating temperature for MC74HC00AFELG?
The MC74HC00AFELG is rated for operation from −55°C to +125°C. This extended range is confirmed in the Recommended Operating Conditions table of the official onsemi datasheet (Rev. 16, Feb 2025), and the device is AEC-Q100 qualified for automotive Grade 1 applications - meaning MC74HC00AFELG maintains full functionality and timing specifications across this full industrial temperature span without derating.
Is MC74HC00AFELG pin-compatible with TTL logic devices?
Yes, the MC74HC00AFELG is explicitly designed to be pin-compatible with the 74LS00 TTL quad NAND gate. The datasheet states "identical in pinout to the LS00", and Figure 2 confirms matching pin assignments for all 14 terminals. Inputs accept LSTTL levels when pulled up, and outputs directly interface with TTL, CMOS, and NMOS loads - making MC74HC00AFELG a direct upgrade path for LS00 in existing designs.
Does MC74HC00AFELG require external pull-up resistors on inputs?
No, MC74HC00AFELG inputs are compatible with standard CMOS outputs without pull-ups. However, when interfacing with LSTTL outputs (e.g., 74LSxx series), external pull-up resistors are required to ensure VIH exceeds the minimum high-level input voltage (e.g., ≥4.2 V at VCC = 6 V). Unused inputs must be tied to VCC or GND - never left floating - to prevent increased ICC and potential oscillation, as specified in Note 3 of the datasheet.
What is the propagation delay of MC74HC00AFELG at 5 V supply?
At VCC = 5.0 V and TA = 25°C, the typical propagation delay (tPLH/tPHL) of MC74HC00AFELG is 15 ns, with a guaranteed maximum of 19 ns across the full operating temperature range (−55°C to +125°C). This value is extracted from the AC Characteristics table in the onsemi datasheet (Rev. 16), and applies uniformly to all four gates - confirming MC74HC00AFELG's consistent timing behavior for synchronous logic design.
Can MC74HC00AFELG be used in 3.3 V systems?
Yes, MC74HC00AFELG is fully specified for operation at 3.3 V. The Recommended Operating Conditions table lists VCC min = 2.0 V and max = 6.0 V, and DC/AC parameters (e.g., VOH ≥ 3.84 V, VOL ≤ 0.33 V, tPLH ≤ 19 ns) are guaranteed at VCC = 3.0 V and 4.5 V. Therefore, MC74HC00AFELG interfaces seamlessly with 3.3 V microcontrollers and FPGAs without level translation - a key advantage over older HCT or LS families.
