Product details
Overview
MC74HC00AFEL from onsemi is a quad 2-input NAND gate in TSSOP-14 package, implementing high-performance silicon-gate CMOS logic with 2–6 V supply operation, <1 µA input leakage, and 13 ns propagation delay at 6 V. It interfaces directly to CMOS, NMOS, and TTL loads and is used in digital control logic, address decoding, and enable/disable circuitry.
For engineers reviewing the MC74HC00AFEL datasheet, pinout, applications, or equivalent options, this page delivers verified pin functions, JEDEC-compliant noise immunity, automotive-grade AEC-Q100 qualification (−Q variant), and real-world timing behavior across temperature and voltage ranges.
Technical Context
The MC74HC00AFEL implements four independent NAND gates in a single monolithic CMOS die with 32 FETs total. Each gate features symmetrical input thresholds (VIH = 4.2 V, VIL = 1.8 V @ VCC = 6 V) and rail-to-rail output swing (VOH ≥ 5.9 V, VOL ≤ 0.1 V @ VCC = 6 V, IOUT = ±20 µA).
It operates across −55°C to +125°C with guaranteed AC performance: tPLH/tPHL ≤ 19 ns @ VCC = 4.5 V, TA ≤ 85°C; input capacitance ≤ 10 pF; and power dissipation capacitance of 22 pF per buffer. The device is fully compliant with JEDEC Std No. 7A and supports LSTTL load driving (10 loads).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND - enables compact implementation of combinational logic, inverters (via tied inputs), and basic control gating |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V microcontrollers driving 5 V peripherals) |
| Propagation Delay | 13 ns max @ VCC = 6 V, TA ≤ 25°C - ensures reliable timing in clocked digital subsystems up to ~30 MHz toggle rate |
| Output Drive | ±25 mA DC per pin - drives 10 LSTTL loads without external buffers, simplifying board-level fanout design |
| Input Leakage Current | ±1.0 µA max @ VCC = 6 V, TA ≤ 125°C - minimizes static current draw in battery-backed or low-power hold modes |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive, industrial control, and extended-environment applications |
| ESD Rating | HBM > 2000 V - provides robust handling during assembly and field service without additional protection circuitry |
Pinout & Package
TSSOP-14 (Case 948G), 4.4 mm × 5.0 mm body, 0.65 mm pitch, lead-free (Pb-free) and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (Input) | First input of Gate 1 - must be actively driven or tied to VCC/GND; floating inputs cause increased ICC and noise susceptibility |
| 2 | B1 (Input) | Second input of Gate 1 - paired with Pin 1 to form NAND function Y1 = A1·B1 |
| 3 | Y1 (Output) | Inverted AND output of Gate 1 - compatible with CMOS/NMOS/TTL inputs; open-drain use requires external pull-up |
| 4 | A2 (Input) | First input of Gate 2 - electrically isolated from other gates; shares no internal nodes |
| 5 | B2 (Input) | Second input of Gate 2 - identical electrical characteristics to Pins 1 and 2 |
| 6 | Y2 (Output) | Output of Gate 2 - capable of sourcing/sinking 25 mA; layout routing should minimize capacitive loading for timing-critical paths |
| 7 | GND | Digital ground reference - must be connected to low-impedance system ground plane; decoupling capacitor (0.1 µF) required within 5 mm |
| 8 | Y3 (Output) | Output of Gate 3 - same drive strength and voltage levels as Y1/Y2/Y4; usable as active-low enable signal |
| 9 | A3 (Input) | First input of Gate 3 - matches VIH/VIL specs across full temperature range; no hysteresis |
| 10 | B3 (Input) | Second input of Gate 3 - supports rise/fall rates down to 400 ns @ VCC = 6 V without oscillation |
| 11 | Y4 (Output) | Output of Gate 4 - final gate in quad configuration; suitable for reset generation or status flag assertion |
| 12 | A4 (Input) | First input of Gate 4 - unused inputs must be tied to VCC or GND to prevent shoot-through current |
| 13 | B4 (Input) | Second input of Gate 4 - all four gates operate independently with identical propagation and transition times |
| 14 | VCC | Positive supply rail - requires local 0.1 µF ceramic + 4.7 µF bulk capacitance; voltage must remain within 2–6 V during operation |
Key Features
| Feature | Design Value |
|---|---|

| Low Dynamic Power | CPD = 22 pF per buffer allows predictable dynamic power calculation: PD = CPD × VCC² × f + ICC × VCC |
| AEC-Q100 Qualified Variant | MC74HC00ADTR2G−Q version meets automotive stress testing requirements for temperature cycling, HTOL, and ESD |
| Pb-Free & RoHS Compliant | Meets global environmental regulations; compatible with standard SnAgCu reflow profiles (peak 260°C, 10 sec) |

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 | SOIC-14 package (Case 751A); identical logic, timing, and DC specs; 116 °C/W θJA vs. 150 °C/W for TSSOP | Preferred for through-hole prototyping or legacy board designs with SOIC footprints; lower thermal resistance suits higher ambient temp | Select when board layout uses SOIC-14 land pattern or thermal budget exceeds 150 °C/W junction-to-ambient limit |
| 74HC00PW,118 | TSSOP-14 from Nexperia; same pinout and VCC range; VOH spec tighter (min 4.4 V @ 4.5 V) but tPLH slightly slower (15 ns @ 4.5 V) | Suitable for cost-sensitive consumer designs where 2 ns timing margin is acceptable; identical RoHS/Pb-free compliance | Choose for second-source assurance in non-automotive applications where 13 ns propagation is not mandatory |
Compared with SN74HC00DR and 74HC00PW,118, the MC74HC00AFEL offers the lowest propagation delay in TSSOP-14 format and is the only variant qualified to AEC-Q100 for automotive use - making it optimal for space-constrained, thermally demanding, or safety-relevant deployments.

FAQ
What is the maximum operating temperature for the MC74HC00AFEL?
The MC74HC00AFEL is rated for operation from −55°C to +125°C. This full industrial temperature range is validated per JEDEC JESD22-A108 and supported by guaranteed AC/DC specifications across all corners - including 19 ns max propagation delay at +85°C and ±1.0 µA input leakage at +125°C. The MC74HC00AFEL maintains functionality and reliability under continuous thermal stress within these limits.
Does the MC74HC00AFEL support 3.3 V logic systems?
Yes, the MC74HC00AFEL operates reliably at 3.3 V supply (VCC = 3.3 V). At this voltage, VIH is guaranteed ≥ 2.1 V and VIL ≤ 0.9 V, providing 1.2 V noise margin against typical 3.3 V CMOS outputs. VOH ≥ 3.28 V and VOL ≤ 0.33 V (IOUT = ±4.0 mA) ensure clean interfacing with downstream 3.3 V receivers. The MC74HC00AFEL is widely deployed in mixed-voltage FPGA/CPU peripheral logic.
Is the MC74HC00AFEL pin-compatible with older 74LS00 devices?
Yes, the MC74HC00AFEL is pinout-identical to the 74LS00, as confirmed in the onsemi datasheet: "The MC74HC00A is identical in pinout to the LS00." All 14 pins map one-to-one, including VCC (Pin 14), GND (Pin 7), and identical gate input/output assignments. However, the MC74HC00AFEL requires pull-up resistors for LSTTL input compatibility and does not tolerate input voltages exceeding VCC + 0.5 V.
What packaging and marking details define the MC74HC00AFEL?
The MC74HC00AFEL is supplied in TSSOP-14 package (Case 948G), marked "HC 00A" with date code and Pb-free indicator ('G' suffix). Dimensions are 5.0 mm × 4.4 mm × 1.2 mm max height, 0.65 mm lead pitch. The 'FEL' suffix denotes tape-and-reel packaging (2500 units/reel), Pb-free finish, and compliance with RoHS Directive 2011/65/EU. The MC74HC00AFEL uses standard SnAgCu reflow profiles.
How does the MC74HC00AFEL handle unused inputs?
Unused inputs on the MC74HC00AFEL must be tied to either VCC or GND - never left floating. Floating inputs increase quiescent supply current (ICC), induce oscillation due to noise coupling, and degrade noise immunity. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level." For example, tying A4 and B4 to GND disables Gate 4 while preserving stability of the remaining three gates. This requirement applies to every MC74HC00AFEL unit in operation.
