Product details
Overview
74HC00DR2G from onsemi is a quad 2-input NAND gate in SOIC-14 package, operating across 2.0–6.0 V supply, delivering 10 LSTTL load drive capability, <1.0 µA input leakage, and propagation delay as low as 13 ns at 6.0 V - used for digital logic inversion and combinational control in industrial timing and interface circuits.
For engineers reviewing the 74HC00DR2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range, output drive strength, propagation delay vs. VCC, input compatibility with TTL/CMOS, and Pb-free SOIC-14 packaging for surface-mount reliability.
Technical Context
The 74HC00DR2G implements four independent CMOS NAND gates using high-performance silicon-gate technology, with inputs tolerant of both CMOS and LSTTL logic levels when pullup resistors are applied. Its architecture ensures rail-to-rail output swing and high noise immunity due to inherent CMOS threshold characteristics.
It operates over –55°C to +125°C, supports static and dynamic operation up to 35 MHz (typical), and features ESD protection rated at 2000 V HBM. Each gate has identical pinout to legacy 74LS00 but with significantly lower power consumption and higher noise margin.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input A/B of NAND gates | Eight total inputs - each pair (e.g., pins 1&2, 4&5, etc.) feeds one of four independent NAND functions. |
| 3, 6, 8, 11 | Output Y of NAND gates | Four open-drain–compatible outputs - rail-to-rail CMOS swing, capable of sourcing/sinking 25 mA. |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance connection to minimize switching noise. |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-speed operation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC00DR | Same logic function and SOIC-14 package; TI version specifies 20 µA max ICC at 6 V (vs. onsemi's 40 µA), tighter VOH/VOL tolerances at 4 mA load. | Preferred in battery-critical designs where quiescent current below 20 µA is mandatory; slightly higher cost. | Select SN74HC00DR if sub-20 µA ICC is required and TI qualification documentation is mandated by OEM. |
| MC74HC00ADTR2G | Identical onsemi die in TSSOP-14 (948G); same electrical specs but 5.1 mm × 4.5 mm footprint, 0.65 mm pitch - requires layout revision. | Suitable for space-constrained boards; thermal resistance 6.1 mW/°C derating above 65°C differs from SOIC's 7 mW/°C. | Choose MC74HC00ADTR2G only when board area savings justify rework; not drop-in compatible with 74HC00DR2G layout. |
Compared with SN74HC00DR and MC74HC00ADTR2G, the 74HC00DR2G offers optimal balance of industrial temperature support, proven SOIC-14 manufacturability, and cost-effective Pb-free compliance - making it the default choice for new designs prioritizing supply chain stability and assembly yield.

FAQ
What is the maximum operating frequency supported by the 74HC00DR2G?
The 74HC00DR2G does not specify a hard maximum clock frequency, but its propagation delay (13 ns max at 6.0 V) and transition time (13 ns max) support reliable operation up to approximately 35 MHz in typical fan-out-1 configurations. Actual usable frequency depends on load capacitance, supply stability, and PCB routing - for 50 pF loads, AC characterization confirms stable toggling at 20 MHz with margin.
Is the 74HC00DR2G pin-compatible with the older 74LS00?
Yes, the 74HC00DR2G is fully pin-compatible with the 74LS00 in SOIC-14 packaging - identical pin 1–14 assignments including VCC (pin 14), GND (pin 7), and all input/output positions. However, the 74HC00DR2G requires no external pullups for TTL compatibility and draws significantly less quiescent current than the bipolar LS version.
Can unused inputs on the 74HC00DR2G be left floating?
No - unused inputs on the 74HC00DR2G must be tied to a defined logic level (VCC or GND) to prevent oscillation, increased power consumption, or erratic output behavior. Floating CMOS inputs can drift into the linear region, causing shoot-through current and potential thermal stress. The datasheet explicitly mandates termination for all unused inputs.
Does the 74HC00DR2G support mixed-voltage operation between inputs and outputs?
No - the 74HC00DR2G operates from a single VCC supply (2.0–6.0 V); all inputs and outputs are referenced to that same rail. It does not support true mixed-voltage I/O like dual-supply translators. Input voltage must stay within 0 V to VCC, and output swing is rail-to-rail - level shifting requires external circuitry if interfacing with different domain voltages.
What is the meaning of "DR2G" in the 74HC00DR2G part number?
The "DR2G" suffix identifies the specific packaging and shipping configuration: "D" = SOIC-14 package, "R2" = 2500-unit tape-and-reel, and "G" = Pb-free (RoHS-compliant) finish. This matches onsemi's official ordering nomenclature and distinguishes it from variants like "DTR2G" (TSSOP-14) or non-Pb-free versions ending in "D".
