Product details
Overview
74HC30D/AUJ from Nexperia is an 8-input CMOS NAND gate in SO14 package, operating from 2.0 V to 6.0 V supply, delivering propagation delay as low as 12 ns at VCC = 6.0 V and CL = 50 pF, with ±25 mA output drive capability. It serves as a high-noise-immunity combinational logic element in digital control, address decoding, and bus arbitration circuits.
For engineers reviewing the 74HC30D/AUJ datasheet, 74HC30D/AUJ pinout, 74HC30D/AUJ application, or 74HC30D/AUJ equivalent, key selection considerations include input voltage compatibility (CMOS-level), -40 °C to +125 °C industrial temperature range, SO14 mechanical footprint, and static current draw below 40 μA at VCC = 6.0 V.
Technical Context
The 74HC30D/AUJ implements a single 8-input NAND function using standard CMOS transistor pairs, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Its logic behavior follows strict Boolean NAND: output Y = NOT(A·B·C·D·E·F·G·H).
It features rail-to-rail output swing, input thresholds referenced to VCC (VIH = 0.7×VCC min, VIL = 0.3×VCC max), and guaranteed operation across full industrial temperature range without derating up to +125 °C. Latch-up immunity exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 8-input NAND gate - single-output combinational logic with active-low output assertion |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered designs |
| Propagation Delay (tpd) | 12 ns typical at VCC = 6.0 V, CL = 50 pF - enables reliable timing in sub-25 MHz synchronous logic |
| Output Drive | ±25 mA - sufficient to directly drive LED indicators, small MOSFET gates, or TTL inputs |
| Input Thresholds | VIH ≥ 4.2 V, VIL ≤ 1.8 V at VCC = 6.0 V - ensures robust noise margin >1.6 V under worst-case conditions |
| Operating Temperature | -40 °C to +125 °C - qualified for industrial control, motor drives, and power supply monitoring |
| Power Dissipation | CPD = 15 pF - dynamic power scales predictably with frequency and switching node count |

Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (2.0 V–6.0 V) | Enables direct use in 3.3 V microcontroller systems and legacy 5 V industrial controllers without voltage translation |
| Input clamp diodes | Permits safe interface to 12 V control signals via external 10 kΩ current-limiting resistors, avoiding damage during overvoltage transients |
| High noise immunity | Guaranteed 40 % VCC noise margin at VCC = 6.0 V due to tightly controlled VIH/VIL thresholds and hysteresis-free design |
| Latch-up immunity >100 mA | Meets JESD78 Class II Level B, ensuring robustness against accidental ground-bounce or supply-rail collapse events |
| ESD protection (HBM >2000 V) | Reduces need for external ESD protection on board-level I/O lines, lowering BOM count in space-constrained designs |
Applications
| Industrial PLC Input Conditioning | Microcontroller Address Decoding |
|---|---|

Use Value: Enables deterministic bus ownership transfer in <30 ns, outperforming software-based arbitration and reducing bus turnaround overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT30D | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical SO14 pinout and timing | Required when interfacing directly to legacy 5 V TTL outputs without level shifters | Select 74HCT30D only if driving source is strictly TTL; 74HC30D/AUJ preferred for CMOS or mixed-voltage systems |
| SN74HC30DR | Same logic function and specs, but TI-manufactured SO14 package with different thermal resistance (RθJA = 120 K/W vs Nexperia's 105 K/W) | Valid for drop-in replacement where TI sourcing is mandated; requires verification of thermal margin in high-density layouts | Use SN74HC30DR only under TI-approved supply chain programs; verify thermal performance at 125 °C ambient |
Compared with 74HCT30D and SN74HC30DR, the 74HC30D/AUJ offers superior noise immunity in mixed-signal environments due to tighter VIH/VIL ratios, lower typical ICC (2.0 μA vs 5.0 μA), and optimized ESD robustness per JS-001 Class 2, making it preferred for new industrial designs.

FAQ
What is the maximum operating supply voltage for 74HC30D/AUJ?
The absolute maximum supply voltage for 74HC30D/AUJ is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per Nexperia's datasheet Rev. 10. Operation above 6.0 V voids parametric guarantees and risks accelerated aging. The 74HC30D/AUJ must not be biased beyond 7.0 V even transiently, as specified in Table 4 (Limiting Values).
Does 74HC30D/AUJ support 3.3 V logic systems?
Yes, 74HC30D/AUJ fully supports 3.3 V operation: VIH minimum is 2.31 V (0.7 × 3.3 V) and VIL maximum is 0.99 V (0.3 × 3.3 V) at 25 °C, providing >1.3 V noise margin. Static current remains below 20 μA at VCC = 3.3 V, and propagation delay is 19 ns typical - confirming robust interoperability with 3.3 V microcontrollers and FPGAs.
Are pins 9, 10, and 13 on 74HC30D/AUJ internally connected?
No, pins 9, 10, and 13 on 74HC30D/AUJ are explicitly designated "n.c." (not connected) in Table 2 of the datasheet. They have no internal bond wires or silicon connection. These pins may be left floating, tied to GND, or tied to VCC based on mechanical or EMI mitigation needs - but no electrical function is affected either way.
Can 74HC30D/AUJ drive a 50 pF capacitive load at 10 MHz?
Yes, 74HC30D/AUJ can reliably drive a 50 pF load at 10 MHz. With CPD = 15 pF and typical tpd = 15 ns at VCC = 4.5 V, dynamic power dissipation is calculated as PD ≈ 15 pF × (4.5 V)² × 10 MHz = 3.04 mW - well within the 500 mW total package limit. Output transition times remain <22 ns, ensuring clean edges without ringing.
What is the thermal resistance (RθJA) of the SO14 package used by 74HC30D/AUJ?
The SO14 (SOT108-1) package for 74HC30D/AUJ has a typical junction-to-ambient thermal resistance (RθJA) of 105 K/W under standard JEDEC test conditions (1-layer board, 1 in² copper pad). Derating begins linearly at 10.1 mW/K above 100 °C ambient, as specified in Table 4 footnote [2]. This value assumes no additional heatsinking or airflow.
