Product details
Overview
74HC30DB,118 from Nexperia is an 8-input CMOS NAND gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, with propagation delay of 12 ns (VCC = 6.0 V, CL = 50 pF), output drive capability of ±4.0 mA, and guaranteed operation from −40 °C to +125 °C. It serves as a high-density logic combiner in digital control buses, address decoding, and enable gating for industrial microcontroller peripherals.
For engineers reviewing the 74HC30DB,118 datasheet, 74HC30DB,118 pinout, 74HC30DB,118 application, or 74HC30DB,118 equivalent, this page delivers verified functional identity, validated SO14 pin mapping, confirmed static/dynamic electrical specs across temperature, and real-world use context for logic-level signal aggregation and bus arbitration.
Technical Context
The 74HC30DB,118 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 inputs accept CMOS-level thresholds (VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V), ensuring compatibility with 3.3 V and 5 V logic families.
It features rail-to-rail output swing (VOH ≥ 4.4 V, VOL ≤ 0.26 V at VCC = 4.5 V, IO = ±4.0 mA), low static ICC (≤ 2.0 μA typical), and dynamic CPD of 15 pF - enabling predictable power estimation (PD = CPD × VCC² × fi × N) in clocked or data-path applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 8-input NAND: outputs LOW only when all eight inputs are HIGH; enables compact bus-enable and multi-signal arbitration logic. |
| Supply Voltage Range | 2.0 V to 6.0 V: supports direct interface with 3.3 V microcontrollers and legacy 5 V systems without level shifters. |
| Propagation Delay | 12 ns (typ.) at VCC = 6.0 V, CL = 50 pF: ensures timing-critical combinational logic meets sub-25 ns setup windows in 40 MHz control paths. |
| Output Drive | ±4.0 mA (IOH/ IOL): sufficient to drive 10 LSTTL loads or directly fan out to multiple 74HC-series inputs without buffering. |
| Operating Temperature | −40 °C to +125 °C: qualified for under-hood industrial PLC modules, motor drive control boards, and power supply sequencers. |
| Input Clamp Diodes | Integrated: allows safe connection of inputs to voltages > VCC (e.g., 12 V sensor signals) when series current-limiting resistors are used. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V: enhances robustness during PCB handling and field deployment in noisy factory environments. |
Pinout & Package
74HC30DB,118 is supplied in SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First of eight independent CMOS logic inputs; accepts 0–VCC voltage levels with defined VIH/VIL thresholds. |
| 2 (B) | Data input | Second logic input; electrically identical to Pin 1; no internal differentiation between A–H pins. |
| 3 (C) | Data input | Third logic input; shares same input capacitance (CI = 3.5 pF) and leakage (< ±0.1 μA) as all inputs. |
| 4 (D) | Data input | Fourth logic input; clamped via on-chip diodes to GND and VCC for overvoltage tolerance. |
| 5 (E) | Data input | Fifth logic input; referenced to GND; VI = 0 V to VCC defines valid logic states. |
| 6 (F) | Data input | Sixth logic input; no internal pull-up/down; requires external termination for unused pins. |
| 7 (GND) | Ground reference | Primary 0 V return path for all internal circuitry and output current sinking. |
| 8 (Y) | Output | Single CMOS push-pull output; drives HIGH to ≥4.4 V (VCC = 4.5 V) or LOW to ≤0.26 V under 4 mA load. |
| 9 (n.c.) | Not connected | No internal bond wire or silicon connection; must remain unconnected per datasheet guidance. |
| 10 (n.c.) | Not connected | Electrically isolated; floating or tied to GND/VCC has no effect on functionality. |
| 11 (G) | Data input | Seventh logic input; positioned adjacent to H and VCC for layout symmetry in dense routing. |
| 12 (H) | Data input | Eighth and final logic input; completes full 8-input NAND function; identical electrical behavior to A–F. |
| 13 (n.c.) | Not connected | Unused terminal; no internal connection; avoid soldering or routing to prevent parasitic coupling. |
| 14 (VCC) | Supply voltage | Positive supply rail; decoupling capacitor (100 nF ceramic) recommended within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (2.0–6.0 V) | Eliminates need for separate 3.3 V/5 V logic families in mixed-supply systems; reduces BOM count. |
| CMOS low power (ICC ≤ 2.0 μA typ.) | Enables always-on status monitoring in battery-backed industrial controllers without measurable quiescent drain. |
| Input clamp diodes | Permits direct interface to 12 V sensors or open-collector signals using simple series resistors-no external diodes required. |
| Latch-up immunity > 100 mA | Guarantees robustness against transient ground bounce or supply glitches in motor-drive adjacent PCBs. |
| −40 °C to +125 °C operation | Validated for use in automotive engine-control proximity modules and industrial inverters without derating. |
Applications
| Industrial Bus Enable Logic | Microcontroller Address Decoding |
|---|---|
Use Scenario: Enabling/disabling communication on RS-485 or CAN transceiver buses based on multi-signal arbitration. IC Role / Device Role / Timing Role: 8-input NAND acts as a programmable bus gate: LOW output enables driver enable pin only when all 8 system-ready flags are asserted. Use Value: Reduces discrete logic count by replacing four 2-input NANDs; eliminates timing skew between parallel decode paths. |
Use Scenario: Selecting peripheral memory or I/O devices using upper address bits in 8-bit MCU systems. IC Role / Device Role / Timing Role: Combines A8–A15 address lines to generate chip-select signals for up to eight memory-mapped peripherals. Use Value: Achieves deterministic <12 ns propagation delay across all eight inputs-critical for meeting 40 MHz bus timing budgets. |
| Power Sequencing Control | Factory Automation Safety Interlock |
Use Scenario: Validating pre-charge completion across eight DC-DC converter rails before releasing main power. IC Role / Device Role / Timing Role: Inputs monitor individual "rail OK" signals; output drives enable line to downstream regulators only when all eight are stable. Use Value: Ensures fail-safe sequencing: any single rail fault forces output HIGH → disables downstream power, preventing cascade failure. |
Use Scenario: Monitoring emergency stop, door interlock, light curtain, and six other safety inputs in CNC machine control. IC Role / Device Role / Timing Role: Acts as AND-of-inverts: all eight safety inputs must be HIGH (safe state) to keep output LOW and permit motion. Use Value: Provides hardware-level voting logic with no software dependency; meets SIL-2 functional safety requirements when combined with redundancy. |
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 |
|---|---|---|---|
| 74HCT30DB,118 | TTL-compatible inputs (VIH = 2.0 V min); otherwise identical SO14 pinout, timing, and drive. | Better suited for mixed 5 V TTL/CMOS systems where input thresholds must match legacy 74LS logic. | Select when interfacing directly to 74LS or older microcontrollers with weak HIGH drive; not needed for pure CMOS designs. |
| SN74HC30DR | Same logic function and specs, but TI SO14 package (PW) has slightly different thermal resistance (7.3 mW/K derating above 81 °C vs. Nexperia's 10.1 mW/K above 100 °C). | Identical functional replacement; minor thermal margin difference matters only in sustained >100 °C ambient applications. | Use when TI sourcing preference or dual-sourcing strategy applies; verify thermal design margin if operating near 125 °C. |
Compared with 74HC30DB,118, the 74HCT30DB,118 offers lower input threshold compatibility at the cost of reduced noise margin, while SN74HC30DR provides identical logic performance with a divergent thermal derating profile-requiring explicit thermal validation in high-ambient deployments.

FAQ
What is the maximum clock frequency supported by the 74HC30DB,118?
The 74HC30DB,118 is a combinational logic gate-not a clocked device-so it has no defined clock frequency. Its usable toggle rate depends on propagation delay (12 ns typical at VCC = 6.0 V) and system-level timing margins. For reliable operation in repetitive switching, ensure input pulse widths exceed tpd + tt (≈35 ns), supporting up to ~20 MHz data rates in non-critical paths.
Can unused inputs be left floating?
No. All eight inputs (A–H) must be actively driven HIGH or LOW; floating inputs cause increased ICC, erratic output behavior, and potential latch-up due to undefined CMOS gate bias. Tie unused inputs directly to VCC or GND using short traces-do not rely on pull-up/down resistors unless impedance matching is required.
Is the 74HC30DB,118 suitable for automotive applications?
No. Although rated for −40 °C to +125 °C, the 74HC30DB,118 is not AEC-Q100 qualified and lacks automotive-specific stress testing, failure mode analysis, or PPAP documentation. It is intended for industrial and commercial use only; automotive designs require explicitly qualified parts such as the 74HC30-Q100.
How does the input clamp diode affect external resistor selection?
When interfacing to voltages > VCC (e.g., 12 V sensor), the internal clamp diode conducts into VCC. A series current-limiting resistor must limit IIK to ≤±20 mA (absolute max). For 12 V input and VCC = 5 V, minimum R = (12 V − 5.5 V) / 20 mA = 325 Ω; 1 kΩ is recommended for margin and noise immunity.
