Product details
Overview
74HCT30PW,112 from Nexperia is an 8-input NAND gate in TSSOP14 package, designed for TTL-level input compatibility at 4.5 V to 5.5 V supply, delivering 4.32 V VOH at -4.0 mA output load and 0.26 V VOL at 4.0 mA, with propagation delay of 16–42 ns across temperature. It serves as a high-density logic combiner in industrial control I/O expansion and digital signal conditioning circuits.
For engineers reviewing the 74HCT30PW,112 datasheet, 74HCT30PW,112 pinout, 74HCT30PW,112 application, or 74HCT30PW,112 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), guaranteed operation from -40 °C to +125 °C, and low-power CMOS design with ICC ≤ 40 μA at VCC = 5.5 V.
Technical Context
This device implements a single 8-input NAND function using silicon-gate CMOS technology, with inputs tolerant of overvoltage via integrated clamp diodes and current-limiting resistor support. Its TTL-level input thresholds ensure direct interfacing with legacy 5 V logic families without level-shifting.
The logic core operates with rail-to-rail output swing (VOH ≥ 3.7 V, VOL ≤ 0.4 V at full load) and exhibits consistent timing behavior across -40 °C to +125 °C, supported by JESD7A compliance and latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 8-input NAND: outputs LOW only when all eight inputs are HIGH; enables compact Boolean expression reduction in combinational logic. |
| Supply Voltage Range | 4.5 V to 5.5 V: matches standard 5 V TTL systems while ensuring noise margin and stable switching. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max: guarantees reliable recognition of TTL logic levels without external biasing. |
| Propagation Delay | 16–42 ns (VCC = 4.5 V, CL = 50 pF): supports synchronous operation up to ~15 MHz in critical path applications. |
| Output Drive | ±4.0 mA at VCC = 4.5 V: sufficient to drive multiple 74-series inputs or small capacitive loads (< 50 pF). |
| Operating Temperature | -40 °C to +125 °C: qualified for extended industrial environments including motor control enclosures and power supply monitoring. |
| Power Dissipation | ICC ≤ 40 μA at VCC = 5.5 V (static): enables low-quiescent-current designs in always-on supervisory functions. |

| 11 (G) | Data input | Seventh logic input; identical electrical behavior to Pins 1–6; used in 8-bit status aggregation. |
| 12 (H) | Data input | Eighth and final logic input; completes full 8-input function; enables single-gate implementation of complex enable conditions. |
| 13 (n.c.) | Not connected | Unbonded die pad; no internal connection; must not be soldered or tied to any net. |
| 14 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail; requires local 100 nF ceramic decoupling within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min / VIL = 0.8 V max ensures plug-and-play integration with legacy 5 V microcontrollers and peripheral ICs. |
| Wide temperature range | Guaranteed operation from -40 °C to +125 °C supports deployment in under-hood automotive modules and industrial PLC backplanes. |
| Input clamp diodes | Enables use of series current-limiting resistors for interfacing to voltages > VCC, simplifying mixed-voltage system design. |
| Low static power | ICC ≤ 40 μA at VCC = 5.5 V reduces standby current in battery-backed monitoring circuits and always-on logic supervisors. |
| ESD robustness | HBM > 2000 V and CDM > 1000 V allow safe handling during manual assembly and reduce field failure risk in noisy factory environments. |
Applications
| Industrial I/O Expansion | Digital Power Sequencing |
|---|---|
|
Use Scenario: Aggregating eight discrete sensor fault flags into a single system-level alert line in programmable logic controllers. IC Role / Device Role / Timing Role: 8-input NAND acts as active-low OR gate (via De Morgan's law), asserting fault when any input goes HIGH. Use Value: Eliminates need for discrete diode-OR networks or additional logic stages, reducing BOM count and board area by 60%. |
Use Scenario: Enabling a DC-DC converter only after eight upstream rails have stabilized, verified by supervisor IC outputs. IC Role / Device Role / Timing Role: Serves as final enable gate whose output controls MOSFET driver enable pin with sub-50 ns response. Use Value: Ensures strict power-up ordering without FPGA or microcontroller intervention, improving system reliability. |
| Legacy Bus Interface Logic | Test Mode Selection |
|
Use Scenario: Decoding eight address bits to generate chip-select signals for vintage 8-bit microprocessor peripherals (e.g., Z80, 6502). IC Role / Device Role / Timing Role: Functions as address decoder element with propagation delay < 28 ns, meeting tight 200 ns bus cycle timing. Use Value: Maintains full compatibility with TTL bus timing margins while consuming < 0.1 mW static power. |
Use Scenario: Combining eight DIP switch settings to activate a diagnostic test mode in embedded instrumentation hardware. IC Role / Device Role / Timing Role: Provides deterministic test-enable assertion only when all eight switches are set to ON (HIGH). Use Value: Prevents accidental test activation; eliminates software dependency and enables hardware-only diagnostics. |
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,653 | SO14 package (SOT108-1); 3.9 mm body width; 1.27 mm lead pitch; slightly higher thermal resistance (10.1 mW/K derating above 100 °C). | Better suited for through-hole prototyping or wave-soldered industrial boards where TSSOP reflow is unavailable. | Select when board assembly uses traditional SMT placement with larger pad spacing or requires higher mechanical robustness. |
| SN74HCT30DR | Texas Instruments part in SOIC-14; VIH/VIL identical; tpd = 18–45 ns (CL = 50 pF); ICC = 40 μA max at 5.5 V; JEDEC JESD7A compliant. | Validated for use in TI-based reference designs and automotive-qualified systems where TI sourcing is mandated. | Choose when designing into TI ecosystem platforms or requiring dual-sourcing with documented cross-compatibility reports. |

FAQ
Can 74HCT30PW,112 operate reliably at 3.3 V supply?
No - the 74HCT30PW,112 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH = 2.0 V min) become marginal, and VOH drops below 2.4 V, risking downstream logic misreads. Use 74HC30PW for 2.0–6.0 V wide-range operation instead.
Are pins 9, 10, and 13 internally bonded or truly unconnected?
Pins 9, 10, and 13 are confirmed not connected (n.c.) per Nexperia's official pin description table. They have no internal bond wire or die connection; routing traces to them introduces unnecessary parasitic capacitance and ESD vulnerability.
Does this device support hot insertion or live circuit connection?
No - the 74HCT30PW,112 lacks hot-swap protection circuitry. Applying VCC before GND, or connecting inputs while VCC is absent, violates absolute maximum ratings (e.g., VI < –0.5 V or > VCC + 0.5 V) and risks latch-up or permanent damage.
How does the input clamp diode affect interface design with 12 V control signals?
The internal clamp diodes allow safe interface to 12 V signals when a series current-limiting resistor ≥ 560 Ω is used - limiting clamp current to < 20 mA per diode. This avoids external protection components while preserving signal integrity for slow-edge control lines.
