Product details
Overview
74AHCT30PW,118 from Nexperia is an 8-input NAND gate in TSSOP14 package, designed for high-speed digital logic interfacing with TTL-level inputs and CMOS-compatible outputs. It operates from 4.5 V to 5.5 V, delivers propagation delays as low as 3.3 ns (CL = 15 pF), supports −40 °C to +125 °C ambient range, and features Schmitt-trigger inputs for noise immunity-used in bus arbitration, enable control, and address decoding in industrial microcontroller systems.
For engineers reviewing the 74AHCT30PW,118 datasheet, 74AHCT30PW,118 pinout, 74AHCT30PW,118 application, or 74AHCT30PW,118 equivalent, this device is selected when precise 8-input logic gating with TTL-compatible input thresholds, sub-10 ns timing at 5 V, and thermal-enhanced TSSOP packaging are required for deterministic combinational logic in embedded control subsystems.
Technical Context
The 74AHCT30PW,118 implements a single 8-input NAND function using Si-gate CMOS technology compliant with JEDEC Standard No. 7-A. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure direct compatibility with legacy LSTTL outputs without level shifting.
All eight inputs incorporate Schmitt-trigger action, providing hysteresis of typically 0.3 V to suppress noise-induced switching. The output stage drives ±8 mA at VCC = 4.5 V, supporting fan-out to multiple 74-series loads while maintaining rail-to-rail VOH/VOL performance across temperature.
Key Specifications

Applications
| Industrial Bus Arbitration | Microcontroller Peripheral Enable |
|---|---|
Use Scenario: Resolving contention among multiple masters on a shared parallel data bus in programmable logic controllers. IC Role / Device Role / Timing Role: 8-input NAND acts as priority encoder input combiner, asserting bus grant only when highest-priority master requests access and no higher-priority request is active. Use Value: Eliminates need for discrete resistor networks or additional logic stages, reducing BOM count and layout area by 30% vs. dual 4-input NAND solution. | Use Scenario: Enabling/disabling a group of SPI peripherals (ADC, DAC, sensor hub) based on system mode register bits. IC Role / Device Role / Timing Role: NAND gate decodes three mode bits and five peripheral select bits into a single active-low chip-enable signal. Use Value: Provides deterministic setup/hold timing (tPLH ≤ 8.0 ns) for synchronous peripheral activation, avoiding metastability in multi-clock-domain systems. |
| Power Sequencing Control | Fault-Safe System Reset |
Use Scenario: Validating presence and stability of eight independent DC rails before releasing main system reset in telecom line cards. IC Role / Device Role / Timing Role: Each input monitors a dedicated power-good signal; output holds reset asserted until all rails are valid. Use Value: Guarantees coordinated power-up sequence with <10 ns skew between rail validations, preventing latch-up in ASICs and FPGAs. | Use Scenario: Generating a hardware reset pulse when any of eight safety-critical sensors (temperature, current, voltage) exceeds threshold. IC Role / Device Role / Timing Role: Inputs tied to open-drain fault outputs; NAND output triggers immediate system shutdown via reset controller. Use Value: Achieves fail-safe response time <15 ns from first fault detection, meeting SIL-2 functional safety timing constraints. |

FAQ
Is 74AHCT30PW,118 compatible with 3.3 V logic systems?
No. The 74AHCT30PW,118 is specified only for 4.5 V to 5.5 V supply operation and requires TTL-level inputs (VIH ≥ 2.0 V). Applying VCC = 3.3 V violates recommended operating conditions and may cause undefined output states or excessive ICC. For 3.3 V systems, use 74AHC30PW,118 instead.
Can unused inputs be left floating?
No. All eight inputs must be actively driven HIGH or LOW. Floating inputs induce increased ICC, erratic output behavior, and potential thermal overstress due to partial conduction in input-stage transistors. Tie unused inputs to VCC or GND via ≤1 kΩ resistors to ensure stable logic states and minimize power consumption.
What is the maximum capacitive load for guaranteed timing performance?
The 74AHCT30PW,118 guarantees tpd ≤ 8.0 ns (max) at CL = 50 pF and VCC = 5.0 V. Loads exceeding 50 pF increase propagation delay nonlinearly and may violate setup/hold windows in synchronous circuits. For >50 pF loads, add a buffer stage or verify timing margin using the CPD = 12 pF value in dynamic power calculations.
Does the TSSOP14 package require thermal vias on the exposed pad?
No. The 74AHCT30PW,118 in SOT402-1 (TSSOP14) has no exposed thermal pad-unlike QFN variants. Its thermal path relies solely on leads and mold compound. PCB layout should prioritize short, wide traces to VCC/GND and local 100 nF ceramic decoupling within 3 mm of Pin 14 and Pin 7, respectively.
