Product details
Overview
74AHCT08PW/AUJ from Nexperia is a quad 2-input AND gate IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, -40 °C to +125 °C temperature range, overvoltage-tolerant inputs (up to 5.5 V), and TSSOP14 package. It serves as a level-translating logic gate in mixed-voltage digital control systems such as industrial PLC I/O modules.
For engineers reviewing the 74AHCT08PW/AUJ datasheet, 74AHCT08PW/AUJ pinout, 74AHCT08PW/AUJ application, or 74AHCT08PW/AUJ equivalent, key selection factors include its TTL-level input compatibility, 14-terminal TSSOP package footprint, guaranteed propagation delay ≤9.0 ns at 5 V/50 pF, and robust ESD protection (HBM >2000 V, CDM >1000 V).
Technical Context
The 74AHCT08PW/AUJ implements four independent AND gates with Schmitt-trigger inputs for noise immunity and overvoltage tolerance up to 5.5 V - enabling safe interfacing between 3.3 V and 5 V domains. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure reliable recognition of legacy 5 V logic signals.
Propagation delays are balanced across all gates (tpd ≤9.0 ns max at VCC = 4.5–5.5 V, CL = 50 pF), and static output drive capability supports ±8 mA at VOH/VOL specifications. The device meets JESD 78 Class II Level A latch-up immunity (>100 mA) and operates across full industrial and extended automotive-grade temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Independent input B terminals - enable dual-input logic evaluation per gate |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | CMOS-compatible outputs - actively driven HIGH/LOW with rail-to-rail swing referenced to VCC/GND |
| 7 | GND | Ground reference (0 V) - required return path for all internal logic and output current |
| 14 | VCC | Positive supply input - powers all four gates; must be decoupled locally with 100 nF ceramic capacitor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT08D | SO14 package (SOT108-1); 3.9 mm body width; 1.27 mm lead pitch; higher thermal resistance than TSSOP | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints; less suitable for high-density layouts | Select when board space permits larger footprint and hand-soldering is required |
| SN74AHCT08PWR | Texas Instruments part in 14-pin TSSOP; identical logic function and TTL thresholds; VCC range 4.5–5.5 V; same -40 °C to +125 °C rating | Validated in TI's automotive-grade qualification program; different ESD specs (HBM 2000 V, CDM 1000 V - same as Nexperia) | Choose for TI-design ecosystems or when dual-sourcing across vendors is mandated |
Compared with 74AHCT08PW/AUJ, the 74AHCT08D offers mechanical compatibility with legacy SOIC layouts but sacrifices board-area efficiency, while SN74AHCT08PWR delivers identical electrical performance with alternate supply-chain assurance - neither is pin-compatible without footprint adaptation.

FAQ
What is the input voltage threshold behavior of the 74AHCT08PW/AUJ?
The 74AHCT08PW/AUJ features TTL-compatible input thresholds: VIH is guaranteed ≥2.0 V and VIL is guaranteed ≤0.8 V at VCC = 4.5–5.5 V. This allows direct interface with legacy 5 V TTL and LS logic families without level shifting. Input pins are overvoltage tolerant up to 5.5 V regardless of VCC, supporting mixed-voltage domain bridging. The 74AHCT08PW/AUJ does not support CMOS-level inputs like its AHC counterpart.
Does the 74AHCT08PW/AUJ support operation at 3.3 V supply?
No, the 74AHCT08PW/AUJ is specified only for VCC = 4.5 V to 5.5 V. Its TTL input thresholds require minimum 4.5 V to guarantee correct logic interpretation; operation below 4.5 V violates recommended conditions and may result in undefined output states. For 3.3 V systems, use the 74AHC08PW variant instead. The 74AHCT08PW/AUJ is not rated for 3.3 V operation.
What is the maximum capacitive load the 74AHCT08PW/AUJ can drive reliably?
The 74AHCT08PW/AUJ is characterized for CL = 15 pF and 50 pF loads in dynamic testing, with propagation delay specified up to 50 pF. While it can drive heavier loads, timing margins degrade beyond 50 pF - for loads >50 pF, add series termination or buffer stages. Output drive strength is ±8 mA, limiting total fan-out to ~10 standard 74AHCT inputs (each ~10 pF). The 74AHCT08PW/AUJ's CPD is 12.0 pF, used to calculate dynamic power dissipation.
How does the Schmitt-trigger input action benefit the 74AHCT08PW/AUJ in noisy environments?
The Schmitt-trigger inputs on the 74AHCT08PW/AUJ provide built-in hysteresis (~0.3–0.5 V typical), preventing multiple output transitions caused by slow-rising or noisy input signals. This eliminates need for external RC filtering in applications like switch debouncing, sensor signal conditioning, or long-trace industrial wiring. The 74AHCT08PW/AUJ maintains clean, single-edge outputs even with input rise/fall times up to 20 ns/V - critical for reliability in EMI-heavy settings.
Is the 74AHCT08PW/AUJ qualified for automotive applications?
The 74AHCT08PW/AUJ is rated for -40 °C to +125 °C operation and meets JESD 78 Class II Level A latch-up immunity, but Nexperia does not classify it as automotive-qualified per AEC-Q100. It lacks formal automotive stress testing and qualification documentation. For automotive use, select Nexperia's AEC-Q100 qualified equivalents (e.g., 74AHCT08PW-Q100) or verify system-level compliance independently. The 74AHCT08PW/AUJ remains suitable for non-safety-critical body electronics where customer validation is performed.
