Product details
Overview
74ALVC08BQ,115 from Nexperia is a quad 2-input AND gate IC with Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operation across 1.65 V to 3.6 V supply. It delivers propagation delay as low as 1.0 ns at 2.7 V, supports -40 °C to +125 °C ambient, and features overvoltage-tolerant inputs up to 3.6 V - used in industrial control logic interfacing and mixed-voltage signal conditioning.
For engineers reviewing the 74ALVC08BQ,115 datasheet, 74ALVC08BQ,115 pinout, 74ALVC08BQ,115 application, or 74ALVC08BQ,115 equivalent, key selection criteria include its DHVQFN14 package thermal performance, IOFF leakage < ±10 μA at VCC = 0 V, guaranteed Schmitt-trigger hysteresis, and JEDEC-compliant voltage-level interoperability with TTL and 1.8/2.5/3.3 V systems.
Technical Context
This device implements four independent 2-input AND gates with Schmitt-trigger input buffers on all eight inputs, enabling robust operation with slow-rising or noisy signals. Each gate exhibits identical logic behavior per IEC 60617-12 and complies with JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C/JESD36 (2.7–3.6 V) interface standards.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ≤ ±10 μA and preventing bus contention during hot-swap or partial-power-down sequences. Static and dynamic characteristics are fully characterized across -40 °C to +125 °C, with propagation delay tpd ranging from 1.0 ns (2.7 V) to 6.1 ns (1.65 V) and CPD = 24 pF per gate at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate with independent Schmitt-trigger inputs on all A/B pins |
| Supply Voltage Range | 1.65 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains |
| Propagation Delay (tpd) | 1.0 ns typical at VCC = 2.7 V - ensures timing-critical combinational logic meets sub-2 ns path budgets |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - prevents damaging backflow during system power sequencing |
| Input Voltage Tolerance | Up to 3.6 V regardless of VCC - allows safe connection to higher-voltage buses without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |

Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, exposed thermal pad (non-soldered by default), 14 terminals, pin 1 index marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First AND gate input A - Schmitt-trigger buffered for noise margin ≥ 0.35×VCC |
| 2 | VCC | Main supply rail - powers all four gates and internal IOFF circuitry |
| 3 | 4B | Fourth AND gate input B - electrically isolated from other inputs until logic evaluation |
| 4 | 4A | Fourth AND gate input A - shares same Schmitt threshold as 1A/2A/3A |

| 10 | 2B | Second AND gate input B - input leakage ≤ ±0.1 μA at VCC = 3.6 V |
| 11 | 2Y | Second AND gate output - matched drive strength and timing to 1Y/3Y/4Y |
| 12 | 3A | Third AND gate input A - shares same VIH/VIL thresholds and hysteresis as all inputs |
| 13 | GND | Ground reference - return path for all supply and signal currents; thermal pad may be left floating |
| 14 | 3Y | Third AND gate output - completes quad gate set; identical AC/DC specs to other Y outputs |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable logic decision with slow or noisy edges; hysteresis ≥ 0.35×VCC prevents chatter |
| IOFF partial power-down | Disables outputs at VCC = 0 V, limiting backflow to ±10 μA - critical for hot-plug and multi-rail sequencing |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V regardless of VCC setting - eliminates need for external clamping diodes |
| JEDEC-compliant voltage ranges | Validated for 1.65–1.95 V (JESD8-7), 2.3–2.7 V (JESD8-5), and 2.7–3.6 V (JESD8C/JESD36) interfaces |
| Thermal-enhanced DHVQFN | SOT762-1 package provides 9.6 mW/K derating above 98 °C - improves reliability in compact enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.

|---|---|---|---|
| SN74LVC08APWR | Same logic function and pinout; IOFF not implemented; max VCC = 3.6 V; no Schmitt inputs | Lacks noise immunity on slow edges; unsuitable for unfiltered sensor inputs or long traces | Select only if system has clean, fast-rising signals and full power-down isolation is unnecessary |
| 74AUP1G08GW,125 | Single-gate variant in SOT353; VCC range 0.8–3.6 V; lower ICC (0.9 μA typ); no IOFF | Requires four separate packages for quad functionality; lacks thermal enhancement and bus-isolation capability | Prefer for ultra-low-power always-on monitoring nodes where space permits discrete placement |
Compared with SN74LVC08APWR and 74AUP1G08GW,125, the 74ALVC08BQ,115 uniquely combines Schmitt-trigger noise rejection, IOFF-enabled hot-swap safety, and DHVQFN thermal efficiency - making it the only choice for high-reliability, mixed-voltage industrial control logic.

FAQ
What is the maximum input voltage the 74ALVC08BQ,115 can tolerate when VCC = 1.8 V?
The device tolerates inputs up to 3.6 V regardless of VCC level, per datasheet Table 4 and Section 2. This overvoltage capability eliminates external clamping components when interfacing with higher-voltage peripherals, provided input current remains within ±50 mA limits.
Does the DHVQFN14 package require soldering of the exposed thermal pad?
No - the thermal pad (pin 1 index area) has no electrical or mechanical requirement to be soldered. If connected, it must remain electrically floating or tied to GND; soldering without proper grounding risks thermal stress or shorting to adjacent terminals.
How does the IOFF feature behave during power sequencing when VCC ramps from 0 V to 3.3 V?
IOFF activates when VCC drops below ~0.8 V and deactivates once VCC exceeds ~1.2 V. During ramp-up, outputs remain in high-impedance state until VCC stabilizes above the functional threshold, preventing glitch generation or bus contention in multi-rail systems.
Can the 74ALVC08BQ,115 replace 74HC08 in an existing 5 V design?
No - it is not rated for 5 V operation. Its absolute maximum VCC is +4.6 V but recommended operating range ends at 3.6 V. For 5 V systems, use 74HC08 or 74HCT08; for 3.3 V migration, 74ALVC08BQ,115 offers superior speed, lower ICC, and IOFF vs. older families.
