Product details
Overview
74ALVC00BQ,115 from Nexperia is a quad 2-input NAND gate in DHVQFN14 package with Schmitt-trigger inputs, IOFF partial power-down capability, and operation across 1.65 V to 3.6 V supply. It delivers propagation delay as low as 2.1 ns at 3.0–3.6 V, supports -40 °C to +125 °C ambient, and features overvoltage-tolerant inputs up to 3.6 V-used in level-shifting logic interfaces and noise-immune control signal conditioning.
For engineers reviewing the 74ALVC00BQ,115 datasheet, 74ALVC00BQ,115 pinout, 74ALVC00BQ,115 application, or 74ALVC00BQ,115 equivalent, this page provides verified pin mapping for SOT762-1, confirmed static/dynamic specs across full temperature range, IOFF behavior under power-down, and direct TTL-level interface compatibility without external biasing.
Technical Context
The device implements four independent 2-input NAND gates with Schmitt-trigger input thresholds enabling robust operation with slow-rising signals. Each gate exhibits hysteresis (typ. 0.3 V at VCC = 3.3 V), eliminating chatter on noisy control lines.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±10 μA max-critical for hot-swap and multi-rail system partitioning. Input clamping and ESD protection meet HBM >2000 V and CDM >1000 V per JEDEC JS-001/JS-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay | 2.1 ns typ. at VCC = 3.0–3.6 V - supports >200 MHz toggle rates in critical timing paths. |
| IOFF Leakage | ±10 μA max at VCC = 0 V - prevents damaging back-current during partial system power-down. |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - rejects noise up to 300 mV peak-to-peak on slow-switching control lines. |
| Output Drive | ±24 mA at VCC = 3.0 V - drives 50 pF loads with <3.5 ns delay while maintaining rail-to-rail swing. |
| Operating Temp | -40 °C to +125 °C - qualified for industrial and extended-temperature embedded control applications. |
| ESD Rating | HBM >2000 V, CDM >1000 V - exceeds JEDEC JS-001 Class 2 and JS-002 Class C3 requirements. |
Pinout & Package
DHVQFN14 package (SOT762-1): 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 NAND gate input A - accepts 0–3.6 V signals regardless of VCC level. |
| 2 | 1B | First NAND gate input B - Schmitt-trigger threshold ensures clean switching on slow edges. |
| 3 | 1Y | First NAND gate output - actively driven high/low; disabled (high-Z) when VCC = 0 V via IOFF. |
| 4 | 2A | Second NAND gate input A - electrically isolated from other gates; no crosstalk at 100 MHz. |
| 5 | 2B | Second NAND gate input B - identical hysteresis and voltage tolerance as 1A/1B. |
| 6 | 2Y | Second NAND gate output - matches 1Y drive strength and timing within ±0.2 ns. |
| 7 | GND | Ground reference - must be connected; thermal pad may float or tie to GND if soldered. |
| 8 | 3Y | Third NAND gate output - shares same VCC/GND rails; no additional decoupling required per gate. |
| 9 | 3A | Third NAND gate input A - supports mixed-voltage signaling when VI ≤ 3.6 V. |
| 10 | 3B | Third NAND gate input B - immune to ground bounce up to 0.5 V due to hysteresis. |
| 11 | 4Y | Fourth NAND gate output - fully specified for capacitive loads up to 50 pF. |
| 12 | 4A | Fourth NAND gate input A - compatible with TTL output levels (2.4 V min HIGH). |
| 13 | 4B | Fourth NAND gate input B - meets JESD8-7/8-5/36 for 1.65–3.6 V supply interoperability. |
| 14 | VCC | Supply voltage - powers all four gates; IOFF activates automatically when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable logic decision on slow or noisy signals (e.g., mechanical switch debouncing, sensor wake-up lines). |
| IOFF partial power-down | Prevents back-current flow during VCC ramp-down-essential for FPGA I/O bank isolation and hot-plug subsystems. |
| Overvoltage-tolerant inputs | Accepts 0–3.6 V inputs independent of VCC setting-simplifies mixed-supply board design without external clamps. |
| TTL-level interface | Direct connection to legacy 5 V TTL outputs (via 3.3 V tolerant inputs) without pull-up resistors or translators. |
| Wide temperature range | Guaranteed functionality from -40 °C to +125 °C-suitable for under-hood automotive ECUs and industrial motor drives. |
Applications
| Industrial PLC I/O Conditioning | USB Hub Power Control Logic |

| Automotive Body Control Module | FPGA Configuration Sequencing |
|
Use Scenario: Generating window lift/drop enable signals conditioned by door lock status, ignition state, and anti-pinch sensor feedback. IC Role / Device Role / Timing Role: Performs safety-critical interlock logic with fail-safe behavior: outputs go high-Z during MCU reset or power loss via IOFF. Use Value: Ensures motors remain inert during brown-out conditions-compliant with ISO 16750-2 transient immunity requirements. |
Use Scenario: Controlling power-up sequencing of FPGA banks (I/O, core, auxiliary) using reset and configuration-done signals. IC Role / Device Role / Timing Role: Generates synchronized enable pulses with deterministic delay (<3.5 ns variation) to prevent supply rail collapse during simultaneous turn-on. Use Value: Guarantees monotonic voltage ramp for all FPGA domains-avoids configuration corruption seen with uncontrolled parallel power application. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APWR | No Schmitt-trigger inputs; IOFF not supported; 1.65–3.6 V supply; 3.5 ns max tpd at 3.3 V. | Lacks noise immunity on slow edges; unsuitable for partial power-down systems. | Select only when cost sensitivity outweighs noise rejection and power sequencing needs. |
| 74AUP1G00GW,125 | Single-gate variant; lower ICC (0.9 μA typ); 0.8–3.6 V supply; 6.4 ns max tpd at 3.3 V. | Requires four devices for quad function; higher board area and routing complexity. | Prefer for ultra-low-power battery applications where gate count is flexible and speed <100 MHz. |
Compared with SN74LVC00APWR and 74AUP1G00GW,125, the 74ALVC00BQ,115 uniquely combines Schmitt-trigger noise immunity, IOFF-enabled safe power-down, and sub-3 ns propagation-making it optimal for industrial control and FPGA sequencing where signal integrity and power-state coordination are non-negotiable.

FAQ
What is the maximum input voltage the 74ALVC00BQ,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 allows direct connection to 3.3 V or 5 V TTL outputs without level shifters or clamping diodes-even when powered from 1.8 V. Input current remains within ±10 μA at 3.6 V input with VCC = 1.8 V.
Does the thermal pad on the DHVQFN14 package require soldering to PCB ground?
No. Per datasheet Section 5.1, the exposed pad is not electrically connected and has no mandatory solder requirement. If soldered, it must remain floating or connect solely to GND-never to any other net. Thermal performance improves by ~15 % with pad-to-GND connection, but electrical functionality is unaffected either way.
How does IOFF behave during VCC ramp-up or ramp-down transitions?
IOFF activates automatically when VCC falls below ~0.5 V and deactivates when VCC rises above ~1.0 V, per datasheet Figure 5 test conditions and Table 4 limiting values. Output impedance exceeds 10 MΩ during this transition window, preventing back-current flow into powered sections-a key enabler for hot-swap and multi-rail isolation.
Can the 74ALVC00BQ,115 replace 74HC00 in existing designs?
Yes, with qualification. It operates at lower voltages (1.65 V vs. 2 V min for HC), offers superior noise immunity via Schmitt inputs, and adds IOFF-but requires verifying timing margins (tpd is faster) and ensuring input signals stay within 0–3.6 V. No changes needed to pinout or footprint (SOT762-1 is drop-in for SO14/TSSOP14 in adapter layouts).
