Product details
Overview
74ALVC00BQ-Q100 from Nexperia is a quad 2-input NAND gate IC with Schmitt-trigger inputs, IOFF partial power-down capability, and AEC-Q100 Grade 1 automotive qualification. It operates from 1.65 V to 3.6 V supply, delivers propagation delay as low as 2.1 ns at 3.0–3.6 V, and supports ambient temperatures up to +125 °C. It is used in automotive body control modules for noise-immune logic interfacing between sensors and microcontrollers.
For engineers reviewing the 74ALVC00BQ-Q100 datasheet, 74ALVC00BQ-Q100 pinout, 74ALVC00BQ-Q100 application, or 74ALVC00BQ-Q100 equivalent, key selection criteria include IOFF-enabled system-level power sequencing, Schmitt-trigger input hysteresis for slow-edge signal conditioning, -40 °C to +125 °C operation, and DHVQFN14 package compatibility with AOI-capable SMT lines.
Technical Context
This device implements four independent 2-input NAND logic gates with Schmitt-trigger inputs on all channels, providing hysteresis (typically 0.3 V at VCC = 3.3 V) to reject noise on slow-rising/falling signals. Each gate output drives CMOS- or TTL-compatible loads with VOH ≥ 2.2 V and VOL ≤ 0.3 V under 24 mA sink/source conditions at VCC = 3.0 V.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting off-state leakage to ±10 μA and preventing backflow current during hot-insertion or partial power-down sequences. Input tolerance extends to 3.6 V regardless of VCC level, enabling mixed-voltage domain interfacing without level shifters.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00AQDRQ1 | No Schmitt-trigger inputs; standard CMOS inputs only | Requires external RC filtering for noisy automotive environments | Select when cost sensitivity outweighs noise immunity needs and board space allows filtering components |
| 74AUP1G00GW-Q100 | Single-gate variant in TSSOP5; no IOFF; lower drive strength (4 mA) | Not suitable for multi-channel parallel logic; limited to low-power, low-speed functions | Choose only for space-constrained single-gate applications where IOFF and 24 mA drive are unnecessary |

FAQ
Does the 74ALVC00BQ-Q100 support hot insertion into a live backplane?
Yes. The IOFF circuit ensures outputs are high-impedance when VCC = 0 V, preventing back-current flow during hot-plug events. Input tolerance to 3.6 V allows connection to powered buses prior to local VCC ramp-up, satisfying automotive hot-swap requirements per ISO 16750-2.
Can the DHVQFN14 package be reflowed using standard lead-free profiles?
Yes. The SOT762-1 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow with peak temperature up to 260 °C. Its side-wettable flanks are compatible with standard stencil designs and AOI systems calibrated for QFN packages.
What is the maximum clock frequency this device can reliably handle?
While not a clocked device, the 74ALVC00BQ-Q100 supports data toggle rates exceeding 200 MHz in buffered configurations due to its 2.1 ns typical propagation delay at 3.3 V. Real-world maximum frequency depends on load capacitance and signal integrity; 50 pF loading yields ~120 MHz practical limit.
Is the exposed thermal pad electrically connected internally?
No. The exposed pad in the DHVQFN14 (SOT762-1) package is not electrically connected to any internal node. Per datasheet note, it may remain floating or be connected to GND for thermal enhancement-but must not be tied to VCC or other potentials.
