Nexperia USA Inc. 74LVC11BQ-Q100X

Overview

74LVC11BQ-Q100 from Nexperia is an automotive-grade triple 3-input AND gate IC in DHVQFN14 package, operating from 1.2 V to 3.6 V supply, with inputs tolerant up to 5.5 V, propagation delay as low as 1.5 ns at VCC = 3.0 V, and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control and body electronics logic interfacing.

For engineers reviewing the 74LVC11BQ-Q100 datasheet, 74LVC11BQ-Q100 pinout, 74LVC11BQ-Q100 application, or 74LVC11BQ-Q100 equivalent, this device serves as a low-voltage, high-speed combinational logic element for signal gating, enable control, and bus arbitration in automotive infotainment, ADAS sensor fusion, and powertrain subsystems where level-shifting and thermal robustness are required.

Technical Context

This device implements three independent 3-input AND gates using CMOS technology, supporting direct TTL-level interface and bidirectional voltage translation across 1.2 V–3.6 V domains. Each gate exhibits identical static and dynamic behavior, with input thresholds defined as VIH ≥ 0.65×VCC and VIL ≤ 0.35×VCC over full temperature range.

Propagation delay is tightly specified across supply voltages: 1.5 ns (min) to 7.2 ns (max) per gate at −40 °C to +125 °C, with output drive capability of ±24 mA at VCC = 3.0 V and VOL ≤ 0.55 V under load. Power dissipation capacitance CPD is 9.0 pF at VCC = 3.0–3.6 V, enabling accurate dynamic power estimation.

FAQ

Is the exposed thermal pad on the DHVQFN14 package required to be soldered?

No. Per datasheet Figure 6 note (1), the exposed pad has no electrical or mechanical requirement to be soldered. If soldered, it must remain floating or be connected to GND-never left as a floating conductor. Thermal performance improvement is marginal (<5 °C junction reduction) versus proper PCB copper pour under the package body.

Can 74LVC11BQ-Q100 operate reliably at 1.2 V supply while driving a 30 pF load?

Yes. At VCC = 1.2 V, propagation delay is specified at 14.0 ns (max) with 30 pF load and 1 kΩ termination (Table 8). Output drive remains functional with VOL ≤ 0.12 V and VOH ≥ 1.08 V, meeting LVC family logic thresholds for downstream 1.2 V receivers.

What is the maximum allowable input transition rate (dV/dt) for guaranteed timing performance?

The input transition rise/fall rate must not exceed 20 ns/V at VCC = 1.65–2.7 V and 10 ns/V at VCC = 2.7–3.6 V (Table 5). Exceeding these rates may cause increased propagation delay variation or metastability in edge-sensitive systems, though the device remains functional.

Does 74LVC11BQ-Q100 support hot insertion or live I/O biasing?

No. The device lacks explicit hot-swap protection circuitry. Input clamping current is limited to ±50 mA (Table 4), and VI absolute max is −0.5 V to +6.5 V. Live insertion into powered backplanes requires external series resistors and TVS diodes to limit transient current and voltage overshoot.
