Product details
Overview
74LVC11BQ from Nexperia is a triple 3-input AND gate logic IC operating across 1.2 V to 3.6 V supply, delivering propagation delays as low as 1.5 ns (VCC = 3.0–3.6 V), ±24 mA output drive capability, and full 5.5 V-tolerant inputs - deployed in high-density digital control planes of industrial PLC I/O modules, FPGA companion logic, and low-voltage sensor interface subsystems.
For engineers reviewing the 74LVC11BQ datasheet, 74LVC11BQ pinout, 74LVC11BQ application, or 74LVC11BQ equivalent, this page delivers verified pin mapping for DHVQFN14, JEDEC-compliant voltage thresholds (VIH/VIL), thermal derating data (9.6 mW/K above 98 °C), and direct TTL-level interoperability without level-shifting.
Technical Context
This device implements three independent 3-input AND gates in a single monolithic CMOS structure, with all inputs tolerant to 5.5 V regardless of VCC (1.2–3.6 V), enabling seamless interfacing between mixed-voltage domains. Each gate exhibits matched propagation delay symmetry (tPLH ≈ tPHL) and operates over -40 °C to +125 °C ambient.
It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and features ESD robustness per ANSI/ESDA/JEDEC JS-001 (HBM >2000 V) and JS-002 (CDM >1000 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - supports battery-powered and multi-rail systems without external regulators |
| Input Voltage Tolerance | Up to 5.5 V - enables direct connection to 5 V legacy logic or microcontroller GPIOs |
| Propagation Delay | 1.5 ns (min) at VCC = 3.0–3.6 V - ensures timing-critical combinational logic paths meet sub-2 ns budgets |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC/LVT inputs or small capacitive loads (<30 pF) |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-range embedded control |
| Power Dissipation | 500 mW max (Tamb ≤ 98 °C); derates 9.6 mW/K above - defines thermal limits for PCB layout in compact QFN footprints |
| Input Leakage | ±20 μA max at VCC = 3.6 V, VI = 5.5 V - negligible loading on high-impedance signal sources |
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 in quad arrangement with terminal 1 index area marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First AND gate input A - accepts 0–5.5 V signals independent of VCC |
| 2 | 1B | First AND gate input B - electrically identical to 1A; no internal series resistance |
| 3 | 1C | First AND gate input C - shares same VIH/VIL thresholds and ESD protection as 1A/1B |
| 4 | 2A | Second AND gate input A - isolated from Gate 1; no crosstalk in static or dynamic operation |
| 5 | 2B | Second AND gate input B - matches propagation delay and drive strength of Gate 1 |
| 6 | 1Y | First AND gate output Y - drives load referenced to GND; VOL ≤ 0.55 V @ 24 mA |
| 7 | GND | Ground reference - mandatory 0 V return path for all I/O and supply current |
| 8 | 2Y | Second AND gate output Y - specified VOH ≥ 2.2 V @ -24 mA (VCC = 3.0 V) |
| 9 | 3A | Third AND gate input A - fully identical in electrical behavior to 1A and 2A |
| 10 | 3B | Third AND gate input B - supports same input transition rate (10 ns/V at VCC ≥ 2.7 V) |
| 11 | 3C | Third AND gate input C - validated for simultaneous switching with other inputs |
| 12 | 3Y | Third AND gate output Y - meets same AC/DC specs as 1Y and 2Y |
| 13 | 2C | Second AND gate input C - pin position confirmed per Fig. 6 (SOT762-1 top view) |
| 14 | VCC | Positive supply - must be decoupled locally; total ICC ≤ 100 mA under worst-case switching |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.2–3.6 V) | Enables direct integration into 1.8 V microcontroller peripherals and 3.3 V FPGA I/O banks without level shifters |

| HBM/CDM ESD rating | Meets industrial handling requirements (HBM >2000 V, CDM >1000 V) without additional board-level protection |
| Thermal-enhanced DHVQFN | 0.85 mm profile and exposed pad support higher sustained switching rates than SO14 or TSSOP variants |
Applications
| Industrial PLC I/O Expansion | FPGA Configuration Logic |
|---|---|
|
Use Scenario: Combining three discrete status signals (e.g., limit switch, fault flag, enable) to generate a single hardware interlock output. IC Role / Device Role / Timing Role: Combinational logic gate performing synchronous 3-input AND function with sub-2 ns propagation to meet real-time safety response deadlines. Use Value: Reduces BOM count vs. discrete transistor logic; eliminates timing skew between parallel paths in safety-critical shutdown chains. |
Use Scenario: Validating configuration handshake between FPGA and external memory or peripheral before releasing reset. IC Role / Device Role / Timing Role: Glue logic element ensuring all three configuration readiness signals are asserted before enabling FPGA core clocks. Use Value: Provides deterministic, zero-latency assertion of CONFIG_DONE enable without consuming FPGA LUT resources or introducing routing delay uncertainty. |
| Sensor Signal Conditioning Hub | Low-Voltage Power Sequencing |
|
Use Scenario: Aggregating valid-data flags from three analog sensor ADCs (temperature, pressure, humidity) to gate system wake-up interrupt. IC Role / Device Role / Timing Role: Input synchronizer and combiner - accepts asynchronous 5 V sensor flags and outputs clean 3.3 V logic to MCU interrupt pin. Use Value: Enables 5 V sensor compatibility while maintaining 3.3 V system logic levels; avoids false triggers from partial signal transitions. |
Use Scenario: Enabling 1.2 V core rail only after both 3.3 V I/O and 1.8 V PLL rails stabilize, using dedicated power-good signals. IC Role / Device Role / Timing Role: Power sequencing arbiter - asserts "core enable" only when all three upstream rails meet regulation criteria. Use Value: Prevents CPU lockup due to out-of-spec voltage sequencing; replaces discrete diode-OR + RC networks with deterministic logic thresholding. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC11APWR | TSSOP14 package (SOT402-1); 4.4 mm body width; 7.3 mW/K thermal derating above 81 °C | Better suited for manual assembly or lower-density boards where QFN reflow is impractical | Select when board assembly process lacks QFN-capable reflow profiling or optical inspection capability |
| 74LVC11D,118 | SO14 package (SOT108-1); 3.9 mm body; 10.1 mW/K derating above 100 °C; longer lead form factor | Preferred for through-hole prototyping, legacy repair, or environments requiring mechanical robustness over thermal density | Choose when vibration resistance, hand-soldering, or socket-based validation is required |
Compared with SN74LVC11APWR and 74LVC11D,118, the 74LVC11BQ offers superior thermal performance (9.6 mW/K derating starting at 98 °C) and smallest footprint (2.5 × 3.0 mm), making it optimal for space-constrained, high-reliability industrial control modules where thermal headroom and board area are critical constraints.

FAQ
Can 74LVC11BQ operate reliably at 1.2 V supply while driving a 15 pF load?
Yes. At VCC = 1.2 V, the device guarantees tpd ≤ 14.0 ns (−40 °C to +85 °C) and VOL ≤ 0.12 V @ 4 mA, meeting timing and noise margin requirements for low-power sensor interface logic. Static current remains below 10 μA, preserving battery life in always-on monitoring nodes.
Is the exposed thermal pad on the DHVQFN14 package required to be soldered to ground?
No. Per Figure 6 and datasheet note, the thermal pad has no electrical or mechanical requirement to be soldered. If soldered, it must remain floating or connect to GND - no internal connection exists, and improper grounding introduces no functional risk but may affect thermal performance.
Does 74LVC11BQ support hot insertion or live swapping in backplane applications?
No. The device lacks hot-swap protection circuitry (e.g., power-up sequencing, bus-hold, or Ioff). Applying VCC before GND or inserting while powered risks violating absolute maximum ratings (e.g., VI < 0 V), potentially damaging inputs. Use only in fixed, pre-powered systems.
How does the 5.5 V input tolerance interact with VCC = 1.65 V operation?
Inputs remain fully functional and protected at 5.5 V even when VCC = 1.65 V, thanks to integrated clamping diodes and oxide-thickness design. VIH is defined at 0.65×VCC (≈1.07 V), ensuring reliable HIGH detection despite the 5.5 V swing - no external resistors needed.
