Product details
Overview
74HC11DB,118 from Nexperia is a triple 3-input AND gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, delivering propagation delays as low as 10 ns at VCC = 6.0 V and CL = 50 pF, with CMOS-level input compatibility, ±25 mA output drive, and guaranteed operation from −40 °C to +125 °C. It serves as a core combinational logic element in digital control, address decoding, and enable gating circuits.
For engineers reviewing the 74HC11DB,118 datasheet, 74HC11DB,118 pinout, 74HC11DB,118 application, or 74HC11DB,118 equivalent, this device is selected for high-noise-immunity, low-power 3-input logic gating in industrial microcontroller peripherals, serial interface handshaking, and power sequencing control where TTL-compatible variants are not required.
Technical Context
This device implements three independent AND functions using standard CMOS silicon, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds referenced to VCC, supporting robust logic level translation across mixed-voltage domains.
Its static characteristics include VIH ≥ 4.2 V and VIL ≤ 1.8 V at VCC = 6.0 V, while dynamic performance is characterized by tpd = 10–17 ns and tt = 6–13 ns under 50 pF load, with CPD = 18 pF enabling accurate dynamic power estimation via PD = CPD × VCC² × fi × N.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple independent 3-input AND gates; each outputs HIGH only when all three inputs are HIGH |
| Supply Voltage Range | 2.0 V to 6.0 V; supports direct interface with 3.3 V and 5 V systems without level shifters |
| Propagation Delay (tpd) | 10 ns (max) at VCC = 6.0 V, CL = 50 pF; enables reliable timing in sub-100 MHz synchronous logic paths |
| Output Drive | ±25 mA per output; sufficient to directly drive LED indicators, small MOSFET gates, or fan-out to ≥10 74HC inputs |
| Operating Temperature | −40 °C to +125 °C; qualified for extended industrial and under-hood automotive auxiliary applications |
| Input Clamp Diodes | Integrated on all inputs; permits safe overvoltage tolerance up to VCC + 0.5 V with external current limiting |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1, 2, 3 A-input) | Three dedicated first inputs per AND gate; electrically identical, CMOS-level compatible |
| 1B, 2B, 3B | Data input (Gate 1, 2, 3 B-input) | Three dedicated second inputs per AND gate; share same VIH/VIL thresholds and input capacitance (3.5 pF) |

| 1Y, 2Y, 3Y | Data output (Gate 1, 2, 3 output) | Push-pull CMOS outputs; VOH ≥ 5.48 V / VOL ≤ 0.26 V at VCC = 6.0 V and IO = ±5.2 mA |
| VCC | Positive supply | Single 2.0–6.0 V rail; powers all three gates; decoupling capacitor recommended within 10 mm |
| GND | Ground reference | 0 V return path for all inputs, outputs, and internal circuitry; must be low-impedance plane |

Use Scenario: Enabling discrete output modules in programmable logic controllers where multiple sensor conditions must be ANDed before activating a relay driver. IC Role / Device Role / Timing Role: Combinational logic gate performing real-time Boolean conjunction of three status bits (e.g., fault, ready, enable) to generate a single hardware-safe output strobe. Use Value: Eliminates need for firmware polling or additional MCU GPIOs; deterministic <17 ns response ensures cycle-accurate timing in 10 kHz scan loops. |
Use Scenario: Selecting memory-mapped peripheral registers in an 8-bit microcontroller system with limited address lines. IC Role / Device Role / Timing Role: Address decoder generating chip-select signals by ANDing upper address bits (A13–A15) to isolate specific 8 KB memory regions. Use Value: Reduces address decoding latency versus software-based selection; supports full-speed bus access without wait states at 20 MHz clock rates. |
| Power Sequencing Control | Serial Interface Handshaking |
|
Use Scenario: Coordinating startup order of multiple DC-DC converters in a multi-rail power supply for FPGA or SoC subsystems. IC Role / Device Role / Timing Role: Gate enabling the "enable" signal to a secondary regulator only after primary rail is stable, thermal OK, and reset released. Use Value: Ensures strict monotonic power-up sequence; eliminates reliance on slow RC timers or complex supervisor ICs. |
Use Scenario: Generating RTS/CTS flow-control signals in UART-to-RS-232 or UART-to-USB bridge designs with shared control lines. IC Role / Device Role / Timing Role: Logic combiner asserting hardware handshake only when both local buffer non-empty and remote ready flags are active.

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 |
|---|---|---|---|
| 74HCT11DB,118 | TTL-compatible inputs (VIH = 2.0 V min); otherwise identical pinout, timing, and packaging | Required when interfacing with legacy 5 V TTL outputs or microcontrollers lacking CMOS-level drive strength | Select when driving from 74LS/74F families or older MCUs with weak HIGH-level output; avoid if all sources are CMOS or 3.3 V. |
| SN74LVC1G11DRYR | Single 3-input AND in 6-pin X2SON; 1.65–5.5 V supply; 3.7 ns tpd at 3.3 V; no input clamps | Used for space-constrained point-of-load logic; lacks overvoltage tolerance and triple-gate integration | Choose for ultra-low-profile, high-speed single-gate use; not suitable as drop-in replacement due to pin count, lack of clamps, and no triple integration. |
Compared with 74HC11DB,118, the 74HCT11DB,118 offers identical timing and layout but accepts TTL input levels-critical for mixed-logic systems-while the SN74LVC1G11DRYR trades integration and ruggedness for speed and footprint reduction in isolated logic nodes.

FAQ
What is the maximum clock frequency supported by the 74HC11DB,118?
The 74HC11DB,118 is a combinational logic device-not a clocked sequential circuit-so it has no inherent clock frequency limit. Its usable toggle rate depends on propagation delay and system loading: with tpd = 17 ns max and CL = 50 pF, it reliably supports logic transitions up to ~30 MHz in well-designed PCB layouts with controlled impedance and proper decoupling.
Can 74HC11DB,118 safely interface with 12 V signals?
Yes-its inputs feature integrated clamp diodes. When a current-limiting resistor (e.g., 10 kΩ) is placed in series with a 12 V source, the diode conducts excess voltage to VCC or GND, limiting input voltage to VCC + 0.5 V or GND − 0.5 V. This avoids damage while preserving logic integrity, provided IIK remains within ±20 mA.
How does 74HC11DB,118 differ from 74HCT11DB,118 in practice?
The sole functional difference is input threshold compatibility: 74HC11DB,118 requires CMOS-level inputs (VIH ≥ 4.2 V at VCC = 6 V), while 74HCT11DB,118 accepts TTL-level inputs (VIH ≥ 2.0 V). All other parameters-including pinout, timing, supply range, and output drive-are identical. Selection hinges solely on upstream driver technology.
Is thermal derating required for continuous operation at +125 °C?
Yes-total power dissipation must be derated above 100 °C. For the SO14 (SOT108-1) package, Ptot decreases linearly by 10.1 mW/K. At +125 °C, maximum allowed Ptot drops to 474 mW (500 mW − 10.1 mW/K × 25 K). This corresponds to ~1.5 mA average ICC at VCC = 5 V, well within typical static current (<40 μA) but relevant under heavy capacitive switching.
