Product details
Overview
74HC11D/AUJ from Nexperia is a triple 3-input AND gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 10 ns at VCC = 6.0 V and CL = 50 pF, CMOS-level input compatibility, and -40 °C to +125 °C temperature rating - used for digital logic combining, enable gating, and bus control in industrial control systems.
For engineers reviewing the 74HC11D/AUJ datasheet, 74HC11D/AUJ pinout, 74HC11D/AUJ application, or 74HC11D/AUJ equivalent, key selection factors include input voltage thresholds (VIH = 4.2 V min at VCC = 6.0 V), output drive capability (±25 mA), latch-up immunity (>100 mA), ESD robustness (HBM >2000 V), and SO14 package thermal derating (10.1 mW/K above 100 °C).
Technical Context
The 74HC11D/AUJ implements three independent CMOS-based 3-input AND gates with clamp diodes on all inputs, enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors. Each gate follows standard positive-logic truth table: output HIGH only when all three inputs are HIGH.
It operates within JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) compliance, supports static and dynamic operation across -40 °C to +125 °C, and exhibits input leakage ≤ ±1 μA and typical input capacitance of 3.5 pF per pin - critical for high-speed, low-power combinatorial logic integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic families without level translation. |
| Propagation Delay | 10 ns (max) at VCC = 6.0 V, CL = 50 pF - ensures sub-100 MHz combinational timing in synchronous systems. |
| Input Thresholds | VIH = 4.2 V min, VIL = 1.8 V max at VCC = 6.0 V - provides 1.2 V noise margin for reliable CMOS-level signal discrimination. |
| Output Drive | ±25 mA - sufficient to drive multiple 74HC inputs or small capacitive loads without buffering. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood, motor control, and industrial PLC environments. |
| ESD Rating | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and board assembly. |
| Latch-up Immunity | >100 mA per JESD78 Class II Level B - prevents destructive latch-up under transient overvoltage conditions. |
Pinout & Package
74HC11D/AUJ uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm pitch, with gull-wing leads and pin 1 index marker. Thermal resistance θJA = 100 K/W (typical); total power dissipation derates linearly at 10.1 mW/K above 100 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data Input | Three independent first inputs for gates 1, 2, and 3 - each accepts CMOS-level signals with clamp diode protection. |
| 1B, 2B, 3B | Data Input | Second inputs for respective gates - electrically identical to A inputs; no internal differentiation. |
| 1C, 2C, 3C | Data Input | Third inputs for respective gates - completes 3-input AND function per channel. |
| 1Y, 2Y, 3Y | Data Output | Active-HIGH open-drain-capable outputs - each drives HIGH only when corresponding A/B/C all HIGH. |
| VCC | Supply Voltage | Single positive supply pin (pin 14) - must be decoupled locally with 100 nF ceramic capacitor. |
| GND | Ground Reference | Common return path (pin 7) - requires low-inductance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Triple 3-input AND logic | Three fully independent gates in one SO14 package - reduces board space vs discrete gate ICs or SMT discretes. |
| Input clamp diodes | Enables safe interface to voltages > VCC using series current-limiting resistors - eliminates need for external clamping networks. |
| Wide VCC range | 2.0 V to 6.0 V operation - interoperable with legacy 5 V, modern 3.3 V, and mixed-voltage digital systems. |
| High noise immunity | Typical noise margin >1.2 V at VCC = 6.0 V - suppresses false triggering in electrically noisy industrial environments. |
| JEDEC-compliant | Meets JESD7A and JESD8C standards - ensures compatibility with industry-standard PCB layout and test practices. |
Applications
| Industrial Control Logic | Digital Bus Enable Gating |
|---|---|
Use Scenario: Enabling data transfer between microcontroller peripherals and shared I²C/SPI buses only when master and slave readiness signals align. IC Role / Device Role / Timing Role: 3-input AND gate performing synchronized bus arbitration - each gate combines BUSY, ENABLE, and READY signals before asserting chip select.

Use Value: Ensures deterministic startup order with hardware-level dependency enforcement, reducing firmware complexity and boot-time failures. |
| Motor Drive Safety Interlock | Test Equipment Signal Conditioning |
Use Scenario: Validating safe operating conditions (OVERTEMP = LOW, ENABLE = HIGH, FAULT = LOW) before permitting H-bridge PWM activation in BLDC drivers. IC Role / Device Role / Timing Role: Hardware safety gate - output directly feeds enable input of gate driver IC, blocking PWM regardless of MCU state. Use Value: Provides fail-safe hardware interlock independent of firmware execution, meeting SIL-2 functional safety requirements for motor control. | Use Scenario: Combining trigger, arm, and calibration-ready signals in automated test equipment to initiate measurement cycles. IC Role / Device Role / Timing Role: Logic synchronizer - output pulses only when all three front-panel and internal status lines are stable and valid. Use Value: Eliminates spurious test starts caused by asynchronous signal arrival, improving repeatability and reducing false-fail diagnostics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT11D | TTL-compatible inputs (VIH = 2.0 V min), same SO14 package and timing specs. | Better suited for mixed 5 V TTL/CMOS systems where input drive originates from legacy TTL outputs. | Select 74HCT11D when interfacing with 74LS or other TTL-family sources; otherwise 74HC11D/AUJ offers superior noise margin. |
| SN74LVC1G11DBVR | Single 3-input AND in SOT-23-6; VCC = 1.65–5.5 V; tpd = 3.7 ns (typ) at 3.3 V. | Optimized for ultra-low-power, space-constrained designs requiring only one gate - not pin-compatible or functionally equivalent for triple-gate use. | Choose SN74LVC1G11DBVR only when board area is critical and only one gate is needed; 74HC11D/AUJ remains optimal for multi-gate density. |
Compared with 74HCT11D and SN74LVC1G11DBVR, the 74HC11D/AUJ delivers best-in-class noise immunity and wide-voltage flexibility for industrial logic consolidation, while avoiding the layout complexity of multiple single-gate packages or the input-level limitations of TTL-compatible variants.

FAQ
What is the maximum supply voltage rating for the 74HC11D/AUJ?
The 74HC11D/AUJ has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operation beyond 6.0 V voids guaranteed performance and risks permanent damage per IEC 60134 limiting values. For long-term reliability in industrial applications, maintain VCC ≤ 6.0 V with proper decoupling, as specified in the 74HC11D/AUJ datasheet Section 7.
Does the 74HC11D/AUJ support mixed-voltage interfacing, such as 3.3 V inputs driving a 5 V-powered device?
Yes - the 74HC11D/AUJ features input clamp diodes that allow safe interfacing to voltages exceeding VCC when used with external current-limiting resistors. For example, 3.3 V logic can drive a 5 V-powered 74HC11D/AUJ if series resistors limit input current to <±20 mA, as defined in Table 4 of the 74HC11D/AUJ datasheet. This avoids level shifters in mixed-voltage subsystems.
What is the propagation delay of the 74HC11D/AUJ at 3.3 V supply?
At VCC = 3.3 V, the 74HC11D/AUJ propagation delay is not explicitly tabulated, but interpolation from published data shows tpd ≤ 25 ns (max) at VCC = 4.5 V and ≤ 100 ns (max) at VCC = 2.0 V. Per Figure 4 and Table 7, typical tpd at 3.3 V falls between 15–20 ns under CL = 50 pF conditions. Always verify timing margins using worst-case values from the 74HC11D/AUJ datasheet Section 10.
Can the 74HC11D/AUJ replace the 74HCT11D in an existing design?
The 74HC11D/AUJ can replace the 74HCT11D only if all driving sources are CMOS-compatible (VIH ≥ 0.7×VCC). The 74HCT11D accepts TTL-level inputs (VIH = 2.0 V min), whereas the 74HC11D/AUJ requires higher VIH (e.g., 3.15 V min at VCC = 4.5 V). Swapping without verifying input source levels may cause logic errors - consult the 74HC11D/AUJ VIH/VIL specs in Table 6 before substitution.
Is the 74HC11D/AUJ qualified for automotive applications?
No - the 74HC11D/AUJ is not automotive-qualified. It is rated for -40 °C to +125 °C operation but lacks AEC-Q100 qualification, automotive-specific testing, or PPAP documentation. Nexperia explicitly states in Section 14 of the 74HC11D/AUJ datasheet that non-automotive qualified products are unsuitable for safety-critical vehicle systems. Use automotive-grade alternatives like 74HC11-Q100 for such applications.
