Product details
Overview
74HC11DB,112 from Nexperia is a triple 3-input AND gate in SSOP14 (SOT337-1) package, operating from 2.0 V to 6.0 V supply, delivering CMOS-level input compatibility, propagation delay as low as 12 ns at VCC = 4.5 V, and guaranteed operation from -40 °C to +125 °C - used for digital logic combining, enable gating, and bus control in industrial microcontroller peripherals.
For engineers reviewing the 74HC11DB,112 datasheet, 74HC11DB,112 pinout, 74HC11DB,112 application, or 74HC11DB,112 equivalent, key selection criteria include input voltage threshold (VIH = 3.15 V min at VCC = 4.5 V), output drive strength (IOH = -4.0 mA, IOL = 4.0 mA), power dissipation capacitance (CPD = 18 pF), and SSOP14 thermal derating behavior above 81 °C.
Technical Context
This device implements three independent 3-input AND functions with clamp diodes on all inputs, enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits identical static and dynamic behavior across temperature and supply voltage ranges.
It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), supports HBM ESD > 2000 V and CDM > 1000 V, and meets latch-up immunity per JESD78 Class II Level B (>100 mA). Input thresholds are CMOS-compatible, not TTL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay | 12 ns typ (VCC = 4.5 V, CL = 50 pF) - enables reliable timing in sub-40 MHz synchronous logic paths. |
| Output Drive | ±4.0 mA - sufficient to drive one 74HC input or two 74LS inputs under worst-case VCC and temperature. |
| Input Threshold | VIH = 3.15 V min (VCC = 4.5 V); VIL = 1.35 V max - ensures noise margin > 1.1 V in 5 V systems. |
| Power Dissipation Cap | CPD = 18 pF - determines dynamic power: PD = 18 × VCC² × fIN × 3 + Σ(CL × VCC² × fOUT). |
| Operating Temp | -40 °C to +125 °C - qualified for extended industrial and under-hood automotive auxiliary circuits. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - reduces need for external protection in board-level ESD zones. |
Pinout & Package
74HC11DB,112 uses the SSOP14 (SOT337-1) package: plastic shrink small outline, 14 leads, body width 5.3 mm, 0.65 mm lead pitch, and exposed pad optional per variant - optimized for high-density PCB layouts with improved thermal conduction vs SO14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1–3 A) | First input of each 3-input AND gate; accepts CMOS-level signals up to VCC + 0.5 V with clamping. |
| 1B, 2B, 3B | Data input (Gate 1–3 B) | Second input per gate; electrically identical to A/C pins; no internal ordering dependency. |
| 1C, 2C, 3C | Data input (Gate 1–3 C) | Third input per gate; all nine inputs share identical VIH/VIL and leakage specs (±0.1 μA max). |
| 1Y, 2Y, 3Y | Data output (Gate 1–3 Y) | Active-high AND result; rail-to-rail swing (VOL ≤ 0.26 V, VOH ≥ 3.98 V at 4.5 V/–4 mA/+4 mA). |
| VCC | Positive supply | Single 2.0–6.0 V rail; decoupling capacitor required within 10 mm due to fast edge rates (tt ≤ 15 ns). |
| GND | Ground reference | 0 V return for all inputs/outputs; must connect to low-impedance plane to maintain noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0–6.0 V operation enables reuse across 3.3 V MCU I/O banks and legacy 5 V backplanes. |
| Input clamp diodes | Allow safe overvoltage tolerance (e.g., 12 V sensor inputs) when paired with series current-limiting resistors. |
| High noise immunity | Typical noise margin > 1.1 V at 5 V supply ensures robustness against crosstalk in mixed-signal PCBs. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - eliminates risk of destructive latch-up during transient faults. |
| Low ICC quiescent | Max 40 μA at 125 °C - supports always-on monitoring circuits without significant battery drain. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
|
Use Scenario: Enabling discrete sensor inputs (e.g., door open/closed, seatbelt buckle) before routing to MCU GPIO. IC Role / Device Role / Timing Role: Logic-level AND combiner that validates multiple conditions (e.g., ignition ON AND door open) before asserting interrupt. Use Value: Reduces MCU firmware complexity by offloading boolean decision logic; operates reliably at 125 °C ambient near engine bay electronics. |
Use Scenario: Gating CAN transceiver standby mode based on ignition state and diagnostic request presence. IC Role / Device Role / Timing Role: Three-input enable gate ensuring transceiver powers only when ignition is active, bus is idle, and no diagnostics pending. Use Value: Low ICC (≤40 μA) extends sleep-mode battery life; SSOP14 footprint saves space in compact BCM modules. |
| Medical Infusion Pump UI Logic | Test Equipment Signal Conditioning |
|
Use Scenario: Validating simultaneous press of "Start" + "Confirm" + "Safety Lock" buttons before motor activation. IC Role / Device Role / Timing Role: Hardware interlock gate preventing single-point failure from initiating therapy delivery. Use Value: Fail-safe hardware AND function with <15 ns propagation ensures deterministic response; certified for extended temp range (-40 to +125 °C). |
Use Scenario: Synchronizing trigger signals from multiple instruments (oscilloscope, DMM, signal generator) before data capture. IC Role / Device Role / Timing Role: Edge-aligned AND gate generating composite trigger only when all sources assert valid strobes. Use Value: Matched tPHL/tPLH (<2 ns skew between gates) ensures precise multi-instrument coordination without FPGA overhead. |
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 |
|---|---|---|---|
| 74HC11D,112 | SO14 (SOT108-1) package; 3.9 mm body width; Ptot derates at 10.1 mW/K above 100 °C. | Better thermal mass for moderate-power continuous operation; less dense layout than SSOP. | Select for cost-sensitive industrial boards where reflow profile favors SOIC and thermal load is steady-state. |
| SN74HC11PWR | TSSOP14 (SOT402-1); 4.4 mm body; Ptot derates at 7.3 mW/K above 81 °C; TI branding. | Higher pin density than SO14 but lower thermal efficiency than SSOP14 above 81 °C. | Choose when sourcing from TI-authorized channels is mandatory; verify VIL/VIH match for 3.3 V logic interfacing. |
Compared with 74HC11DB,112, the SO14 variant offers superior thermal stability at high ambient temperatures, while the TSSOP14 alternative trades some thermal margin for broader distributor availability - SSOP14 remains optimal for space-constrained, high-reliability industrial designs requiring extended temperature compliance.

FAQ
What is the maximum clock frequency supported by 74HC11DB,112?
The 74HC11DB,112 is a combinational logic gate, not a clocked device, so it has no defined clock frequency. Its usable toggle rate depends on propagation delay and system loading: with tpd = 12 ns (typ) and CL = 50 pF, maximum reliable switching is ~30 MHz in clean 5 V systems. Real-world limits are set by board parasitics and fanout.
Can 74HC11DB,112 interface directly with 3.3 V microcontrollers?
Yes - at VCC = 3.3 V, VIH(min) = 2.1 V and VIL(max) = 1.2 V per datasheet Table 6, providing >1.1 V noise margin. Outputs swing rail-to-rail (VOH ≥ 3.15 V, VOL ≤ 0.26 V), making it compatible with standard 3.3 V CMOS inputs without level shifting.
Does 74HC11DB,112 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied HIGH or LOW to prevent floating states that increase ICC and cause erratic outputs. The device has no internal pull-ups; leaving inputs unconnected risks oscillation, excess power draw, and EMI. Tie to VCC or GND via short trace or 0 Ω resistor.
Is 74HC11DB,112 qualified for automotive applications?
No - although rated for -40 °C to +125 °C, this part is not AEC-Q200 qualified and lacks automotive-specific reliability testing (e.g., HTOL, temperature cycling, board-level vibration). It may be used in non-safety-critical automotive subsystems at designer's risk, but not for ADAS, powertrain, or airbag systems.
