Product details
Overview
74HCT11DB,118 from Nexperia is a triple 3-input AND gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 14-pin SO14 (SOT108-1) package, propagation delay of 16–36 ns (VCC = 4.5–5.5 V), and operating temperature range of −40 °C to +125 °C. It performs combinational logic in digital control subsystems, bus gating, and enable signal conditioning.
For engineers reviewing the 74HCT11DB,118 datasheet, 74HCT11DB,118 pinout, 74HCT11DB,118 application, or 74HCT11DB,118 equivalent, key selection criteria include input compatibility with legacy 5 V TTL systems, guaranteed noise immunity over industrial temperature, SO14 package footprint for through-hole or surface-mount PCB integration, and static drive capability (±4 mA output).
Technical Context
The 74HCT11DB,118 implements three independent AND gates using CMOS technology with TTL-level input circuitry-ensuring direct interfacing with standard 5 V TTL outputs without level shifters. Each gate accepts three inputs (A, B, C) and produces one active-high output (Y), with all inputs featuring integrated clamp diodes for overvoltage tolerance when used with current-limiting resistors.
Its logic behavior follows strict Boolean AND truth table: output is HIGH only when all three inputs are HIGH; otherwise, output is LOW. The device operates across 4.5–5.5 V supply, supports static fan-out of ≥10 LS-TTL loads, and maintains defined VIH/VIL thresholds across full temperature and voltage ranges per JEDEC JESD7A and JESD8C standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate - three independent combinatorial logic units, each requiring all three inputs HIGH to assert HIGH output |

| VCC | Positive supply | Single 4.5–5.5 V supply connection; powers all three gates; decoupling capacitor required near pin |
| GND | Ground reference | 0 V return path for all logic and power currents; must be low-impedance and tied to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply enables plug-in replacement of 74LS11 in legacy designs |
| Industrial temperature range | −40 °C to +125 °C operation verified per JEDEC JESD22-A108, supporting engine control, motor drives, and factory automation |
| Low dynamic power | CPD = 20 pF enables sub-mW dynamic power at 1 MHz switching (PD ≈ CPD × VCC² × fi), reducing thermal load in dense logic arrays |
| Clamp diode inputs | Integrated input diodes allow safe interface to voltages up to VCC + 0.5 V using series current-limiting resistors, simplifying mixed-voltage interconnect |
| High noise immunity | Typical noise margin > 0.4 V at VCC = 5 V ensures stable operation in electrically noisy environments like industrial motor controls |
Applications
| Bus Enable Control | Digital Signal Conditioning |
|---|---|
Use Scenario: Enabling data transfer between microcontroller peripherals and shared memory or I/O buses. IC Role / Device Role / Timing Role: Acts as a 3-input bus gate: address decode bits and chip-select signal jointly enable bus access only when all conditions are met. Use Value: Prevents bus contention by ensuring exclusive access windows; eliminates need for discrete diode-OR or additional logic stages. | Use Scenario: Filtering spurious pulses on reset or interrupt lines before they trigger MCU events. IC Role / Device Role / Timing Role: Configured as a 3-input coincidence detector: only sustained HIGH states on all three inputs produce a valid output pulse. Use Value: Adds hardware debouncing and noise rejection without software overhead or RC timing components. |
| Power Sequencing Logic | Legacy System Interface |
Use Scenario: Controlling activation of downstream DC-DC converters or analog front-ends based on multiple readiness signals. IC Role / Device Role / Timing Role: Combines "VDD_OK", "CLK_READY", and "CONFIG_DONE" signals to generate a synchronized power-enable strobe. Use Value: Ensures strict sequencing compliance before enabling sensitive subsystems, improving system reliability and startup repeatability. | Use Scenario: Interfacing modern microcontrollers with legacy 5 V TTL peripheral boards lacking level-shifting circuitry. IC Role / Device Role / Timing Role: Provides bidirectional logic-level translation: accepts TTL outputs directly and drives TTL inputs with full current compliance. Use Value: Eliminates need for dedicated level translators or resistor networks, reducing BOM count and layout complexity. |
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 |
|---|---|---|---|
| SN74HCT11DR | TI SO14 variant; identical VIH/VIL, tpd = 17–37 ns; same 4.5–5.5 V range; slightly higher ICC (max 40 μA vs. 20 μA) | Qualified to AEC-Q100 Grade 3; suitable for automotive cabin electronics where extended temp is required | Select if automotive qualification or TI ecosystem alignment is prioritized over Nexperia's lower quiescent current |
| 74HCT11PW,118 | Nexperia TSSOP14 (SOT402-1); identical logic and electrical specs; smaller footprint (4.4 mm width); 7.3 mW/K derating above 81 °C vs. 10.1 mW/K for SO14 | Better suited for space-constrained PCBs; thermal performance differs due to package geometry and PCB copper exposure | Select for high-density layouts where SO14 footprint is prohibitive; verify thermal relief and reflow profile for TSSOP |
Compared with SN74HCT11DR and 74HCT11PW,118, the 74HCT11DB,118 offers lowest quiescent supply current (20 μA max), optimized SO14 thermal derating for high-ambient applications, and direct drop-in compatibility with legacy 74HCT11-based schematics without footprint or timing recalculations.

FAQ
Is 74HCT11DB,118 pin-compatible with 74HC11DB,118?
Yes - both share identical SO14 (SOT108-1) pinout and terminal assignment. However, 74HCT11DB,118 uses TTL-compatible input thresholds (VIH = 2.0 V min), whereas 74HC11DB,118 requires CMOS-level inputs (VIH = 3.15 V min at VCC = 4.5 V). Swapping requires verifying source driver compatibility.
What is the maximum recommended operating frequency for 74HCT11DB,118?
The device does not specify a maximum clock frequency, as it is combinational logic. Its usable toggle rate depends on propagation delay and load: with tpd = 16–36 ns and CL = 50 pF, practical edge rates are ≤20 MHz for clean signal integrity. For synchronous use, ensure setup/hold times of upstream drivers exceed tpd + margin.
Can 74HCT11DB,118 operate at 3.3 V supply?
No - the 74HCT11DB,118 is specified only for 4.5–5.5 V operation. At 3.3 V, input thresholds become undefined and output drive degrades significantly. For 3.3 V systems, use 74LVC11 or 74AUP1G08 variants instead.
Does 74HCT11DB,118 require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be terminated to VCC or GND to prevent floating nodes, which cause increased ICC, erratic output, and EMI. Tie unused A/B/C inputs directly to VCC (for LOW-effective disable) or GND (for HIGH-effective disable), not left open.
