Product details
Overview
74HCT11DB,112 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 = 5.0 V), 14-pin SO14 (SOT108-1) package, propagation delay of 16–36 ns (VCC = 4.5–5.5 V, CL = 50 pF), and operating temperature range of −40 °C to +125 °C. It performs basic combinational logic in digital control subsystems, bus gating, and enable signal conditioning.
For engineers reviewing the 74HCT11DB,112 datasheet, 74HCT11DB,112 pinout, 74HCT11DB,112 application, or 74HCT11DB,112 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed timing specs under industrial temperature conditions, and real-world substitution guidance for legacy 74-series logic upgrades.
Technical Context
The 74HCT11DB,112 implements three independent AND gates using CMOS technology with TTL-level input compatibility-ensuring seamless interfacing with legacy 5 V bipolar logic families without level-shifting. 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 static behavior is defined by guaranteed VIH/VIL thresholds aligned to JEDEC JESD7A, while dynamic performance is characterized at CL = 50 pF with tPD specified across −40 °C to +125 °C. The device exhibits low ICC (≤40 μA at VCC = 5.5 V, full temperature range) and high noise immunity due to hysteresis-free but robust input threshold margins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate - enables parallel Boolean conjunction of three signals per channel |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V TTL systems; not rated below 4.5 V |
| Propagation Delay (tPD) | 16–36 ns @ VCC = 4.5–5.5 V, CL = 50 pF - determines maximum clock/data rate in synchronous gating paths |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V @ VCC = 5.0 V - ensures reliable recognition of TTL logic levels |
| Output Drive | ±4.0 mA @ VOH/VOL - sufficient to drive 10 LS-TTL loads or moderate capacitive loads (<50 pF) |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood automotive-adjacent environments |
| Power Dissipation | CPD = 20 pF - enables accurate dynamic power estimation: PD = CPD × VCC² × fi × N |
Pinout & Package
74HCT11DB,112 is housed in a 14-lead plastic small outline package (SO14), SOT108-1, with 3.9 mm body width and 1.27 mm lead pitch. Pin 1 is marked by a beveled corner or notch; the package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input A for gates 1/2/3 | First input per AND gate; accepts TTL-level HIGH/LOW signals |

| 1C, 2C, 3C | Data input C for gates 1/2/3 | Third input per AND gate; all inputs include clamp diodes for overvoltage protection |
| 1Y, 2Y, 3Y | Data output Y for gates 1/2/3 | Active-high AND result; drives downstream CMOS/TTL loads up to ±4 mA |
| VCC | Positive supply | Must be decoupled locally; powers internal logic and output buffers |
| GND | Ground reference | Return path for all inputs, outputs, and supply current; requires low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables direct interface with 74LS, 74F, and microcontroller GPIOs without level shifters |
| Clamp diode protected inputs | Allows safe use with input voltages exceeding VCC when series current-limiting resistors are applied |
| Wide industrial temperature range | Validated operation from −40 °C to +125 °C supports deployment in harsh thermal environments |
| Low quiescent current | ICC ≤ 40 μA across full temperature range minimizes standby power in battery-backed systems |
| JEDEC-compliant packaging | SOT108-1 (SO14) footprint matches industry-standard PCB footprints and reflow profiles |
Applications
| Industrial PLC I/O Expansion | Microcontroller Bus Gating |
|---|---|
|
Use Scenario: Enabling/disabling data lines between CPU and peripheral modules based on address decode. IC Role / Device Role / Timing Role: Triple AND gate acting as synchronous bus enable controller; each gate selects one 3-bit data segment. Use Value: Eliminates need for discrete transistors or larger CPLDs; propagation delay <25 ns ensures no timing violation in 20 MHz bus cycles. |
Use Scenario: Conditional activation of sensor read/write strobes in multi-sensor monitoring systems. IC Role / Device Role / Timing Role: Logic gate combining interrupt request, ready flag, and chip select to generate precise enable pulses. Use Value: Reduces firmware overhead by offloading combinatorial logic; TTL input compatibility avoids external level translation. |
| Legacy System Logic Retrofit | Power Sequencing Control |
|
Use Scenario: Replacing obsolete 74LS11 in aging test equipment where board space and pinout must be preserved. IC Role / Device Role / Timing Role: Drop-in functional replacement with identical pinout and improved noise immunity. Use Value: Maintains system timing integrity while reducing power consumption and improving ESD robustness (HBM >2000 V). |
Use Scenario: Generating delayed enable signals for DC-DC converters based on multiple voltage-rail OK flags. IC Role / Device Role / Timing Role: Three-input AND gate verifying presence of VCC_3V3, VCC_5V, and RESET# before releasing POWER_EN. Use Value: Provides deterministic power-up sequencing without software intervention; clamp diodes tolerate minor rail overshoot during startup. |
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 |
|---|---|---|---|
| 74HCT11D,118 | Same die, identical electrical specs, but in SO14 package with different reel coding (118 vs 112); same pinout and thermal profile | No functional difference; differs only in packaging logistics and traceability marking | Select when requiring alternate tape-and-reel configuration or distributor-specific stock codes |
| SN74HCT11DR | TI variant with tighter tPD min (12 ns vs 16 ns), higher ICC max (100 μA), and −40 °C to +85 °C rating only | Limited temperature range reduces suitability for extended industrial deployments; faster min delay may affect setup/hold margins | Prefer only if operating exclusively within 0–85 °C and requiring marginally better worst-case speed |
Compared with 74HCT11DB,112, the 74HCT11D,118 offers identical functionality with logistical differentiation, while SN74HCT11DR trades extended temperature capability for slightly improved speed and higher quiescent current-making the Nexperia part optimal for thermally demanding, long-lifecycle industrial designs.

FAQ
Is 74HCT11DB,112 pin-compatible with 74HC11 variants?
Yes-74HCT11DB,112 shares identical SO14 pinout (SOT108-1) with 74HC11D and other 74HCT11 variants. However, input thresholds differ: 74HCT11 accepts TTL levels (VIH ≥ 2.0 V), while 74HC11 requires CMOS levels (VIH ≥ 3.15 V at VCC = 4.5 V). Swapping them without verifying driving source logic levels may cause functional failure.
Can 74HCT11DB,112 operate at 3.3 V supply?
No-74HCT11DB,112 is not characterized or guaranteed for operation below 4.5 V. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive are specified only across 4.5–5.5 V. For 3.3 V systems, consider 74LVC11 or 74AUP1G08-based solutions instead.
What is the maximum capacitive load this device can drive reliably?
The 74HCT11DB,112 is tested and specified with CL = 50 pF, and its transition time (tt) remains within 7–22 ns across temperature. Driving >100 pF may increase propagation delay unpredictably and risk signal integrity issues; for heavier loads, add a buffer stage or use a higher-drive logic family like 74ACT.
Does this part include ESD protection on all pins?
Yes-74HCT11DB,112 features integrated ESD protection on all I/O pins: Human Body Model (HBM) >2000 V and Charged Device Model (CDM) >1000 V, per ANSI/ESDA/JEDEC JS-001 and JS-002 standards. Input clamp diodes further enhance robustness against transient overvoltage events during handling or system operation.
