Product details
Overview
74HC08DB,112 from Nexperia is a quad 2-input AND gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, delivering propagation delay as low as 7 ns at VCC = 6.0 V and CL = 50 pF, with CMOS-level input compatibility and ±25 mA output drive capability. It serves as a fundamental combinational logic element in digital control, address decoding, and bus gating circuits.
For engineers reviewing the 74HC08DB,112 datasheet, 74HC08DB,112 pinout, 74HC08DB,112 application, or 74HC08DB,112 equivalent, key selection factors include its wide VCC range (2.0–6.0 V), guaranteed operation from –40 °C to +125 °C, input clamp diodes enabling overvoltage-tolerant interfacing, and SO14 package compatibility with legacy PCB footprints.
Technical Context
This device implements four independent 2-input AND gates using standard CMOS silicon technology, with inputs featuring integrated clamp diodes for robustness against transient overvoltage conditions. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds referenced to VCC, and supports rail-to-rail output swing under specified load conditions.
Its static and dynamic behavior is fully characterized across –40 °C to +125 °C, with propagation delays tightly specified at multiple VCC points (2.0 V, 4.5 V, 6.0 V) and defined test loads (CL = 50 pF). Input leakage remains below ±1 μA, and supply current stays under 40 μA at VCC = 6.0 V with all inputs static.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - provides four independent Boolean AND operations per package. |
| Supply Voltage Range | 2.0 V to 6.0 V - enables interoperability with 3.3 V and 5 V systems without level translation. |
| Propagation Delay (tpd) | 7 ns typical at VCC = 6.0 V, CL = 50 pF - ensures timing-critical path compatibility in medium-speed digital logic. |
| Output Drive | ±25 mA - sufficient to directly drive TTL loads or multiple CMOS inputs without buffering. |
| Operating Temperature | –40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications. |
| Input Clamp Diodes | Integrated - allows safe interface to signals exceeding VCC when used with current-limiting resistors. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds JEDEC JS-001/JS-002 Class 2/C3 requirements for board-level handling. |
Pinout & Package
74HC08DB,112 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each AND gate - accepts CMOS-level signals (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC). |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - electrically identical to A inputs; supports wired-OR via external pull-ups if needed. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Respective AND gate outputs - actively driven HIGH/LOW; no open-drain configuration. |
| 7 | GND | Ground reference (0 V) - must be connected to system common ground plane for stable operation. |
| 14 | VCC | Positive supply rail - decoupling capacitor (100 nF ceramic) recommended within 10 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0 V to 6.0 V - eliminates need for separate voltage domains in mixed-supply systems. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overcurrent events. |
| Input overvoltage tolerance | Clamp diodes enable safe interface to signals up to VCC + 0.5 V with current limiting - simplifies inter-IC signal routing. |
| Low static power | ICC ≤ 40 μA at VCC = 6.0 V, –40 °C to +125 °C - suitable for always-on logic in battery-backed subsystems. |
| Thermal performance | Ptot = 500 mW at Tamb ≤ 85 °C (SO14); derates linearly above 100 °C - supports high-density PCB layouts. |
Applications
| Industrial PLC I/O Expansion | Microcontroller Address Decoding |
|---|---|
|
Use Scenario: Expanding discrete input monitoring in programmable logic controllers using parallel GPIO banks. IC Role / Device Role / Timing Role: AND gate array performs enable masking of sensor status bits before latching into shift registers. Use Value: Enables real-time filtering of noisy field inputs without MCU intervention, reducing firmware overhead and jitter. |
Use Scenario: Selecting peripheral memory or peripheral devices on an 8-bit microcontroller bus with limited address lines. IC Role / Device Role / Timing Role: Combines upper address bits and chip-select strobes to generate precise decode windows for memory-mapped peripherals. Use Value: Provides deterministic, zero-software-latency peripheral selection with sub-10 ns setup/hold margins at 20 MHz bus speeds. |
| Automated Test Equipment (ATE) Signal Gating | Legacy Bus Interface Logic |
|
Use Scenario: Enabling stimulus delivery only during valid test cycles in boundary-scan or functional test fixtures. IC Role / Device Role / Timing Role: Gates clock or data signals based on synchronized control flags from FPGA sequencer. Use Value: Prevents spurious edge triggering on DUT pins during initialization or reset phases, improving test repeatability. |
Use Scenario: Interfacing modern microcontrollers to legacy parallel buses (e.g., ISA, PC/104) requiring active-low enable logic. IC Role / Device Role / Timing Role: Inverts and combines control signals (IOR#, IOW#, MEMR#) to generate device-specific chip enables. Use Value: Maintains strict timing alignment between control and data phases, avoiding bus contention in multi-master environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT08DB,112 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Required when interfacing with legacy 5 V TTL outputs lacking CMOS-level swing. | Select when driving from 74LS/74F series or older microcontrollers with weak HIGH drive. |
| SN74HC08DR | Same logic function and electrical specs, but TI SO14 package has different thermal pad layout and slightly tighter tpd min (6 ns @ 6 V). | Valid for drop-in replacement where TI qualification or sourcing preference applies. | Prefer when TI's enhanced ESD spec (HBM > 4000 V) or longer production lifecycle is required. |
Compared with 74HC08DB,112, the 74HCT08DB,112 offers guaranteed TTL input compatibility at the cost of reduced noise margin, while SN74HC08DR provides marginally faster minimum propagation delay and higher HBM ESD rating - both require validation of thermal pad soldering and PCB land pattern compatibility.

FAQ
Can 74HC08DB,112 operate reliably at 3.3 V?
Yes - it is fully specified from 2.0 V to 6.0 V, with VIH = 2.1 V min and VIL = 0.99 V max at VCC = 3.3 V, ensuring clean logic thresholds and 100% noise margin compliance. Propagation delay is 13 ns typical at 3.3 V with 50 pF load, making it suitable for 3.3 V FPGA or microcontroller glue logic.
Does 74HC08DB,112 have internal pull-up or pull-down resistors?
No - the inputs are high-impedance CMOS with no internal biasing resistors. External pull-up or pull-down resistors must be used if inputs require defined states during power-up, reset, or floating conditions. Input leakage remains below ±1 μA across temperature.
What is the maximum capacitive load this device can drive?
It is characterized up to 50 pF, but can reliably drive up to 75 pF with <10% increase in propagation delay and <5% rise/fall time degradation. For loads >75 pF, add a series resistor (22–47 Ω) near the output to dampen ringing and maintain signal integrity.
Is the exposed pad on the SO14 package electrically connected?
No - the SO14 (SOT108-1) package used in 74HC08DB,112 has no thermal pad or exposed die attach pad. The mechanical footprint matches standard SO14 land patterns; no special solder paste stencil or reflow profile adjustments are required beyond JEDEC MS-012 guidelines.
