Product details
Overview
74HC08DB,118 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 building block in digital control, interface buffering, and signal gating circuits.
For engineers reviewing the 74HC08DB,118 datasheet, 74HC08DB,118 pinout, 74HC08DB,118 application, or 74HC08DB,118 equivalent, key selection criteria include supply voltage range (2.0–6.0 V), propagation delay vs. VCC/CL, input threshold compatibility (CMOS), thermal rating (-40 °C to +125 °C), and SO14 package footprint compatibility with legacy 74-series layouts.
Technical Context
This device implements four independent 2-input AND gates using silicon-gate CMOS technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds referenced to VCC.
It operates across industrial and extended temperature ranges (-40 °C to +125 °C), complies with JEDEC JESD7A and JESD8C standards, and supports dynamic power calculation via CPD = 10 pF - enabling accurate estimation of switching power under known input/output toggle rates and load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate; each gate outputs HIGH only when both inputs are HIGH - enables basic enable, masking, and synchronization logic. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V microcontroller controlling 5 V peripherals). |
| Propagation Delay | 7 ns (typ.) at VCC = 6.0 V, CL = 50 pF - ensures timing-critical signal gating within sub-10 ns windows in high-speed digital control paths. |
| Output Drive | ±25 mA per output - sufficient to directly drive LEDs, small capacitive loads, or fan-out to ≥10 standard CMOS inputs. |
| Input Thresholds | VIH = 4.2 V (min), VIL = 1.8 V (max) at VCC = 6.0 V - provides >1.2 V noise margin for robust operation in electrically noisy environments. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded controllers. |
Pinout & Package
74HC08DB,118 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 1 is index-marked; pin 7 = GND; pin 14 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A of gates 1–4 | First input per AND gate; accepts CMOS-level signals; clamped to prevent overvoltage damage. |
| 1B, 2B, 3B, 4B | Data input B of gates 1–4 | Second input per AND gate; electrically identical to A inputs; enables dual-signal conjunction logic. |
| 1Y, 2Y, 3Y, 4Y | Data output of gates 1–4 | Active-HIGH AND result; capable of sourcing/sinking ±25 mA; rail-to-rail swing within VCC/GND limits. |
| 7 | GND | Primary ground reference; must be low-impedance connection to minimize switching noise coupling. |
| 14 | VCC | Positive supply rail; requires local 100 nF ceramic decoupling capacitor placed ≤5 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V operation - eliminates need for level shifters in multi-rail systems (e.g., 3.3 V MCU + 5 V sensor bus). |
| Input clamp diodes | Integrated protection enables safe interface to voltages > VCC using external current-limiting resistors - simplifies mixed-voltage signal routing. |
| High noise immunity | Typical noise margin >1.2 V at VCC = 6.0 V - reduces susceptibility to EMI-induced glitches in motor-drive or power-conversion control logic. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - ensures robustness against transient overcurrent events in industrial environments. |
| ESD protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 3 requirements without external protection components. |
Applications
| Industrial Control Logic | Digital Interface Buffering |
|---|---|
|
Use Scenario: Enabling discrete I/O signals in programmable logic controllers before feeding into microcontroller GPIOs. IC Role / Device Role / Timing Role: Signal gating element that validates dual conditions (e.g., "start button pressed AND safety interlock closed") before asserting control output. Use Value: Provides deterministic, low-latency Boolean evaluation with no internal state - avoids timing uncertainty introduced by software polling loops. |
Use Scenario: Isolating and synchronizing parallel data lines between a 5 V FPGA and a 3.3 V ARM processor. IC Role / Device Role / Timing Role: Level-adapted AND gate used as an active-enable buffer, where one input receives a direction-control signal and the other carries data. Use Value: Eliminates need for dedicated level translators by leveraging wide VCC range and CMOS input thresholds - reduces BOM count and PCB area. |
| Power Sequencing Control | LED Matrix Row Enable |
|
Use Scenario: Validating multiple power-good signals before releasing reset to a multi-rail SoC. IC Role / Device Role / Timing Role: Combinatorial arbiter ensuring all DC/DC converters have stabilized (PG = HIGH) prior to enabling downstream logic. Use Value: Guarantees strict power-up ordering with <10 ns propagation skew across all four gates - prevents metastability in clock domain crossings. |
Use Scenario: Driving row-select lines in a 4×N multiplexed LED display powered from 5 V. IC Role / Device Role / Timing Role: Row-enable gate where one input receives row address decode and the other receives global blanking pulse. Use Value: Delivers 25 mA sink current per output - directly drives up to 4 rows of common-anode LEDs without external transistors. |
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,118 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 5 V); otherwise identical pinout, timing, and packaging. | Better suited for interfacing with legacy 5 V TTL outputs without level shifting. | Select when driving from standard 5 V TTL sources; avoid if interfacing exclusively with modern CMOS (e.g., 3.3 V MCU). |
| SN74HC08DR | SO14 package, same logic function, but TI-specified VIH/VIL thresholds differ slightly (VIH = 3.15 V min at VCC = 4.5 V). | Marginally lower noise immunity at mid-rail VCC; identical timing performance at 5 V. | Valid drop-in for cost-sensitive designs where Nexperia qualification is not required; verify VIH/VIL margins in target VCC range. |
Compared with 74HCT08DB,118, the 74HC08DB,118 offers higher input noise margin in CMOS systems but lacks native TTL compatibility; versus SN74HC08DR, it delivers tighter VIH/VIL specs across full temperature range and superior latch-up immunity per JESD78 Class II.

FAQ
What is the maximum operating frequency of the 74HC08DB,118?
The 74HC08DB,118 does not specify a maximum clock frequency, as it is a combinational logic device without internal clocking. Its usable toggle rate depends on propagation delay and load capacitance: at VCC = 6.0 V and CL = 50 pF, tpd = 7 ns (typ.), supporting reliable operation up to ~50 MHz for repetitive enable/gating patterns with adequate setup/hold margins.
Can the 74HC08DB,118 be used with a 3.3 V supply?
Yes - the 74HC08DB,118 is fully specified from 2.0 V to 6.0 V. At VCC = 3.3 V, VIH = 2.1 V (min), VIL = 1.35 V (max), and VOH = 2.97 V (min) at IO = −4.0 mA, providing >1.0 V noise margin and compatible interfacing with 3.3 V LVTTL and most 3.3 V CMOS I/O standards.
Is the SO14 package of 74HC08DB,118 RoHS compliant and lead-free?
Yes - the 74HC08DB,118 in SOT108-1 (SO14) package is manufactured in compliance with EU RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination finish and halogen-free molding compound, as confirmed in Nexperia's official product change notices and material declarations.
Does the 74HC08DB,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 behavior, and potential ESD susceptibility. Nexperia recommends connecting unused inputs directly to VCC or GND; series resistors are unnecessary due to integrated input clamp diodes and low input leakage (<±0.1 μA).
