Product details
Overview
74AHC2G08DC,125 from Nexperia is a dual 2-input AND gate logic IC in VSSOP8 (SOT765-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, CMOS-level input thresholds, and propagation delay as low as 3.2 ns (typ.) at 5 V/15 pF - used for level translation and signal gating in mixed-voltage digital interfaces.
For engineers reviewing the 74AHC2G08DC,125 datasheet, 74AHC2G08DC,125 pinout, 74AHC2G08DC,125 application, or 74AHC2G08DC,125 equivalent, key selection criteria include input voltage tolerance, propagation delay vs. load capacitance, output drive capability (±8 mA), operating temperature range (–40 °C to +125 °C), and compatibility with 3.3 V / 5 V logic domains.
Technical Context
This device implements two independent AND gates in a single compact VSSOP8 package, with symmetrical output impedance and balanced tPLH/tPHL delays ensuring clean signal timing across both channels. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic and 5 V systems without external level shifters.
The 74AHC2G08DC operates under CMOS input logic levels (VIH ≥ 3.85 V at VCC = 5.5 V; VIL ≤ 1.65 V), delivers VOH ≥ 3.94 V and VOL ≤ 0.36 V at IO = ±8 mA, and maintains static current below 40 μA over full temperature range - supporting low-power, noise-immune digital control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input AND gate - provides two independent Boolean AND operations per package. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports interoperability across 2.5 V, 3.3 V, and 5 V digital systems. |
| Propagation Delay | 3.2 ns (typ.) at VCC = 5.0 V, CL = 15 pF - enables high-speed signal gating in timing-critical paths. |
| Input Voltage Tolerance | Inputs rated to 5.5 V independent of VCC - allows safe connection to higher-voltage buses without clamping diodes. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive standard CMOS loads and moderate PCB trace capacitance. |
| Operating Temperature | –40 °C to +125 °C - qualified for industrial and extended-temperature embedded control applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - enhances robustness during board handling and system integration. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located on lower left corner below marking code A08.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First gate input A - accepts CMOS-level signals; tolerant to 5.5 V regardless of VCC. |
| 2 | 1B | First gate input B - paired with 1A to generate 1Y = 1A ∧ 1B. |
| 3 | 2Y | Second gate output - active-high AND result; drives downstream logic or interface lines. |
| 4 | GND | Ground reference - must be low-impedance return path for all internal switching currents. |
| 5 | 2A | Second gate input A - electrically isolated from first gate; shares same supply domain. |
| 6 | 2B | Second gate input B - complements 2A to produce 2Y output per truth table. |
| 7 | 1Y | First gate output - synchronous with 1A/1B transitions; matches 2Y timing within 0.3 ns skew. |
| 8 | VCC | Positive supply - powers both gates; decoupling capacitor (100 nF) recommended near pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (<0.5 ns difference), reducing signal distortion in differential-sensitive paths. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V on any input while VCC = 2.0–5.5 V - eliminates need for external level translators in mixed-rail designs. |
| Wide temperature operation | Specified from –40 °C to +125 °C - supports deployment in automotive engine compartments and industrial motor drives. |
| Low dynamic power dissipation | CPD = 17 pF per buffer - limits switching power to <1.5 mW at 10 MHz, 3.3 V, enabling battery-powered logic functions. |
| High noise immunity | VIH/VIL margins exceed 1.2 V at VCC = 3.3 V - rejects EMI-induced glitches on control lines in noisy environments. |
Applications
| Industrial PLC I/O Expansion | USB-C Power Delivery Control |

Use Scenario: Enabling/disabling isolated digital outputs in modular I/O racks using 3.3 V microcontroller signals while interfacing with 5 V field sensors. IC Role / Device Role / Timing Role: Dual AND gate performs synchronized enable gating for two independent output channels, with sub-4 ns propagation ensuring deterministic response to safety-critical commands. Use Value: Input overvoltage tolerance eliminates level-shifter ICs, reducing BOM count and PCB area by 30% per channel versus discrete solutions. |
Use Scenario: Validating CC line handshake sequences in USB-C PD controllers where 3.3 V host logic must conditionally assert 5 V-compatible control pulses. IC Role / Device Role / Timing Role: Acts as voltage-domain bridge and logic enabler - one gate validates VBUS presence, the other gates PD policy engine signals before transmission. Use Value: Guaranteed 5.5 V input tolerance prevents latch-up when CC line transients exceed 3.3 V rail, improving system reliability during hot-plug events. |

Use Scenario: Combining door lock status and ignition state signals to enable window motor drivers only when vehicle is in park and doors are unlocked. IC Role / Device Role / Timing Role: Dual AND gate implements fail-safe interlock logic - both inputs must be HIGH to assert motor enable, with propagation delay tightly bounded to prevent race conditions. Use Value: –40 °C to +125 °C rating ensures functional correctness across cabin temperature extremes, eliminating derating calculations required with commercial-grade logic. |
Use Scenario: Gating alarm trigger signals from pressure and flow sensors before forwarding to microcontroller interrupt pins in Class II medical devices. IC Role / Device Role / Timing Role: Provides hardware-level signal arbitration - only validated sensor pairs activate alarm path, preventing false positives from transient noise spikes. Use Value: Low ICC (<40 μA max) and high noise immunity reduce risk of spurious interrupts, supporting IEC 62304 Class C software safety requirements without additional filtering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT2G08DC,125 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher propagation delay (3.6 ns typ. at 5 V/15 pF). | Better suited for legacy 5 V TTL systems where input threshold matching is critical. | Select when interfacing with older microcontrollers or FPGAs with TTL-output buffers. |
| SN74LVC2G08DCUR | Lower VCC range (1.65–5.5 V), higher drive (±32 mA), but no overvoltage-tolerant inputs (max VI = VCC + 0.5 V). | Preferred in ultra-low-voltage (1.8 V) FPGA I/O banks, but requires external clamping for >VCC inputs. | Choose for 1.8 V/2.5 V systems where overvoltage tolerance is unnecessary and higher sink/source is needed. |
Compared with 74AHCT2G08DC,125, the 74AHC2G08DC,125 offers tighter input thresholds and faster timing in CMOS domains; versus SN74LVC2G08DCUR, it trades off absolute drive strength for guaranteed 5.5 V input tolerance - making it superior for mixed-rail signal conditioning where voltage translation integrity is non-negotiable.

FAQ
Can 74AHC2G08DC,125 operate reliably at 2.0 V supply?
Yes. The device is fully specified down to 2.0 V supply, with guaranteed VIH ≥ 1.5 V and VIL ≤ 0.5 V at that rail, and propagation delay ≤ 12.0 ns (max) at CL = 50 pF. Static current remains below 10 μA, supporting battery-backed applications.
What is the maximum capacitive load this device can drive?
The 74AHC2G08DC,125 is characterized up to 50 pF load capacitance, with typical propagation delay of 4.6 ns at VCC = 4.5 V. Driving >50 pF increases delay nonlinearly and may cause marginal timing; for >100 pF, add a buffer stage or reduce trace length.
Does this part support hot-swap or live-insertion?
No. While inputs tolerate 5.5 V statically, the device lacks powered-off protection (Ioff). Applying signals to inputs or outputs while VCC = 0 V may cause back-powering or latch-up; always power VCC before applying logic signals.
How does the overvoltage tolerance work internally?
Input pins integrate dedicated clamp structures that shunt excess voltage (>VCC + 0.5 V) to VCC or GND via controlled diodes, limiting current to safe levels (<20 mA per pin). This allows direct connection to 5 V buses even when VCC = 3.3 V, without external components.
