Product details
Overview
74HCT2G08DC,125 from Nexperia is a dual 2-input AND gate in VSSOP8 package, operating at 4.5 V to 5.5 V supply with TTL-compatible inputs and CMOS outputs. It delivers propagation delay of 14 ns (typ) at 5 V, supports -40 °C to +125 °C ambient range, and features input clamp diodes enabling safe interfacing to voltages exceeding VCC - used in digital logic control subsystems of industrial PLC I/O modules.
For engineers reviewing the 74HCT2G08DC,125 datasheet, 74HCT2G08DC,125 pinout, 74HCT2G08DC,125 application, or 74HCT2G08DC,125 equivalent, key selection criteria include TTL-level input compatibility, 125 °C extended temperature rating, VSSOP8 footprint constraints, and guaranteed 4 mA output drive at VOH ≥ 3.7 V and VOL ≤ 0.4 V.
Technical Context
This device implements two independent AND logic functions with fully buffered inputs and outputs. Each gate accepts TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) and drives CMOS-compatible loads with rail-to-rail swing under 4 mA load.
Input clamp diodes allow external current-limiting resistors for overvoltage-tolerant interfacing, while static characteristics guarantee VIH/VIL margins across full temperature range and dynamic performance remains stable up to 125 °C with tpd ≤ 36 ns (max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input AND gates with truth table L/L→L, L/H→L, H/L→L, H/H→H |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL and mixed-voltage 5 V/3.3 V systems |
| Propagation Delay | 14 ns (typ), 36 ns (max) at VCC = 4.5 V, CL = 15 pF - enables reliable operation in sub-30 MHz synchronous logic paths |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive standard 50 pF loads or fan-out to ≥10 74HCT inputs |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive control units and industrial motor drives |
| Input Clamp Diodes | Integrated on all inputs - permits safe interface to signals up to VCC + 0.5 V using series resistors |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 for board-level robustness |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; lead pitch 0.5 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First gate input A - accepts TTL-level signals; clamped to GND/VCC |
| 2 | 1B | First gate input B - identical electrical behavior to Pin 1 |
| 3 | 1Y | First gate output Y - CMOS rail-to-rail swing, 4 mA sink/source capability |
| 4 | GND | Ground reference - must be low-impedance connection to system 0 V plane |
| 5 | 2Y | Second gate output Y - electrically isolated from 1Y; shares same VCC/GND |
| 6 | 2B | Second gate input B - functionally identical to Pin 2 |
| 7 | 2A | Second gate input A - functionally identical to Pin 1 |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V - eliminates level-shifting when interfacing legacy 5 V microcontrollers |
| Extended temperature range | -40 °C to +125 °C operation - supports deployment in engine control units and power converter feedback loops |
| Low dynamic power | CPD = 10 pF - limits switching power to < 250 μW at 1 MHz with 5 V supply and 15 pF load |
| Input clamp diodes | Enables direct connection to 12 V sensor signals via 10 kΩ series resistor - avoids external protection components |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 5 V - suppresses false triggering in electrically noisy factory environments |
Applications
| Industrial Sensor Interface | Motor Control Logic |
|---|---|
Use Scenario: Combining limit switch and emergency stop signals before enabling motor driver enable line. IC Role / Device Role / Timing Role: Dual AND gate performing safety-critical signal arbitration with deterministic 36 ns max propagation delay.

Use Scenario: Synchronizing trigger pulses from multiple instruments before routing to DUT input. IC Role / Device Role / Timing Role: Pulse coincidence detection using two independent AND gates with matched propagation paths. Use Value: Achieves < 1 ns skew between channels due to monolithic die construction - superior to discrete gate ICs. |
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 |
|---|---|---|---|
| SN74LVC2G08DCUR | 3.3 V only (1.65–5.5 V), lower VIL (0.7 V), higher speed (tPHL = 3.2 ns typ) | Optimized for 3.3 V systems; not rated for 125 °C operation | Select when interfacing 3.3 V FPGAs and thermal budget allows ≤ 85 °C ambient |
| 74HC2G08DC,125 | CMOS input thresholds (VIH = 3.15 V min at 4.5 V), wider VCC range (2–6 V), same package | Requires level translation for TTL sources; better noise margin in high-noise 5 V systems | Choose for pure CMOS designs or where input noise immunity outweighs TTL compatibility needs |
Compared with SN74LVC2G08DCUR and 74HC2G08DC,125, the 74HCT2G08DC,125 uniquely balances TTL input compatibility, 125 °C rating, and VSSOP8 footprint - making it optimal for retrofitting legacy 5 V industrial controllers without redesigning voltage rails or thermal management.

FAQ
What is the maximum recommended supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 4.5 V to 5.5 V per JEDEC JESD7A. Exceeding 5.5 V risks violating static and dynamic specifications, including VOH degradation and increased ICC beyond 20 μA typical.
Can 74HCT2G08DC,125 safely interface with 12 V sensors?
Yes - its integrated input clamp diodes allow connection to 12 V signals when used with a series current-limiting resistor (e.g., 10 kΩ), limiting IIK to ≤ ±20 mA. This avoids external protection diodes while maintaining logic integrity across the full -40 °C to +125 °C range.
Is the VSSOP8 package RoHS and REACH compliant?
Yes - Nexperia confirms SOT765-1 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound. Full compliance documentation is available via Nexperia's product change notifications portal.
Does propagation delay vary significantly between the two gates on the same die?
No - matching between gates is inherent to monolithic construction. Measured tPHL/tPLH variation is < 0.5 ns across temperature and voltage, verified per Nexperia characterization data. This ensures consistent timing in dual-path logic such as pulse synchronization or redundant signal validation.
