Product details
Overview
74AHCT2G241DC,125 from Nexperia is a dual 1-bit non-inverting buffer/line driver with independent 3-state outputs, TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), ±8 mA output drive, and operation from –40 °C to +125 °C in VSSOP8 package. It serves as a bidirectional bus interface or level translator in mixed-voltage digital systems.
For engineers reviewing the 74AHCT2G241DC,125 datasheet, 74AHCT2G241DC,125 pinout, 74AHCT2G241DC,125 application, or 74AHCT2G241DC,125 equivalent, key selection criteria include TTL-level input compatibility, dual independent 3-state control (1OE active LOW, 2OE active HIGH), 5.5 V absolute max supply rating, and VSSOP8 thermal performance (4.9 mW/K derating above 99 °C).
Technical Context
This device implements two independent CMOS buffer channels, each with separate enable logic: 1OE is active LOW (pulling LOW enables 1Y), while 2OE is active HIGH (driving HIGH enables 2Y). Both outputs enter high-impedance state when disabled, enabling bus sharing without contention.
Input overvoltage tolerance up to 5.5 V allows safe interfacing with higher-voltage logic even at lower VCC (e.g., 3.3 V supply with 5 V inputs). Propagation delays are tightly balanced - tpd ≤ 7.5 ns (CL = 50 pF, VCC = 5 V) for both channels - ensuring synchronous signal routing in timing-critical paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and robust noise margin |
| Input threshold (VIH/VIL) | 2.0 V / 0.8 V - matches legacy TTL logic families for seamless integration without level shifters |
| Output drive strength | ±8 mA - sufficient to drive 50 pF loads with <9.5 ns propagation delay at 5 V, supporting moderate fan-out |
| Operating temperature | –40 °C to +125 °C - qualified for industrial and extended-temperature embedded control applications |
| Power dissipation capacitance | 10 pF per buffer - enables accurate dynamic power estimation (PD = CPD × VCC² × fi) in high-frequency operation |
| ESD protection | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly |
| 3-state enable polarity | 1OE: active LOW; 2OE: active HIGH - supports flexible bus arbitration schemes with complementary control signals |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package; 8 leads; body width 2.3 mm; lead pitch 0.5 mm; pin 1 indicator below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW output enable for channel 1 - drives 1Y into high-Z when HIGH |
| 2 | VCC | Positive supply rail - must be decoupled locally to suppress switching noise |
| 3 | 1A | Inverting input for buffer 1 - passes signal to 1Y when 1OE is asserted |
| 4 | 2OE | Active-HIGH output enable for channel 2 - drives 2Y into high-Z when LOW |
| 5 | 2Y | Output of buffer 2 - reflects 2A when 2OE is HIGH; high-Z otherwise |
| 6 | 1Y | Output of buffer 1 - reflects 1A when 1OE is LOW; high-Z otherwise |
| 7 | GND | Ground reference - shared return path for all I/O and supply currents |
| 8 | 2A | Input for buffer 2 - non-inverting path to 2Y under 2OE control |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - eliminates need for external level translation when interfacing with legacy 5 V microcontrollers |
| Dual independent 3-state control | Separate 1OE (active LOW) and 2OE (active HIGH) pins - enables asymmetric bus arbitration and avoids simultaneous enable conflicts |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V regardless of VCC (down to 4.5 V) - prevents latch-up during hot-swap or mixed-rail power sequencing |
| Symmetrical output impedance | Matched rise/fall times and drive strength - reduces signal skew between rising and falling edges on same net |
| Industrial temperature range | Specified from –40 °C to +125 °C - supports deployment in motor drives, PLC I/O modules, and outdoor industrial gateways |
Applications
| Industrial Bus Interface | Microcontroller GPIO Expansion |

| Legacy System Upgrade | Test Equipment Signal Conditioning |
|
Use Scenario: Replacing obsolete 74LS241 in aging test fixtures where new boards must maintain pin-for-pin compatibility but require lower power and wider voltage tolerance. IC Role / Device Role: Drop-in functional replacement with identical pinout and TTL input compatibility, plus improved ESD robustness and thermal margin. Use Value: Extends product lifecycle without redesign - operates reliably at 125 °C ambient and withstands >2000 V HBM ESD events common in manufacturing environments. |
Use Scenario: Driving calibrated clock and trigger signals from a 5 V FPGA to multiple DUT inputs in automated test equipment, requiring precise edge timing and low crosstalk. IC Role / Device Role: Low-skew dual buffer with matched propagation delays (<1 ns channel-to-channel variation) and symmetrical output impedance.

FAQ
What is the difference between 74AHCT2G241DC and 74AHC2G241DC?
The 74AHCT2G241DC uses TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V), enabling direct connection to legacy 5 V TTL outputs. The 74AHC2G241DC uses CMOS thresholds (VIH ≥ 3.85 V), requiring compatible CMOS drivers. Both share identical pinout, 3-state behavior, and VSSOP8 package.
Can 74AHCT2G241DC,125 operate at 3.3 V supply?
No - the 74AHCT2G241DC is specified only for 4.5 V to 5.5 V supply. At 3.3 V, input thresholds fall outside guaranteed operation (VIH min = 2.0 V requires VCC ≥ 4.5 V per datasheet Table 6), risking unreliable logic recognition. Use 74AHC2G241DC or 74LVC2G241 for 3.3 V operation.
How does the dual enable architecture improve bus design?
Independent 1OE (active LOW) and 2OE (active HIGH) allow asymmetric control - e.g., one channel enabled during write cycles (1OE = LOW), the other during reads (2OE = HIGH), eliminating bus contention without external logic. This simplifies arbitration in half-duplex parallel interfaces.
Is the VSSOP8 package suitable for reflow soldering?
Yes - the SOT765-1 (VSSOP8) package is qualified for standard lead-free reflow profiles (J-STD-020). Peak temperature must not exceed 260 °C, and thermal profile must respect the 4.9 mW/K power derating slope above 99 °C to maintain reliability at full rated load.
