Product details
Overview
74AHCT2G241GD,125 from Nexperia is a dual 1-bit non-inverting 3-state buffer/line driver with independent active-LOW and active-HIGH output enables (1OE, 2OE), 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 an XSON8 package. It serves as a voltage-level translator and bus interface in mixed-voltage digital systems.
For engineers reviewing the 74AHCT2G241GD,125 datasheet, 74AHCT2G241GD,125 pinout, 74AHCT2G241GD,125 application, or 74AHCT2G241GD,125 equivalent, key selection criteria include TTL input compatibility, dual independent 3-state control, overvoltage-tolerant inputs up to 5.5 V, low propagation delay (≤7.5 ns at VCC = 5 V, CL = 50 pF), and industrial temperature range support.
Technical Context
The device implements two independent buffer channels, each with separate enable logic: 1OE is active-LOW (output enabled when LOW), while 2OE is active-HIGH (output enabled when HIGH). This asymmetric enable architecture allows flexible bus arbitration-e.g., one channel can be held active while the other is dynamically gated without shared control timing constraints.
Inputs tolerate up to 5.5 V regardless of VCC (2.0–5.5 V), enabling safe interfacing between 3.3 V logic domains and 5 V peripherals. Output drive strength is symmetrical (±8 mA), with VOH ≥ 3.7 V and VOL ≤ 0.55 V under full load, ensuring robust noise margins in noisy industrial environments.
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 tolerance for supply ripple. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - Guarantees reliable recognition of legacy TTL logic levels. |
| Output Drive | ±8 mA - Supports direct connection to multiple CMOS/TTL loads without external buffering. |
| Propagation Delay | ≤7.5 ns (VCC = 5 V, CL = 50 pF) - Enables use in high-speed data paths up to ~100 MHz toggle rate. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives. |
| Input Overvoltage Tolerance | 5.5 V absolute max - Allows safe interfacing with 5 V signals even when powered from 3.3 V. |
| Power Dissipation | 250 mW max (Tamb ≤ 99 °C) - Sufficient thermal headroom for continuous operation in compact PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT2G241DC,125 | VSSOP8 package (2.3 mm width); 0.65 mm pitch; higher thermal resistance (RθJA = 205 K/W vs. XSON8's 160 K/W). | Better suited for manual soldering or prototyping due to larger lead pitch and visibility. | Select when board assembly uses fine-pitch reflow but requires easier visual inspection or hand rework. |
| SN74LVC2G241DCKR | CMOS input thresholds (VIH = 70% VCC); lower VCC range (1.65–5.5 V); identical XSON8 footprint. | Preferred for ultra-low-power battery applications where static current <1 μA is required below 2.5 V. | Select when operating below 3 V or requiring tighter input threshold tracking across supply variation. |
Compared with 74AHCT2G241DC,125, the GD variant offers superior thermal performance in space-constrained layouts; compared with SN74LVC2G241DCKR, it delivers guaranteed TTL compatibility at 5 V but consumes slightly higher quiescent current above 4.5 V.

FAQ
What is the maximum clock frequency supported by the 74AHCT2G241GD,125?
The device does not operate as a clocked element but as a combinational buffer. Its usable toggle rate is determined by propagation delay and load capacitance. With tPD ≤ 7.5 ns (VCC = 5 V, CL = 50 pF), it supports clean signal transmission up to approximately 100 MHz for short traces with minimal capacitive loading. For sustained high-frequency operation, layout must minimize trace inductance and maintain tight VCC/GND decoupling.
Can the 74AHCT2G241GD,125 be used with a 3.3 V supply?
No - the 74AHCT2G241GD,125 is specified only for VCC = 4.5 V to 5.5 V. Its TTL input thresholds (VIH = 2.0 V min) are optimized for 5 V systems. Using 3.3 V violates recommended operating conditions and risks unreliable HIGH-level detection. For 3.3 V operation, select the 74AHC2G241GD,125 (CMOS-input version) or SN74LVC2G241.
How are the two output enables (1OE and 2OE) intended to be used together?
1OE (active-LOW) and 2OE (active-HIGH) provide complementary control logic to avoid bus contention in multi-master systems. For example, 1OE can be tied to a system reset (LOW during reset), keeping Channel 1 active, while 2OE is driven by a processor GPIO to selectively gate Channel 2 - enabling independent timing control without shared enable logic delays or race conditions.
Is the thermal pad on the XSON8 package electrically connected?
Yes - the exposed thermal pad on the 74AHCT2G241GD,125 (XSON8/SOT833-1) is internally connected to GND. It must be soldered to a PCB copper pour tied to the main ground plane to achieve specified thermal performance (RθJA = 160 K/W) and ensure reliable operation at +125 °C ambient. Omitting pad connection degrades power handling by >30%.
