Product details
Overview
74AHCT2G241DP,125 from Nexperia is a dual 3-state buffer/line driver in TSSOP8 (SOT505-2) package, operating from 4.5 V to 5.5 V supply, featuring TTL-compatible inputs, symmetrical output impedance, and overvoltage-tolerant inputs up to 5.5 V. It supports mixed-voltage interfacing between 3.3 V and 5 V domains in industrial control backplanes and microcontroller I/O expansion.
For engineers reviewing the 74AHCT2G241DP,125 datasheet, 74AHCT2G241DP,125 pinout, 74AHCT2G241DP,125 application, or 74AHCT2G241DP,125 equivalent, key selection criteria include TTL-level input thresholds (VIH = 2.0 V min), 3-state enable polarity asymmetry (1OE active LOW, 2OE active HIGH), propagation delay ≤7.5 ns at 5 V/50 pF, and operation across –40 °C to +125 °C.
Technical Context
This device implements two independent non-inverting buffers, each with dedicated 3-state control: 1OE (active LOW) governs 1Y, while 2OE (active HIGH) governs 2Y. Input logic levels conform to TTL thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), enabling direct interface with legacy 5 V logic families without level shifters.
Its overvoltage-tolerant inputs (rated to 5.5 V regardless of VCC) allow safe operation when driven by higher-voltage signals-e.g., 5 V outputs driving a 3.3 V-powered system-without external clamping. Output drive strength is ±8 mA at VOH/VOL specifications, with balanced tPLH/tPHL ensuring minimal skew in timing-critical data paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V logic rails and tolerates nominal 5 V ±10 % variation. |
| Input Threshold (VIH) | 2.0 V min - Guarantees reliable recognition of TTL HIGH from legacy 5 V sources. |
| Propagation Delay | ≤7.5 ns at VCC = 5 V, CL = 50 pF - Supports >100 MHz data rates in short trace applications. |
| Output Drive | ±8 mA - Sustains signal integrity across typical PCB traces and moderate fan-out (e.g., 10 LSTTL loads). |
| Operating Temperature | –40 °C to +125 °C - Validated for under-hood automotive modules and industrial motor drives. |
| Input Overvoltage Tolerance | 5.5 V absolute max - Enables safe interfacing with 5 V peripherals even when VCC = 3.3 V. |
| 3-State Enable Logic | 1OE active LOW, 2OE active HIGH - Allows independent, polarity-matched control of two data paths in bus arbitration schemes. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW enable for output 1Y - Pull LOW to assert 1Y; HIGH places 1Y in high-impedance state. |
| 2 | VCC | Positive supply rail - Must be decoupled locally; supports 4.5–5.5 V operation. |
| 3 | 1A | Data input for buffer 1 - Non-inverting; accepts TTL or overvoltage signals up to 5.5 V. |
| 4 | 2OE | Active-HIGH enable for output 2Y - Drive HIGH to assert 2Y; LOW disables 2Y. |
| 5 | 2Y | Data output for buffer 2 - Drives load with ±8 mA capability; high-Z when 2OE = LOW. |
| 6 | 1Y | Data output for buffer 1 - Matches 2Y drive strength; high-Z when 1OE = HIGH. |
| 7 | GND | Ground reference - Return path for all currents; must connect to low-impedance system ground plane. |
| 8 | 2A | Data input for buffer 2 - Electrically identical to 1A; supports independent dual-channel buffering. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | VIH = 2.0 V min, VIL = 0.8 V max - Eliminates need for external level translators when interfacing with 5 V microcontrollers or FPGAs. |
| Asymmetric 3-state enables | 1OE active LOW, 2OE active HIGH - Simplifies bus arbitration logic by matching common control signal polarities (e.g., /CS vs OE). |
| Overvoltage-tolerant inputs | Withstand 5.5 V regardless of VCC - Enables robust mixed-supply designs where 5 V sensors drive 3.3 V logic sections. |
| Symmetrical output impedance | Matched rise/fall times (tPLH ≈ tPHL) - Reduces signal distortion and jitter in high-speed digital lines. |
| High noise immunity | Typical VIH–VIL margin >1.2 V at 5 V - Resists EMI-induced false triggering in electrically noisy industrial environments. |
Applications
| Industrial PLC Backplane Interface | Microcontroller I/O Expansion |

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 |
|---|---|---|---|
| SN74LVC2G241DBVR | CMOS inputs (VIH = 0.7×VCC), 1.65–5.5 V supply, 1OE/2OE both active LOW | Better suited for ultra-low-voltage systems (1.8 V), less tolerant of 5 V inputs without external clamping | Select when operating below 3 V or requiring symmetric enable polarity; avoid if interfacing unclamped 5 V sources. |
| 74AHC2G241DP,125 | CMOS inputs (VIH = 0.5×VCC at 3.3 V), 2.0–5.5 V supply, same pinout and 3-state logic | Lower static current (<1 μA), wider VCC range, but lacks TTL input compatibility | Choose for battery-powered systems needing lowest ICC or mixed 2.5/3.3/5 V operation; not drop-in for TTL-driven designs. |
Compared with SN74LVC2G241DBVR and 74AHC2G241DP,125, the 74AHCT2G241DP,125 uniquely provides TTL-level input compatibility at 5 V while retaining overvoltage tolerance-making it the only option among the three that safely interfaces legacy 5 V logic without redesigning input conditioning networks.

FAQ
What is the maximum clock frequency supported by 74AHCT2G241DP,125?
The device does not operate as a clocked element but as a combinational buffer. Its 7.5 ns max propagation delay at 5 V/50 pF supports data rates up to ~133 MHz in point-to-point configurations. System-level timing depends on trace capacitance, load, and board layout-not internal clocking.
Can 74AHCT2G241DP,125 be used with a 3.3 V supply?
No. The 74AHCT variant requires VCC ≥ 4.5 V to meet TTL input threshold specifications (VIH ≥ 2.0 V). At 3.3 V, VIH would fall below 2.0 V, risking unreliable HIGH detection. Use 74AHC2G241DP,125 instead for 3.3 V operation with CMOS inputs.
Why do 1OE and 2OE have opposite active polarities?
This design allows flexible bus control: 1OE (active LOW) aligns with common chip-select (/CS) signals, while 2OE (active HIGH) matches enable (/EN) or output-enable (OE) signals in legacy systems. It simplifies logic synthesis when one channel must follow inverted control and the other non-inverted.
Is thermal derating required for continuous operation at 125 °C?
Yes. For the TSSOP8 (SOT505-2) package, total power dissipation derates linearly at 4.6 mW/K above 96 °C. At 125 °C, Ptot is reduced to approximately 115 mW from the 250 mW rating at 25 °C-requiring careful thermal design and current limiting in high-ambient applications.
