Product details

Overview

74AHC2G241DC,125 from Nexperia is a dual 3-state buffer/line driver in VSSOP8 (SOT765-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V and CMOS-level input thresholds. It supports independent 3-state control via active-low 1OE and active-high 2OE, enabling flexible bus interfacing in mixed-voltage digital systems such as industrial I/O expansion and FPGA peripheral buffering.

For engineers reviewing the 74AHC2G241DC,125 datasheet, 74AHC2G241DC,125 pinout, 74AHC2G241DC,125 application, or 74AHC2G241DC,125 equivalent, key selection criteria include its dual independent enable logic, 5.5 V overvoltage tolerance on inputs, propagation delay ≤7.5 ns at 5 V/50 pF, symmetrical output drive (±8 mA), and operation across –40 °C to +125 °C.

Technical Context

This device implements two independent non-inverting buffers, each with dedicated 3-state output control: 1OE (active LOW) and 2OE (active HIGH). Its input structure accepts voltages up to 5.5 V regardless of VCC, enabling level translation between 3.3 V and 5 V domains without external circuitry.

Each buffer exhibits matched propagation delays (tpd ≤7.5 ns @ VCC = 5 V, CL = 50 pF), symmetrical VOH/VOL (≤0.36 V low, ≥3.94 V high @ IO = ±8 mA), and low ICC (≤40 μA max @ VCC = 5.5 V), supporting low-power, noise-immune signal routing in space-constrained PCB layouts.

Key Specifications

Pinout & Package

VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 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 enable for first buffer - Pull LOW to enable 1Y; HIGH places 1Y in high-impedance state.
2	VCC	Positive supply rail - Must be decoupled locally with 100 nF ceramic capacitor near pin 2.
3	1A	Data input for first buffer - Accepts overvoltage-tolerant signals up to 5.5 V independent of VCC.
4	2OE	Active-HIGH enable for second buffer - Drive HIGH to enable 2Y; LOW disables 2Y to high-impedance.
5	2Y	Data output for second buffer - Non-inverting output with ±8 mA drive capability and 3-state control.
6	1Y	Data output for first buffer - Matches 2Y timing and drive strength; enables dual-channel synchronized buffering.
7	GND	Ground reference - Connect directly to low-impedance PCB ground plane to minimize noise coupling.
8	2A	Data input for second buffer - Electrically identical to 1A; supports independent or mirrored input sourcing.

Key Features

Feature	Design Value
Dual independent 3-state control	1OE (active LOW) and 2OE (active HIGH) allow asymmetric enable sequencing - e.g., staggered bus release or priority-based output arbitration.
Overvoltage-tolerant inputs	Inputs withstand 5.5 V regardless of VCC (2.0–5.5 V), eliminating external clamping diodes when interfacing 5 V sensors to 3.3 V MCUs.
Symmetrical output impedance	Matched rise/fall times and VOH/VOL ensure clean signal edges and minimal duty-cycle distortion in clock or data lines.
Low dynamic power dissipation	CPD = 10 pF per buffer - Enables high-speed operation with predictable dynamic power: PD ≈ 10 × VCC² × fi (μW) at 1 MHz.
Extended temperature qualification	Specified from –40 °C to +125 °C - Validated for continuous operation in automotive engine control units and industrial motor drives.

Applications

Industrial I/O Expansion

FPGA Peripheral Buffering

Use Scenario: Isolating and driving 16-bit parallel I/O from a microcontroller to external relays, ADCs, and display drivers in a programmable logic controller.

IC Role / Device Role / Timing Role: Dual buffer provides direction-controlled signal conditioning and load isolation; 3-state outputs prevent bus contention during configuration changes.

Use Value: Eliminates need for discrete MOSFET switches or additional logic gates while maintaining <8 ns propagation delay and ±8 mA drive per channel.

Use Scenario: Interfacing a Xilinx Artix-7 FPGA's bank-restricted I/O (3.3 V) to legacy 5 V peripherals including EEPROMs and UART transceivers.

IC Role / Device Role / Timing Role: Level-translating buffer with overvoltage-tolerant inputs - accepts 5 V signals safely while powered from 3.3 V, preserving timing integrity.

Use Value: Achieves voltage-domain bridging without external resistors or active translators, reducing BOM count and layout area by 30% vs. discrete solutions.

Automotive Sensor Interface

High-Density Data Acquisition

Use Scenario: Conditioning analog sensor outputs (e.g., pressure, temperature) before digitization in an automotive cabin controller operating at 125 °C ambient.

IC Role / Device Role / Timing Role: Signal repeater and noise filter - buffers weak sensor signals while rejecting common-mode noise via matched output impedance.

Use Value: Maintains signal fidelity across full temperature range with <0.55 V VOL and >3.7 V VOH at 125 °C, ensuring robust ADC sampling margins.

Use Scenario: Multiplexing 8-channel analog front-end data paths onto a shared SPI bus in a medical diagnostic device requiring sub-10 ns timing alignment.

IC Role / Device Role / Timing Role: Synchronized dual buffer - enables simultaneous enable/disable of two signal paths with matched tpd and tdis (<9.5 ns variation).

Use Value: Guarantees deterministic inter-channel skew <1 ns, critical for time-of-flight or phase-sensitive measurements.

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	TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) vs. AHC's CMOS thresholds (VIH = 3.85 V @ 5.5 V).	Required when interfacing with legacy 5 V TTL outputs; not suitable for pure CMOS systems with marginal high-level noise margins.	Select AHCT version only if driving source is TTL-compliant; otherwise AHC ensures superior noise immunity in modern CMOS designs.
SN74LVC2G241DCTR	Lower VCC range (1.65–5.5 V), higher ICC (≤10 μA typ), and slightly longer tpd (≤9.5 ns @ 5 V/50 pF).	Better suited for ultra-low-power battery-operated devices; less ideal for high-speed industrial buses requiring sub-8 ns timing.	Prefer LVC for portable equipment with tight current budgets; choose AHC for speed-critical, thermally demanding applications.

Compared with 74AHCT2G241DC,125, the AHC variant offers tighter noise margins and higher VIH, while SN74LVC2G241DCTR trades 1.5 ns speed for broader low-voltage operation - making 74AHC2G241DC,125 optimal for high-reliability, high-speed 3.3 V/5 V mixed-signal interfaces.

FAQ

What is the maximum input voltage the 74AHC2G241DC,125 can tolerate?

The 74AHC2G241DC,125 accepts input voltages up to 5.5 V regardless of VCC level, as confirmed in Section 8 (Limiting Values) and Section 9 (Recommended Operating Conditions) of the Nexperia datasheet Rev. 5. This overvoltage tolerance applies to all input pins (1A, 2A, 1OE, 2OE) and enables safe interfacing with 5 V sources while operating from 3.3 V or 2.5 V supplies.

Can 1OE and 2OE be tied together for single-enable operation?

Yes - 1OE (active LOW) and 2OE (active HIGH) can be connected through an inverter or level-shifter to create a unified enable signal, but direct tying is electrically invalid due to opposite polarity. For true single-enable behavior, use an external inverter (e.g., 74AHC1G04) between one enable input and the other, or select a single-enable variant like 74AHC244.

Does the 74AHC2G241DC,125 support hot insertion?

No - the device lacks explicit hot-swap or live-insertion qualification. While its overvoltage-tolerant inputs improve robustness during power-rail sequencing, the datasheet does not specify Ioff (off-state current) limits under partial power conditions, nor does it guarantee latch-up immunity during uncontrolled voltage ramp-up. Use external hot-swap controllers for backplane or modular system applications.

What is the thermal derating behavior above 99 °C ambient?

For the VSSOP8 (SOT765-1) package, total power dissipation (Ptot) derates linearly at 4.9 mW/K above 99 °C, as specified in Table 5 (Limiting Values). At 125 °C ambient, Ptot is reduced to 126.5 mW (250 mW − 4.9 mW/K × 26 K), requiring careful thermal design - e.g., ≥2 cm² copper pour under the exposed pad - to maintain junction temperature within safe limits.
