NXP Semiconductors 74AHC2G241GD,125

Overview

74AHC2G241GD,125 from Nexperia is a dual 1-bit non-inverting 3-state buffer/line driver in XSON8 (SOT833-1) package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V and independent active-low (1OE) and active-high (2OE) output enables. It serves as a level-translating bus interface in mixed-voltage digital systems such as industrial I/O modules and sensor signal conditioning circuits.

For engineers reviewing the 74AHC2G241GD,125 datasheet, 74AHC2G241GD,125 pinout, 74AHC2G241GD,125 application, or 74AHC2G241GD,125 equivalent, key selection criteria include input voltage tolerance, dual independent 3-state control logic, propagation delay under 7 ns at 5 V/50 pF, CMOS-level compatibility, and operation across –40 °C to +125 °C.

Technical Context

This device implements two independent CMOS buffer channels, each with separate enable inputs: 1OE (active LOW) and 2OE (active HIGH), allowing asymmetric control of output states. Each channel provides non-inverting data path (1A→1Y, 2A→2Y) with high-impedance OFF-state when enabled is inactive.

Input overvoltage tolerance (up to 5.5 V regardless of VCC) enables safe interfacing between 3.3 V logic and 5 V buses without external level shifters. Static and dynamic characteristics are fully specified across –40 °C to +125 °C, supporting automotive-grade ambient operation in non-safety-critical control subsystems.

FAQ

Can 74AHC2G241GD,125 operate with VCC = 2.5 V while interfacing with 5 V inputs?

Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC, so 5 V signals may be applied directly when VCC = 2.5 V. The outputs will swing between 0 V and 2.5 V, maintaining valid CMOS logic levels for downstream 2.5 V receivers. No external clamping or level-shifting circuitry is required.

What is the maximum capacitive load this device can drive reliably?

The device is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤ 7.5 ns at 5 V). For loads exceeding 50 pF, propagation delay increases linearly; slew rate remains stable up to 100 pF. For >100 pF, add series termination or reduce edge rate using input RC filtering to avoid ringing and ensure signal integrity.

Is there a risk of bus contention when both outputs are enabled simultaneously?

No. Each output (1Y and 2Y) is electrically isolated; they share no internal connection. Contention occurs only if external wiring connects 1Y and 2Y to the same net. The IC itself imposes no restriction on concurrent enablement - both channels may drive their respective loads simultaneously without interference or increased power dissipation.

Does this part support hot insertion or live bus connection?

It supports hot insertion only when VCC is present and stable prior to applying input signals. The overvoltage-tolerant inputs protect against damage during signal application before power-up, but GND must be established first. For true hot-swap operation, external series resistors (10–22 Ω) and TVS diodes are recommended to limit inrush current and suppress transients on long cables.
