Nexperia USA Inc. 74AHC2G241DP,125

Overview

74AHC2G241DP,125 from Nexperia is a dual 1-bit non-inverting buffer/line driver with independent 3-state outputs, designed for bidirectional bus interfacing and level translation in mixed-voltage systems. It operates from 2.0 V to 5.5 V, supports CMOS-level inputs, delivers ±8 mA output drive at 4.5 V, and is rated for -40 °C to +125 °C operation in TSSOP8 (SOT505-2) package.

For engineers reviewing the 74AHC2G241DP,125 datasheet, 74AHC2G241DP,125 pinout, 74AHC2G241DP,125 application, or 74AHC2G241DP,125 equivalent, key selection criteria include independent active-low/active-high enable control (1OE/2OE), overvoltage-tolerant inputs up to 5.5 V, propagation delay ≤5.5 ns at 5 V/15 pF, 3-state leakage <10 μA, and thermal derating above 96 °C.

Technical Context

This device implements two independent buffer channels, each with dedicated output-enable logic: 1OE is active LOW, 2OE is active HIGH-enabling flexible bus arbitration and direction control without external inversion. Each channel features symmetrical output impedance and balanced tPLH/tPHL delays, critical for timing-critical data latching and clock distribution.

Input overvoltage tolerance (up to 5.5 V regardless of VCC) allows safe interfacing between 3.3 V logic driving 5 V buses or legacy TTL subsystems. The CMOS input structure ensures low static current (<40 μA at VCC = 5.5 V) and high noise immunity (>40% VCC), while the 3-state outputs support hot-swap and multi-drop bus topologies.

FAQ

What is the maximum clock frequency supported by the 74AHC2G241DP,125?

The device does not function as a clock generator or synchronizer, but its propagation delay (≤5.5 ns at 5 V/15 pF) supports reliable data transfer up to ~100 MHz in point-to-point configurations. Maximum usable frequency depends on trace capacitance, termination, and fanout; for 50 pF loads, tpd increases to ≤7.5 ns, limiting practical edge rates to ~70 MHz.

Can 74AHC2G241DP,125 be used to translate between 3.3 V and 5 V logic without external components?

Yes - its overvoltage-tolerant inputs accept 0–5.5 V signals regardless of VCC setting, allowing direct connection of 5 V outputs to 3.3 V-powered 74AHC2G241DP,125 inputs. When VCC = 3.3 V, outputs swing rail-to-rail (0–3.3 V), so external level-shifting is required for 5 V output compatibility.

How does the dual enable architecture (1OE active LOW, 2OE active HIGH) benefit system design?

This asymmetry eliminates the need for external inverters when coordinating with controllers that provide complementary enable signals - for example, one MCU GPIO can directly drive 1OE while its inverted copy (or a second GPIO) drives 2OE, enabling precise half-duplex bus control or interleaved channel activation without added propagation delay or component count.

Is thermal derating required for continuous operation at +125 °C ambient?

Yes - the TSSOP8 package (SOT505-2) has a total power dissipation limit of 250 mW at Tamb ≤96 °C, derating linearly by 4.6 mW/K above that temperature. At +125 °C, maximum allowable Ptot drops to 122 mW, corresponding to ~15 mA average output current per channel at 5 V, necessitating careful power budgeting in thermally constrained enclosures.
