Nexperia USA Inc. 74LVC2G241GM,125

Overview

74LVC2G241GM,125 from Nexperia is a dual non-inverting 3-state buffer/line driver in XQFN8 (SOT902-2) package, operating from 1.65 V to 5.5 V supply. It features independent active-low (1OE) and active-high (2OE) enable controls, ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF circuitry for partial power-down protection. It serves as a level translator between 3.3 V and 5 V logic domains in compact I/O expansion interfaces.

For engineers reviewing the 74LVC2G241GM,125 datasheet, 74LVC2G241GM,125 pinout, 74LVC2G241GM,125 application, or 74LVC2G241GM,125 equivalent, key selection criteria include dual independent 3-state control timing (enable/disable times ≤ 4.8 ns), 5 V-tolerant inputs with 1.65 V minimum VCC, thermal performance in XQFN8 (derates 4.0 mW/K above 85 °C), and compliance with JEDEC JESD8-7/5/B standards for mixed-voltage interfacing.

Technical Context

The device implements two independent non-inverting buffers, each with separate output-enable logic: 1OE is active LOW (pin 1), 2OE is active HIGH (pin 7). Schmitt-trigger inputs ensure robust operation with slow-rising signals (Δt/ΔV ≥ 10 ns/V at VCC ≥ 2.7 V). The IOFF circuit disables outputs and blocks backflow current when VCC = 0 V, enabling hot-swap and partial power-down use cases.

Input voltage thresholds are rail-relative: VIH = 0.7×VCC (min) at 4.5–5.5 V, VIL = 0.3×VCC (max); output drive strength is asymmetric-VOH ≥ VCC − 0.1 V (IO = −100 μA), VOL ≤ 0.55 V (IO = 32 mA, VCC = 4.5 V). Propagation delay ranges from 2.1 ns (typ, VCC = 5 V) to 4.7 ns (max, VCC = 3.0 V) per buffer path.

FAQ

What is the function of the IOFF circuit in the 74LVC2G241GM,125?

The IOFF circuit disables both outputs and blocks current flow through the device when VCC = 0 V, preventing damaging backfeed current from live I/O lines into a powered-down system. This feature is essential for hot-swap capability and safe multi-rail power sequencing in industrial and automotive systems.

Can the 74LVC2G241GM,125 operate with a 1.8 V supply while interfacing with 5 V inputs?

Yes. The device supports VCC as low as 1.65 V and tolerates input voltages up to 5.5 V regardless of supply level. At 1.8 V VCC, VIH is guaranteed ≥ 1.26 V and VIL ≤ 0.54 V, enabling reliable detection of 5 V logic levels without external level translation.

How does the Schmitt-trigger input improve noise immunity?

Schmitt-trigger inputs provide hysteresis-typically ≥ 0.3 V at 3.3 V VCC-so rising and falling input thresholds differ. This prevents multiple output transitions caused by slow or noisy edges, making the device resilient to EMI, crosstalk, and long trace ringing in industrial control and automotive wiring harnesses.

Is the thermal pad on the 74LVC2G241GM,125's XQFN8 package required to be soldered?

Yes. The exposed thermal pad (pin 9, not electrically connected) must be soldered to a dedicated PCB copper pour for effective heat dissipation. Omitting this connection degrades thermal resistance by >40 %, risking exceeding Ptot limits under sustained 24 mA output loading at elevated ambient temperatures.
