NXP Semiconductors 74AUP2G241GD,125

Overview

74AUP2G241GD,125 from Nexperia is a low-power dual non-inverting buffer/line driver with independent 3-state outputs, designed for voltage-level translation and bus isolation in ultra-low-power systems operating from 0.8 V to 3.6 V. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and input-disable functionality enabling floating-input tolerance. Used in portable sensor interfaces and battery-powered microcontroller I/O expansion.

For engineers reviewing the 74AUP2G241GD,125 datasheet, 74AUP2G241GD,125 pinout, 74AUP2G241GD,125 application, or 74AUP2G241GD,125 equivalent, key selection criteria include its 0.9 μA max ICC at 3.6 V, asymmetric output enable logic (1OE active LOW, 2OE active HIGH), -40 °C to +125 °C operation, and XSON8 (SOT1116) 1.2 × 1.0 × 0.35 mm package with 8 terminals.

Technical Context

This device implements two independent buffer channels, each with non-inverting signal path and separate 3-state control: 1Y is enabled by LOW on 1OE, while 2Y is enabled by HIGH on 2OE. The Schmitt-trigger inputs ensure robust operation across slow-rising signals and full VCC range (0.8–3.6 V), eliminating external hysteresis components.

IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V, and input-disable behavior deactivates 1A when 1OE = HIGH and 2A when 2OE = LOW-critical for hot-swap and multi-voltage domain interfacing in space-constrained embedded designs.

FAQ

What is the maximum capacitive load the 74AUP2G241GD,125 can drive while maintaining guaranteed propagation delay?

The device is characterized up to 30 pF load capacitance across all VCC conditions. At VCC = 3.3 V and CL = 30 pF, tPD remains ≤6.1 ns (typical), meeting timing budgets for 100+ MHz clocked interfaces. Exceeding 30 pF increases delay nonlinearly and may violate setup/hold margins in synchronous systems.

Can 1OE and 2OE be tied together for synchronized 3-state control?

No - 1OE is active LOW while 2OE is active HIGH, so tying them directly causes conflicting enable states. To synchronize both outputs, invert one enable signal externally (e.g., using a 74AUP1G04) or use separate control logic with complementary drive.

Does the input-disable feature affect propagation delay when the input is disabled?

No - propagation delay is only defined when the corresponding OE is asserted and the output is enabled. When 1A or 2A is disabled (e.g., 1OE = HIGH), the input stage is electrically isolated; no delay specification applies, and the output remains in high-impedance state regardless of input voltage.

Is the 74AUP2G241GD,125 compatible with 1.0 V core logic in modern microcontrollers?

Yes - it operates down to 0.8 V VCC with guaranteed VIH/VIL thresholds (e.g., VIH = 0.65×VCC min at 1.1 V), supporting direct connection to 1.0 V FPGA I/O banks and ARM Cortex-M0+ cores without level-shifting circuitry.
