Nexperia USA Inc. 74AUP2G241GM,125

Overview

74AUP2G241GM,125 from Nexperia is a dual non-inverting buffer/line driver with independent 3-state outputs, designed for low-voltage logic interfacing in space-constrained applications. It operates across 0.8 V to 3.6 V supply, delivers <0.9 μA max ICC, features Schmitt-trigger inputs for noise immunity, and supports partial power-down via IOFF circuitry. Used in portable sensor interfaces and battery-powered MCU I/O expansion.

For engineers reviewing the 74AUP2G241GM,125 datasheet, 74AUP2G241GM,125 pinout, 74AUP2G241GM,125 application, or 74AUP2G241GM,125 equivalent, key selection criteria include its dual-channel 3-state control (1OE active-low, 2OE active-high), ultra-low static power at 0.8 V, IOFF-enabled safe bus isolation during power-down, and compatibility with 1.2 V, 1.8 V, and 3.3 V logic domains.

Technical Context

This device implements two independent non-inverting buffers, each with separate output-enable controls: 1OE (active LOW) and 2OE (active HIGH). The asymmetrical enable polarity allows flexible bus arbitration-e.g., one channel enabled by default while the other requires explicit activation.

Schmitt-trigger inputs ensure robust operation with slow-rising signals across the full 0.8–3.6 V VCC range, and the IOFF circuit blocks backflow current when VCC = 0 V, enabling hot-swap and partial power-down system architectures without signal contention.

FAQ

What is the maximum capacitive load the 74AUP2G241GM,125 can drive while maintaining specified propagation delay?

The datasheet specifies tpd performance up to CL = 30 pF across all VCC conditions. At VCC = 3.3 V and CL = 30 pF, typical propagation delay is 4.6 ns (max 8.3 ns), confirming reliable operation into standard PCB traces, connectors, and small FET gates without added series termination.

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

No - 1OE is active-LOW and 2OE is active-HIGH, so tying them directly causes conflicting logic states. To synchronize both outputs, invert one enable signal externally or use discrete logic; the asymmetry is intentional for independent bus arbitration.

Does the 74AUP2G241GM,125 require external pull-up or pull-down resistors on its inputs?

No - Schmitt-trigger inputs provide inherent hysteresis and defined thresholds across the full VCC range; floating inputs are safely disabled via the input-disable feature when their respective OE is asserted, eliminating need for external biasing.

How does the IOFF feature behave when VCC is ramping during power-up?

IOFF activates automatically when VCC drops below ~0.2 V and remains active until VCC exceeds ~0.5 V; during this transition, output leakage is limited to ±0.75 μA, preventing latch-up or bus contention even with inputs held static at valid logic levels.
