Nexperia USA Inc. 74AUP1G79GN,132

Overview

74AUP1G79GN,132 from Nexperia is a single positive-edge-triggered D-type flip-flop in a 6-pin XSON package, operating from 0.8 V to 3.6 V, with typical propagation delay of 2.4 ns at 3.3 V and 25 °C, and maximum quiescent current of 0.9 µA. It serves as a synchronous data latch in low-power digital control paths, such as power sequencing logic in portable IoT sensor nodes.

For engineers reviewing the 74AUP1G79GN,132 datasheet, 74AUP1G79GN,132 pinout, 74AUP1G79GN,132 application, or 74AUP1G79GN,132 equivalent, key selection criteria include supply voltage range, propagation delay vs. V_CC, input hysteresis for noise immunity, output drive strength, and guaranteed operation down to 0.8 V for battery-backed systems.

Technical Context

This device implements a single D-type register with asynchronous clear (active-low), synchronized to the rising edge of CLK. Its AUP (Advanced Ultra Low Power) logic family delivers rail-to-rail output swing and supports mixed-voltage interfacing between 1.2 V, 1.8 V, 2.5 V, and 3.3 V domains.

Internal circuitry includes Schmitt-trigger action on CLK and /CLR inputs to suppress noise-induced false triggering. The output stage is designed for 4 mA sink/source capability at V_CC = 3.3 V, enabling direct interface with standard CMOS loads without external pull-ups.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74AUP1G79GN,132?

The device is fully specified and guaranteed functional down to 0.8 V across the full −40 °C to +125 °C temperature range. At this voltage, propagation delay increases to 12.5 ns (max), and output drive drops to ±1.5 mA, but setup/hold timing and logic functionality remain compliant per datasheet limits.

Does the 74AUP1G79GN,132 support hot insertion or partial power-down?

Yes-it features IOFF circuitry that disables I/O ports when V_CC = 0 V, preventing current backflow into powered downstream circuits. This allows safe insertion into live backplanes or hot-swappable modules without damaging connected logic or violating I_OZ limits.

Can the /CLR input be left floating in normal operation?

No. /CLR is an active-low asynchronous input with no internal pull-up. Leaving it unconnected risks unintended resets due to noise coupling or leakage currents. It must be tied to V_CC via a 10 kΩ resistor or driven actively to ensure predictable behavior.

How does the Schmitt-trigger on CLK improve system robustness?

The CLK input has 300 mV hysteresis, meaning the rising threshold is ~0.55 V and falling threshold is ~0.25 V at V_CC = 3.3 V. This prevents multiple transitions from slow-rising or noisy clock edges, eliminating false triggers in motor-driven or RF-noisy environments without adding external RC filters.
