Product details
Overview
74AUP2G79GN,115 from Nexperia is a low-power dual positive-edge-triggered D-type flip-flop in an XSON8 package (1.2 × 1.0 × 0.35 mm, SOT1116), operating from 0.8 V to 3.6 V supply. It transfers data from inputs 1D/2D to outputs 1Q/2Q on the LOW-to-HIGH clock transition, features Schmitt-trigger inputs for noise immunity, and includes IOFF circuitry for partial power-down protection. It is specified for automotive-grade temperature range (−40 °C to +125 °C) and used in battery-powered sensor interfaces and low-voltage logic synchronization.
For engineers reviewing the 74AUP2G79GN,115 datasheet, 74AUP2G79GN,115 pinout, 74AUP2G79GN,115 application, or 74AUP2G79GN,115 equivalent, key selection criteria include its ultra-low ICC (≤1.4 μA max at −40 °C to +125 °C), 0.8 V minimum VCC support, IOFF-enabled power-gating capability, and dual-channel edge-triggered storage with independent clock inputs.
Technical Context
This device implements two independent D-type latches synchronized to rising edges of separate clock inputs (1CP, 2CP), each requiring stable data (1D/2D) one setup time (tsu ≤ 1.0 ns at VCC = 3.6 V) before the clock transition. Its Schmitt-trigger inputs tolerate slow signal edges across the full 0.8–3.6 V VCC range, enabling robust operation in noisy mixed-signal environments.
The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for system-level power sequencing in portable and automotive electronics. Static power consumption remains below 1.4 μA across the full industrial temperature range, and propagation delay is as low as 0.9 ns (VCC = 3.0–3.6 V, CL = 5 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct interface with 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| ICC (max) | 1.4 μA at −40 °C to +125 °C - enables multi-year battery life in always-on sensor nodes |
| tsu / th | 1.0 ns / 0 ns at VCC = 3.6 V - minimal timing margin required for high-speed synchronous sampling |
| fmax | 510 MHz at VCC = 3.6 V, CL = 5 pF - suitable for clock-domain crossing in sub-GHz digital subsystems |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - prevents destructive current flow during hot-swap or power-rail sequencing |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive and industrial control applications |
| ESD Rating | HBM >5000 V, CDM >1000 V - withstands handling and board-level ESD events without protection diodes |
Pinout & Package
XSON8 package (SOT1116): extremely thin small outline, no leads, 8-terminal surface-mount with body dimensions 1.2 mm × 1.0 mm × 0.35 mm; pin 1 indicator located below marking code "pP" at lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 2D | Second D-type data input - sampled on rising edge of 2CP |
| 2 | 1Q | First Q output - reflects state of 1D after 1CP rising edge |
| 3 | VCC | Positive supply rail - powers both flip-flop channels and internal bias networks |
| 4 | 2CP | Second clock input - rising edge triggers transfer of 2D to 2Q |
| 5 | 2Q | Second Q output - reflects state of 2D after 2CP rising edge |
| 6 | 1D | First D-type data input - sampled on rising edge of 1CP |
| 7 | 1CP | First clock input - rising edge triggers transfer of 1D to 1Q |
| 8 | GND | Ground reference - return path for all internal currents and IOFF discharge paths |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 1.4 μA over full temperature range - eliminates need for power gating in always-on logic |
| IOFF partial power-down | Outputs disabled with VCC = 0 V; leakage < ±0.75 μA - enables safe multi-rail sequencing |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.3 V at VCC = 3.6 V - rejects noise on slow-rising clock/data lines |
| Wide VCC compatibility | Operates down to 0.8 V - interoperable with advanced low-voltage microcontrollers and sensors |
| High ESD robustness | HBM >5000 V, CDM >1000 V - reduces need for external ESD protection components |
Applications
| IoT Sensor Node Timing | Automotive Body Control Module |
|---|---|
Use Scenario: Synchronizing asynchronous sensor interrupts (e.g., motion, temperature) to a low-power MCU clock domain while maintaining nanosecond-level timing integrity. IC Role / Device Role / Timing Role: Dual-edge-triggered register capturing event flags prior to wake-up, with independent clocks enabling staggered sampling. Use Value: Enables deterministic interrupt latency (<1 ns jitter) and eliminates metastability risk without external synchronizers. | Use Scenario: Isolating and debouncing switch inputs (door lock, window up/down) in 12 V vehicle systems using 3.3 V logic rails. IC Role / Device Role / Timing Role: Input latch holding mechanical switch state until polled by CAN-connected MCU; IOFF protects during sleep mode. Use Value: Reduces system-level current draw by 2.1 μA per channel vs. standard logic, extending battery reserve time. |
| Wearable Health Monitor | Industrial PLC I/O Expansion |
Use Scenario: Capturing biopotential waveform edges (ECG R-peak, SpO₂ pulse) into ultra-low-power SoC with sub-1 V supply. IC Role / Device Role / Timing Role: Level-shifting and edge-capturing front-end register interfacing analog comparators to digital processing core. Use Value: Operates at 0.8 V VCC - matches SoC's lowest active voltage, eliminating intermediate regulators. | Use Scenario: Adding isolated, glitch-free digital inputs to modular PLC backplanes where field wiring introduces noise and ground shifts. IC Role / Device Role / Timing Role: Noise-immune input conditioner with Schmitt-trigger inputs and independent clock domains per channel. Use Value: Eliminates false triggering from EMI transients up to 100 MHz due to 0.3 V hysteresis and 200 ns/V input slew tolerance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G74DCUR | Higher ICC (10 μA typ), no IOFF, VCC min = 1.65 V | Not suitable for 0.8–1.2 V systems or partial power-down sequences | Select when cost sensitivity outweighs ultra-low-power and multi-rail requirements |

FAQ
What is the maximum clock frequency supported by the 74AUP2G79GN,115?
The 74AUP2G79GN,115 achieves up to 510 MHz maximum clock frequency at VCC = 3.6 V with 5 pF load, dropping to 300 MHz at −40 °C to +125 °C. Performance scales with supply voltage: 480 MHz at 3.0 V, 270 MHz at 1.8 V, and 120 MHz at 1.2 V - all verified per JEDEC test conditions in the official datasheet.
Does the 74AUP2G79GN,115 support true bidirectional I/O or bus-hold functionality?
No. The 74AUP2G79GN,115 is a unidirectional dual D-type flip-flop with dedicated inputs (1D/2D, 1CP/2CP) and outputs (1Q/2Q). It does not implement bus-hold, weak pull-up/down, or tri-state drivers. Outputs are push-pull CMOS with VOH ≥ 2.3 V and VOL ≤ 0.5 V at VCC = 3.0 V and IO = ±4 mA.
Can the 74AUP2G79GN,115 be used with 0.8 V microcontrollers without level translation?
Yes. The device is fully specified from 0.8 V to 3.6 V, with VIH as low as 0.25×VCC and VIL as high as 0.30×VCC at 0.8 V - ensuring reliable recognition of logic HIGH/LOW from 0.8 V-core MCUs. Output VOH/VOL remain rail-to-rail compliant across this range, enabling direct connection.
How does the IOFF feature behave during power sequencing when VCC ramps from 0 V to nominal?
IOFF activates when VCC falls below ~0.2 V, disabling outputs and limiting leakage to ±0.75 μA even if inputs/outputs are biased to 3.6 V. During ramp-up, outputs remain in high-impedance until VCC exceeds ~0.5 V, preventing bus contention. This behavior is characterized across −40 °C to +125 °C and documented in Table 7 (IOFF and ΔIOFF parameters).
