Product details
Overview
74AUP2G79GS,115 from Nexperia is a low-power dual positive-edge-triggered D-type flip-flop in XSON8 (SOT1203) package, operating from 0.8 V to 3.6 V supply. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and guaranteed operation from –40 °C to +125 °C. Used in battery-powered logic synchronization, clock domain crossing, and level-shifting interfaces in portable instrumentation.
For engineers reviewing the 74AUP2G79GS,115 datasheet, 74AUP2G79GS,115 pinout, 74AUP2G79GS,115 application, or 74AUP2G79GS,115 equivalent, key selection criteria include ultra-low ICC (≤1.4 μA max), sub-1 ns set-up time at 3.3 V, 8-terminal XSON8 footprint compatibility, and JEDEC-compliant voltage thresholds across 0.8–3.6 V rails.
Technical Context
This device implements two independent D-type latches synchronized to the LOW-to-HIGH transition of their respective clock inputs (1CP, 2CP). Data on 1D/2D is sampled only at the rising edge and transferred to 1Q/2Q outputs with propagation delay as low as 0.9 ns (VCC = 3.3 V, CL = 5 pF).
Schmitt-trigger inputs enable robust operation with slow-rising signals (Δt/ΔV ≤ 200 ns/V), while IOFF isolates outputs during power-down to prevent backflow current. The design supports mixed-voltage interfacing, with inputs tolerant up to 3.6 V regardless of VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (VCC = 3.3 V) | 1.4 μA - Ensures negligible static power draw in always-on subsystems like real-time clocks or wake-up controllers. |
| Propagation Delay (tpd) | 0.9 ns (min) at VCC = 3.3 V, CL = 5 pF - Supports >500 MHz clock rates in high-speed sampling paths. |
| Set-up Time (tsu) | 0.6 ns (max) at VCC = 3.3 V - Allows tight timing margins in synchronous data capture circuits. |
| IOFF Leakage (VCC = 0 V) | ±0.75 μA - Limits back-current to <1 μA when powered off, protecting upstream drivers in hot-swap systems. |
| Input Voltage Tolerance | 0 V to 3.6 V - Permits connection to higher-voltage control signals (e.g., 3.3 V GPIO driving 1.8 V logic core). |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control enclosures. |
Pinout & Package
XSON8 package (SOT1203): extremely thin, leadless, 8-terminal surface-mount outline measuring 1.35 mm × 1.0 mm × 0.35 mm body height; optimized for space-constrained PCB layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 2D | Second data input - Latched into 2Q on next rising edge of 2CP; accepts voltages up to 3.6 V independent of VCC. |
| 2 | 1Q | First output - Drives downstream logic with VOH ≥ 2.3 V / VOL ≤ 0.5 V at 4 mA load (VCC = 3.0 V). |
| 3 | VCC | Power supply - Must be decoupled locally; supports full 0.8–3.6 V range with monotonic performance. |
| 4 | 2CP | Second clock input - Rising-edge sensitive; Schmitt-triggered to reject noise on slow clock edges. |
| 5 | 2Q | Second output - Electrically identical to 1Q; enables dual-channel synchronization without external buffering. |
| 6 | 1D | First data input - Sampled on rising edge of 1CP; same voltage tolerance and noise immunity as 2D. |
| 7 | 1CP | First clock input - Independent timing channel; allows asynchronous dual-data-path registration. |
| 8 | GND | Ground reference - Shared return path for all I/O and supply; requires low-impedance PCB plane connection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 1.4 μA max over full temperature and voltage range - extends battery life in IoT sensor nodes. |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.3 V typical at VCC = 1.8 V - eliminates false triggering from EMI or slow RC-clock edges. |
| IOFF partial power-down | Output disable at VCC = 0 V with leakage < ±0.75 μA - prevents bus contention during system sleep states. |
| JEDEC-compliant voltage thresholds | VIH/VIL specified per JESD8-12 through JESD8-B - ensures interoperability across legacy and modern logic families. |
| High ESD robustness | HBM > 5000 V, CDM > 1000 V - reduces handling damage risk during manual assembly and field maintenance. |
Applications
| Portable Medical Sensors | Automotive Body Control Module |
|---|---|
|
Use Scenario: Synchronizing analog sensor readings (e.g., temperature, pressure) to a low-power MCU clock domain in wearable health monitors. IC Role / Device Role / Timing Role: Dual D-flip-flop captures two independent sensor data streams on separate clock edges, eliminating metastability in asynchronous sampling. Use Value: Sub-1 ns tsu and 0.8–3.6 V operation allow direct interface with 1.8 V ADCs and 3.3 V microcontrollers without level shifters or additional power rails. |
Use Scenario: Debouncing and synchronizing mechanical switch inputs (door latch, seat position) before feeding to vehicle CAN controller. IC Role / Device Role / Timing Role: Each flip-flop registers one switch signal, rejecting contact bounce and aligning transitions to system clock for deterministic interrupt generation. Use Value: Schmitt-trigger inputs tolerate slow, noisy switch waveforms; –40 °C to +125 °C rating ensures reliability in cabin and under-hood environments. |
| Industrial PLC I/O Expansion | Low-Power Wireless Transceiver Interface |
|
Use Scenario: Isolating and retiming digital I/O signals between isolated field-side and controller-side PCB sections in programmable logic controllers. IC Role / Device Role / Timing Role: Provides clean, jitter-free clock-domain crossing for status and command signals across galvanic isolation barriers. Use Value: IOFF functionality prevents leakage current when either side is powered down, maintaining isolation integrity during partial system shutdown. |
Use Scenario: Synchronizing packet-ready flags and interrupt requests between ultra-low-power RF SoC and host application processor in BLE/Wi-Fi modules. IC Role / Device Role / Timing Role: Registers asynchronous event signals from transceiver to match host CPU clock domain, preventing missed interrupts. Use Value: 1.4 μA max ICC minimizes quiescent current impact on battery runtime; 8-pin XSON8 footprint saves board area in compact module designs. |
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, wider VCC (1.65–5.5 V), larger VSSOP8 package | Requires external power-down management; suited for 5 V-tolerant industrial systems | Select when 5 V interface capability is required and ultra-low standby current is not critical. |
| 74LVC2G79GW,125 | Same XSON8 footprint, but lacks Schmitt-trigger inputs and IOFF; rated only to +85 °C | Not suitable for noisy environments or partial power-down use cases; limited thermal range | Choose only for cost-sensitive consumer applications where ambient temperature stays below 85 °C. |
Compared with SN74LVC2G74DCUR and 74LVC2G79GW,125, the 74AUP2G79GS,115 uniquely combines sub-μA static current, Schmitt-trigger noise immunity, IOFF protection, and extended temperature support - making it optimal for battery-critical, harsh-environment, and mixed-voltage embedded designs.

FAQ
Does 74AUP2G79GS,115 support true bidirectional data flow?
No. The 74AUP2G79GS,115 is a unidirectional D-type flip-flop: data flows only from D inputs to Q outputs on clock edges. It has no tri-state or direction-control logic. For bidirectional bus interfacing, external multiplexing or dedicated transceivers are required.
Can 74AUP2G79GS,115 operate reliably at 0.85 V supply?
Yes. The device is fully characterized from 0.8 V to 3.6 V, including propagation delay (19.7 ns max at VCC = 0.8 V, CL = 5 pF), set-up time (3.4 ns max), and VIH/VIL thresholds. All static and dynamic parameters meet specification across this range.
What is the maximum capacitive load each output can drive?
Each output is rated for 20 mA sink/source current, supporting typical loads up to 50 pF with minimal timing degradation. For CL > 30 pF, propagation delay increases linearly (e.g., +10 ns at CL = 30 pF vs. CL = 5 pF at VCC = 3.3 V); layout decoupling remains critical.
Is pin 1 marking visible on the 74AUP2G79GS,115 XSON8 package?
Yes. Per datasheet Figure 5 and Table 2, pin 1 is indicated by a laser-marked dot located in the lower-left corner of the package, adjacent to the "pP" marking code - confirmed for SOT1203 (XSON8) variant.
