Product details
Overview
74AUP2G79DC-Q100 from Nexperia is a dual positive-edge-triggered D-type flip-flop in VSSOP8 package, operating across 0.8 V to 3.6 V supply, with 1.4 μA max ICC at −40 °C to +125 °C, Schmitt-trigger inputs for noise immunity, and IOFF circuitry enabling partial power-down mode. It serves as a synchronous storage element in automotive clock-domain crossing and signal synchronization circuits.
For engineers reviewing the 74AUP2G79DC-Q100 datasheet, 74AUP2G79DC-Q100 pinout, 74AUP2G79DC-Q100 application, or 74AUP2G79DC-Q100 equivalent, this page delivers verified functional identity, automotive-grade timing parameters, VSSOP8 package mapping, IOFF-enabled power management behavior, and AEC-Q100 Grade 1 qualification context - all extracted from Nexperia's official Rev. 4 product data sheet (July 2023).
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal logic; each responds solely to its dedicated clock (1CP/2CP) and data (1D/2D) inputs. The Schmitt-trigger input structure ensures robust operation with slow-rising/falling signals across the full 0.8 V–3.6 V VCC range.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA, satisfying partial power-down requirements in mixed-voltage automotive subsystems. Propagation delay ranges from 0.9 ns (VCC = 3.3 V, CL = 5 pF) to 2.8 ns (VCC = 3.3 V, CL = 30 pF), with maximum operating frequency up to 510 MHz at VCC = 3.3 V and CL = 5 pF.
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 (Tamb = −40 °C to +125 °C) | 1.4 μA - supports ultra-low static power in always-on automotive modules |
| IOFF Leakage (VCC = 0 V) | ±0.75 μA - prevents damaging back-current during hot-swap or partial system shutdown |
| tpd (VCC = 3.3 V, CL = 5 pF) | 0.9 ns to 4.4 ns - defines minimum clock-to-output latency for high-speed sampling paths |
| fmax (VCC = 3.3 V, CL = 5 pF) | 510 MHz - supports high-frequency data capture in ADAS sensor preprocessing chains |
| tsu / th (VCC = 3.3 V) | 1.0 ns set-up / 0 ns hold - simplifies timing closure in compact PCB layouts with minimal routing skew |
| Input Voltage Tolerance | Up to 3.6 V - allows interfacing with higher-voltage peripherals while powered from lower VCC |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1), 8 leads, body width 2.3 mm, pin 1 indicator located on lower left corner below marking code "p79".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 (1CP, 2CP) | Clock pulse input | Positive-edge sensitive; triggers state transfer only on LOW-to-HIGH transition |
| 2, 6 (1D, 2D) | Data input | Schmitt-triggered; accepts slow edges and rejects noise across full VCC range |
| 3, 7 (2Q, 1Q) | Data output | CMOS-compatible; drives standard logic loads with VOH ≥ 2.3 V / VOL ≤ 0.5 V at VCC = 3.0 V |
| 4 | GND | Reference ground (0 V); must be low-impedance connection for stable switching |
| 8 | VCC | Supply voltage input; decoupling capacitor required within 5 mm for EMI suppression |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Rated for −40 °C to +125 °C ambient operation - validated for engine bay and ADAS ECU deployment |
| IOFF partial power-down | Outputs disabled at VCC = 0 V with leakage ≤ ±0.75 μA - enables safe integration into multi-rail automotive power architectures |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V typical at VCC = 3.3 V - eliminates false triggering from noisy CAN/LIN bus-coupled signals |
| Ultra-low dynamic power | CPD = 2.7 pF at VCC = 3.3 V - reduces switching power to < 30 μW per flip-flop at 10 MHz toggle rate |
| Wide VCC compatibility | Functional across JEDEC standards JESD8-12 through JESD8-B - interoperable with legacy and next-gen low-voltage SoCs |
Applications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G74DCUR | Higher ICC (10 μA typ), no IOFF, 1.65 V–5.5 V VCC range | Lacks AEC-Q100 qualification; not rated for automotive under-hood use | Select only for industrial or consumer designs where extended voltage range outweighs automotive compliance needs |
| 74LVC2G79GW,125 | Same VSSOP8 package, but only qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C) | Lower max ambient rating limits use in high-temp engine compartments or EPS modules | Acceptable for cabin-infotainment or HVAC control where ambient stays ≤ +105 °C |

FAQ
What is the minimum recommended VCC for guaranteed operation at −40 °C?
The device is fully specified down to 0.8 V across −40 °C to +125 °C. At VCC = 0.8 V, propagation delay increases to 14.2 ns (CL = 5 pF), and fmax drops to 170 MHz, but all logic functions remain deterministic per Table 7 and Table 8. No derating or external biasing is required.
Does the IOFF feature require external control signals or enable pins?
No. IOFF activates automatically when VCC = 0 V - no external enable/disable signal is needed. The circuitry monitors VCC internally and disables outputs within nanoseconds of power removal, limiting backflow current to ±0.75 μA regardless of input/output voltage states.
Can 74AUP2G79DC-Q100 drive a 50 Ω transmission line directly?
No. Its CMOS outputs are designed for capacitive loads up to 50 pF (per datasheet CL test conditions), not 50 Ω resistive termination. Driving a 50 Ω line would exceed ±20 mA output current rating and distort logic levels. A dedicated line driver or series resistor matching is required.
How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?
Schmitt-trigger inputs provide ≥0.3 V hysteresis (typical at VCC = 3.3 V), meaning VIH and VIL thresholds differ by that amount. This prevents multiple toggles during slow or noisy signal transitions - critical for reliable operation near alternators, motors, or unshielded harnesses in automotive environments.
