Product details
Overview
74LVC1G79GV-Q100 from Nexperia is a single positive-edge-triggered D-type flip-flop in SC-74A (SOT753) package, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, IOFF-enabled partial power-down capability, and AEC-Q100 Grade 1 qualification for automotive body control modules requiring reliable edge-triggered data storage.
For engineers reviewing the 74LVC1G79GV-Q100 datasheet, 74LVC1G79GV-Q100 pinout, 74LVC1G79GV-Q100 application, or 74LVC1G79GV-Q100 equivalent, this device supports mixed-voltage level translation between 3.3 V and 5 V logic domains, delivers sub-6.5 ns propagation delay at 3.3 V, maintains robust noise immunity via Schmitt-trigger inputs, and enables safe power sequencing in automotive ECUs with its IOFF circuitry.
Technical Context
This flip-flop implements synchronous edge-triggered storage using CMOS logic with Schmitt-trigger inputs for tolerance to slow signal edges. Its IOFF feature actively disables outputs during power-down to prevent backflow current when VCC = 0 V.
The device supports dual-supply interoperability: inputs tolerate up to 5.5 V regardless of VCC, enabling direct interface with both 3.3 V and 5 V drivers while maintaining valid VIH/VIL thresholds across 1.65–5.5 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single D-type flip-flop, positive-edge triggered - stores D-input state on rising CP edge |
| Supply Voltage Range | 1.65 V to 5.5 V - supports wide-rail operation across automotive and industrial voltage domains |
| Propagation Delay (tpd) | 0.5 ns (min) to 6.5 ns (max) at VCC = 3.0–3.6 V - enables timing-critical sampling up to 450 MHz clock rate |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or moderate PCB traces without buffering |
| IOFF Support | Active at VCC = 0 V - blocks output current flow, preventing damage during hot-insertion or partial power-down |
| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C) - validated for under-hood automotive applications including lighting and gateway modules |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows use as bidirectional level translator in mixed-voltage systems |
Pinout & Package
SC-74A plastic surface-mounted package (SOT753), 5-lead, body dimensions 3.1 mm × 1.7 mm × 1.3 mm, thermal enhanced for automotive ambient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - D | Data input | Asynchronous data source sampled on rising CP edge; accepts 0–5.5 V signals regardless of VCC |
| 2 - CP | Clock pulse input | Positive-edge sensitive control signal; Schmitt-triggered for noise immunity on slow-rising clocks |
| 3 - GND | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for stable switching |
| 4 - Q | Data output | Registered output reflecting D state after CP rise; drives ±24 mA at 3.0 V with rail-to-rail swing |
| 5 - VCC | Supply voltage | Primary power rail (1.65–5.5 V); powers internal logic and enables IOFF behavior when de-energized |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in automotive powertrain and chassis systems |
| IOFF partial power-down mode | Prevents destructive back-current when VCC = 0 V, enabling safe multi-rail sequencing in ECU designs |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs even at VCC = 1.65 V - eliminates external level-shifting in mixed-voltage buses |
| Schmitt-trigger inputs | Enables reliable operation with slow-rise/fall clocks (≤10 ns/V) common in sensor interfaces and legacy modules |
| JEDEC-compliant voltage standards | Meets JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G79DBVR | Non-automotive grade (commercial −40 °C to +85 °C); identical pinout and electrical specs except AEC-Q100 qualification | Lacks automotive qualification and extended temperature validation; unsuitable for under-hood deployment | Select when cost sensitivity outweighs automotive reliability requirements and ambient stays ≤85 °C |
| 74LVC1G79GW-Q100 | TSSOP5 (SOT353-1) package instead of SC-74A; same die, identical electrical performance, 0.2 mm taller profile | Offers improved thermal dissipation (3.3 mW/K derating above 74 °C vs. 3.8 mW/K for SC-74A) but larger footprint | Select when PCB layout allows 2.2 mm × 1.3 mm area and higher thermal margin is prioritized over miniaturization |
Compared with SN74LVC1G79DBVR, the 74LVC1G79GV-Q100 adds AEC-Q100 Grade 1 compliance and extended +125 °C operation, while versus 74LVC1G79GW-Q100 it trades thermal performance for smaller SC-74A footprint-critical for space-constrained automotive modules.

FAQ
What is the maximum clock frequency supported by the 74LVC1G79GV-Q100?
The device supports up to 450 MHz maximum clock frequency at VCC = 3.0–3.6 V and −40 °C to +85 °C ambient, verified per dynamic characteristics Table 8. At full Grade 1 range (−40 °C to +125 °C), fmax drops to 160 MHz for VCC ≥ 2.7 V due to increased propagation delay and reduced drive strength at elevated temperature.
Does the 74LVC1G79GV-Q100 require external pull-up or pull-down resistors on its inputs?
No external biasing is required: all inputs feature Schmitt-trigger action with hysteresis, ensuring clean switching even with slow-rising signals or floating nodes. Input leakage remains below ±1 μA across temperature, eliminating need for passive termination in most automotive signal conditioning circuits.
How does the IOFF function behave during system power-down sequences?
When VCC drops to 0 V, the IOFF circuitry automatically disables both Q output and internal logic paths, limiting output leakage to ±2 μA (per Table 7). This prevents back-current flow into powered-down sections, protecting downstream components during staggered rail shutdown in multi-voltage ECUs.
Can the 74LVC1G79GV-Q100 interface directly with 5 V TTL logic outputs?
Yes - its inputs tolerate up to 5.5 V regardless of VCC setting, and VIH threshold is 0.7 × VCC minimum (e.g., 2.1 V at VCC = 3.0 V), fully compatible with standard 5 V TTL VOH (≥2.4 V). No level-shifter needed when connecting to legacy 5 V peripherals in modern 3.3 V automotive domains.
