Product details
Overview
74LVC1G79GW-Q100 from Nexperia is a single positive-edge-triggered D-type flip-flop in TSSOP5 (SOT353-1) package, rated for automotive Grade 1 (-40 °C to +125 °C), with 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, and IOFF partial power-down capability. It functions as a synchronous data latch in timing-critical control paths of engine control units and ADAS sensor interfaces.
For engineers reviewing the 74LVC1G79GW-Q100 datasheet, 74LVC1G79GW-Q100 pinout, 74LVC1G79GW-Q100 application, or 74LVC1G79GW-Q100 equivalent, key selection criteria include its AEC-Q100 qualification, Schmitt-trigger input tolerance for slow-rising signals, 5.0 ns max propagation delay at 3.3 V, IOFF-enabled safe power sequencing, and mixed-voltage 3.3 V/5 V interface compatibility.
Technical Context
This device implements a single-bit synchronous storage element with non-inverting Q output, triggered exclusively on LOW-to-HIGH clock transitions. Its Schmitt-trigger inputs accept slow-rising waveforms up to 20 ns/V (at 1.65–2.7 V) or 10 ns/V (at 2.7–5.5 V), enabling robust operation in noisy automotive environments.
The IOFF circuit activates when VCC = 0 V, disabling outputs and blocking backflow current from live buses-critical for hot-swap and multi-rail power sequencing. Input voltage tolerance extends to 5.5 V regardless of VCC, allowing direct interfacing with 5 V logic while powered from 1.8 V or 3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single D-type flip-flop with positive-edge clock trigger and non-inverting Q output |
| Supply Voltage Range | 1.65 V to 5.5 V - supports mixed-voltage system integration without level shifters |
| Propagation Delay (tpd) | 5.0 ns max at VCC = 3.3 V - enables reliable operation up to 450 MHz clock frequency |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or small capacitive traces |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures safe isolation during partial power-down |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows 5 V signal input while operating at 1.8 V |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - D | Data input | Asynchronous data source sampled on rising CP edge; accepts 0–5.5 V with Schmitt-trigger hysteresis |
| 2 - CP | Clock pulse input | Positive-edge sensitive; triggers state capture only on LOW-to-HIGH transition |
| 3 - GND | Ground reference | 0 V return path for all internal circuitry and I/O; must be low-impedance in automotive PCB layout |
| 4 - Q | Data output | Non-inverting registered output; drives ±24 mA at 3.0 V with VOH ≥ 2.3 V / VOL ≤ 0.55 V |
| 5 - VCC | Supply voltage | Primary power rail (1.65–5.5 V); powers internal logic and enables IOFF when at 0 V |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| SN74LVC1G79DRYR | TI part in 5-pin X2SON (DSBGA) package; identical logic function but no AEC-Q100 qualification | Rated for industrial (-40 °C to +85 °C), not automotive; lacks IOFF and extended temp validation | Select only for non-automotive designs where board space is constrained and qualification is not required |
| 74LVC1G79GV-Q100 | Nexperia SC-74A (SOT753) variant; same electrical specs, different mechanical footprint and thermal resistance | Same AEC-Q100 Grade 1 rating and IOFF behavior; lower thermal dissipation margin due to larger pad thermal resistance | Prefer GW for higher-power-density layouts; choose GV only if legacy SC-74A land pattern reuse is mandatory |
Compared with SN74LVC1G79DRYR, the 74LVC1G79GW-Q100 provides guaranteed automotive qualification and IOFF protection; versus 74LVC1G79GV-Q100, it offers superior thermal performance in TSSOP5 for sustained high-frequency operation in compact ECUs.

FAQ
Does the 74LVC1G79GW-Q100 support 1.8 V operation?
Yes. The device is fully specified from 1.65 V to 5.5 V, with VIH minimum of 0.65 × VCC and VIL maximum of 0.35 × VCC at 1.65–1.95 V operation. Static and dynamic parameters-including 9.9 ns max propagation delay and 2.5 ns min setup time-are guaranteed across this range.
What is the purpose of the IOFF feature, and how does it behave?
IOFF disables outputs when VCC = 0 V, preventing backflow current from live I/O lines into a powered-down device. Measured IOFF leakage is ≤±2 μA at 5.5 V applied to D, CP, or Q while VCC is grounded-enabling safe hot-swap and multi-rail power sequencing in automotive gateways.
Can the 74LVC1G79GW-Q100 interface directly with 5 V TTL logic?
Yes. Inputs tolerate up to 5.5 V regardless of VCC, and output VOH reaches ≥3.4 V at VCC = 4.5 V driving –32 mA, satisfying TTL HIGH-level input requirements. Its ±24 mA drive at 3.0 V also exceeds standard TTL fan-out specifications.
Is the TSSOP5 (SOT353-1) package lead-free and RoHS compliant?
Yes. The 74LVC1G79GW-Q100 uses lead-free matte tin terminal finish and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and compliance documentation are available via Nexperia's product change notifications.
