Product details
Overview
74LVC1G74GT-Q100 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous set (SD) and reset (RD) inputs, complementary Q and Q̅ outputs, 1.65 V to 5.5 V supply range, -40 °C to +125 °C automotive temperature rating, and XSON8 (SOT833-1) package. It functions as a synchronous storage element in timing-critical control logic, such as clock-domain synchronization or signal edge capture in ADAS sensor interface modules.
For engineers reviewing the 74LVC1G74GT-Q100 datasheet, 74LVC1G74GT-Q100 pinout, 74LVC1G74GT-Q100 application, or 74LVC1G74GT-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, IOFF-enabled partial power-down capability, Schmitt-trigger input tolerance for slow-rising signals, and guaranteed 4.1 ns max propagation delay at 5 V.
Technical Context
This device implements a master-slave D flip-flop architecture with independent asynchronous active-low set and reset controls that override clocked data behavior. Its IOFF circuitry disables outputs when VCC = 0 V, preventing backflow current during power sequencing - critical for mixed-voltage automotive subsystems.
All inputs feature Schmitt-trigger action, enabling robust operation with input rise/fall times up to 20 ns/V (at 1.65 V) or 10 ns/V (at 5.5 V), and overvoltage tolerance to 5.5 V allows direct interfacing between 3.3 V logic and 5 V peripherals without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single D-type flip-flop with asynchronous set/reset, positive-edge clock trigger |
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and powertrain applications |
| Max Propagation Delay | 4.1 ns at VCC = 4.5–5.5 V - enables reliable operation up to 200 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 | ±2 μA at VCC = 0 V - ensures safe hot-insertion and partial power-down in modular ECUs |
| Input Hysteresis | Schmitt-trigger inputs - tolerates slow or noisy signals without false triggering |
Pinout & Package
XSON8 plastic extremely thin small outline package (SOT833-1), 1.0 mm × 1.95 mm × 0.5 mm body, no leads, 8 terminals, wettable flank design for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RD | Asynchronous reset input | Active-LOW; forces Q = 0, Q̅ = 1 independently of clock - used for system initialization or fault recovery |
| SD | Asynchronous set input | Active-LOW; forces Q = 1, Q̅ = 0 independently of clock - enables deterministic startup state | VCC | Positive supply rail | 1.65–5.5 V; powers internal logic and output buffers; IOFF activates when VCC = 0 V |
| Q | True output | Complementary to Q̅; driven actively high/low; ±24 mA drive at 3 V supports fanout ≥ 10 LVC gates |
| Q̅ | Complement output | Inverted version of Q; enables direct connection to enable/disable logic without external inverters |
| D | Data input | Samples on LOW-to-HIGH CP transition; requires 1.1 ns setup / 1.0 ns hold time at 5 V |
| CP | Clock input | Edge-sensitive; only responds to rising edge; Schmitt-triggered for noise immunity on long PCB traces |
| GND | Ground reference | 0 V return path; must be low-impedance to maintain switching integrity and EMI performance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and HTOL stress |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V, eliminating backfeed current in multi-rail power architectures |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V signals regardless of VCC setting - eliminates need for external level translators in mixed-supply systems |
| Schmitt-trigger inputs | Provides >0.3 V hysteresis on all pins - suppresses chatter from slow edges or EMI-coupled noise on harness-connected lines |
| ESD robustness | HBM >2000 V, CDM >1000 V - meets stringent automotive board-level ESD requirements per ISO 10605 |
Applications
| ADAS Camera Interface Synchronization | Electric Power Steering (EPS) Fault Latch |
|---|---|
Use Scenario: Capturing frame-valid strobes from CMOS image sensors operating at different voltage domains (e.g., 1.8 V sensor, 3.3 V MCU). IC Role / Device Role / Timing Role: D flip-flop synchronizes asynchronous pixel clock domain transitions into the main processor clock domain while preserving edge alignment. Use Value: Prevents metastability-induced image corruption by providing sub-5 ns setup/hold margins and Schmitt-triggered input filtering on noisy camera harness lines. | Use Scenario: Latching critical fault conditions (e.g., motor phase loss, torque sensor failure) in EPS control units until diagnostic reset. IC Role / Device Role / Timing Role: Asynchronous set/reset flip-flop stores fault state independently of main CPU clock, ensuring persistence during brown-out or reset sequences. Use Value: IOFF protection prevents latch corruption during 12 V battery dip events; AEC-Q100 qualification guarantees reliability over 15-year vehicle lifetime. |
| Body Control Module (BCM) Wake-Up Signal Edge Detection | Infotainment System I²C Bus Glitch Filter |
Use Scenario: Detecting valid door-handle proximity pulses in BCMs where mechanical switch bounce and RF interference cause false wake-ups. IC Role / Device Role / Timing Role: Positive-edge-triggered DFF samples debounced wake signal synchronized to internal 32 kHz RTC clock. Use Value: Schmitt-trigger inputs reject <100 ns noise spikes; 1.65 V min VCC allows direct integration with ultra-low-power RTC domains. | Use Scenario: Filtering spurious I²C START/STOP condition glitches caused by ESD transients on infotainment display cables. IC Role / Device Role / Timing Role: Flip-flop acts as a synchronous edge filter - only passes transitions aligned with clean system clock, discarding asynchronous noise. Use Value: Overvoltage-tolerant inputs withstand 5.5 V transients without clamping diode conduction; 4.1 ns tpd ensures minimal latency in real-time bus arbitration. |
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 |
|---|---|---|---|
| SN74LVC1G74DRYR | TI part in YF package (DSBGA6); lacks AEC-Q100 qualification; max temp +85 °C | Not suitable for under-hood or transmission-control applications requiring Grade 1 | Select only for non-automotive industrial or consumer designs with lower reliability demands |
| 74LVC1G74DP-Q100 | TSSOP8 (SOT505-2) package; 3 mm body width; leaded; 0.65 mm pitch | Better manual handling and reworkability; higher thermal resistance than XSON8 | Prefer for prototyping, low-volume assembly, or legacy PCBs with TSSOP footprints |

FAQ
Does 74LVC1G74GT-Q100 support 1.2 V supply operation?
No. The absolute minimum supply voltage is 1.65 V per the Recommended Operating Conditions table. Operation below this threshold risks undefined logic states, increased static current, and potential latch-up. The device is not characterized or guaranteed for 1.2 V use, even if some units may function intermittently.
Can SD and RD be tied together and driven as a single reset/set line?
Yes, but only if the combined signal is asserted exclusively as either set or reset - never both simultaneously. Driving SD and RD low together violates the function table (results in invalid Q/Q̅ = H/H), causing metastability. Use an external OR gate or dedicated control logic to ensure mutual exclusivity.
What is the maximum capacitive load the outputs can drive reliably?
The outputs are characterized up to 50 pF load capacitance in dynamic testing (Table 11). For reliable 200 MHz operation, keep total load ≤30 pF including PCB trace capacitance. Exceeding this increases propagation delay variation and may cause timing violations in high-speed interfaces.
Is the XSON8 package compatible with standard reflow profiles for lead-free soldering?
Yes. The SOT833-1 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1), allowing unlimited floor life and compatibility with standard Pb-free reflow profiles peaking at 260 °C. Its wettable flanks support automated optical solder-joint inspection.
