Product details
Overview
74LVC1G74DP-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-grade operation, and IOFF partial power-down protection. It functions as a synchronous storage element in timing-critical control paths of automotive body electronics and ADAS subsystems.
For engineers reviewing the 74LVC1G74DP-Q100 datasheet, 74LVC1G74DP-Q100 pinout, 74LVC1G74DP-Q100 application, or 74LVC1G74DP-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, Schmitt-trigger input tolerance for slow-rising signals, ±24 mA output drive at 3.0 V, propagation delay down to 1.0 ns at 5 V, and TSSOP8 (SOT505-2) package compatibility with high-density PCB layouts.
Technical Context
This device implements a master-slave D flip-flop architecture with fully asynchronous active-low set and reset controls independent of clock edge timing. Its IOFF circuitry disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences in multi-rail automotive ECUs.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust operation with slow or noisy clock/data edges. Input voltage tolerance up to 5.5 V allows direct interfacing with 5 V legacy systems while powered from 3.3 V rails - critical for mixed-voltage domain translation in gateway modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface between 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 under-hood automotive use |
| Propagation Delay (tpd) | 1.0 ns to 4.1 ns - enables reliable operation up to 200 MHz at 5 V, suitable for high-speed control loops |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or small capacitive traces without buffering |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures safe isolation during hot-swap or power sequencing events |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - rejects noise on slow-rising clock or control lines in electrically harsh environments |
| Set-up/Hold Time | tsu = 1.1 ns, th = 1.0 ns at 5 V - tight timing margins compatible with modern microcontroller GPIO toggle rates |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located below marking code "V74".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CP | Clock input | Positive-edge-triggered; LOW-to-HIGH transition captures D-input state; Schmitt-triggered for noise immunity |
| 2 D | Data input | Asynchronous data source; sampled on CP rising edge; overvoltage tolerant to 5.5 V |
| 3 Q | True output | Active HIGH output; complements Q̅; ±24 mA drive capability at 3.0 V |
| 4 GND | Ground reference | 0 V return path; must be low-impedance for stable switching and EMI control |
| 5 Q̅ | Complement output | Logic inverse of Q; enables differential signaling or dual-edge sampling in feedback paths |
| 6 RD | Asynchronous reset | Active LOW; forces Q = LOW, Q̅ = HIGH regardless of CP or D state; priority over clock |
| 7 SD | Asynchronous set | Active LOW; forces Q = HIGH, Q̅ = LOW; higher priority than RD in simultaneous assertion |
| 8 VCC | Supply voltage | Power rail; IOFF circuit activates when VCC = 0 V to disable outputs and block backfeed current |
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 humidity testing |
| IOFF partial power-down mode | Outputs automatically high-impedance when VCC = 0 V, eliminating backflow current in multi-supply systems |
| Overvoltage-tolerant inputs | Accepts 0 V to 5.5 V signals regardless of VCC level - enables 5 V-to-3.3 V level translation without external resistors |
| Schmitt-trigger inputs | Provides >0.3 V hysteresis at 3.3 V, rejecting EMI-induced glitches on long harness-connected control lines |
| Low dynamic power dissipation | CPD = 15 pF at 3.3 V - minimizes switching current in battery-sensitive always-on vehicle networks |

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 | Non-automotive grade; rated -40 °C to +85 °C; no AEC-Q100 qualification; identical pinout and electrical specs | Not approved for under-hood or safety-critical automotive use; suitable only for consumer or industrial prototypes | Select only if AEC-Q100 compliance is not required and cost is primary constraint |
| 74LVC1G74DC-Q100 | VSSOP8 (SOT765-1) package; 2.3 mm body width; same electrical specs and AEC-Q100 Grade 1 rating | Higher density footprint; requires tighter trace routing; lower thermal resistance than TSSOP8 | Prefer for space-constrained PCBs where thermal performance exceeds TSSOP8 requirements |
Compared with SN74LVC1G74DRYR, the 74LVC1G74DP-Q100 provides guaranteed automotive reliability and extended temperature operation; compared with 74LVC1G74DC-Q100, it offers easier assembly and slightly better thermal margin in TSSOP8 form factor.

FAQ
What is the maximum clock frequency supported by the 74LVC1G74DP-Q100?
The device supports up to 200 MHz maximum clock frequency at VCC = 4.5 V to 5.5 V, with propagation delay as low as 1.0 ns. At lower supply voltages (e.g., 1.65 V to 1.95 V), fmax drops to 80 MHz due to increased tpd. These values are validated across the full -40 °C to +125 °C operating range per AEC-Q100 test conditions.
Does the 74LVC1G74DP-Q100 support level shifting between 5 V and 3.3 V logic domains?
Yes - its inputs tolerate up to 5.5 V regardless of VCC level, and it operates from 1.65 V to 5.5 V. When powered at 3.3 V, it accepts 5 V input signals directly without external components, making it suitable for bidirectional level translation in mixed-voltage automotive gateways and sensor hubs.
How does the IOFF feature protect the device during partial power-down?
When VCC = 0 V, the IOFF circuit disables all outputs, placing them in high-impedance state. This prevents backflow current from live I/O lines into the unpowered device, avoiding latch-up or damage during hot-swap, power sequencing, or sleep-mode transitions in multi-rail automotive ECUs.
Can the 74LVC1G74DP-Q100 replace older 74HC or 74HCT series flip-flops in automotive designs?
Yes - it matches pinout and function of legacy 74HC1G74/74HCT1G74 but adds AEC-Q100 Grade 1 qualification, wider supply range (1.65–5.5 V), IOFF, and Schmitt-trigger inputs. Direct replacement is possible if layout accommodates TSSOP8 (SOT505-2) and timing margins account for faster propagation delays.
