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 support. It functions as a synchronous storage element in timing-critical control paths of ADAS sensor interfaces and body control modules.
For engineers reviewing the 74LVC1G74DP-Q100 datasheet, 74LVC1G74DP-Q100 pinout, 74LVC1G74DP-Q100 application, or 74LVC1G74DP-Q100 equivalent, key selection considerations include edge-triggered data capture timing (tsu = 1.1 ns @ 5 V), Schmitt-trigger input tolerance for slow-rising signals, overvoltage-tolerant 5.5 V inputs in mixed-voltage systems, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
This device implements a master-slave D flip-flop architecture with fully asynchronous active-low set and reset controls that override clocked behavior. Its dual-mode operation supports both synchronous data latching on CP rising edges and immediate state forcing via SD/RD independent of clock activity.
The IOFF circuit enables safe bus isolation during partial power-down by disabling outputs when VCC = 0 V, preventing backflow current. Schmitt-trigger inputs provide hysteresis (typ. 0.3 V) to reject noise on slow-transitioning control lines, while overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level - enabling direct interfacing between 3.3 V logic and 5 V peripherals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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 without level shifters. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine compartment and transmission control applications. |
| Propagation Delay (tpd) | 1.0 ns to 4.1 ns - minimum 1.0 ns at 5 V enables reliable operation in >200 MHz clock domains (fmax = 200 MHz). |
| Output Drive Strength | ±24 mA @ VCC = 3.0 V - sufficient to drive multiple LVC loads or small capacitive traces without buffering. |
| Input Hysteresis | Typ. 0.3 V - Schmitt-trigger action rejects noise on slow-rising clock or control signals in noisy automotive environments. |
| IOFF Leakage | ±2 μA @ VCC = 0 V - ensures negligible current flow during system sleep modes, preserving battery life. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - meets stringent automotive ESD immunity requirements for module-level integration. |
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' in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CP | Clock input | Positive-edge-triggered control signal; LOW-to-HIGH transition captures D-input value into flip-flop register. |
| 2 - D | Data input | Synchronous data source; value sampled at CP rising edge if setup/hold times met (tsu = 1.1 ns @ 5 V). |
| 3 - Q | True output | Complementary logic state of stored data; drives downstream logic or feedback paths with ±24 mA capability. |
| 4 - GND | Ground reference | 0 V return path for all internal circuits and I/O; must be low-impedance to maintain noise immunity. |
| 5 - Q̅ | Complement output | Inverted logic state of stored data; enables direct implementation of toggle or JK-like functionality without external inverters. |
| 6 - RD | Asynchronous reset | Active-low forced reset; overrides clock and sets Q = 0, Q̅ = 1 immediately upon assertion, independent of CP. |
| 7 - SD | Asynchronous set | Active-low forced set; overrides clock and sets Q = 1, Q̅ = 0 immediately upon assertion, independent of CP. |
| 8 - VCC | Supply voltage | Primary power rail; powers internal logic and I/O buffers; IOFF activates when VCC = 0 V to isolate outputs. |
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 per JEDEC JESD22 standards. |
| IOFF partial power-down mode | Outputs enter high-impedance state with <±2 μA leakage when VCC = 0 V, enabling safe hot-plug and power-gating in multi-rail systems. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC level (1.65–5.5 V), eliminating need for external clamping diodes in mixed-voltage interconnects. |
| Schmitt-trigger inputs | Provides 0.3 V typical hysteresis on all pins, rejecting noise on slow-rising clock or control signals common in automotive harnesses. |
| Direct TTL interface | VIH = 0.7×VCC and VIL = 0.3×VCC thresholds ensure compatibility with legacy 5 V TTL outputs without level translation. |

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 only; identical pinout and electrical specs otherwise. | Lacks AEC-Q100 qualification; unsuitable for under-hood or safety-critical locations. | Select only for cabin-integrated infotainment or non-safety subsystems where extended temperature range is not required. |
| 74LVC1G74DC-Q100 | VSSOP8 package (SOT765-1); 2.3 mm body width; same die, timing, and qualification as DP variant. | Smaller footprint and lower profile; preferred for space-constrained modules like radar front-ends. | Choose when PCB area is constrained and thermal dissipation permits use of smaller VSSOP8 package. |
Compared with SN74LVC1G74DRYR, the 74LVC1G74DP-Q100 adds automotive qualification and extended temperature range without sacrificing speed or drive strength; compared with 74LVC1G74DC-Q100, it trades compactness for improved thermal performance and handling robustness 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, verified across -40 °C to +125 °C ambient. At lower supply voltages (e.g., 1.65 V), fmax drops to 80 MHz due to reduced switching speed. This rating assumes proper load capacitance (≤30 pF) and clean power delivery with local decoupling.
How does the IOFF feature protect the device during power sequencing?
When VCC = 0 V, the IOFF circuit disables all outputs, limiting leakage current to ±2 μA and preventing backflow current from live buses into the unpowered IC. This avoids latch-up risk and unintended logic state corruption during staggered power-up/down sequences common in multi-rail automotive ECUs.
Can the 74LVC1G74DP-Q100 interface directly with 5 V TTL outputs?
Yes - its inputs are overvoltage tolerant up to 5.5 V and meet TTL-compatible thresholds: VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 2.7 V to 3.6 V. No external level shifter is needed when connecting to standard 5 V TTL drivers, simplifying board design and reducing BOM count.
What is the purpose of Schmitt-trigger inputs on this flip-flop?
Schmitt-trigger inputs provide hysteresis (~0.3 V typical) to reject noise and slow-rising/falling signals commonly found in automotive wiring harnesses. This eliminates false triggering on noisy clock or control lines, ensuring reliable set/reset and data capture even with >10 ns input rise/fall times.
