Product details
Overview
74LVC2G74DP-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 automotive body electronics and ADAS domain controllers.
For engineers reviewing the 74LVC2G74DP-Q100 datasheet, 74LVC2G74DP-Q100 pinout, 74LVC2G74DP-Q100 application, or 74LVC2G74DP-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, and dual-voltage interface capability between 3.3 V and 5 V logic domains.
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 during power-down to prevent backflow current, enabling safe hot-insertion in multi-rail automotive subsystems.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), allowing reliable operation with noisy or slow-transitioning control signals. The device complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36 across its full voltage range, ensuring interoperability with legacy TTL and modern low-voltage CMOS systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications |
| Propagation Delay (tpd) | 1.0 ns to 4.1 ns - enables reliable operation up to 200 MHz at 5 V, critical for high-speed control loops |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple 74LVC inputs or small capacitive loads (≤30 pF) |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents damaging back-current when powered down in mixed-supply systems |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - rejects noise on asynchronous SD/RD lines in electrically harsh vehicle environments |
| Set-up/Hold Time | tsu = 1.1 ns, th = 1.0 ns at VCC = 5.5 V - tight timing margins enable integration into fast clock domains without added delay buffers |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CP | Clock input | Positive-edge-triggered; LOW-to-HIGH transition captures D input; Schmitt-triggered for noise immunity |
| 2 - D | Data input | Asynchronous data source; sampled only on valid CP edge; overvoltage tolerant to 5.5 V |
| 3 - Q | True output | Active-HIGH registered output; drives loads up to ±24 mA; IOFF disables output when VCC = 0 V |
| 4 - GND | Ground reference | 0 V return path for all internal circuitry and I/O; must be low-impedance for stable timing |
| 5 - Q̅ | Complement output | Inverted version of Q; enables direct implementation of toggle or JK-like behavior without external inversion |
| 6 - RD | Asynchronous reset | Active-LOW; forces Q = LOW, Q̅ = HIGH immediately, overriding clock and data |
| 7 - SD | Asynchronous set | Active-LOW; forces Q = HIGH, Q̅ = LOW immediately, overriding clock and data |
| 8 - VCC | Supply voltage | Primary power rail; powers core logic and I/O; IOFF circuitry monitors this pin to disable outputs during power loss |

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 | Single DFF, same pinout (SOT-5X3), but rated only to +85 °C and not AEC-Q100 qualified | Restricted to industrial or consumer applications; lacks automotive reliability validation and extended temperature support | Select only for non-automotive designs where cost is prioritized over qualification and thermal margin |
| 74LVC2G74DC-Q100 | Identical electrical specs and AEC-Q100 Grade 1 rating, but in VSSOP8 (SOT765-1) package: 2.3 mm body width, 0.5 mm pitch | Enables higher PCB density in space-constrained modules (e.g., radar sensors); requires tighter placement accuracy | Choose for miniaturized automotive modules where footprint reduction outweighs TSSOP8's assembly robustness |
Compared with SN74LVC1G74DRYR, the 74LVC2G74DP-Q100 provides guaranteed operation at +125 °C and formal AEC-Q100 compliance-critical for powertrain and chassis systems-while versus 74LVC2G74DC-Q100, it trades board area for improved manufacturability and thermal dissipation in TSSOP8 form.

FAQ
What is the maximum clock frequency supported by the 74LVC2G74DP-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 voltages (e.g., 1.65 V), fmax drops to 80 MHz due to reduced drive strength and increased tpd. These values are validated across the full -40 °C to +125 °C operating range per AEC-Q100 test conditions.
Does the 74LVC2G74DP-Q100 support mixed-voltage operation between 3.3 V and 5 V domains?
Yes - its inputs tolerate up to 5.5 V regardless of VCC setting (1.65 V to 5.5 V), enabling direct connection to 5 V sources while powered from 3.3 V. Outputs swing rail-to-rail within the VCC range, allowing clean interfacing with downstream 3.3 V logic without external level shifters or resistive dividers.
How does the IOFF feature protect the device during partial power-down?
When VCC = 0 V, the IOFF circuitry disables both Q and Q̅ outputs, placing them in high-impedance state. This prevents reverse current flow from live system buses (e.g., 5 V CAN lines or 3.3 V sensor interfaces) into the unpowered IC, eliminating risk of latch-up or damage during sleep modes or power sequencing faults.
Can the 74LVC2G74DP-Q100 be used as a standalone debouncer for mechanical switch inputs?
No - while Schmitt-trigger inputs improve noise immunity, the device lacks built-in metastability hardening or programmable delay for switch debouncing. It requires an external RC filter or dedicated debounce controller to meet automotive switch debounce requirements (typically >10 ms). Its role is synchronous latching-not asynchronous filtering.
