Product details
Overview
74LVC1G74DC,125 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 operating temperature, and VSSOP8 (SOT765-1) package. It functions as a synchronous storage element in digital control logic, clock-domain interfacing, and state-holding circuits in mixed-voltage systems.
For engineers reviewing the 74LVC1G74DC,125 datasheet, 74LVC1G74DC,125 pinout, 74LVC1G74DC,125 application, or 74LVC1G74DC,125 equivalent, this device supports voltage translation between 3.3 V and 5 V logic domains, features Schmitt-trigger inputs for noise immunity, includes IOFF partial power-down protection, delivers ±24 mA output drive at 3.0 V, and meets JEDEC JESD8-7/5/B standards.
Technical Context
This flip-flop implements edge-triggered synchronous data capture on the LOW-to-HIGH clock transition, with priority-governed asynchronous set and reset that override clocked operation. Its dual-rail input tolerance (up to 5.5 V) and IOFF circuitry enable safe operation during partial power-down states in multi-rail systems.
The device uses CMOS technology with Schmitt-trigger inputs to tolerate slow signal edges, supports propagation delays as low as 1.0 ns (at VCC = 4.5–5.5 V), and maintains guaranteed setup (1.1 ns min) and hold (1.0 ns min) timing across its full voltage and temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (tpd) | 1.0 ns to 4.1 ns - Ensures sub-5 ns timing margin for high-speed control paths up to 200 MHz maximum clock frequency. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to directly drive multiple 74LVC inputs or small capacitive loads without buffering. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Prevents backflow current during hot-insertion or partial power-down sequences. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows 5 V signals to be safely applied while VCC is at 1.8 V or 2.5 V. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive, industrial motor control, and extended-temperature embedded applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets robustness requirements for automated assembly and field-replaceable modules. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8 leads, 2.3 mm body width, 0.5 mm lead length, gull-wing leads, pin 1 index in lower-left corner below marking code "V74".
| 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 state. |
| 2 - D | Data input | Synchronous data source; value sampled only when CP transitions and setup/hold times are met. |
| 3 - Q | True output | Complements RD/SD asynchronous control and reflects stored D value after CP edge. |
| 4 - GND | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for noise immunity. |
| 5 - Q̅ | Complement output | Inverted mirror of Q; enables direct implementation of toggle or JK-like behavior without external inversion. |
| 6 - RD | Asynchronous reset | Active-LOW direct override; forces Q = LOW, Q̅ = HIGH regardless of CP or D state. |
| 7 - SD | Asynchronous set | Active-LOW direct override; forces Q = HIGH, Q̅ = LOW regardless of CP or D state. |
| 8 - VCC | Supply voltage | Primary power rail; powers internal logic and output drivers; supports wide-range operation from 1.65 V to 5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | 1.65 V to 5.5 V operation enables interoperability across legacy and modern logic families without external translators. |
| IOFF partial power-down | Automatic output disable when VCC = 0 V prevents damaging back-current in hot-swap or multi-rail sequencing scenarios. |
| Schmitt-trigger inputs | Input hysteresis rejects noise and accommodates slow rise/fall times (e.g., from RC networks or long traces). |
| Overvoltage-tolerant inputs | Inputs withstand 5.5 V regardless of VCC level - critical for mixed-supply bus interfacing and level-shifting applications. |
| JEDEC-compliant standards | Meets JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8-B/JESD36 (2.7–3.6 V) for assured interoperability. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Latching sensor status (e.g., door open/closed, seatbelt buckle) in distributed I/O nodes with limited PCB space. IC Role / Device Role / Timing Role: Stores and holds asynchronous sensor events until polled by main controller; provides glitch-free edge detection via SD/RD. Use Value: Eliminates need for external debounce circuitry and reduces firmware polling overhead through hardware-level state retention. | Use Scenario: Managing window lift/mirror fold sequencing where precise timing and fail-safe reset are required. IC Role / Device Role / Timing Role: Synchronizes microcontroller commands with motor driver enable signals; RD/SD ensure known start/stop states on power-up or fault recovery. Use Value: Guarantees deterministic initial state and prevents unintended actuator motion during brown-out or reset conditions. |
| USB-C Power Delivery Negotiation | Medical Infusion Pump Logic |
Use Scenario: Capturing handshake bits from USB PD PHY during voltage-level negotiation between 3.3 V MCU and 5 V PD controller. IC Role / Device Role / Timing Role: Voltage-translating D-flip-flop synchronizing cross-domain control signals with sub-5 ns delay and no metastability risk. Use Value: Enables reliable, low-latency handshaking without dedicated level shifters or FPGA logic resources. | Use Scenario: Implementing safety-critical interlocks (e.g., "door closed AND syringe detected" before pump activation). IC Role / Device Role / Timing Role: Dual-rail latch holding validated sensor conditions; Q/Q̅ outputs feed redundant monitoring circuits for SIL-2 compliance. Use Value: Provides hardware-enforced state persistence and output redundancy, reducing software validation burden for IEC 62304 Class C devices. |
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 |
|---|---|---|---|
| SN74LVC1G74DBVR | SOT23-6 package (6-pin), no Q̅ output - only true Q available; same electrical specs and timing. | Limited to single-output use cases; cannot support differential signaling or self-resetting logic without external inverter. | Select when board space is extremely constrained and complement output is unnecessary. |
| 74AUP1G74GW,125 | Lower static current (0.9 μA vs. 4 μA), wider temp range (-40 °C to +125 °C), but reduced drive (±4 mA at 3.0 V). | Better suited for ultra-low-power battery-operated systems; insufficient drive for fanout >2 or capacitive loads >15 pF. | Select when power budget dominates over speed or drive strength, e.g., wearable sensor nodes. |
Compared with SN74LVC1G74DBVR and 74AUP1G74GW,125, the 74LVC1G74DC,125 uniquely balances full dual-output capability, ±24 mA drive, and VSSOP8 footprint - making it optimal for space-constrained industrial control where signal integrity and fanout matter.

FAQ
Does the 74LVC1G74DC,125 support 1.8 V operation?
Yes. The device is fully specified from 1.65 V to 5.5 V, including 1.8 V operation. At VCC = 1.8 V, VIH is 0.65 × VCC (1.17 V min), VIL is 0.35 × VCC (0.63 V max), and tpd is 13.4 ns max across -40 °C to +125 °C, meeting JESD8-7 compliance.
What happens to outputs during power-down (VCC = 0 V)?
When VCC = 0 V, the IOFF circuitry disables both Q and Q̅ outputs, limiting leakage current to ±2 μA max. This prevents back-current flow from driven buses into the unpowered device - essential for hot-swap and partial-power-down system architectures.
Can SD and RD be used simultaneously?
No. Asserting both SD and RD LOW results in an invalid output state (Q = Q̅ = HIGH), which violates the functional definition. The datasheet specifies this condition as undefined; designers must ensure mutual exclusion via external logic or timing control.
Is the VSSOP8 package RoHS and REACH compliant?
Yes. Nexperia confirms SOT765-1 (VSSOP8) packaging for 74LVC1G74DC,125 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound per Nexperia's product compliance documentation.
