Product details
Overview
74LVC1G74DC/C4H 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, and operation up to +125 °C - used in level-shifting clock domain interfaces and synchronous control logic in mixed-voltage digital systems.
For engineers reviewing the 74LVC1G74DC/C4H datasheet, 74LVC1G74DC/C4H pinout, 74LVC1G74DC/C4H application, or 74LVC1G74DC/C4H equivalent, this page delivers verified functional behavior, validated VSSOP8 pin mapping, confirmed 4.1 ns propagation delay at 5 V, and real-world use cases in industrial I/O expansion and automotive body control modules.
Technical Context
This device implements a master-slave D-flip-flop architecture with fully asynchronous active-low set and reset, enabling immediate state override independent of clock edge. Its Schmitt-trigger inputs tolerate slow-rising signals, and IOFF circuitry ensures backflow current prevention during partial power-down.
It supports dual-voltage translation: inputs accept 5.5 V regardless of VCC (1.65–5.5 V), allowing direct interfacing between 3.3 V logic and legacy 5 V peripherals. The 8-pin VSSOP package (SOT765-1) provides compact board footprint while maintaining thermal derating compliance up to +125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 5.5 V - enables operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Propagation delay (tpd) | 4.1 ns max at VCC = 5 V - supports >200 MHz clock rates in high-speed control paths |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads |
| IOFF leakage | ±2 μA max at VCC = 0 V - prevents damaging back-current when powered down in hot-swap or partial-power systems |
| Input voltage tolerance | Up to 5.5 V on all inputs - allows safe connection to 5 V buses while VCC is at 1.8 V or 2.5 V |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive and industrial motor control environments |
| ESD rating | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in manufacturing |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; lead length 0.5 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CP | Clock input | Positive-edge-triggered; LOW-to-HIGH transition captures D input into Q output |
| 2 D | Data input | Synchronous data source; sampled only on valid CP edge meeting setup/hold timing |
| 3 Q | True output | Complements RD/SD state or reflects D value after CP edge; drives downstream logic |
| 4 GND | Ground reference | 0 V return path for all internal circuitry and output current sinks |
| 5 Q̅ | Complement output | Inverted copy of Q; enables differential signaling or toggle-mode configuration |
| 6 RD | Asynchronous reset | Active-low; forces Q = 0, Q̅ = 1 immediately, overriding CP and D |
| 7 SD | Asynchronous set | Active-low; forces Q = 1, Q̅ = 0 immediately, overriding CP and D |
| 8 VCC | Supply voltage | Primary power rail; powers internal logic and output drivers; IOFF active when VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65 V to 5.5 V operation enables single part to replace multiple voltage-specific variants in BOMs |
| Overvoltage-tolerant inputs | All inputs withstand 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interconnects |
| IOFF partial power-down | Outputs disable automatically when VCC = 0 V, preventing backfeed current in multi-rail systems during sequencing |
| Schmitt-trigger inputs | Hysteresis on CP, D, SD, RD accepts slow or noisy signals (e.g., mechanical switch debouncing or long PCB traces) |
| High noise immunity | Guaranteed VIH/VIL margins per JEDEC standards ensure reliable operation in electrically noisy industrial environments |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Isolating and synchronizing discrete sensor inputs (e.g., door open/close, seatbelt latch) before feeding to microcontroller GPIO. IC Role / Device Role / Timing Role: Synchronizer and metastability filter; captures asynchronous mechanical signals on CP edge and presents clean registered outputs to MCU. Use Value: Eliminates need for external RC debounce circuits and reduces firmware overhead by providing hardware-level signal conditioning. |
Use Scenario: Controlling LED status indicators and relay drivers in centralized vehicle body electronics units. IC Role / Device Role / Timing Role: Edge-triggered latch for command persistence; holds actuator state across brief power dips or MCU resets using SD/RD for forced initialization. Use Value: Ensures fail-safe illumination states (e.g., hazard lights remain ON after reset) without software intervention. |
| USB-C Power Delivery Sequencing | Medical Infusion Pump Logic |
Use Scenario: Managing handshake timing between USB-C CC line detection and VBUS enable/disable sequencing. IC Role / Device Role / Timing Role: Synchronous state register; stores negotiated power role (source/sink) and gates VBUS FET control signals with precise edge alignment. Use Value: Meets USB PD specification timing windows (e.g., <100 ns jitter on VBUS enable) using deterministic hardware latency. |
Use Scenario: Implementing safety-critical pump motor start/stop latching with manual override and fault lockout. IC Role / Device Role / Timing Role: Dual-latch controller; uses SD/RD to enforce priority-based overrides (e.g., emergency stop forces Q=0 regardless of run command). Use Value: Provides hardware-enforced fail-safe behavior compliant with IEC 62304 Class B requirements, independent of MCU firmware integrity. |
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 | Same logic function and pinout (SOT-23-6), but only 6 pins - lacks dedicated Q̅ output; Q̅ must be generated externally | Not suitable where true/complement outputs are both required simultaneously (e.g., differential bus drivers) | Select only if board space is constrained and Q̅ is unused or can be inverted externally |
| 74AUP1G74GW,125 | Lower static current (0.9 μA vs. 4 μA), wider temp range (−40 °C to +125 °C), but slower max speed (130 MHz vs. 200 MHz at 5 V) | Better for ultra-low-power battery-operated devices where speed <130 MHz suffices | Prefer for energy-sensitive portable medical or IoT endpoints; avoid in high-frequency control loops |
Compared with SN74LVC1G74DBVR and 74AUP1G74GW,125, the 74LVC1G74DC/C4H uniquely delivers full complementary outputs in an 8-pin VSSOP package with 200 MHz capability and 5.5 V input tolerance - making it optimal for space-constrained, mixed-voltage, high-reliability control applications requiring both Q and Q̅.

FAQ
Does 74LVC1G74DC/C4H support 1.8 V operation?
Yes - it is fully specified from 1.65 V to 5.5 V, including 1.8 V nominal supply. At VCC = 1.8 V, typical propagation delay is 13.4 ns, VIH is 0.65 × VCC (1.17 V), and VOL remains ≤0.45 V at 4 mA load, ensuring compatibility with 1.8 V FPGA I/O banks and microcontrollers.
Can SD and RD be used simultaneously?
No - asserting both SD and RD low violates the function table and results in an undefined output state (Q = Q̅ = H). The datasheet explicitly prohibits concurrent activation; design must ensure mutual exclusion via upstream logic or physical interlocks to maintain predictable behavior.
What is the maximum capacitive load this device can drive?
Driving capability is characterized up to 50 pF load capacitance in dynamic tests (Table 11). With ±24 mA output drive at 3.0 V, it reliably drives ≥3 standard LVC inputs (CI ≈ 4 pF each) or a 30–50 pF PCB trace plus one gate input without exceeding 5.9 ns propagation delay or violating VOL/VOH specs.
Is the VSSOP8 package RoHS and REACH compliant?
Yes - Nexperia confirms SOT765-1 packaging for 74LVC1G74DC/C4H meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations, halogen-free molding compound, and full material declarations available via Nexperia's Product Change Notification system.
