Product details
Overview
74LVC1G74DP,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 operation, and IOFF partial power-down support. It functions as a synchronous storage element in clock-domain interfacing, level translation, and control logic sequencing - e.g., in industrial I/O modules requiring robust edge-triggered state retention under mixed-voltage conditions.
For engineers reviewing the 74LVC1G74DP,125 datasheet, 74LVC1G74DP,125 pinout, 74LVC1G74DP,125 application, or 74LVC1G74DP,125 equivalent, key selection criteria include its 4.1 ns max propagation delay at 5 V, ±24 mA output drive at 3.0 V, Schmitt-trigger input tolerance for slow-rising signals, IOFF-enabled backflow prevention during power sequencing, 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 that override clocked data capture. Its Schmitt-trigger inputs accept slow-rising waveforms (≤20 ns/V at 1.65 V), enabling direct connection to mechanical switches or noisy sensor interfaces without external conditioning.
The IOFF circuit disables outputs when VCC = 0 V, blocking destructive current flow between powered and unpowered sections in hot-swap or partial-power-down systems. Input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V logic while operating from 1.65 V–3.3 V supplies - critical for voltage-level translation in mixed-supply FPGA/CPU peripheral buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 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 without level shifters. |
| Max Propagation Delay | 4.1 ns at VCC = 4.5–5.5 V - enables reliable operation up to 200 MHz clock frequency in timing-critical control paths. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads (<30 pF) without buffering. |
| IOFF Leakage | ±2 μA at VCC = 0 V - ensures negligible backfeed current during system power sequencing or standby modes. |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - rejects noise on slow-switching inputs (e.g., pushbuttons, encoders) without external RC filtering. |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets industrial IEC 61000-4-2 immunity requirements for board-level handling and field deployment. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC environments. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-lead, 3 mm body width, 0.65 mm pitch, 0.5 mm lead length, 0.5 mm profile - optimized for automated SMT assembly and thermal relief in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CP | Clock input | LOW-to-HIGH edge-triggered; initiates synchronous data capture only on rising transition; Schmitt-triggered for noise immunity. |
| 2 - D | Data input | Stores logic state at Q/Q̅ on next valid CP edge if setup/hold times (1.1 ns min su / 1.0 ns min h at 5 V) are met. |
| 3 - Q | True output | Active HIGH complement of Q̅; delivers stored D value after tpd (max 4.1 ns); drives ±24 mA at 3.0 V. |
| 4 - GND | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance to maintain noise margin and switching integrity. |
| 5 - Q̅ | Complement output | Inverted copy of Q; enables direct implementation of toggle or JK-like behavior without external inverters. |
| 6 - RD | Asynchronous reset | Active LOW; forces Q = LOW / Q̅ = HIGH immediately, overriding CP and D - used for hardware-initiated state clearing. |
| 7 - SD | Asynchronous set | Active LOW; forces Q = HIGH / Q̅ = LOW immediately - essential for known-power-on initialization or fault recovery. |
| 8 - VCC | Supply voltage | Primary power rail; IOFF circuitry activates when VCC = 0 V to disable outputs and prevent back-current into powered subsystems. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65 V–5.5 V operation enables drop-in replacement across legacy 5 V and modern ultra-low-voltage systems without redesign. |
| IOFF partial power-down | Outputs enter high-impedance state when VCC = 0 V, eliminating risk of back-current damage during hot-plug or staged power-up sequences. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V at 3.3 V allows clean latching of slow or noisy signals (e.g., from rotary encoders or limit switches) without external debouncing. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs regardless of VCC level - permits direct connection to 5 V microcontrollers while powered from 1.8 V or 2.5 V rails. |
| JEDEC-compliant ESD | HBM >2000 V and CDM >1000 V meet IPC-A-610 Class 3 handling requirements and reduce field failure risk in manufacturing and end-use. |
Applications

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 lacks RD/SD pins - only synchronous D/Q/Q̅; no asynchronous control. | Cannot perform hardware reset/set; unsuitable for safety-critical or power-on initialization use cases. | Select only when asynchronous control is unnecessary and board space favors SOT-23 over TSSOP8. |
| 74AUP1G74GW,125 | Lower static current (0.9 μA vs. 4 μA), wider temp range (-40 °C to +125 °C same), but slower max speed (130 MHz vs. 200 MHz at 5 V). | Preferred for ultra-low-power battery-operated systems where speed <130 MHz suffices and leakage must be minimized. | Choose when energy efficiency outweighs timing performance, especially in always-on sensor nodes or wearables. |
Compared with SN74LVC1G74DBVR and 74AUP1G74GW,125, the 74LVC1G74DP,125 uniquely balances high-speed operation (200 MHz), full asynchronous control (SD/RD), and mixed-voltage robustness - making it optimal for industrial control, automotive body electronics, and FPGA-adjacent signal conditioning where deterministic reset and level translation are mandatory.

FAQ
Does the 74LVC1G74DP,125 support 1.8 V operation?
Yes - it is fully specified from 1.65 V to 5.5 V. At 1.8 V, it delivers guaranteed tpd ≤13.4 ns, VIH ≥0.65×VCC (≥1.17 V), and VOL ≤0.35×VCC (≤0.63 V), meeting LVC logic thresholds for reliable interoperation with 1.8 V microcontrollers and FPGAs.
Can SD and RD be left unconnected in normal operation?
No - SD and RD are active-low asynchronous inputs with no internal pull-ups. Leaving them floating risks unintended set/reset events due to noise. They must be pulled HIGH via ≥10 kΩ resistors to VCC or driven actively to ensure predictable state initialization and hold behavior.
What is the purpose of the IOFF feature, and how does it behave?
IOFF disables outputs when VCC = 0 V, preventing back-current flow from powered I/O traces into the unpowered IC. Measured IOFF leakage is ≤±2 μA, ensuring safe hot-swap capability and compliance with IEC 61000-4-5 surge protection requirements in modular systems.
How does the Schmitt-trigger input improve system reliability?
Schmitt-trigger inputs provide ~0.3 V hysteresis at 3.3 V, allowing clean transitions even with slow-rising signals (e.g., from RC-filtered switches or long cables). This eliminates contact bounce artifacts and reduces susceptibility to EMI-induced glitches without external components.
