Product details
Overview
74LVC1G74GD,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, ±24 mA output drive at 3.0 V, and IOFF partial power-down protection-used in level translation and synchronous logic control in mixed-voltage digital systems.
For engineers reviewing the 74LVC1G74GD,125 datasheet, 74LVC1G74GD,125 pinout, 74LVC1G74GD,125 application, or 74LVC1G74GD,125 equivalent, this device supports critical timing-critical functions including clock-domain interfacing, metastability mitigation in FPGA I/O bridges, and robust state storage in automotive body controllers where overvoltage tolerance and Schmitt-trigger input noise immunity are required.
Technical Context
This flip-flop operates synchronously on the LOW-to-HIGH clock transition, with data latched only when setup (1.1 ns min at 5 V) and hold (1.0 ns min) timing requirements are met. Asynchronous SD and RD inputs override clocked behavior and assert Q/Q̅ within 4.1 ns (max) at 5 V, enabling immediate state initialization or fault recovery.
The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down-essential for hot-swap and multi-rail system designs. Schmitt-trigger inputs tolerate slow rise/fall times and provide high noise immunity across its full −40 °C to +125 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters |
| Max Clock Frequency | 200 MHz at 5 V - supports high-speed sampling and pipeline staging in real-time control loops |
| Propagation Delay (CP→Q) | 4.1 ns max at 5 V - ensures tight timing margins in sub-10 ns synchronous paths |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - drives multiple LVC loads or short PCB traces without buffering |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents destructive backfeed in powered-down subsystems |

Key Features
| Feature | Design Value |
|---|---|
| Wide voltage operation | 1.65–5.5 V supply allows use as bidirectional level translator between 1.8 V and 5 V domains |
| IOFF partial power-down | Outputs disabled at VCC = 0 V, eliminating backflow current in multi-supply systems |
| Schmitt-trigger inputs | Input hysteresis rejects noise on slow-rising clock or control signals in noisy industrial environments |
| Overvoltage-tolerant inputs | Withstands 5.5 V inputs regardless of VCC - simplifies interconnection with legacy 5 V peripherals |
| High ESD robustness | HBM > 2000 V and CDM > 1000 V reduce field failure risk during assembly and handling |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|

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 | SOT-23-6 package (6-pin); lacks RD pin - reset implemented externally or omitted | Not suitable for designs requiring independent asynchronous reset; limited to single-set or clock-gated reset schemes | Select only if board space permits larger SOT-23 footprint and reset functionality is handled elsewhere |
| 74AUP1G74GM,115 | Lower ICC (0.9 μA typical), 0.8–3.6 V supply, 3.7 ns max tpd at 3.3 V - optimized for ultra-low-power battery operation | Better suited for always-on sensor nodes than high-speed control; not rated for 5 V or 125 °C | Prefer for energy-constrained portable devices; avoid in automotive or industrial thermal environments |
Compared with SN74LVC1G74DBVR and 74AUP1G74GM,115, the 74LVC1G74GD,125 uniquely combines 5 V tolerance, full SD/RD control, and 125 °C qualification in a 1.2 mm × 1.0 mm XSON8 package-making it the only choice for compact, thermally demanding, mixed-voltage automotive and industrial logic interfaces.

FAQ
What is the minimum setup time required for reliable operation at 3.3 V?
At VCC = 3.3 V, the minimum D-to-CP setup time (tsu) is 1.3 ns (typical) and 1.3 ns (max) across −40 °C to +125 °C. This value is verified per JEDEC JESD8-B and applies to standard load conditions (CL = 50 pF, RL = 500 Ω). No derating is needed for industrial temperature operation.
Can 74LVC1G74GD,125 be used with a 1.8 V supply and 3.3 V inputs?
Yes. Inputs are overvoltage tolerant up to 5.5 V regardless of VCC, so 3.3 V signals may safely drive SD, RD, CP, or D when VCC = 1.8 V. Output VOH will be ~1.7 V (min) under 4 mA load, compatible with 1.8 V LVC receivers.
Does the IOFF feature require external pull-up/down resistors?
No. The IOFF circuit internally disables output buffers when VCC = 0 V, presenting high-impedance outputs without external components. This behavior is specified with ±2 μA max leakage at VI = 5.5 V and VCC = 0 V, per Table 10 in the datasheet.
Is the XSON8 package (SOT996-2) compatible with standard reflow profiles?
Yes. The SOT996-2 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its 0.35 mm profile and wettable flanks ensure compatibility with automated optical inspection and standard Type 3 solder paste printing.
