Product details
Overview
74LVC1G74GM,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. It operates from –40 °C to +125 °C and supports mixed-voltage interfacing between 3.3 V and 5 V systems in digital control logic paths.
For engineers reviewing the 74LVC1G74GM,125 datasheet, 74LVC1G74GM,125 pinout, 74LVC1G74GM,125 application, or 74LVC1G74GM,125 equivalent, this device serves as a compact, low-power edge-triggered storage element for clock-synchronized data latching, state retention, and asynchronous control in space-constrained industrial and automotive subsystems.
Technical Context
This flip-flop implements synchronous data capture on the LOW-to-HIGH clock transition, with independent asynchronous active-LOW set and reset that override clocked behavior. Schmitt-trigger inputs tolerate slow-rising signals and improve noise immunity in noisy environments.
The IOFF circuit disables outputs during power-down, preventing backflow current when VCC = 0 V, and overvoltage-tolerant inputs accept up to 5.5 V regardless of supply voltage - enabling robust level translation without external components.
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 |
| Propagation Delay (tpd) | 1.0 ns to 4.1 ns - ensures sub-5 ns timing margin at 5 V for >200 MHz max frequency |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads |
| IOFF Leakage | ±2 μA at VCC = 0 V - prevents damaging back-current during hot-insertion or partial power-down |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets industrial-grade robustness requirements per JS-001/JS-002 |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and extended-temperature industrial use |
| Input Thresholds | VIL ≤ 0.3VCC, VIH ≥ 0.7VCC - compatible with TTL and CMOS logic families across full VCC range |
Pinout & Package
XQFN8 package (SOT902-2): plastic ultra-thin quad flat no-lead, 1.4 × 1.2 × 0.45 mm body, 0.4 mm pitch, wettable flank terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CP | Clock input | Positive-edge-triggered; LOW-to-HIGH transition captures D input into Q register |
| 2 - D | Data input | Synchronous input sampled at CP rising edge; requires 1.0–1.3 ns setup/hold at 3.3 V |
| 3 - Q | True output | Active-HIGH registered output; complements Q̅; drives loads up to ±24 mA |
| 4 - GND | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for signal integrity |
| 5 - Q̅ | Complement output | Active-LOW registered output; provides inverted state for differential signaling or feedback |
| 6 - RD | Asynchronous reset | Active-LOW; forces Q = LOW, Q̅ = HIGH immediately, overriding clock and D |
| 7 - SD | Asynchronous set | Active-LOW; forces Q = HIGH, Q̅ = LOW immediately, overriding clock and D |
| 8 - VCC | Supply voltage | Primary power rail; powers core logic and I/O buffers; supports IOFF when = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65 V to 5.5 V enables drop-in replacement across legacy and modern logic families |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V, eliminating backfeed risk in multi-rail systems |
| Schmitt-trigger inputs | Input hysteresis improves noise margin and allows direct connection to slow or noisy control signals |
| Overvoltage-tolerant I/O | Inputs withstand 5.5 V regardless of VCC - eliminates level-shifter need in mixed-voltage interfaces |
| JEDEC-compliant ESD | HBM >2000 V and CDM >1000 V ensure reliability in automated assembly and field operation |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
|
Use Scenario: Latching sensor status (e.g., door open/closed) in a distributed I/O node with isolated power domains. IC Role / Device Role / Timing Role: Asynchronous set/reset stores fault states independently of main controller clock; edge-triggered D input captures polled sensor updates. Use Value: Enables deterministic state capture under brown-out conditions and eliminates metastability via guaranteed setup/hold margins. |
Use Scenario: Synchronizing wake-up requests from LIN peripherals to a CAN-connected microcontroller in a body domain ECU. IC Role / Device Role / Timing Role: Acts as a clock-domain crossing buffer: LIN-side signal triggers SD/RD, while MCU-side CP aligns event to system clock. Use Value: Prevents race conditions during sleep/wake transitions and reduces software polling overhead through hardware edge detection. |
| Medical Infusion Pump Logic | Test Equipment Signal Conditioning |
|
Use Scenario: Capturing emergency stop button press in a safety-critical infusion pump control path with redundant validation. IC Role / Device Role / Timing Role: Dual-redundant flip-flops (one per channel) store actuated state; Q and Q̅ feed independent watchdog monitors. Use Value: Provides hardware-level fault detection via complementary outputs and supports ISO 13849 PL d compliance through predictable timing. |
Use Scenario: Debouncing mechanical switch inputs and synchronizing them to a 100 MHz test sequencer clock. IC Role / Device Role / Timing Role: Uses Schmitt-trigger inputs to suppress contact bounce; CP edge samples cleaned signal into deterministic timing domain. Use Value: Eliminates FPGA/software debounce logic, reduces BOM count, and guarantees <4.1 ns propagation delay jitter across temperature. |
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 function, SOT-23-6 package; only 6 pins - lacks dedicated Q̅ output (Q̅ derived externally) | Requires external inverter for complement output; higher board area due to added passive | Select when Q̅ is unused or can be synthesized; prefer 74LVC1G74GM,125 when true/complement outputs are both needed in minimal footprint |
| 74AUP1G74GW,125 | Lower VCC range (0.8 V–3.6 V); 1.8 V typical; 30% lower ICC but no 5 V tolerance | Not suitable for 5 V interface or mixed 3.3 V/5 V systems; optimized for ultra-low-power battery operation | Choose 74LVC1G74GM,125 for voltage flexibility and interoperability; select AUP variant only in strictly 1.8 V–3.3 V battery-powered designs |
Compared with SN74LVC1G74DBVR and 74AUP1G74GW,125, the 74LVC1G74GM,125 uniquely delivers full 5 V-tolerant I/O, true/complement outputs in XQFN8, and IOFF support - making it the only option for space-constrained, mixed-voltage, partial-power-down applications requiring guaranteed asynchronous control.

FAQ
Does 74LVC1G74GM,125 support 5 V input signals when powered from 3.3 V?
Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, allowing direct connection to 5 V sources while operating at 3.3 V or even 1.8 V. This eliminates external level shifters in mixed-voltage systems and is verified per datasheet Table 6 and Section 2 features.
What is the minimum pulse width required on CP, SD, or RD inputs?
The minimum CP pulse width is 2.0 ns at VCC = 4.5–5.5 V (Table 9). For SD and RD, minimum pulse width is 1.0 ns at same VCC. These values ensure reliable edge detection and asynchronous assertion across the full –40 °C to +125 °C range and are specified in the Dynamic Characteristics section.
How does the IOFF feature behave during power sequencing?
When VCC drops to 0 V, the IOFF circuit actively disables all outputs, forcing them into high-impedance state regardless of input states. This prevents back-current flow from other powered rails into the unpowered device, protecting system integrity during hot-swap or staggered power-down sequences.
Can 74LVC1G74GM,125 replace older 74HC74 variants in existing designs?
Yes, with qualification. It matches HC74 functionality (edge-triggered D-FF with async set/reset) but offers wider VCC (1.65–5.5 V vs. 2–6 V), lower propagation delay (<4.1 ns vs. ~15 ns), and IOFF. Verify timing margins, especially setup/hold at target VCC, and confirm PCB pad layout matches SOT902-2 XQFN8 footprint.
