Product details
Overview
74LVC2G74GN,115 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 state-holding circuits in mixed-voltage digital systems.
For engineers reviewing the 74LVC2G74GN,115 datasheet, 74LVC2G74GN,115 pinout, 74LVC2G74GN,115 application, or 74LVC2G74GN,115 equivalent, this device is selected for low-voltage logic sequencing, 3.3 V/5 V bus bridging, edge-sensitive control latching, and space-constrained PCBs requiring XSON8 footprint compatibility and Schmitt-trigger noise immunity.
Technical Context
This flip-flop implements a master-slave D-latch architecture synchronized to the LOW-to-HIGH transition of CP, with independent active-low asynchronous SD and RD that override clocked behavior. Its Schmitt-trigger inputs tolerate slow-rising signals up to 20 ns/V (at VCC = 1.65 V), enabling robust operation with noisy or RC-filtered clocks.
The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and multi-rail system designs. Input overvoltage tolerance to 5.5 V allows direct interfacing with 5 V TTL outputs while powered from 1.65–3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 5.5 V - supports dual-rail translation between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Operating temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| Propagation delay (CP to Q) | 1.0 ns (min) to 4.1 ns (max) at VCC = 4.5–5.5 V - enables >200 MHz clock operation in high-speed control paths |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or moderate capacitive loads without buffering |
| IOFF leakage | ±2 μA max at VCC = 0 V - ensures safe isolation during power sequencing and prevents backfeed into unpowered rails |
| Input hysteresis | Schmitt-trigger action - provides ≥0.3 V hysteresis, rejecting noise on slow edges in motor control or sensor interface lines |
| ESD rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD robustness |
Pinout & Package
XSON8 package (SOT1116): extremely thin small outline, no leads, 8-terminal surface-mount device with 1.2 mm × 1.0 mm × 0.35 mm body dimensions and bottom-side thermal pad (non-electrical).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CP | Clock input - triggers data capture on LOW-to-HIGH edge; Schmitt-triggered for noise immunity |
| 2 | VCC | Positive supply - powers internal logic and output drivers; IOFF active when VCC = 0 V |
| 3 | D | Data input - sampled at CP rising edge if setup/hold times met; tolerant to 5.5 V regardless of VCC |
| 4 | SD | Asynchronous set - forces Q = HIGH, Q̅ = LOW when asserted LOW; overrides clocked operation |
| 5 | GND | Ground reference - return path for all currents; must be low-impedance for stable timing |
| 6 | Q | True output - reflects stored D value after CP edge or SD/RD assertion; CMOS-compatible swing |
| 7 | Q̅ | Complementary output - inverted logic of Q; enables differential signaling or reset-synchronized feedback |
| 8 | RD | Asynchronous reset - forces Q = LOW, Q̅ = HIGH when asserted LOW; priority over SD in simultaneous assertion |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65–5.5 V operation enables drop-in replacement across legacy and modern low-voltage logic families |
| Overvoltage-tolerant inputs | 5.5 V max input voltage regardless of VCC - eliminates external level shifters when interfacing 5 V peripherals |
| IOFF partial power-down | Outputs enter high-impedance state at VCC = 0 V - prevents back-current in hot-plug or multi-supply systems |
| Schmitt-trigger inputs | Input hysteresis rejects noise on slow-rising clock or control signals in electrically noisy environments |
| High noise immunity | CMOS input structure with >40 % noise margin at VCC = 3.3 V - reduces false triggering in industrial PLC I/O modules |

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 |
|---|---|---|---|
| SN74LVC1G74DCKR | Single D-FF in SC70-8 (SOT353); identical VCC range and IOFF, but 2.5 mm × 1.25 mm footprint - 2.5× larger area than SOT1116 | Larger package limits use in ultra-dense portable medical or wearables PCBs where 1.2 mm × 1.0 mm real estate is constrained | Select when SC70 assembly infrastructure exists and thermal dissipation >150 mW is required |
| 74AUP1G74GM,115 | Ultra-low-power variant (AUP family); 0.8–3.6 V VCC, 1.2 μA ICC at 3.3 V - 10× lower static current than LVC, but 6.5 ns max tpd at 3.3 V | Lower speed and narrower voltage range restrict use in 5 V legacy interfaces or >100 MHz clock domains | Select for battery-powered IoT nodes prioritizing energy efficiency over speed or voltage flexibility |
Compared with SN74LVC1G74DCKR and 74AUP1G74GM,115, the 74LVC2G74GN,115 uniquely balances ultra-compact XSON8 size, full 1.65–5.5 V interoperability, and <4.1 ns propagation delay - making it optimal for space- and performance-constrained mixed-voltage control logic.

FAQ
What is the minimum recommended VCC for guaranteed operation at 125 °C?
The 74LVC2G74GN,115 is fully specified down to 1.65 V across -40 °C to +125 °C per Table 7. At 125 °C, VIH remains 0.65VCC (min) for VCC = 1.65–1.95 V, and output drive maintains ±24 mA capability at VCC = 3.0 V. No derating is required below 1.65 V.
Can SD and RD be tied together for combined set/reset functionality?
Yes - connecting SD and RD to the same control line creates a toggle-reset function: asserting LOW sets Q = HIGH, releasing sets Q = LOW on next CP edge. However, simultaneous LOW assertion forces Q = HIGH and Q̅ = HIGH (invalid state), so external logic must ensure only one is active at a time unless intentional reset dominance is designed.
Does the XSON8 package (SOT1116) require solder paste stencil adjustments versus standard QFN?
Yes - SOT1116 has 0.35 mm height and 0.27 mm terminal pitch. Recommended stencil aperture is 0.12 mm thick with 0.25 mm × 0.35 mm openings (80 % area ratio) and nickel-plated walls to prevent bridging. Reflow profile must peak at 260 °C for ≤10 s to avoid voiding under the thermal pad.
How does IOFF behave when VCC is ramping during power-up?
IOFF activates when VCC drops below ~0.8 V and remains active until VCC exceeds ~1.2 V. During ramp-up, outputs stay high-Z until VCC crosses the IOFF disable threshold (~1.2 V), then transition to functional mode. This prevents undefined states or bus contention during brown-out conditions.
