Product details
Overview
SN74LVC1G80DBVRG4 from Texas Instruments is a single positive-edge-triggered D-type flip-flop designed for 1.65V to 5.5V operation, delivering 4.2ns maximum propagation delay at 3.3V, ±24mA output drive, and Ioff-enabled partial-power-down protection. It functions as a synchronous storage element in clock-domain interfacing, data synchronization, and frequency division circuits.
For engineers reviewing the SN74LVC1G80DBVRG4 datasheet, SN74LVC1G80DBVRG4 pinout, SN74LVC1G80DBVRG4 application, or SN74LVC1G80DBVRG4 equivalent, this page provides verified functional identity, SOT-23-5 package mapping, confirmed timing and drive specifications, and validated alternative options for industrial and embedded logic design.
Technical Context
The SN74LVC1G80DBVRG4 implements a CMOS-based positive-edge-triggered D flip-flop with voltage-level clock detection-triggering occurs at defined input thresholds, not dependent on clock slew rate. Its transmission-gate logic architecture enables precise edge-aligned data capture with setup time as low as 1.1ns (at 5.5V) and hold time up to 0.9ns (at 3.3V).
It supports over-voltage tolerant inputs (up to 5.5V regardless of VCC), bidirectional level translation via Ioff, and operates across –40°C to +125°C ambient temperature in the DBV package. The device lacks asynchronous preset/clear, making its initial Q state undefined without external initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - Enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| tpd (max) | 4.2ns at 3.3V, CL = 15pF - Supports >200MHz clock operation in low-capacitance signal paths. |
| Output Drive | ±24mA at 3.3V - Sustains fast edge rates into moderate capacitive loads (e.g., PCB traces, multiple gate inputs). |
| Ioff Leakage | ±10µA max - Ensures safe isolation during partial power-down, preventing back-drive current damage. |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - Allows mixed-supply systems where input signals exceed local rail voltage. |
| Operating Temp | –40°C to +125°C - Qualified for under-hood automotive, industrial control, and telecom infrastructure environments. |
| ESD Rating | HBM ±2000V - Meets JEDEC JS-001 Class 2, supporting robust handling in automated assembly lines. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90mm × 1.60mm footprint with gull-wing leads; thermal resistance RθJA = 357.1°C/W; suitable for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - D | Data input | Asynchronous data source sampled on CLK↑; accepts voltages up to 5.5V regardless of VCC. |
| 2 - CLK | Positive-edge clock input | Edge-triggered at voltage threshold (not slew-rate dependent); minimum pulse width 2.5ns at 1.8V. |
| 3 - GND | Ground reference | Return path for all internal logic and I/O; must be low-impedance to maintain noise margin and timing integrity. |
| 4 - Q | Non-inverting output | CMOS push-pull output; drives high/low with matched strength; supports bus-hold if externally terminated. |
| 5 - VCC | Power supply | Supplies core logic and I/O; requires local 0.1µF bypass capacitor to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction reduces footprint to 2.90mm × 1.60mm while maintaining standard SOT-23 solder profile. |
| Ioff partial-power-down | Outputs enter high-Z when VCC = 0V; prevents back-current flow and protects powered-down subsystems. |
| Over-voltage tolerant inputs | D and CLK accept 0–5.5V signals even when VCC = 1.65V, enabling seamless level translation without external components. |
| Balanced CMOS outputs | ±24mA drive capability at 3.3V ensures consistent rise/fall times and minimizes skew in timing-critical paths. |
| Latch-up immunity | Exceeds 100mA per JESD78 Class II - eliminates risk of destructive latch-up under transient overvoltage conditions. |

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 | Dual D-flip-flop in same SOT-23-5 package; includes complementary Q̅ output; higher ICC (20µA max). | Required when both true and inverted outputs are needed per stage; occupies same board area but doubles channel count. | Select SN74LVC1G74DBVR only if dual-output functionality or dual-latch density is required; otherwise SN74LVC1G80DBVRG4 offers lower quiescent current and simpler routing. |
| 74LVC1G80GW,125 | NXP variant in SC-70-5 package (2.00mm × 1.25mm); identical electrical specs; rated for –40°C to +125°C. | Preferred where smaller footprint is critical and thermal performance permits (RθJA = 371°C/W vs. 357.1°C/W). | Choose 74LVC1G80GW,125 for space-constrained designs; verify thermal derating in high-power-density layouts due to higher junction-to-ambient resistance. |

FAQ
What is the maximum clock frequency supported by the SN74LVC1G80DBVRG4?
The SN74LVC1G80DBVRG4 supports up to 160MHz clock frequency across its full operating temperature range (–40°C to +125°C) at VCC = 1.8V, 2.5V, 3.3V, or 5V, as specified in timing requirements tables. At 3.3V with CL = 15pF, typical fmax exceeds 200MHz due to 4.2ns tpd, though guaranteed operation remains at 160MHz per datasheet limits.
Does the SN74LVC1G80DBVRG4 have asynchronous reset or set functionality?
No, the SN74LVC1G80DBVRG4 does not include asynchronous preset or clear inputs. Its function table confirms that Q retains its previous state (Q₀) when CLK is inactive (X), and output transitions occur only on the positive edge of CLK. External circuitry is required for deterministic initialization.
Can the SN74LVC1G80DBVRG4 operate with a 1.65V supply and still accept 3.3V input signals?
Yes, the SN74LVC1G80DBVRG4 supports over-voltage tolerant inputs: D and CLK accept voltages up to 5.5V regardless of VCC level. At VCC = 1.65V, it reliably samples 3.3V logic signals without damage or level-shifting components, enabling direct interfacing between disparate voltage domains.
What is the purpose of the Ioff feature in the SN74LVC1G80DBVRG4?
The Ioff feature disables all outputs and isolates inputs when VCC = 0V, limiting leakage current to ±10µA. This prevents back-driving of powered-down sections in partial-power-down systems-critical for hot-swap modules, battery-backed subsystems, and multi-rail power sequencing in the SN74LVC1G80DBVRG4.
Is the SN74LVC1G80DBVRG4 pin-compatible with other members of the SN74LVC1Gxx series?
No-pin assignments differ across the SN74LVC1Gxx family. The SN74LVC1G80DBVRG4 uses SOT-23-5 with pinout D-CLK-GND-Q-VCC. In contrast, SN74LVC1G74DBVR places Q̅ on pin 5 and shares pin 4 for Q, while SN74LVC1G00DBVR assigns pins to dual-input NAND logic. Always verify pin configuration per device datasheet.
