Product details
Overview
SN74LVC2G80DCURG4 from Texas Instruments is a dual positive-edge-triggered D-type flip-flop in an 8-pin VSSOP (DCU) package, supporting 1.65-V to 5.5-V operation with 4.2 ns max propagation delay at 3.3 V, 10 μA max ICC, and Ioff for live insertion. It serves as a compact, low-power data synchronization and storage element in high-speed digital interfaces and clock-domain crossing circuits.
For engineers reviewing the SN74LVC2G80DCURG4 datasheet, SN74LVC2G80DCURG4 pinout, SN74LVC2G80DCURG4 application, or SN74LVC2G80DCURG4 equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases, and confirmed alternative parts - all aligned to TI's SCES309F revision F specification and production-grade DCU packaging.
Technical Context
This device integrates two independent D-type flip-flops sharing no internal logic coupling; each triggers strictly on the rising edge of its dedicated clock input (1CLK/2CLK), with data sampled only when setup and hold times are met. Its Ioff circuitry actively disables outputs during partial power-down, blocking current backflow when VCC = 0 V.
The SN74LVC2G80DCURG4 operates across –40°C to 125°C with rail-to-rail input tolerance (VI up to 5.5 V) and output swing (VO from 0 to VCC), enabling mixed-voltage interfacing without level shifters. Its NanoFree™-derived VSSOP package uses the silicon die as the mechanical structure, minimizing parasitic inductance and thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without external translation. |
| tpd (max) | 4.2 ns at VCC = 3.3 V, CL = 15 pF - enables reliable operation up to 160 MHz clock frequency in synchronous data paths. |
| ICC (max) | 10 μA - ensures ultra-low static power draw suitable for battery-backed or always-on subsystems. |
| Ioff | ±10 μA at VI/VO = 5.5 V, VCC = 0 V - prevents damaging back-drive current during hot-swap or partial-power-down sequences. |
| tsu / th | 0.9 ns / 0.6 ns at VCC = 5.5 V - tight timing margins allow integration into high-speed control loops with minimal skew overhead. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements for board-level handling and field deployment. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and telecom infrastructure applications. |
Pinout & Package
VSSOP (DCU) package: 8-pin, 2.0 mm × 1.25 mm body, 0.5-mm pitch, 0.9-mm max height, exposed pad not present, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLK | Positive-edge clock input for first flip-flop; triggers Q update only on rising transition meeting voltage-level threshold, not edge slew rate. |
| 2 | 1D | Data input for first flip-flop; sampled at 1CLK↑ if held stable for ≥0.9 ns before and ≥0.6 ns after edge (at 5.5 V). |
| 3 | 1Q | Non-inverting output of first flip-flop; driven actively high/low; supports 24 mA sink/source at 3 V. |
| 4 | GND | Digital ground reference for both flip-flops and internal bias networks; must be low-impedance for noise immunity. |
| 5 | 2CLK | Positive-edge clock input for second flip-flop; electrically isolated from 1CLK; identical timing behavior. |
| 6 | 2D | Data input for second flip-flop; independent of 1D; allows dual-channel asynchronous sampling. |
| 7 | 2Q | Non-inverting output of second flip-flop; fully buffered; exhibits <0.8 V ground bounce at 3.3 V per TI test conditions. |
| 8 | VCC | Supply rail for both flip-flops; powers internal logic and output drivers; accepts 1.65–5.5 V with monotonic performance scaling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent DFFs | Two fully isolated flip-flops share only VCC/GND; enable parallel data capture without cross-talk or shared timing constraints. |
| Ioff partial-power-down | Outputs enter high-impedance state with ≤10 μA leakage when VCC = 0 V, permitting safe live insertion into powered backplanes. |
| NanoFree™ VSSOP | Die-as-package construction reduces footprint by 40% vs. standard SOIC-8 and cuts trace inductance for cleaner signal integrity. |
| Rail-to-rail I/O | Inputs tolerate 0–5.5 V regardless of VCC; outputs swing 0–VCC - eliminates need for external level translators in mixed-supply systems. |
| Low ground bounce | Typical VOLP < 0.8 V at VCC = 3.3 V, TA = 25°C - minimizes switching noise coupling into analog sections or adjacent digital channels. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G74DCUR | Single D-type flip-flop with set/reset; lacks second channel and has different pinout (6-pin). | Suitable only for single-channel sync; requires redesign for dual-path use. | Select only when space-constrained single-DFF functionality suffices and layout reuse is not required. |
| 74LVC2G80GW,125 | NXP variant in SC-88 (TSOP-6) package; same logic function but 6-pin, non-pin-compatible; max tpd = 4.7 ns at 3.3 V. | Requires PCB redesign due to different pin count, pitch, and footprint; lower ESD rating (1500-V HBM). | Consider only if sourcing diversity is prioritized over drop-in replacement and thermal performance is secondary. |
Compared with SN74LVC2G80DCURG4, SN74LVC2G74DCUR provides half the channel count in smaller area but cannot replace dual-path functionality, while 74LVC2G80GW,125 offers functional equivalence at higher propagation delay and reduced ruggedness - neither is pin-compatible, requiring layout changes and revalidation.

FAQ
What is the maximum clock frequency supported by the SN74LVC2G80DCURG4?
The SN74LVC2G80DCURG4 supports a maximum clock frequency of 160 MHz across its full operating voltage range (1.65 V to 5.5 V) and temperature range (–40°C to 125°C), as verified in TI's SCES309F datasheet under switching characteristics with CL = 15 pF. This rating holds irrespective of VCC level, enabled by consistent internal timing architecture.
Does the SN74LVC2G80DCURG4 support partial power-down operation?
Yes, the SN74LVC2G80DCURG4 implements Ioff circuitry that disables all outputs when VCC = 0 V, limiting Ioff leakage to ±10 μA. This feature permits safe live insertion into powered systems and prevents back-driving damage - a key requirement for modular backplane architectures and hot-swap applications.
What is the pin compatibility status between SN74LVC2G80DCURG4 and SN74LVC2G80DCTRG4?
SN74LVC2G80DCURG4 (VSSOP-8, DCU) and SN74LVC2G80DCTRG4 (SSOP-8, DCT) share identical logic functionality and pin numbering (1CLK, 1D, 1Q, GND, 2CLK, 2D, 2Q, VCC), but differ in physical dimensions, pitch (0.5 mm vs. 0.65 mm), and thermal profile. They are functionally interchangeable but require PCB footprint redesign due to non-mechanical compatibility.
Can the SN74LVC2G80DCURG4 operate with a 1.8-V supply and still meet timing specifications?
Yes, the SN74LVC2G80DCURG4 is fully specified at 1.8 V ±0.15 V, delivering 3.0 ns typical tpd and maintaining 160 MHz fmax with tsu = 2.2 ns and th = 1.6 ns. All AC and DC parameters in the SCES309F datasheet include explicit 1.8-V test conditions, confirming robust low-voltage operation.
Is the SN74LVC2G80DCURG4 RoHS compliant and what is its moisture sensitivity level?
Yes, SN74LVC2G80DCURG4 is RoHS compliant with NiPdAu lead finish and carries JEDEC MSL Level-1 (unlimited floor life at ≤30°C/60% RH), per TI's PACKAGE OPTION ADDENDUM. Its VSSOP (DCU) package requires no baking prior to reflow, simplifying manufacturing flow for high-reliability assembly.
