Product details
Overview
SN74AUC2G80DCUR from Texas Instruments is a dual positive-edge-triggered D-type flip-flop in an 8-pin VSSOP (DCU) package, operating from 0.8 V to 2.7 V with 1.9 ns max propagation delay at 1.8 V, ±8-mA output drive, and Ioff support for partial-power-down mode - used in high-speed level-shifting, clock domain crossing, and low-voltage data latching in portable and battery-powered systems.
For engineers reviewing the SN74AUC2G80DCUR datasheet, SN74AUC2G80DCUR pinout, SN74AUC2G80DCUR application, or SN74AUC2G80DCUR equivalent, key selection criteria include sub-1-V operability, 275-MHz max clock frequency at 2.5 V, latch-up immunity >100 mA per JESD 78 Class II, and 10-µA max ICC for ultra-low static power in space-constrained designs.
Technical Context
This device implements two independent D-type flip-flops, each triggered on the rising edge of its dedicated clock input (1CLK, 2CLK), with asynchronous data sampling at D inputs and registered outputs at Q pins. It supports mixed-mode signal operation via 3.6-V I/O tolerance while powered from as low as 0.8 V.
The SN74AUC2G80DCUR integrates Ioff circuitry that disables outputs during power-down to prevent backflow current, and features ESD protection exceeding 2000-V HBM, 200-V MM, and 1000-V CDM - enabling robust interfacing between voltage domains in modern low-power SoC subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables direct integration into 0.9-V/1.2-V/1.8-V logic rails without level shifters. |
| tpd (max) | 1.9 ns at 1.8 V - supports >250-MHz clock domain synchronization in high-speed serial interfaces. |
| Output Drive | ±8 mA at 1.8 V - sufficient to drive 50-Ω transmission lines or fan-out to ≥3 AUC-series loads. |
| Ioff Support | Active at VCC = 0 V - blocks current flow between powered and unpowered sections in hot-plug or sleep-mode systems. |
| ESD Rating | 2000-V HBM - meets industrial-grade robustness requirements for handheld and automotive infotainment modules. |
| Latch-Up | >100 mA per JESD 78 Class II - ensures immunity to transient-induced parasitic thyristor activation. |
| ICC (max) | 10 µA - reduces quiescent power in always-on sensor nodes and real-time clock backup circuits. |
Pinout & Package
VSSOP (DCU) package: 8-pin, 2.0 mm × 1.25 mm body, 0.5-mm pitch, 0.9-mm max height, moisture sensitivity level 1 (260°C peak reflow), RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLK | Positive-edge clock input for first flip-flop - triggers data capture from 1D on rising transition. |
| 2 | 1D | Data input for first flip-flop - sampled at 1CLK↑ if setup/hold times (tsu = 0.6 ns, th = 0.1 ns @ 1.8 V) are met. |
| 3 | 1Q | Non-inverting registered output of first flip-flop - reflects 1D state after 1CLK↑ with tpd ≤ 1.9 ns. |
| 4 | GND | Ground reference for both flip-flops and internal logic - must be low-impedance for noise immunity. |
| 5 | VCC | Supply rail for core logic and I/O - accepts 0.8–2.7 V; powers Ioff circuitry when active. |
| 6 | 2CLK | Positive-edge clock input for second flip-flop - independent timing control enables dual-domain operation. |
| 7 | 2D | Data input for second flip-flop - electrically isolated from 1D path; supports asynchronous dual-channel latching. |
| 8 | 2Q | Non-inverting registered output of second flip-flop - provides matched delay and drive to 1Q for parallel data paths. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction eliminates bond wires and mold compound - reduces parasitic inductance for <2-ns timing integrity. |
| Ioff partial-power-down | Outputs enter high-Z state when VCC = 0 V - prevents back-drive damage in multi-rail systems with staggered power sequencing. |
| Sub-1-V operability | Functional down to 0.8 V VCC - supports energy harvesting and ultra-low-power MCU peripherals without voltage boosting. |
| 3.6-V I/O tolerance | Inputs/outputs withstand up to 3.6 V regardless of VCC - enables safe interfacing with 3.3-V controllers in mixed-voltage FPGA I/O banks. |
| Low dynamic power | Cpd = 1.4 pF at 1.8 V - minimizes switching current in high-frequency clock distribution networks. |

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 |
|---|---|---|---|
| SN74AUP2G80DCUR | Higher VCC min (0.8 V same), but lower max fclock (200 MHz @ 1.8 V vs. 250 MHz); 1.8-V optimized only. | Better suited for ultra-low-power always-on logic where speed <200 MHz suffices and ICC = 0.9 µA is critical. | Choose SN74AUP2G80DCUR only if sub-1-µA ICC outweighs 50-MHz speed loss and system clock stays below 200 MHz. |
| 74LVC2G80GW,115 | Wider VCC range (1.65–5.5 V), higher drive (±24 mA), but slower tpd (3.2 ns @ 3.3 V) and no Ioff. | Required for 5-V legacy interfaces or higher fan-out, but lacks power-down isolation for mixed-rail hot-swap use cases. | Choose 74LVC2G80GW,115 only when interfacing to 5-V logic or driving >5 loads; avoid where Ioff or sub-1.8-V operation is needed. |
Compared with SN74AUC2G80DCUR, SN74AUP2G80DCUR trades speed for ultra-low ICC in always-on sensing, while 74LVC2G80GW,115 sacrifices Ioff and low-voltage capability for broader voltage compatibility and higher drive - making SN74AUC2G80DCUR the optimal choice for 1.8-V high-speed, mixed-domain, and power-gated applications.

FAQ
What is the minimum supply voltage required for functional operation of the SN74AUC2G80DCUR?
The SN74AUC2G80DCUR operates down to 0.8 V VCC across the full –40°C to 85°C temperature range, with guaranteed timing performance (e.g., tpd ≤ 5 ns) and logic functionality validated at this rail. Below 0.8 V, behavior is unspecified and not recommended for production use.
Does the SN74AUC2G80DCUR support true bidirectional data flow?
No, the SN74AUC2G80DCUR is a unidirectional D-type flip-flop with dedicated D inputs and Q outputs - it does not include direction-control logic or bus transceiver functionality. Data flows strictly from D to Q on clock edges; no reverse path exists.
Can the SN74AUC2G80DCUR be used in a 3.3-V system without level shifters?
Yes - while VCC must remain within 0.8–2.7 V, the SN74AUC2G80DCUR inputs and outputs tolerate up to 3.6 V regardless of supply voltage. This allows direct connection to 3.3-V drivers/receivers when powered from 1.8 V, provided VCC is not exceeded.
What is the purpose of the Ioff feature in the SN74AUC2G80DCUR?
The Ioff feature disables all outputs when VCC = 0 V, placing them in high-impedance state to prevent current backflow from live I/O traces into a powered-down section - essential for safe power sequencing in multi-rail FPGAs, PMICs, and hot-pluggable modules using SN74AUC2G80DCUR.
Is the SN74AUC2G80DCUR pin-compatible with other members of the SN74AUC2Gxx series?
No - the SN74AUC2G80DCUR has a unique pinout optimized for dual DFF function (1CLK/1D/1Q/2CLK/2D/2Q/GND/VCC). Other AUC2G devices like SN74AUC2G125 (buffer) or SN74AUC2G74 (dual DFF with preset/clear) use different pin assignments and are not pin-compatible.
