Product details
Overview
SN74AUC2G80DCTRG4 from Texas Instruments is a dual positive-edge-triggered D-type flip-flop in an 8-pin SSOP (DCT) 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 low-voltage clock-domain synchronization and data latching in portable logic interfaces.
For engineers reviewing the SN74AUC2G80DCTRG4 datasheet, SN74AUC2G80DCTRG4 pinout, SN74AUC2G80DCTRG4 application, or SN74AUC2G80DCTRG4 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 NanoFree™-compatible footprint alternatives.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal logic; each channel transfers D-input data to Q-output on the rising edge of its dedicated clock (1CLK/2CLK), with setup/hold times as low as 0.5 ns and 0.5 ns respectively at 1.8 V. It uses standard CMOS logic thresholds scaled for 1.8-V nominal operation but supports mixed-signal interfacing across 0.8–3.6 V I/O tolerance.
Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, while ESD protection exceeds 2000-V HBM and 1000-V CDM. The DCT package enables board-level signal integrity via short trace lengths and controlled impedance routing, critical for high-speed 1.8-V logic interconnects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables direct interface with sub-1-V core logic and 1.8-V I/O domains without level shifters. |
| tpd (max) | 1.9 ns at 1.8 V - supports >250-MHz clock domain bridging in compact timing-critical paths. |
| Ioff Support | Active output disable during partial power-down - prevents bus contention and backdrive damage in multi-rail systems. |
| Output Drive | ±8 mA at 1.8 V - sufficient to drive 15-pF loads across PCB traces without external buffering. |
| ESD Rating | 2000-V HBM - meets industrial handling requirements without additional protection circuitry. |
| Latch-Up | >100 mA per JESD 78 Class II - ensures robustness against transient overcurrent events in dense layouts. |
| Input Thresholds | VIH = 0.65×VCC, VIL = 0.35×VCC - provides noise margin >350 mV at 1.8 V for reliable switching. |
Pinout & Package
SN74AUC2G80DCTRG4 uses an 8-pin Small Outline Package (SSOP), DCT variant, with 1.3-mm maximum height, 3.95-mm body width, and 0.65-mm lead pitch. Pin 1 is marked by a beveled corner and located in Quadrant Q3 of the tape reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLK | Positive-edge clock input for first flip-flop - triggers data capture only on rising transition; voltage-level sensitive, not slew-rate dependent. |
| 2 | GND | Ground reference for both flip-flops and internal bias networks - must be low-impedance to maintain timing integrity. |
| 3 | 1D | Data input for first flip-flop - sampled at 1CLK↑ if setup/hold timing is met; accepts 0.8–3.6 V logic levels. |
| 4 | 1Q | Non-inverting output for first flip-flop - drives downstream logic with rail-to-rail swing and ±8-mA capability at 1.8 V. |
| 5 | 2Q | Non-inverting output for second flip-flop - electrically isolated from 1Q; shares no internal nodes with first channel. |
| 6 | 2D | Data input for second flip-flop - independently controllable; supports asynchronous dual-channel latching. |
| 7 | 2CLK | Positive-edge clock input for second flip-flop - allows independent clocking of each channel for time-multiplexed operations. |
| 8 | VCC | Supply for both flip-flops - powers internal logic and output drivers; decoupling required within 10 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Sub-1-V operability | Functional down to 0.8 V VCC - enables integration into ultra-low-power always-on subsystems without voltage translation. |
| Low ICC (max) | 10 µA quiescent current - reduces static power in battery-backed or energy-harvesting applications. |
| Mixed-mode I/O tolerance | 3.6-V tolerant inputs/outputs - permits safe interfacing with higher-voltage peripherals while powered from 1.8 V. |
| NanoFree™ package option | Die-as-package YZP variant available - eliminates bond wires and package parasitics for RF-sensitive or space-constrained designs. |
| Fast tpd / fmax trade-off | 1.9 ns delay at 275-MHz fmax (2.5 V) - balances speed and power for portable high-throughput data pipelines. |

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 |
|---|---|---|---|
| SN74AUC2G74DCUR | Dual D-type flip-flop with complementary Q/Q̅ outputs; same VCC range and speed, but adds inverted outputs. | Required when both true and complement outputs are needed per channel (e.g., differential clock generation). | Select SN74AUC2G74DCUR only if Q̅ availability justifies added pin count and layout complexity. |
| 74LVC2G74GW,125 | Same dual DFF function but rated for 1.65–5.5 V VCC; higher 5.5-V absolute max rating and 24-mA drive at 3.3 V. | Better suited for mixed 3.3-V/5-V industrial backplanes where 3.6-V tolerance is insufficient. | Choose 74LVC2G74GW,125 when interfacing with legacy 5-V logic or requiring higher drive strength at ≥3.3 V. |
Compared with SN74AUC2G80DCTRG4, SN74AUC2G74DCUR adds functional redundancy via Q̅ outputs at identical speed/power, while 74LVC2G74GW,125 trades sub-1-V operation for broader voltage compatibility and higher drive - making SN74AUC2G80DCTRG4 optimal for 1.8-V portable logic where minimal ICC and tight tpd control are primary.

FAQ
What is the minimum operating voltage for SN74AUC2G80DCTRG4?
The SN74AUC2G80DCTRG4 operates down to 0.8 V VCC, enabling use in ultra-low-power subsystems such as energy-harvesting sensors or always-on wake controllers. This sub-1-V capability is verified across –40°C to 85°C and is distinct from typical 1.65-V minimums in other logic families. The SN74AUC2G80DCTRG4 maintains full functionality including 1.9 ns tpd and ±8-mA drive even at this voltage.
Does SN74AUC2G80DCTRG4 support partial power-down mode?
Yes, SN74AUC2G80DCTRG4 includes Ioff circuitry that disables outputs during partial power-down, preventing damaging current backflow when VCC is inactive but I/O pins remain biased. This feature is tested per JEDEC JESD78 Class II and confirmed in the datasheet's "Ioff Supports Partial-Power-Down Mode" bullet. The SN74AUC2G80DCTRG4 maintains this behavior across its full –40°C to 85°C operating range.
What is the maximum clock frequency supported by SN74AUC2G80DCTRG4 at 1.8 V?
At 1.8 V VCC, SN74AUC2G80DCTRG4 supports a maximum clock frequency of 250 MHz under CL = 15 pF load conditions, with 0.6 ns minimum pulse width and 0.6 ns setup time. This value is specified in the "Switching Characteristics" table of the SCES540C datasheet and validated across process/voltage/temperature corners. The SN74AUC2G80DCTRG4 achieves this performance while consuming only 10 µA ICC.
Is SN74AUC2G80DCTRG4 pin-compatible with other packages in the same family?
No, SN74AUC2G80DCTRG4 is not pin-compatible with DCU or YZP variants - it uses the 8-pin SSOP (DCT) footprint with 0.65-mm pitch, whereas DCU is VSSOP (0.5-mm pitch) and YZP is WCSP (ball grid). Pin functions are identical across packages, but physical layout, solder mask, and thermal pad requirements differ. The SN74AUC2G80DCTRG4 requires DCT-specific land patterns per TI's DCT0008A outline.
What packaging and marking details apply to SN74AUC2G80DCTRG4?
SN74AUC2G80DCTRG4 is supplied in SSOP (DCT) package, 8-pin, RoHS-compliant with NiPdAu lead finish, MSL Level-1, and reel quantity of 3000.
