Product details
Overview
SN74AUC1G80DCKRG4 from Texas Instruments is a single positive-edge-triggered D-type flip-flop in SC-70 (DCK) 5-pin package, designed for ultra-low-voltage operation (0.8 V to 2.7 V), delivering ±8-mA output drive at 1.8 V and 1.9 ns max propagation delay. It supports mixed-mode signal interfacing in portable logic, level-shifting buffers, and clock-domain synchronization circuits.
For engineers reviewing the SN74AUC1G80DCKRG4 datasheet, SN74AUC1G80DCKRG4 pinout, SN74AUC1G80DCKRG4 application, or SN74AUC1G80DCKRG4 equivalent, key selection criteria include sub-1-V operability, Ioff partial-power-down support, 1.9 ns tpd at 1.8 V, ±8-mA drive strength, and SC-70 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a synchronous edge-triggered storage element with setup/hold timing referenced to the rising clock edge, independent of input slew rate. Its CMOS design enables rail-to-rail output swing and supports bidirectional voltage translation between 0.8-V and 2.7-V domains.
The integrated Ioff circuitry disables outputs during power-down, preventing back-current flow when VCC = 0 V, while latch-up performance exceeds 100 mA per JESD 78 Class II. ESD protection meets 2000-V HBM, 200-V MM, and 1000-V CDM standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - Enables direct interface with sub-1-V logic rails and backward compatibility with 1.8-V systems. |
| tpd (max) | 1.9 ns at 1.8 V - Supports >250-MHz clock frequencies in high-speed data capture paths. |
| Ioff Support | Active at VCC = 0 V - Allows safe insertion into live backplane or hot-swap bus environments without damaging current flow. |
| Output Drive | ±8 mA at 1.8 V - Sufficient to drive two 10-pF loads with <1.9 ns skew, eliminating need for external buffers. |
| ICC (max) | 10 µA - Enables battery-powered applications with multi-year standby life in always-on sensor nodes. |
| tsu / th | 0.6 ns / 0.1 ns at 1.8 V - Tight timing margins simplify high-frequency register-to-register path closure in FPGA companion logic. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D (Data Input) | Asynchronous data input sampled on CLK rising edge; accepts 0.8–2.7 V logic levels with no level-shifter required. |
| 2 | GND | Ground reference for all internal circuitry and output drivers; must be low-impedance connection to minimize ground bounce. |
| 3 | CLK | Positive-edge-sensitive clock input; triggering threshold is voltage-based, not slew-rate dependent. |
| 4 | VCC | Single supply rail powering both core logic and output stage; supports dynamic voltage scaling down to 0.8 V. |
| 5 | Q (Output) | Non-inverted registered output; actively driven high/low with ±8-mA capability at 1.8 V. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction reduces parasitic inductance/capacitance, enabling clean 1.9 ns switching in dense layouts. |

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 |
|---|---|---|---|
| SN74AUP1G80DBVR | Higher ICC (20 µA max), slower tpd (2.5 ns at 1.8 V), same SC-70 package. | Better noise immunity (higher VIH/VIL thresholds), lower speed margin. | Select when system-level noise rejection outweighs timing-critical throughput needs. |
| 74LVC1G80GW,125 | Wider VCC range (1.65–5.5 V), higher drive (±24 mA), larger SOT353 (5-pin) package. | Supports 3.3-V/5-V legacy interfaces but consumes more power and occupies 30% more board area. | Select when interoperability with 3.3-V peripherals is required and board space permits larger footprint. |
Compared with SN74AUC1G80DCKRG4, SN74AUP1G80DBVR trades speed and power for noise margin, while 74LVC1G80GW,125 sacrifices size and efficiency for broad voltage compatibility - making SN74AUC1G80DCKRG4 optimal for compact, battery-powered 1.8-V systems demanding minimal latency and leakage.
