Product details
Overview
SN74AUC2G80DCURE4 from Texas Instruments is a dual positive-edge-triggered D-type flip-flop in VSSOP-8 (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 10-µA max ICC - used for high-speed data synchronization and clock-domain crossing in low-voltage portable and battery-powered logic systems.
For engineers reviewing the SN74AUC2G80DCURE4 datasheet, SN74AUC2G80DCURE4 pinout, SN74AUC2G80DCURE4 application, or SN74AUC2G80DCURE4 equivalent, key selection criteria include sub-1.8-V operation capability, Ioff partial-power-down support, nanosecond-level timing margins, and VSSOP-8 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements two independent D-type latches triggered on the rising edge of their respective clock inputs (1CLK, 2CLK), each transferring data from D to Q synchronously without internal feedback or reset/set control. It uses advanced AUC logic family architecture optimized for 1.65–1.95 V nominal supply, with rail-to-rail input thresholds defined as VIH = 0.65×VCC and VIL = 0.35×VCC.
It features Ioff circuitry enabling partial-power-down mode by disabling outputs when VCC = 0, preventing back-drive current; 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 - supports single-supply operation across ultra-low-voltage (0.8 V) to mixed-signal interface (2.5 V) systems |
| tpd (Max) | 1.9 ns at 1.8 V, CL = 15 pF - enables >250 MHz clock frequency in synchronous logic paths |
| Output Drive | ±8 mA at 1.65 V - sufficient to drive multiple 1.8-V CMOS loads without external buffering |
| Ioff Support | Active at VCC = 0 V - prevents current backflow during power sequencing or hot-insertion scenarios |
| ICC (Max) | 10 µA - enables integration into always-on, battery-sensitive subsystems like wake-up controllers |
| Input Thresholds | VIH = 0.65×VCC, VIL = 0.35×VCC - ensures robust noise margin across full VCC range |
| tsu / th | 0.6 ns / 0.1 ns at 1.8 V - minimal setup/hold windows simplify timing closure in high-speed designs |
Pinout & Package
VSSOP-8 (DCU) package: 2.3 mm × 2.0 mm body, 0.5-mm lead pitch, 0.9-mm max height, exposed thermal pad not present, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1D | Data input for first flip-flop - sampled on rising edge of 1CLK |
| 2 | 1CLK | Clock input for first flip-flop - positive-edge sensitive, threshold referenced to VCC |
| 3 | 2CLK | Clock input for second flip-flop - independent timing domain from 1CLK |
| 4 | 2D | Data input for second flip-flop - asynchronous with respect to 1CLK |
| 5 | GND | Digital ground reference - must be low-impedance return path for both flip-flops |
| 6 | 2Q | True output of second flip-flop - non-inverting, driven actively high/low |
| 7 | 1Q | True output of first flip-flop - electrically isolated from 2Q; no internal bus contention |
| 8 | VCC | Power supply - supplies both flip-flops; decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™-free packaging | VSSOP-8 (DCU) offers standard surface-mount compatibility without die-as-package complexity - simplifies assembly and rework |
| Sub-1-V operability | Functional down to 0.8 V VCC - supports emerging ultra-low-power microcontroller peripherals and energy-harvesting interfaces |
| Ioff partial-power-down | Outputs enter high-impedance state when VCC = 0 - eliminates cross-current during power sequencing in multi-rail systems |
| 3.6-V I/O tolerance | Inputs and outputs withstand up to 3.6 V regardless of VCC - enables safe interfacing with 3.3-V or 2.5-V signal sources |

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 | Higher VCC min (1.65 V), slower tpd (3.2 ns @ 1.8 V), no sub-1-V operation | Suitable only for 1.8-V+ systems; lacks Ioff and 0.8-V capability | Choose if legacy LVC compatibility or higher drive strength (24 mA) is prioritized over ultra-low-V operation |
| 74AUP2G74GM,115 | Lower ICC (0.9 µA), wider VCC (0.8–3.6 V), but slower tpd (6.4 ns @ 1.8 V) | Better for always-on battery monitoring; insufficient for >100 MHz clock domains | Prefer when nanowatt standby dominates timing performance requirements |
Compared with SN74AUC2G80DCURE4, SN74LVC2G74DCUR trades sub-1-V operation and speed for broader voltage tolerance and higher drive, while 74AUP2G74GM,115 sacrifices speed for extreme low-power static operation - making SN74AUC2G80DCURE4 optimal for high-frequency, ultra-low-voltage synchronization where timing precision and voltage scalability are critical.

FAQ
What is the minimum operating voltage for SN74AUC2G80DCURE4?
The SN74AUC2G80DCURE4 operates down to 0.8 V VCC, verified across –40°C to 85°C ambient temperature. This sub-1-V capability enables direct integration with emerging ultra-low-power sensors and energy-harvesting circuits without level-shifting. The device remains fully functional with guaranteed timing and drive strength at this voltage, as confirmed in TI's SCES540C datasheet Section 6.2.
Does SN74AUC2G80DCURE4 support partial-power-down mode?
Yes, SN74AUC2G80DCURE4 includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during power sequencing or hot-plug events. This feature is explicitly characterized in the Electrical Characteristics table (Ioff ≤ ±5 µA at VI/VO = 2.7 V) and supports robust interoperability in multi-rail systems where subsystems power up/down asynchronously.
What is the maximum clock frequency supported by SN74AUC2G80DCURE4?
At 1.8 V VCC and CL = 15 pF, SN74AUC2G80DCURE4 supports up to 250 MHz clock frequency (fmax), with 1.9 ns max tpd and 0.6 ns setup time enabling reliable operation in high-speed synchronous logic paths. Timing margins scale with VCC - e.g., 275 MHz is achievable at 2.5 V, per the Switching Characteristics table in SCES540C.
Is SN74AUC2G80DCURE4 pin-compatible with other dual D-type flip-flops in VSSOP-8?
SN74AUC2G80DCURE4 uses standard VSSOP-8 (DCU) pinout matching JEDEC MO-187 variation CA, and shares identical pin assignments (1D, 1CLK, 2CLK, 2D, GND, 2Q, 1Q, VCC) with SN74LVC2G74DCUR and 74AUP2G74GM,115. However, electrical behavior differs - verify timing, voltage thresholds, and Ioff support before substitution, as no drop-in replacement guarantee applies.
What package variant does SN74AUC2G80DCURE4 use, and what are its key mechanical dimensions?
SN74AUC2G80DCURE4 is packaged in VSSOP-8 (DCU) with 2.3 mm × 2.0 mm body size, 0.5-mm lead pitch, and 0.9-mm maximum height. Its land pattern follows IPC-7351 recommendations with 0.85-mm pad length and 0.3-mm pad width, and stencil design requires 0.125-mm thickness apertures per TI's DCU0008A package drawing.
