Product details
Overview
SN74AUP1G80 from Texas Instruments is a single positive-edge-triggered D-type flip-flop in SC70-5 package, operating from 0.8 V to 3.6 V supply, with 4.4 ns maximum propagation delay at 3.3 V, 0.9 µA maximum ICC, and 1.5 pF typical input capacitance. It serves as a low-power clock-synchronized data latch in battery-powered portable logic interfaces.
For engineers reviewing the SN74AUP1G80 datasheet, SN74AUP1G80 pinout, SN74AUP1G80 application, or SN74AUP1G80 equivalent, key selection criteria include its ultra-low static/dynamic power consumption, Ioff partial-power-down support, Schmitt-trigger input hysteresis (250 mV typ), 3.6-V I/O tolerance, and suitability for point-to-point signal conditioning in space-constrained embedded systems.
Technical Context
The SN74AUP1G80 implements a single D-type register with edge-sensitive clock capture, where data transfer occurs strictly on the positive-going clock transition at a defined voltage threshold-not dependent on clock slew rate. Its CMOS push-pull output stage provides balanced sourcing/sinking capability up to ±4 mA at 3 V.
It features Ioff circuitry enabling high-impedance inputs/outputs during power-down, preventing back-current flow, and includes integrated clamp diodes for ESD protection per JESD22-A114-B (2000-V HBM) and JESD22-C101 (1000-V CDM). The Schmitt-trigger input action (Vhys = 250 mV typ at 3.3 V) improves noise immunity against slow or noisy clock/data edges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface with 1.2-V, 1.8-V, 2.5-V, and 3.3-V logic domains without level shifters |
| Max Propagation Delay (tpd) | 4.4 ns at 3.3 V, CL = 5 pF - supports >200-MHz clock operation in low-load configurations |
| Static Current (ICC) | 0.9 µA max at TA = –40°C to +85°C - extends battery life in always-on sensor nodes and wearables |
| Input Capacitance (Ci) | 1.5 pF typical - minimizes loading on preceding drivers and preserves signal integrity in high-speed routing |
| Ioff Leakage | 0.6 µA max at 0 V supply - ensures safe isolation during partial power-down in multi-rail systems |

Pinout & Package
SN74AUP1G80 is packaged in a 5-pin SC70 (DCK) footprint measuring 1.25 mm × 2.00 mm, optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | 250 mV typical hysteresis at 3.3 V - eliminates chatter from slow-rising clocks or noisy sensor signals |

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 |
|---|---|---|---|
| SN74LVC1G80DBVT | Higher ICC (10 µA max), wider VCC range (1.65–5.5 V), no Schmitt input, no Ioff | Requires external power sequencing; less suitable for partial-power-down or noisy environments | Choose when interfacing with 5-V logic and lower cost is prioritized over ultra-low power or noise immunity |
| 74AHC1G74SE-7 | Single D-type with set/reset, 2.0-V to 5.5-V operation, 7 ns tpd at 3.3 V, no Ioff | Lacks power-down isolation; requires additional reset logic for known initial state | Prefer when deterministic power-on reset behavior is required and board space allows larger SOT-353 package |
Compared with SN74LVC1G80DBVT and 74AHC1G74SE-7, the SN74AUP1G80 uniquely combines sub-µA static current, Schmitt-trigger noise rejection, and Ioff-enabled partial-power-down-making it optimal for energy-critical, space-constrained, and multi-rail embedded systems where reliability under voltage transients matters.

FAQ
What is the minimum supply voltage required for reliable operation of the SN74AUP1G80?
The SN74AUP1G80 is fully specified down to 0.8 V supply voltage across the full industrial temperature range (–40°C to +85°C). At 0.8 V, it maintains functional timing with 20 MHz maximum clock frequency and meets all DC specifications including VIH/VIL thresholds and ICC ≤ 0.9 µA. This enables direct integration with energy-harvesting sources and ultra-low-voltage microcontrollers.
Does the SN74AUP1G80 support partial power-down mode, and how does it behave when VCC = 0 V?
Yes, the SN74AUP1G80 supports partial power-down via its Ioff feature. When VCC = 0 V, both input and output terminals enter a high-impedance state with leakage current limited to 0.6 µA max. This prevents current backflow into powered sections of the system, protecting upstream drivers and ensuring safe hot-swap or multi-rail sequencing-critical in modular power architectures.
Can the SN74AUP1G80 be used as a frequency divider, and what design considerations apply?
Yes, the SN74AUP1G80 can implement a 2:1 frequency divider by connecting Q to D. Since it lacks preset/clear, the initial output state is undefined; an external override circuit (e.g., pull-up/pull-down with enable switch) is recommended for deterministic startup. The 4.4 ns tpd at 3.3 V supports division of clocks up to 260 MHz, but layout must minimize trace capacitance to maintain timing margins.
What is the significance of the Schmitt-trigger input in the SN74AUP1G80, and how does it affect system design?
The Schmitt-trigger input provides 250 mV typical hysteresis at 3.3 V, allowing the SN74AUP1G80 to cleanly interpret slow-rising or noisy clock/data signals without oscillation. This eliminates the need for external RC filters or Schmitt buffers in applications like mechanical switch debouncing or low-frequency sensor interfacing-reducing BOM count and PCB area while improving robustness in electrically noisy environments.
How does the 3.6-V I/O tolerance of the SN74AUP1G80 benefit mixed-voltage system designs?
The SN74AUP1G80 accepts input voltages up to 4.6 V (per Absolute Maximum Ratings) while operating from as low as 0.8 V, enabling direct connection to 3.3-V or 5-V peripherals without level-shifting components. This simplifies interconnect in mixed-voltage systems-such as interfacing a 1.8-V FPGA I/O bank with a 3.3-V sensor interface-while maintaining signal integrity and reducing component count and layout complexity.
