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 max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and Ioff support for partial-power-down mode - used for clock division, data synchronization, and low-power edge-sensitive latching in portable electronics.
For engineers reviewing the SN74AUP1G80 datasheet, SN74AUP1G80 pinout, SN74AUP1G80 application, or SN74AUP1G80 equivalent, this page delivers verified electrical specs, validated SC70-5 pin mapping, confirmed timing behavior across voltage/temperature, and real-world use cases in battery-powered automation and signal integrity–sensitive interfaces.
Technical Context
The SN74AUP1G80 implements a synchronous edge-triggered storage element where data transfers from D to Q only on the rising edge of CLK, independent of input slew rate due to voltage-level–based triggering. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining low dynamic power (Cpd = 4.3 pF typical).
It features Schmitt-trigger–enhanced noise immunity (Vhys = 250 mV typical at 3.3 V), 3.6-V I/O tolerance for mixed-voltage interfacing, and Ioff circuitry that disables outputs during power-down to prevent backflow current - enabling safe hot-insertion and multi-rail system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - supports 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 - enables reliable operation up to 260 MHz clock frequency in point-to-point configurations. |
| Input Capacitance (Ci) | 1.5 pF typical - minimizes loading on preceding drivers and preserves signal integrity in high-speed routing. |
| Ioff Leakage Current | 0.6 µA max at –40°C to +85°C - ensures robust isolation during partial power-down, preventing bus contention or leakage-induced state corruption. |
| Static Supply Current (ICC) | 0.9 µA maximum - extends battery life in always-on sensor nodes and ultra-low-power IoT endpoints. |
| Hysteresis Voltage (Vhys) | 250 mV typical at 3.3 V - rejects slow or noisy clock/data transitions, eliminating false triggering in industrial control environments. |
Pinout & Package
SN74AUP1G80DCKR uses the 5-pin SC70 (SOT-353) package, measuring 1.25 mm × 2.00 mm, with exposed pad not present and no thermal slug. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D | Data input | Asynchronous data source synchronized to CLK edge; must meet setup/hold timing (e.g., tsu = 0.4 ns min at 3.3 V) to avoid metastability. |
| CLK | Clock input | Positive-edge–sensitive trigger; voltage-level–driven (not edge-rate–dependent), enabling robust operation with slow-rising clocks. |
| GND | Ground reference | Return path for all internal logic and I/O; requires low-inductance connection to minimize ground bounce in high-speed switching. |
| Q | Non-inverted output | Edge-aligned replica of D sampled at CLK↑; drives downstream loads up to ±4 mA while maintaining rail-to-rail swing. |
| VCC | Power supply | Single-supply input supporting 0.8–3.6 V; powers internal logic and I/O buffers; bypassing with 0.1 µF ceramic capacitor is mandatory. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA max enables >10-year battery life in coin-cell–powered wearables and remote sensors. |
| 3.6-V tolerant I/O | Allows direct connection to 3.3-V peripherals even when VCC = 1.8 V, simplifying mixed-voltage board design. |
| Schmitt-trigger input hysteresis | Vhys = 250 mV typical improves noise margin by >2× versus standard CMOS inputs in factory-floor EMI environments. |
| Ioff partial-power-down | Disables outputs at VCC = 0 V, blocking current flow between powered/unpowered rails - critical for hot-swap backplane applications. |
| NanoStar™ packaging | SC70 footprint reduces PCB area by 40% vs. SOT-23, enabling high-density layout in space-constrained modules like smart meters. |
Applications
| Industrial Sensor Node Timing | Low-Power Clock Division |

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 |
|---|---|---|---|
| SN74LVC1G80DBVR | Higher ICC (10 µA typ), narrower VCC range (1.65–5.5 V), no Ioff, no Schmitt input | Not suitable for partial-power-down systems or noisy 1.2 V/1.8 V domains | Choose only if operating exclusively at ≥3.3 V with no power-gating requirements. |
| 74AHC1G74SE-7 | Single D-flip-flop with set/reset, higher Cpd (12 pF), 2.0–5.5 V operation, no Ioff | Lacks power-down safety; unsuitable for battery-backed or hot-plug systems | Select when asynchronous preset/clear is required and mixed-voltage tolerance is not needed. |
Compared with SN74LVC1G80DBVR and 74AHC1G74SE-7, SN74AUP1G80DCKR uniquely combines sub-µA static current, 0.8 V minimum supply, Ioff, and Schmitt-trigger noise immunity - making it the only viable option for energy-harvesting sensors and multi-rail portable designs demanding guaranteed power-down isolation and robust timing.

FAQ
What is the minimum supply voltage for reliable operation of SN74AUP1G80DCKR?
The SN74AUP1G80DCKR operates reliably down to 0.8 V, as specified in the Recommended Operating Conditions table. At this voltage, it maintains functional timing (fclock ≥ 20 MHz, tpd ≤ 17.2 ns) and logic thresholds (VIH = VCC, VIL = 0 V), enabling compatibility with emerging 0.9 V–1.1 V process nodes and deeply discharged Li-ion cells. This capability is unique to the AUP family among TI's single-gate logic offerings.
Does SN74AUP1G80DCKR support true bidirectional I/O or bus-hold functionality?
No, SN74AUP1G80DCKR does not support bidirectional I/O or bus-hold. It is a unidirectional D-type flip-flop with dedicated input (D, CLK), output (Q), and power terminals (VCC, GND). Bus-hold is absent; external pull-up/down resistors are required if floating inputs must be avoided. The device relies on proper PCB layout and system-level termination rather than internal hold circuitry.
Can SN74AUP1G80DCKR be used in a toggle configuration without external components?
Yes, SN74AUP1G80DCKR can be configured as a toggle flip-flop by connecting Q to D, but a series resistor (≥10 kΩ) is required on the feedback path per TI Application Note SCBA004 to prevent contention during power-up or metastable states. Without it, the output may oscillate or latch unpredictably due to simultaneous drive from Q and undefined D initialization.
How does the Ioff feature of SN74AUP1G80DCKR behave during power sequencing?
When VCC drops below 0.2 V, the Ioff circuitry actively disables both input and output buffers, limiting leakage to ≤0.6 µA. This prevents current backflow from powered downstream logic into the unpowered SN74AUP1G80DCKR, protecting against latch-up and ensuring predictable power-down behavior in multi-rail systems with staggered supply sequencing - a requirement verified in TI's JESD78 Class II latch-up testing.
Is SN74AUP1G80DCKR pin-compatible with other SC70-5 logic devices like SN74AUC1G80?
SN74AUP1G80DCKR shares the same SC70-5 pinout (D–CLK–GND–Q–VCC) with SN74AUC1G80, but they are not functionally interchangeable due to differing VCC ranges (AUC: 0.8–2.7 V vs. AUP: 0.8–3.6 V) and absence of Ioff/Schmitt features in AUC. Layout reuse is possible, but system-level validation of timing, voltage tolerance, and power-down behavior is mandatory before substitution.
