Product details
Overview
SN74AUP1G80DBVRG4 from Texas Instruments is a single positive-edge-triggered D-type flip-flop in 5-pin SOT-23 (DBV) package, operating from 0.8 V to 3.6 V supply, with maximum propagation delay of 4.4 ns at 3.3 V, 0.9 µA max ICC, and 4.3 pF typical Cpd - used for clock domain synchronization and frequency division in ultra-low-power portable systems.
For engineers reviewing the SN74AUP1G80DBVRG4 datasheet, SN74AUP1G80DBVRG4 pinout, SN74AUP1G80DBVRG4 application, or SN74AUP1G80DBVRG4 equivalent, key selection criteria include its Ioff-enabled partial-power-down capability, Schmitt-trigger input hysteresis (250 mV typ), 3.6-V I/O tolerance for mixed-voltage interfacing, and verified operation down to –40°C for industrial edge nodes.
Technical Context
This device implements a synchronous edge-triggered storage element where data at D transfers to Q only on the positive-going clock transition, independent of clock rise time due to voltage-level–based triggering. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining low noise (<10% VCC overshoot/undershoot).
The integrated Ioff circuit disables outputs during power-down, blocking current backflow, and Schmitt-trigger action on inputs enables robust operation with slow or noisy clock signals - critical for battery-powered sensor nodes interfacing with mechanical switches or RC oscillators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC 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 |
| tpd Max | 4.4 ns at 3.3 V - enables reliable 260-MHz clock operation in point-to-point timing paths |
| ICC Max | 0.9 µA - extends battery life in always-on IoT endpoints by minimizing static power draw |
| Cpd Typ | 4.3 pF at 3.3 V - reduces dynamic switching energy and EMI in high-frequency clock distribution |
| Input Hysteresis | 250 mV typical at 3.3 V - rejects noise up to ±125 mV on clock or data lines without external filtering |
| Ioff Leakage | 0.2 µA max at 0 V VCC - prevents bus contention and backpowering in multi-rail systems during partial shutdown |
| ESD Rating | 2000-V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
SN74AUP1G80DBVRG4 uses the 5-pin SOT-23 (DBV) package, measuring 1.60 mm × 2.90 mm, with exposed pad not present and standard lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D | Data input | Asynchronous data source synchronized to CLK edge; requires setup/hold timing compliance per voltage |
| CLK | Positive-edge clock input | Triggers transfer on rising voltage threshold - not dependent on slew rate; supports Δt/Δv ≤ 200 ns/V |
| GND | Ground reference | Return path for all internal logic and I/O; must be low-impedance to maintain signal integrity |
| Q | Non-inverting output | Edge-aligned replica of D state; capable of driving light capacitive loads (≤15 pF) at full speed |
| VCC | Power supply | Single-supply rail powering core logic and I/O; supports 3.6-V tolerant inputs when VCC = 3.3 V or lower |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | 250 mV typical hysteresis improves noise immunity for slow-switching clocks from microcontrollers or RC networks |
| Ioff partial-power-down | Outputs enter high-Z when VCC = 0 V, preventing backdrive damage in hot-swap or multi-rail power sequencing |
| 3.6-V I/O tolerance | Accepts 3.6-V inputs while powered from 1.8-V or 2.5-V rails - eliminates need for external level translators |
| NanoStar™ packaging | Die-as-package construction reduces parasitic inductance/capacitance for cleaner edge fidelity in high-speed routing |
| Low Ci (1.5 pF) | Minimizes loading on upstream drivers and eases PCB trace impedance matching in dense layouts |
Applications
| Home Automation Sensor Hub | Industrial PLC I/O Module |

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), wider VCC range (1.65–5.5 V), no Schmitt input, no Ioff | Requires external level shifting for sub-1.65 V operation; unsuitable for partial-power-down systems | Select when interfacing with 5-V legacy peripherals and lowest static power is not required |
| 74AHC1G74SE-7 | Single D-type with set/reset, 2.0–5.5 V VCC, 8 ns tpd at 3.3 V, no Ioff or Schmitt input | Lacks power-down safety and noise immunity; requires separate reset initialization | Choose when asynchronous reset functionality is mandatory and system operates above 2.0 V |

FAQ
What is the maximum clock frequency supported by SN74AUP1G80DBVRG4 at 1.8 V?
At 1.8 V ± 0.15 V and TA = –40°C to +85°C, SN74AUP1G80DBVRG4 supports up to 240 MHz with CL = 5 pF load. Performance degrades to 160 MHz at CL = 15 pF and 133 MHz at CL = 30 pF - confirming its suitability for high-speed point-to-point clock forwarding in compact designs where SN74AUP1G80DBVRG4 is deployed.
Does SN74AUP1G80DBVRG4 have a reset or clear function?
No, SN74AUP1G80DBVRG4 does not include asynchronous preset or clear inputs. Its function table shows Q retains its prior state (Q0) when CLK is inactive, and initial output state is undefined after power-up. System-level initialization must be handled externally - for example, via an override switch or MCU-controlled pull-up/down, as documented in the SN74AUP1G80DBVRG4 typical application circuit.
Can SN74AUP1G80DBVRG4 be used as a frequency divider?
Yes - SN74AUP1G80DBVRG4 can implement a 2× frequency divider by connecting Q to D. On each positive CLK edge, the output toggles, halving the input frequency. This configuration is explicitly validated in TI's application note and leverages SN74AUP1G80DBVRG4's edge-triggered behavior and low propagation delay for stable division without added logic.
Is SN74AUP1G80DBVRG4 compatible with 1.2-V supply systems?
Yes, SN74AUP1G80DBVRG4 is fully specified from 0.8 V to 3.6 V, including operation at 1.2 V ± 0.1 V. At this voltage, it achieves 175 MHz fmax (CL = 5 pF), 3.2 ns tpd typical, and maintains Ioff functionality - making SN74AUP1G80DBVRG4 ideal for modern ultra-low-voltage SoC interfaces where power efficiency is paramount.
What is the purpose of the NC pin on SN74AUP1G80DBVRG4 in DBV package?
The fifth pin (Pin 5) on SN74AUP1G80DBVRG4 in the DBV (SOT-23) package is labeled NC (No Internal Connection). It is electrically unconnected and must be left floating or tied to GND for mechanical stability - it serves no functional role in SN74AUP1G80DBVRG4 operation and is not bonded internally.
