Product details
Overview
SN74LVC1G80DBVRE4 from Texas Instruments is a single positive-edge-triggered D-type flip-flop designed for 1.65V to 5.5V VCC operation, delivering 4.2ns maximum propagation delay at 3.3V, ±24mA output drive, and Ioff support for partial-power-down mode - used in clock frequency division, data synchronization, and edge-sensitive control logic within compact digital systems.
For engineers reviewing the SN74LVC1G80DBVRE4 datasheet, SN74LVC1G80DBVRE4 pinout, SN74LVC1G80DBVRE4 application, or SN74LVC1G80DBVRE4 equivalent, this page provides verified functional identity, SOT-23-5 package mapping, timing behavior across voltage/temperature, Ioff-enabled power sequencing capability, and real-world implementation guidance for clock division and level-shifting interfaces.
Technical Context
The SN74LVC1G80DBVRE4 implements a standard CMOS D-flip-flop architecture with voltage-level–based clock triggering - independent of input rise time - enabling robust edge detection under varying signal slew rates. Its transmission-gate–based logic diagram confirms true positive-edge sampling without internal metastability mitigation circuitry.
It supports bidirectional voltage translation: inputs tolerate up to 5.5V regardless of VCC, while outputs swing rail-to-rail (0V to VCC) and maintain specified drive strength (±24mA at 3.3V) across 1.65V–5.5V supply range. Ioff disables all I/Os during VCC = 0V, preventing back-drive current and enabling hot-insertion in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| tpd (max) | 4.2ns at VCC = 3.3V, TA = –40°C to +85°C, CL = 15pF - supports >200MHz clock operation in high-speed data paths. |
| IOH/IOL | ±24mA at VCC = 3.3V - drives moderate capacitive loads (e.g., multiple gate inputs or short PCB traces) without external buffers. |
| Ioff | ±10µA max at VCC = 0V - ensures safe isolation during power sequencing or partial system shutdown. |
| tsu/th | 1.3ns setup / 0.9ns hold at VCC = 3.3V - tight timing window compatible with modern MCU GPIO and FPGA clock networks. |
| Input Voltage Range | 0V to 5.5V - accepts 5V-tolerant signals even when powered from 1.8V, simplifying mixed-voltage board design. |
| ICC (max) | 10µA - ultra-low static power ideal for battery-powered or always-on subsystems. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90mm × 1.60mm footprint with gull-wing leads; optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - D | Data input | Asynchronous data source sampled on CLK↑; must meet tsu/th relative to clock edge. |
| 2 - CLK | Positive-edge-triggered clock | Voltage-level–sensitive input; triggering occurs at ~VCC/2, not dependent on dV/dt. |
| 3 - GND | Ground reference | Return path for all internal logic and I/O currents; requires low-impedance connection to system ground plane. |
| 4 - Q | Non-inverting output | Edge-aligned replica of D state post-clock transition; capable of sourcing/sinking ±24mA. |
| 5 - VCC | Power supply | Single supply rail supporting 1.65V–5.5V; requires local 0.1µF bypass capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction eliminates leadframe, reducing size by >50% vs. standard SOT-23 and minimizing parasitic inductance. |
| Ioff partial-power-down | Automatically disables I/Os when VCC = 0V, blocking back-current flow and enabling safe hot-swap in multi-supply systems. |
| 5.5V-tolerant inputs | Accepts 0V–5.5V input signals regardless of VCC level - eliminates need for external level translators in mixed-voltage designs. |
| Balanced CMOS outputs | Equal sourcing/sinking strength (±24mA @ 3.3V) ensures symmetric rise/fall times and reduces signal distortion on controlled-impedance lines. |
| Wide temperature range | Specified from –40°C to +125°C (DBV package), supporting industrial and automotive under-hood applications. |

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 |
|---|---|---|---|
| SN74LVC1G74DBVR | Dual D-flip-flop in same SOT-23-5 package; includes asynchronous set/reset (SR) inputs; higher ICC (20µA max). | Required when initialization control or dual-channel operation is needed; unsuitable if only single FF with minimal footprint is required. | Choose SN74LVC1G74DBVR only if SR functionality or dual FF density justifies 2× gate count and added complexity. |
| 74AUP1G80GW,125 | Lower ICC (0.9µA typ), smaller SC-70-5 package (2.0mm × 1.25mm), but reduced drive (±4mA @ 3.3V) and narrower VCC (0.8V–3.6V). | Better for ultra-low-power wearables; incompatible with 5V-tolerant or high-drive requirements. | Select 74AUP1G80GW,125 only for battery-critical designs operating ≤3.6V where drive strength and voltage tolerance are secondary. |
Compared with SN74LVC1G74DBVR and 74AUP1G80GW,125, the SN74LVC1G80DBVRE4 uniquely balances 5.5V input tolerance, ±24mA drive, and SOT-23-5 compactness - making it optimal for industrial and telecom systems requiring robust mixed-voltage interfacing without sacrificing speed or power efficiency.

FAQ
What is the maximum clock frequency supported by the SN74LVC1G80DBVRE4?
The SN74LVC1G80DBVRE4 supports up to 160MHz clock frequency at VCC = 1.8V, 2.5V, 3.3V, or 5V across –40°C to +85°C ambient, as confirmed by timing characterization in Section 5.6 of the official datasheet. At 3.3V and 15pF load, typical fmax exceeds 200MHz due to 4.2ns tpd, though guaranteed spec remains 160MHz for full temperature/voltage coverage. The SN74LVC1G80DBVRE4 maintains this rating without derating up to +125°C for DBV-packaged units.
Does the SN74LVC1G80DBVRE4 support 5V-tolerant inputs when powered from 1.8V?
Yes, the SN74LVC1G80DBVRE4 explicitly supports input voltages up to 5.5V regardless of VCC level - including when VCC = 1.8V - as stated in Section 5.3 (Recommended Operating Conditions) and Section 5.1 (Absolute Maximum Ratings). This 5V-tolerance eliminates external level-shifting circuitry when interfacing with legacy 5V peripherals or mixed-voltage sensor buses, and is a defined feature of the LVC family architecture.
How does the Ioff feature function in the SN74LVC1G80DBVRE4?
The Ioff circuitry in the SN74LVC1G80DBVRE4 automatically places all inputs and outputs into high-impedance state when VCC = 0V, limiting leakage to ±10µA maximum per pin (Section 5.5). This prevents back-driving current from live signal lines into a powered-down section of the system - critical for hot-plug capability, power gating, and safe multi-rail sequencing. The SN74LVC1G80DBVRE4 achieves this without external enable controls or bias resistors.
Can the SN74LVC1G80DBVRE4 be used as a divide-by-2 frequency divider?
Yes, the SN74LVC1G80DBVRE4 can be configured as a reliable divide-by-2 counter by connecting Q to D (with optional 10kΩ pull-up/bias resistor for initialization), as documented in Section 8.1 and Figure 8-1 of the datasheet. On each positive clock edge, the output toggles - producing a 50% duty-cycle square wave at half the input frequency. The SN74LVC1G80DBVRE4 exhibits no minimum pulse width limitation on CLK, supporting clean division down to DC and up to 160MHz.
What is the thermal resistance (RθJA) of the SN74LVC1G80DBVRE4 in its SOT-23-5 package?
The SN74LVC1G80DBVRE4 in DBV (SOT-23-5) package has a junction-to-ambient thermal resistance (RθJA) of 357.1°C/W, as specified in Section 5.4 of the datasheet. This value assumes standard JEDEC 2-layer board conditions (1s1p). For high-power-density layouts, designers should verify junction temperature using TJ = TA + (PDISS × RθJA), noting that typical ICC remains below 10µA - resulting in negligible self-heating under normal operation.
