Product details
Overview
SN74LVC1G80DBVR from Texas Instruments is a single positive-edge-triggered D-type flip-flop designed for 1.65V to 5.5V operation, delivering 4.2ns maximum propagation delay at 3.3V, ±24mA output drive, and Ioff-enabled partial-power-down protection. It serves as a synchronous data latch in clock-domain interfacing, frequency division, and signal synchronization circuits within compact digital systems.
For engineers reviewing the SN74LVC1G80DBVR datasheet, SN74LVC1G80DBVR pinout, SN74LVC1G80DBVR application, or SN74LVC1G80DBVR equivalent, key selection criteria include its SOT-23 (DBV) package footprint, guaranteed 160MHz max clock frequency at 1.8V–5.5V, sub-10ns timing across voltage/temperature ranges, and robust over-voltage tolerant inputs up to 5.5V independent of VCC.
Technical Context
The SN74LVC1G80DBVR implements a CMOS-based positive-edge-triggered D flip-flop with transmission-gate logic architecture. Its clock input triggers on a voltage threshold-not edge slew rate-enabling reliable sampling even with slow-rising clocks. The device features standard CMOS inputs with 3.5pF typical input capacitance and balanced push-pull outputs capable of sourcing/sinking ±24mA at 3.3V.
It supports true partial-power-down via Ioff circuitry, disabling all I/Os when VCC = 0V to prevent back-drive current and latch-up. Input voltage tolerance extends to 5.5V regardless of VCC level (1.65V–5.5V), enabling mixed-voltage interface bridging without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains. |

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 |
|---|---|---|---|
| 74LVC1G74DCUR | Dual D-type flip-flop in SC70-8; no Ioff; 3.5ns tpd at 3.3V; requires separate VCC per section. | Higher gate count but larger footprint; lacks partial-power-down capability for hot-swap designs. | Select when dual-latch functionality is needed and Ioff is not required; verify layout compatibility with SC70-8. |
| SN74AUP1G79DBVR | Ultra-low-power variant: 0.9V–3.6V range; 11ns tpd at 1.2V; 0.5µA ICC; no over-voltage tolerance. | Optimized for sub-1V battery-powered IoT sensors; incompatible with 5V interfaces or mixed-voltage systems. | Select only for ultra-low-power, single-rail 1.2V–3.3V applications where 5V tolerance and speed are secondary. |
Compared with 74LVC1G74DCUR and SN74AUP1G79DBVR, SN74LVC1G80DBVR uniquely combines 5.5V input tolerance, Ioff protection, and 4.2ns speed in a 5-pin SOT-23-making it the only choice for compact, mixed-voltage, hot-pluggable digital control nodes.

FAQ
What is the maximum clock frequency supported by the SN74LVC1G80DBVR?
The SN74LVC1G80DBVR supports up to 160MHz clock frequency across its full operating range (1.8V–5.5V) at temperatures from –40°C to +85°C. At +125°C, this remains valid for DBV and DCK packages per TI's SCES221T datasheet Section 5.6 and 5.7. This makes SN74LVC1G80DBVR suitable for high-speed control loops and clock-domain bridging in industrial automation systems.
Does the SN74LVC1G80DBVR support operation at 1.8V supply voltage?
Yes, the SN74LVC1G80DBVR is fully specified for 1.65V to 5.5V operation, including stable 1.8V functionality. At 1.8V, it delivers 9.1ns maximum propagation delay (CL = 15pF), 2.5ns minimum clock pulse width, and meets all timing requirements down to –40°C. This enables direct use in modern low-voltage microcontroller peripherals and sensor interfaces.
Can the SN74LVC1G80DBVR inputs safely accept 5V signals when powered from 3.3V?
Yes - the SN74LVC1G80DBVR inputs are over-voltage tolerant up to 5.5V regardless of VCC level. When powered from 3.3V, D and CLK pins may be driven with 5V logic signals without damage or need for external resistors or clamps. This capability is explicitly confirmed in Section 5.3 (Recommended Operating Conditions) and Section 7.3.5 of the TI SCES221T datasheet.
What is the purpose of the Ioff feature in the SN74LVC1G80DBVR?
The Ioff feature in the SN74LVC1G80DBVR disables all inputs and outputs when VCC = 0V, limiting leakage current to ±10µA. This prevents back-drive current from live signal lines into a powered-down system, protecting both the SN74LVC1G80DBVR and connected devices during hot-swap, power sequencing, or partial shutdown. It is critical for modular systems and FRU (Field Replaceable Unit) designs.
Is the SN74LVC1G80DBVR pin-compatible with other 5-pin SOT-23 logic devices?
The SN74LVC1G80DBVR uses the standard 5-pin SOT-23 (DBV) footprint with pin 1 = D, pin 2 = CLK, pin 3 = GND, pin 4 = Q, pin 5 = VCC - matching TI's industry-standard pinout for single-gate logic. However, functional compatibility depends on logic type: it is not pin-compatible with inverters (e.g., SN74LVC1G04) or buffers due to differing internal functions and signal routing.
