Product details
Overview
74V1G80CTR from STMicroelectronics is a single positive-edge-triggered D-type flip-flop with inverted output (Q̅), fabricated in sub-micron C2MOS technology. It operates from 2V to 5.5V, delivers 180MHz max clock frequency at 5V, features symmetrical 8mA output drive, and provides power-down input protection accepting 0–7V inputs regardless of VCC. It is used in level-shifting clocked data latching for portable 3.3V/5V mixed-voltage systems.
For engineers reviewing the 74V1G80CTR datasheet, 74V1G80CTR pinout, 74V1G80CTR application, or 74V1G80CTR equivalent, key selection criteria include edge-triggered DFF timing integrity, rail-to-rail input tolerance, low ICC (1µA max), ESD-hardened I/O, and SOT323-5L footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a synchronous edge-triggered storage element where Q̅ updates only on the rising edge of CK, with setup (3.0ns min at 5V) and hold (1.0ns) times tightly specified. Its logic function is strictly defined by the D→Q̅ transfer on CK↑, with no internal reset/set or asynchronous controls.
Designed for voltage translation, it supports 5V-to-3V and 3V-to-5V interfacing via overvoltage-tolerant inputs (−0.5V to +7.0V) and rail-swing outputs (0 to VCC), while maintaining noise immunity (VNIH/VNIL = 28% VCC min) and latch-up robustness across −55°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0V to 5.5V - Enables direct use in both 3.3V and 5V systems without level shifters |
| fMAX | 180MHz (typ) at VCC = 5V - Supports high-speed serial data capture and clock domain crossing |
| tPLH / tPHL | 3.5ns / 3.5ns (typ, 5V, CL=15pF) - Near-identical rise/fall propagation ensures precise timing alignment |
| IOH / IOL | −8mA / +8mA (min, VCC = 4.5V) - Drives standard CMOS loads with controlled edge rates |
| ICC (Quiescent) | 1µA (max, TA = 25°C) - Minimizes standby power in battery-operated devices |
| Input Voltage Range | −0.5V to +7.0V - Allows safe interfacing across supply domains without external clamping |
| ESD Protection | HBM > 2kV - Integrated protection eliminates need for external TVS on I/O lines |
Pinout & Package
SOT323-5L package: 1.35mm × 1.35mm × 0.95mm body, 0.65mm pitch, gull-wing leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D | Data input sampled on CK rising edge; accepts −0.5V to +7.0V independent of VCC |
| 2 | CK | Positive-edge clock trigger; VIH = 0.7VCC min ensures clean transition detection |
| 3 | GND | Reference ground for all I/O and internal logic; must be low-impedance |
| 4 | Q̅ | Inverted output; rail-to-rail swing (0 to VCC) with ±8mA drive capability |
| 5 | VCC | Positive supply; powers internal logic and output stage; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Supports 0–7V input signals regardless of VCC, enabling robust 5V↔3V interface without external components |
| Symmetrical output drive | IOH = IOL = 8mA (min) ensures matched rise/fall times and reduces signal distortion in transmission lines |
| Low dynamic power | CPD = 8pF enables predictable ICC(opr) = CPD × VCC × fIN + ICC, simplifying power budgeting in high-frequency operation |
| Wide temperature range | Specified from −55°C to +125°C - qualified for industrial and extended-temperature embedded control applications |
| Power-down input protection | Inputs remain high-impedance and non-latching when VCC = 0V, preventing back-powering of upstream drivers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G80DBVR | Lower VCC range (1.65–5.5V); 100MHz fMAX at 3.3V; no 7V input tolerance | Optimized for ultra-low-voltage logic; lacks overvoltage-safe interfacing | Prefer when system uses only 1.8V/3.3V rails and requires lower ICC |
| NC7SZ74P5X | Single DFF with non-inverted Q output; 5.5V max VCC; 240MHz fMAX at 5V | Requires external inverter for Q̅ functionality; higher speed but no input overvoltage rating | Choose when inverted output is not required and maximum clock rate is critical |
Compared with SN74LVC1G80DBVR and NC7SZ74P5X, the 74V1G80CTR uniquely combines 7V-tolerant inputs, true Q̅ output, and industrial temperature support-making it optimal for mixed-voltage legacy interface and ruggedized embedded designs where reliability trumps raw speed.

FAQ
Is the 74V1G80CTR pin-compatible with other SOT323-5L D-type flip-flops?
No-pinout differs from generic SOT323-5L logic devices. The 74V1G80CTR uses Pin 1=D, Pin 2=CK, Pin 3=GND, Pin 4=Q̅, Pin 5=VCC. Always verify against the official STMicroelectronics pin diagram before PCB layout.
Can the 74V1G80CTR operate reliably at 1.8V supply?
No-it is not characterized below 2.0V. The recommended VCC range is 2.0V to 5.5V. At 1.8V, VIH/VIL thresholds and output drive fall outside specification, risking metastability and functional failure.
Does the 74V1G80CTR include an asynchronous reset or set function?
No-the device has no asynchronous control inputs. It is a basic positive-edge-triggered D-type flip-flop with inverted output only. Reset/set functionality must be implemented externally using combinational logic or a different part number.
What is the maximum capacitive load the 74V1G80CTR can drive while maintaining 180MHz operation?
At VCC = 5.0V, the device is specified for CL ≤ 15pF to achieve 180MHz fMAX. Driving >15pF increases propagation delay and reduces maximum usable frequency; for 50pF loads, fMAX drops to 150MHz per AC characterization data.
