Product details
Overview
74LVC1G80GX,125 from Nexperia is a single positive-edge-triggered D-type flip-flop in X2SON5 (SOT1226-3) package, operating from 1.65 V to 5.5 V supply. It stores data on LOW-to-HIGH clock transition with 0.9 ns minimum setup time at 3.0 V, ±24 mA output drive capability, and IOFF-enabled partial power-down protection. It serves as a level-translating storage element in mixed-voltage digital control paths such as FPGA I/O bridging and sensor interface synchronization.
For engineers reviewing the 74LVC1G80GX,125 datasheet, 74LVC1G80GX,125 pinout, 74LVC1G80GX,125 application, or 74LVC1G80GX,125 equivalent, key selection criteria include edge-trigger timing margin at 1.65 V operation, IOFF leakage under 2 μA during power-down, Schmitt-trigger input tolerance for slow-rising control signals, and thermal-enhanced X2SON5 footprint compatibility with high-density PCB layouts.
Technical Context
This device implements a synchronous edge-triggered storage cell with non-inverting Q output and no reset/set control. Its Schmitt-trigger inputs accept slow-rising waveforms up to 20 ns/V slew rate at 1.65 V, enabling direct connection to mechanical switches or RC-debounced signals without external conditioning.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA while allowing live-bus operation in hot-swap or partial-power-down systems. All logic thresholds scale with VCC, supporting interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V domains without level-shifter ICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 5.5 V - supports direct interface between 1.8 V microcontrollers and 5 V peripherals |
| Propagation delay (tpd) | 0.9 ns (min) at VCC = 3.0 V - enables reliable sampling of ≥160 MHz clock domains |
| Output drive | ±24 mA at VCC = 3.0 V - drives standard CMOS loads or short PCB traces without buffering |
| IOFF leakage | ±2 μA max at VCC = 0 V - prevents damaging back-current during system power sequencing |
| Operating temperature | −40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments |
| Input hysteresis | Schmitt-trigger action - rejects noise on slow-rising enable or clock lines from sensors/switches |
| ESD rating | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events per JEDEC JS-001/JS-002 |
Pinout & Package
X2SON5 (SOT1226-3) package: plastic thermal-enhanced extremely thin small outline, no leads, 5 terminals, body size 0.8 × 0.8 × 0.32 mm, side-wettable flanks not present, pin 1 index located at lower-left corner below marking "VT".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D | Data input sampled on rising clock edge; accepts overvoltage up to 5.5 V independent of VCC |
| 2 | VCC | Primary supply rail; powers internal logic and output buffers; IOFF activates when VCC = 0 V |
| 3 | GND | Reference ground for all inputs/outputs; required for valid logic thresholds and ESD path |
| 4 | Q | Inverted data output - complements stored D value; drives loads up to ±24 mA |
| 5 | CP | Clock pulse input with Schmitt-trigger; triggers storage only on LOW-to-HIGH transition |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65 V to 5.5 V enables single BOM part across 1.8 V, 2.5 V, 3.3 V, and 5 V subsystems |
| IOFF partial power-down | Prevents backflow current during VCC ramp-down; critical for hot-plug and multi-rail sequencing |
| Schmitt-trigger inputs | Accepts slow-rising signals down to 10 ns/V at 5 V - eliminates need for external RC filtering |
| Overvoltage-tolerant inputs | Withstand 5.5 V input regardless of VCC - allows safe interfacing with higher-voltage logic |
| Thermal-enhanced X2SON5 | 0.32 mm height and 0.64 mm² footprint reduce thermal resistance for high-density routing |
Applications
| Industrial PLC I/O Expansion | FPGA Configuration Latching |
|---|---|
|
Use Scenario: Isolating and synchronizing discrete sensor inputs (e.g., limit switches, photoelectric sensors) into a 24 V PLC backplane via optocoupler interfaces. IC Role / Device Role / Timing Role: Positive-edge D flip-flop capturing debounced switch states synchronized to a 10 MHz system clock.

IC Role / Device Role / Timing Role: Edge-triggered register aligning asynchronous LIN frame edges to MCU clock domain. Use Value: −40 °C to +125 °C rating matches under-dash thermal requirements; HBM >2000 V withstands vehicle-level ESD pulses. |
Use Scenario: Controlling VCONN power enable timing relative to USB-C CC line detection in portable chargers and docks. IC Role / Device Role / Timing Role: Storage element holding negotiated power role state during PD negotiation handshake. Use Value: Overvoltage-tolerant D and CP pins interface safely with 5 V CC line sensing; X2SON5 footprint saves space near USB-C connector. |
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 |
|---|---|---|---|
| SN74LVC1G74DCKR | Dual D-flip-flop in SC-70 (SOT323); no IOFF; 1.65–5.5 V; 2.5 ns tpd min at 3.3 V | Higher propagation delay limits use in >100 MHz clock domains; dual-channel layout increases PCB area | Select when dual flip-flop functionality is needed and IOFF is not required for power sequencing |
| 74LVC1G74GW,125 | Single D-flip-flop in TSSOP5 (SOT353); includes IOFF; 1.65–5.5 V; 1.0 ns tpd min at 3.0 V; larger 1.25 mm body width | TSSOP5 footprint occupies ~3× more board area than X2SON5; same thermal performance but less dense routing | Select when hand-soldering or legacy TSSOP reflow profiles are used, and space constraints are less critical |
Compared with SN74LVC1G74DCKR and 74LVC1G74GW,125, the 74LVC1G80GX,125 delivers superior timing density (0.9 ns tpd), smallest footprint (0.64 mm²), and identical IOFF protection-making it optimal for space-constrained, high-speed, multi-rail embedded systems requiring robust power sequencing.

FAQ
Does 74LVC1G80GX,125 support true bidirectional level translation?
No. It functions as a unidirectional D-type flip-flop with overvoltage-tolerant inputs, enabling 5 V signals to drive its D or CP pins while powered from 1.8 V or 3.3 V. True bidirectional translation requires dedicated translators like NXSA5001 or TXB0108, as this device lacks automatic direction sensing or dual-supply I/O architecture.
Can the 74LVC1G80GX,125 be used without external pull-up or pull-down resistors on D or CP inputs?
Yes. Its Schmitt-trigger inputs provide built-in hysteresis and defined logic thresholds across the full 1.65–5.5 V VCC range, eliminating the need for external biasing in most cases. However, floating inputs remain undefined and must be avoided; unused inputs should be tied to VCC or GND.
What is the maximum clock frequency supported by 74LVC1G80GX,125 at 1.65 V supply?
At VCC = 1.65 V, the maximum guaranteed clock frequency is 160 MHz, derived from the 9.9 ns maximum propagation delay (tpd) and 2.3 ns minimum setup time (tsu) specified over −40 °C to +85 °C. Derating applies above +85 °C ambient per the 3.0 mW/K thermal derating curve for SOT1226-3.
How does the IOFF feature behave when VCC is ramping from 0 V to nominal voltage?
IOFF activates when VCC falls below approximately 0.8 V and remains active until VCC exceeds ~1.2 V, ensuring outputs stay high-impedance during power-up and power-down transitions. This prevents contention on shared buses and avoids back-current flow into partially powered subsystems during sequencing.
