Product details
Overview
SN74LVC1G175DBVR from Texas Instruments is a single D-type flip-flop with asynchronous clear, designed for 1.65-V to 5.5-V operation, featuring 4.3 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for live insertion and partial-power-down modes. It serves as a compact edge-triggered storage element in clock-synchronized digital control paths, such as serial data latching in point-of-sale terminals and motor drive logic sequencers.
For engineers reviewing the SN74LVC1G175DBVR datasheet, SN74LVC1G175DBVR pinout, SN74LVC1G175DBVR application, or SN74LVC1G175DBVR equivalent, this page delivers verified functional behavior, validated SOT-23-6 package mapping, confirmed timing parameters across –40°C to 125°C, and real-world implementation guidance for shift register construction and low-voltage interface bridging.
Technical Context
The SN74LVC1G175DBVR implements positive-edge-triggered D-flip-flop logic with an active-low asynchronous clear (CLR), enabling immediate output reset independent of clock state. Its CMOS design supports voltage translation: inputs tolerate up to 5.5 V regardless of VCC, and outputs drive loads at VCC levels from 1.65 V to 5.5 V.
It incorporates Ioff circuitry that disables outputs during power-down, preventing back-drive current flow, and meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM). The device operates reliably from –40°C to 125°C with guaranteed fmax up to 175 MHz at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across mixed-supply systems (e.g., 1.8-V MCU interfacing with 3.3-V peripherals) |
| tpd (max) | 4.3 ns at VCC = 3.3 V - supports high-speed sampling in serial shift registers and timing-critical control loops |
| Output Drive | ±24 mA at VCC = 3.3 V - sufficient to directly drive multiple LVC inputs or small LED indicators without buffering |
| Ioff Current | ±10 µA max - ensures safe live insertion and prevents back-current damage when VCC = 0 |
| Input Voltage Tolerance | Up to 5.5 V - allows interfacing with legacy 5-V logic while powered from lower VCC (e.g., 1.8 V or 2.5 V) |
| Operating Temperature | –40°C to +125°C - qualified for industrial motor drives, factory automation, and telecom infrastructure environments |
Pinout & Package
SOT-23-6 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, RoHS-compliant NiPdAu/Sn lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CLK | Clock input | Positive-edge-sensitive trigger; initiates synchronous data capture from D to Q only when CLR = high |
| 2 - GND | Ground reference | Return path for all internal logic and output currents; must be low-impedance and decoupled near the pin |
| 3 - D | Data input | Asynchronous data source; value latched on next CLK↑ if CLR remains high |
| 4 - Q | Non-inverting output | Stores and presents the latched D value; drives downstream logic or status indicators |
| 5 - VCC | Power supply | Primary bias for core logic and output buffers; requires local 0.1-µF ceramic bypass capacitor |
| 6 - CLR | Asynchronous clear input | Active-low reset: forces Q = low immediately, overriding CLK and D states |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Die-as-package construction eliminates bond wires and mold compound, reducing parasitic capacitance and enabling ultra-small 2.90 mm × 1.60 mm footprint |
| Ioff partial-power-down support | Disables outputs when VCC = 0, eliminating risk of damaging back-current during hot-plug or system sleep transitions |
| 5.5-V tolerant inputs | Allows direct connection to 5-V buses while operating from 1.65–3.3-V supplies - eliminates level-shifters in mixed-voltage designs |
| Low ICC (10 µA max) | Minimizes quiescent power in always-on monitoring circuits, battery-backed registers, and low-duty-cycle sensor interfaces |
| High ESD robustness | 2000-V HBM rating ensures reliability during board assembly and field handling without special ESD precautions |

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-edge-triggered D flip-flop with set/reset; no asynchronous clear; higher propagation delay (5.5 ns @ 3.3 V) | Lacks dedicated CLR - requires external logic for immediate reset; better suited for toggle or dual-phase clocking | Choose when dual DFF functionality is needed in same footprint, and asynchronous reset is implemented elsewhere |
| 74AUP1G74DBVR | Lower VCC range (0.8–3.6 V); lower ICC (0.9 µA typ); slower max speed (130 MHz @ 3.3 V); no 5.5-V input tolerance | Optimized for ultra-low-power battery devices; incompatible with 5-V signal domains or wide-supply systems | Prefer for energy-constrained IoT nodes where supply is fixed ≤3.3 V and 5-V compatibility is unnecessary |
Compared with SN74LVC1G175DBVR, SN74LVC1G74DBVR offers dual functionality but sacrifices dedicated asynchronous reset and speed, while 74AUP1G74DBVR trades voltage flexibility and interface robustness for extreme low-power operation - making SN74LVC1G175DBVR optimal for industrial mixed-voltage control where reliability and signal integrity are critical.

FAQ
What is the maximum clock frequency supported by SN74LVC1G175DBVR?
The SN74LVC1G175DBVR supports up to 175 MHz at VCC = 5 V and –40°C to 125°C ambient temperature. At 3.3 V, maximum frequency is 150 MHz under the same conditions. These values are guaranteed per TI's SCES560G datasheet switching characteristics tables and assume CL = 15 pF load and proper PCB layout with minimized trace inductance.
Does SN74LVC1G175DBVR support operation at 1.8 V?
Yes, SN74LVC1G175DBVR is fully specified for 1.65 V to 5.5 V VCC operation. At 1.8 V ±0.15 V, it delivers guaranteed tpd ≤12.9 ns and fmax ≥100 MHz across –40°C to 125°C, making it suitable for low-power portable and battery-operated equipment where supply headroom is constrained.
Can SN74LVC1G175DBVR inputs safely accept 5-V signals when powered from 2.5 V?
Yes - SN74LVC1G175DBVR inputs are rated for voltages up to 5.5 V regardless of VCC level. When powered from 2.5 V, the device correctly interprets 5-V logic-high inputs without damage or level-shifting circuitry, enabling seamless interfacing between legacy 5-V subsystems and modern low-voltage controllers.
How does the Ioff feature function in SN74LVC1G175DBVR?
The Ioff feature in SN74LVC1G175DBVR disables output drivers when VCC = 0 V, limiting Ioff current to ±10 µA max. This prevents back-driving current from live system buses into the unpowered device - a critical safeguard during hot-swap operations, partial power-down states, or board maintenance in modular industrial systems using SN74LVC1G175DBVR.
Is SN74LVC1G175DBVR pin-compatible with other 6-pin logic devices in SOT-23?
SN74LVC1G175DBVR uses standard SOT-23-6 (DBV) pinout per JEDEC MO-178, matching mechanical and solder-pad layout with other TI 6-pin logic devices like SN74LVC1G00DBVR and SN74LVC1G14DBVR. However, electrical functionality (e.g., DFF vs inverter vs Schmitt trigger) and signal routing differ - PCB redesign is required for functional substitution.
