Product details
Overview
SN74LVC1G06DBVR from Texas Instruments is a single-channel CMOS inverter buffer with open-drain output, designed for 1.65V–5.5V VCC operation. It delivers 32mA sink current at 4.5V, supports 5.5V-tolerant inputs, and features Ioff partial-power-down protection. It is used in level translation, LED driving, and wired-OR logic in portable media players and embedded PCs.
For engineers reviewing the SN74LVC1G06DBVR datasheet, SN74LVC1G06DBVR pinout, SN74LVC1G06DBVR application, or SN74LVC1G06DBVR equivalent, key selection criteria include open-drain drive strength (32mA), input overvoltage tolerance (up to 5.5V), Ioff back-drive protection, propagation delay ≤4.5ns at 3.3V/125°C, and SOT-23-5 (DBV) package compatibility with space-constrained PCB layouts.
Technical Context
The SN74LVC1G06DBVR implements a single inverting logic gate with an open-drain NMOS output stage that sinks current to GND but cannot source current. Its Ioff circuitry ensures high-impedance outputs when VCC = 0V, preventing back-current flow during partial power-down sequences.
Input pins accept voltages up to 5.5V regardless of VCC, enabling bidirectional level translation between 1.8V, 2.5V, 3.3V, and 5V domains. The device exhibits Schmitt-trigger action on all inputs, improving noise immunity for slow or noisy signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and battery-powered operation down to 1.65V. |
| Max Sink Current (IOL) | 32mA at VCC = 4.5V - sufficient to directly drive LEDs or interface with higher-current loads without external transistors. |
| tpd (max) | 4.5ns at 3.3V, 125°C - enables reliable operation in high-speed digital control paths up to ~100MHz. |
| Ioff | ±10µA max - guarantees safe isolation during power sequencing and prevents damage from back-driving in multi-rail systems. |
| Input Voltage Tolerance | Up to 5.5V - allows direct connection to 5V logic or analog signals even when VCC is 1.8V or 2.5V. |
| ESD Rating (HBM) | 2000V - meets industrial-grade ESD robustness requirements per JESD22-A114A. |

Pinout & Package
SOT-23-5 (DBV) package: 2.90mm × 2.80mm footprint, 1.60mm body height, lead-free NiPdAu plating, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pin - must be left floating or tied to GND/VCC; no electrical function. |
| 2 (A) | Input | Inverting logic input - accepts 0V–5.5V signals independent of VCC; Schmitt-trigger enabled. |
| 3 (GND) | Ground reference | Primary return path for output sink current and internal logic; requires low-impedance PCB connection. |
| 4 (Y) | Open-drain output | Active-low output - sinks current when A = HIGH; requires external pull-up for logic HIGH state. |
| 5 (VCC) | Power supply | Supplies core logic and output driver - bypass with 0.1µF capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Dies-as-package construction eliminates bond wires and mold compound - reduces parasitic inductance and improves thermal resistance (RθJA = 357.1°C/W). |
| Ioff partial-power-down | Disables outputs and limits leakage to ±10µA when VCC = 0V - essential for hot-swap and multi-rail power sequencing. |
| 5.5V-tolerant inputs | Accepts input voltages beyond VCC (up to 5.5V) - enables seamless voltage translation without external level shifters. |
| High sink drive (32mA) | Supports direct LED driving or wired-OR bus termination - eliminates need for discrete MOSFET buffers in many applications. |
| Schmitt-trigger inputs | Hysteresis improves noise margin on slow or noisy control lines - prevents false triggering in industrial or automotive environments. |
Applications
| LED Driver Circuit | Level Translation Interface |
|---|---|
|
Use Scenario: Driving a status LED from a 1.8V microcontroller GPIO while powered from a 3.3V rail. IC Role / Device Role / Timing Role: Inverting open-drain buffer - converts active-high MCU signal to active-low LED enable with current limiting via external resistor. Use Value: Eliminates need for discrete transistor; 32mA sink capability supports bright indicator LEDs without derating at 125°C. |
Use Scenario: Interfacing a 5V sensor output to a 3.3V FPGA input requiring active-low interrupt signaling. IC Role / Device Role / Timing Role: Voltage-tolerant inverter - translates 5V logic HIGH to 0V output, pulled up to 3.3V on FPGA side. Use Value: Bidirectional translation without direction control pins; Schmitt input rejects sensor noise in industrial settings. |
| Wired-OR Bus Termination | Power Sequencing Monitor |
|
Use Scenario: Combining multiple reset signals onto a shared system reset line using active-low logic. IC Role / Device Role / Timing Role: Open-drain inverter - each device pulls bus LOW when its local condition asserts; external pull-up defines idle HIGH. Use Value: Enables fault-tolerant OR-ing of reset sources; 32mA sink ensures robust LOW assertion under capacitive bus loading. |
Use Scenario: Monitoring VCC rails during startup/shutdown in an embedded PC to generate sequenced enable signals. IC Role / Device Role / Timing Role: Power-aware inverter - Ioff blocks back-current when monitoring rail is unpowered, protecting upstream regulators. Use Value: Prevents latch-up or damage during asymmetric power sequencing; ±10µA Ioff ensures minimal leakage impact on rail stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G06DCKR | SC70-5 package (2.00mm × 2.10mm); RθJA = 371.0°C/W; identical electrical specs. | Smaller footprint but higher thermal resistance - less suitable for sustained 32mA operation in compact enclosures. | Choose for ultra-dense layouts where 0.9mm shorter length justifies thermal trade-off. |
| 74LVC1G06GW,125 | NXP SC-70-5; 32mA sink at 4.5V; Ioff = ±10µA; VI max = 5.5V; same logic function. | Qualified to AEC-Q100 Grade 2 (–40°C to +105°C); not rated to +125°C - unsuitable for under-hood automotive use. | Choose for cost-sensitive consumer electronics where full industrial temperature range is unnecessary. |

FAQ
What is the maximum sink current capability of the SN74LVC1G06DBVR?
The SN74LVC1G06DBVR provides a maximum sink current (IOL) of 32mA when VCC = 4.5V and ambient temperature is ≤125°C. This rating is confirmed in the Electrical Characteristics table under Recommended Operating Conditions. At lower VCC levels (e.g., 3.0V), the guaranteed sink current is 24mA. Exceeding these values risks thermal overload or parametric shift.
Does the SN74LVC1G06DBVR support level translation between different supply voltages?
Yes, the SN74LVC1G06DBVR supports bidirectional level translation due to its 5.5V-tolerant inputs and open-drain output. Inputs accept voltages up to 5.5V regardless of VCC, allowing a 5V signal to drive the A pin while VCC is 1.8V or 3.3V. The Y output is referenced to the external pull-up voltage, enabling translation from low-VCC to higher logic levels.
Can the SN74LVC1G06DBVR be used in partial-power-down systems?
Yes, the SN74LVC1G06DBVR includes Ioff circuitry that disables outputs and limits leakage to ±10µA when VCC = 0V. This feature prevents back-current flow into powered-down sections of a system, protecting both the SN74LVC1G06DBVR and upstream components during hot-swap or multi-rail sequencing - verified in Section 6.3.4 and Table 5.5.
What is the propagation delay of the SN74LVC1G06DBVR at 3.3V and 125°C?
The maximum propagation delay (tpd) of the SN74LVC1G06DBVR is 4.5ns at VCC = 3.3V and operating temperature of 125°C, as specified in Section 5.7 (Switching Characteristics: –40°C to +125°C). This value applies to the A-to-Y path under load conditions defined in Figure 6-1 (CL = 50pF, RL = 500Ω).
Is a pull-up resistor required for the SN74LVC1G06DBVR output?
Yes, the SN74LVC1G06DBVR has an open-drain output (Y pin) and cannot source current. A pull-up resistor to a valid logic HIGH voltage (e.g., 3.3V or 5V) is mandatory to establish a defined HIGH state when the output is not actively sinking. The resistor value must balance rise time requirements against power consumption and drive capability - typical values range from 1kΩ to 10kΩ.
