Product details
Overview
SN74LVC1G00 from Texas Instruments is a single 2-input positive-NAND gate in SC70-5 (DCK) package, performing Y = A • B logic with 3.8ns max propagation delay at 3.3V, ±24mA output drive, and 5.5V-tolerant inputs-used for level translation, enable control, and signal inversion in portable audio and embedded timing circuits.
For engineers reviewing the SN74LVC1G00 datasheet, SN74LVC1G00 pinout, SN74LVC1G00 application, or SN74LVC1G00 equivalent, key selection considerations include Ioff-enabled live insertion support, 1.65V–5.5V supply range, ultra-small 2mm × 2.1mm footprint, and guaranteed 10μA max ICC across temperature.
Technical Context
This device implements standard CMOS NAND logic with balanced push-pull outputs capable of sourcing/sinking up to ±24mA at 3.3V. Its over-voltage tolerant inputs accept up to 5.5V independent of VCC, enabling down-translation from higher-voltage domains into 1.65V–3.3V logic systems.
The Ioff feature disables all outputs when VCC = 0V, preventing back-drive current and supporting partial power-down modes. Input transition rate requirements (5 ns/V at 5V) ensure reliable switching without oscillation, and latch-up immunity exceeds 100mA per JESD78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive-NAND (Y = A • B) |
| Supply Voltage Range | 1.65V to 5.5V - supports mixed-voltage system interfacing |
| Max Propagation Delay | 3.8ns at 3.3V, CL = 15pF - enables high-speed control signaling |
| Output Drive | ±24mA at 3.3V - drives moderate capacitive loads without external buffers |
| Input Voltage Tolerance | Up to 5.5V - allows direct connection to 5V buses while powered from 3.3V or lower |
| Quiescent Current | 10μA max ICC - suitable for battery-powered always-on monitoring functions |
| Ioff Support | Active at VCC = 0V - enables hot-plug and partial-power-down system architectures |
Pinout & Package
SN74LVC1G00DCKR uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm pitch, 5-terminal surface-mount configuration with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | First NAND input; accepts 0–5.5V; must be terminated to VCC or GND if unused |
| B | Input | Second NAND input; same voltage tolerance and termination requirement as A |
| GND | Ground | Reference return path for logic and output currents; connects to PCB ground plane |
| Y | Output | Active-low NAND result; push-pull structure sinks or sources up to ±24mA |
| VCC | Power | Supply pin; bypassed with 0.1μF capacitor near pin; supports 1.65–5.5V operation |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant inputs | Accepts 5.5V signals while operating from 1.65V–3.3V supplies - eliminates level-shifters in mixed-voltage I/O |
| Ioff partial power-down | Blocks current flow between inputs/outputs when VCC = 0V - enables safe live insertion and system sleep states |
| Ultra-small X2SON-compatible footprint | 0.64mm² DPW option available; DCK package occupies only 4.2mm² board area - ideal for space-constrained portable designs |
| Low dynamic power | 23pF typical Cpd at 3.3V - reduces switching current and EMI in high-frequency enable/control paths |
| Robust ESD protection | 2000V HBM, 1000V CDM - meets industrial handling requirements without additional protection circuitry |
Applications
| Audio Dock Control | SSD Power Sequencing |
|---|---|
Use Scenario: Managing USB/line-in detection and LED status indication in portable audio docks. IC Role / Device Role / Timing Role: NAND gate implements active-low enable logic for audio codec power and tamper-indicator LED drive.

IC Role / Device Role / Timing Role: Configured as an inverter or enable gate to coordinate 1.2V/1.8V/3.3V rail sequencing with precise timing margins. Use Value: 3.8ns max tpd ensures sub-4ns timing resolution; Ioff prevents back-drive during staggered rail ramp-up. |
| Embedded PC Fan Control | HDTV HDMI Hot-Plug Detection |
Use Scenario: Converting thermal sensor alerts into PWM-enable signals for low-noise fan drivers in compact embedded PCs. IC Role / Device Role / Timing Role: NAND gate forms part of a simple combinational logic block that gates fan enable based on temperature and system activity flags.

IC Role / Device Role / Timing Role: Acts as a Schmitt-trigger-like signal conditioner using feedback configuration, rejecting noise on long HPD traces. Use Value: CMOS input hysteresis (via external resistor) combined with 5.5V tolerance handles noisy 5V HPD lines while interfacing to 3.3V SoC inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G00GW,125 (Nexperia) | Same logic function, SC70-5 package, but rated only to 125°C (vs. SN74LVC1G00's 125°C max); slightly higher 4.5ns tpd at 3.3V | Valid for industrial temp-range designs but lacks TI's documented Ioff behavior at 0V VCC | Select when cost sensitivity outweighs need for guaranteed zero-VCC Ioff or extended reliability validation |
| NC7SZ00P5X (ON Semiconductor) | SC70-5, 1.65–5.5V supply, but max output drive is ±24mA only at 4.5V - degrades to ±16mA at 3.3V | Suitable for low-load applications but may require buffering in high-capacitance fan-control or LED-drive use cases | Prefer when footprint compatibility is critical and drive strength >±20mA at 3.3V is not required |
Compared with 74LVC1G00GW,125 and NC7SZ00P5X, the SN74LVC1G00 delivers superior guaranteed Ioff behavior at 0V VCC and consistent ±24mA drive across its full 1.65–5.5V supply range - making it optimal for robust hot-swap and mixed-rail embedded control.

FAQ
What is the maximum input voltage the SN74LVC1G00DCKR can tolerate?
The SN74LVC1G00DCKR accepts input voltages up to 5.5V regardless of VCC level - a key feature enabling down-translation from 5V buses into 1.65V–3.3V logic domains. This specification is validated per Absolute Maximum Ratings and applies to both A and B inputs. Exceeding 5.5V risks permanent damage, even briefly.
Does the SN74LVC1G00DCKR support partial power-down mode?
Yes, the SN74LVC1G00DCKR supports partial power-down via its Ioff feature: when VCC = 0V, all outputs enter high-impedance state with leakage limited to ±10μA, preventing back-drive current and enabling safe live insertion. This behavior is characterized across –40°C to 125°C and is distinct from standard CMOS high-Z states.
What is the typical propagation delay of the SN74LVC1G00DCKR at 3.3V?
The SN74LVC1G00DCKR has a maximum propagation delay (tpd) of 3.8ns at VCC = 3.3V, CL = 15pF, and TA = 25°C. Typical delay under those conditions is 0.8ns. Delay increases with load capacitance and temperature - e.g., 4.7ns max at CL = 30pF and 85°C - values confirmed in the Switching Characteristics tables.
Can unused inputs on the SN74LVC1G00DCKR be left floating?
No - unused inputs on the SN74LVC1G00DCKR must be tied to either VCC or GND to prevent undefined logic states, excessive current draw, and potential oscillation. TI explicitly recommends termination via direct connection or a 10kΩ pull-up/pull-down resistor. Floating CMOS inputs violate Recommended Operating Conditions and compromise reliability.
What package type does SN74LVC1G00DCKR use, and what are its dimensions?
The SN74LVC1G00DCKR uses the SC70-5 (DCK) package: nominal body size 2.0mm × 2.1mm, overall footprint ~4.2mm², with 0.65mm lead pitch. It is distinct from the smaller DPW (X2SON) variant and larger DBV (SOT-23) version - this specific DCKR suffix denotes the SC70-5 packaging with tape-and-reel delivery.
