Core Features & Advantages
The SN74LVC1G08DCKR delivers a single 2-input AND gate in an ultra-compact SC-70 package, enabling precise logic gating with minimal board space and near-zero static power dissipation.
- Primary Function: Single-channel 2-input positive-AND gate performing the Boolean function Y = A · B, used for enable gating, condition detection, and signal qualification in digital logic.
- Advantages:
- Ultra-Small Footprint (SC-70/DCK, 2.0×1.25mm): Occupies under 3 mm² of PCB area — ideal for space-constrained designs where a single logic gate must be added without routing to a multi-gate IC.
- Over-Voltage Tolerant Inputs (5.5V): Input pins accept voltages up to 5.5V regardless of VCC, enabling direct interfacing between 5V logic outputs and 3.3V logic domains without additional level shifters.
- Ioff Partial-Power-Down Support: When VCC is grounded, the Ioff circuitry disables outputs and prevents damaging backflow current — essential for multi-voltage systems with independent power domains and hot-swap scenarios.
Typical Application Scenarios
- Industry: Industrial / Automotive / Consumer Electronics
- Equipment: MCU enable logic, power sequencing, safety interlock circuits, portable devices
- Use Cases:
- Generating a combined enable signal from two independent conditions (e.g., “system ready” AND “safety check passed”) to gate a motor driver IC.
- Power-on sequencing where both a voltage supervisor output and a soft-start signal must be HIGH before enabling a downstream DC-DC converter.
- Condition detection in battery-powered IoT devices, using the AND gate to wake the MCU only when both a sensor threshold and a timer trigger are simultaneously active.
