Texas Instruments SN74LVC1G14 Single Schmitt-Trigger Inverter IC, SOT-23, 5-Pin

The Texas Instruments SN74LVC1G14DBVT is a single Schmitt-trigger inverter integrated circuit, engineered for reliable operation across a broad voltage range of 1.65V to 5.5V. This compact device performs the essential Boolean function Y = A, providing a dependable inverting logic gate for digital systems. Its defining feature is the built-in Schmitt-trigger input, which provides different positive-going (VT+) and negative-going (VT-) input threshold levels. This action significantly enhances noise immunity by providing hysteresis, ensuring clean output transitions even with slow or noisy input signals.

A critical advantage for modern power-sensitive designs is its support for partial-power-down applications via the Ioff circuitry. This feature disables the outputs when the device is powered down, preventing damaging current backflow and protecting the rest of the system. The IC boasts impressive ESD protection, exceeding JESD 22 standards including 2000V Human Body Model and 1000V Charged Device Model, offering robustness in handling and operation.

Key Performance Features

• Wide Voltage Range: Supports 5V VCC operation with inputs tolerant up to 5.5V.
• High Speed: Offers a maximum propagation delay (TPD) of just 4.6ns at 3.3V.
• Low Power: Consumes a maximum of 10µA (ICC), ideal for battery-powered devices.
• Strong Drive: Delivers ±24mA output drive at 3.3V.
• High Reliability: Latch-up performance exceeds 100mA per JESD 78, Class II.
