Dual Schmitt inverter for automotive logic conditioning
The SN74LVC2G14IDCKRQ1 is a Texas Instruments dual inverter with Schmitt-trigger inputs, part of the Automotive AEC-Q100 74LVC series. It fits signal-conditioning roles where slow or noisy edges need clean digital outputs — think switch debounce, oscillator buffers, or sensor threshold detection in engine-control and body-electronics modules.
Supply range and drive strength
Operates from 1.65V up to 5.5V, covering the common automotive logic rails: 1.8V for modern MCU I/O, 3.3V for peripheral buses, and 5V for legacy sensor interfaces. The 32 mA symmetric output drive (both high and low) means it can sink or source enough current to drive an optocoupler LED or a small relay coil directly, saving a transistor per channel. Propagation delay is 4.3 ns typical at 5V with a 50 pF load — fast enough for CAN transceiver glitch filtering or clock buffering up to about 50 MHz without introducing skew.
Automotive qualification and lifecycle
AEC-Q100 qualified, meaning it has passed the full automotive stress suite (temperature cycling, HAST, high-temperature operating life). Texas Instruments continues to manufacture this part, and it is available for new designs. ROHS3 compliant, no exemptions to track.
Package and footprint
Supplied in SC-70-6 (SOT-363), a 6-lead surface-mount package with 0.65 mm pitch. The small footprint suits space-constrained ECU boards; the 0.65 mm pitch is hand-solderable with a fine tip but benefits from a stencil for reflow. The cut-tape option (CT) is useful for prototype runs, while tape-and-reel (TR) feeds pick-and-place for production.
