Overview
The SN74LVC1G175DBVR, produced by Texas Instruments, is a single D-type flip-flop integrated circuit designed for a wide range of voltage operations from 1.65 V to 5.5 V. This device features an asynchronous clear (CLR) input, which allows for the forced reset of the output (Q) to a low state regardless of the clock edge or data on the input pin (D). The SN74LVC1G175DBVR is packaged in a SOT-23 (6) package, utilizing NanoFree™ package technology, which uses the die as the package itself. This technology enhances the device's performance and reduces its physical footprint.
