Overview
The SN74LVC1G175DCKR, 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 the output (Q) to be forced into a low state regardless of the clock edge or data input when CLR is low. The flip-flop operates on the rising edge of the clock (CLK), transferring data from the input pin (D) to the output pin (Q) when CLR is high.
The SN74LVC1G175DCKR is available in several package types, including SOT-23, SC70, SON, and DSBGA, making it versatile for various applications. It also incorporates NanoFree™ package technology, which uses the die as the package, enhancing packaging efficiency.
