CD74HC297EE4 Product Details

CD74HC297EE4 Overview


As part of the PDIP package, this clock generator is embedded. There are 16 terminations found in this file. To operate this time clock generator, 4.5V voltage should be applied. In this clock generator, Clock is used as the input to the clock. An up to 55MHz frequency is provided by this clock-based RF synthesizer. It is a 16-bit clock PLL designed specifically for microprocessors. There are 16 pins on the frequency generators that are available for use. There are -55°C operations that can be performed on this clock generator, which has impressive low-temperature performance. At 125°C, this RF synthesizer remains functional despite reduced performance. By searching for parts that belong to the HC/UH family, you can find electronic parts that are similar. There is no way that a voltage higher than 6V can be supplied to this clock generator. Powered by 2V, this clock generator has the lowest supply voltage limit. LOGIC CIRCUIT logic circuits are primarily constructed using this time clock generator. Using a frequency of 55MHz allows frequency synthesizer to achieve high efficiencies. This clock generator ic is ideal for the TUBE package that comes with it.
