SN74LS628DRE4 Product Details

SN74LS628DRE4 Overview


Tape and Reel-method packaging is used for clock ICs. The SOIC package contains this clock generator. This clock generator ic can sustain a maximum temperature of 260 during reflowing. It contains 14 terminations that can be found in frequency synthesizer. This electronic frequency generator requires a voltage of 5V. The clock-generating IC is a 14-bit device designed specifically for microprocessors. It is possible to connect to the frequency generators via 14 pins. Despite its low-temperature operation, this clock generator ic is capable of 0°C operations. Despite its attenuated performance, this frequency synthesizer can last at 70°C. There is a maximum supply voltage of 5V that clock generator can handle. When searching for parts of the LS family, similar frequency generators will be found. It is unacceptable to supply this clock PLL with a voltage higher than 5.25V. There is a maximum supply voltage of 4.75V for this RF synthesizer. Logic circuits based on LOGIC CIRCUIT logic use this electronic frequency generator. At a frequency of 25MHz, frequency generator is capable of achieving high efficiency. For the RF synthesizer to function properly, a supply current of 20mA must be provided. In terms of load capacitance, analog clock generator is capable of delivering 45pF.
