SN74LS321N Product Details

SN74LS321N Overview


The PDIP package includes this clock generator. In the reflowing process, this clock generator ic is able to maintain a maximum temperature of NOT SPECIFIED. In it, there are 16 terminations to be found. This time clock generator should be voltaged at 5V. Clock generators can take up to 5.25V of power as a maximum supply voltageThe digital clock generator incorporates CLOCK GENERATOR, OTHER uPs, uCs, and peripheral ICs. This frequency synthesizer requires a supply voltage above 4.75V to be safe. Whenever the operating temperature for the PLL exceeds 70°C, it may become ha70°Cardous. Clock PLL synthesi20MHzes a high-quality 20MHz clock output frequency. Microprocessors are specifically designed to use this clock-generating IC, which has a 16-bit output. PF synthesizers is equipped with 16 pins. A supply current exceeding 75mA may cause an element to melt.
