    Products Detail

    ST491ACN Overview


    This driver chip is excellent for driving common LEDs due to its enhanced 14-DIP (0.300, 7.62mm) package.The package of this receiver is Tube.It has proved to be a valuable component for a variety of applications since it is a Transceiver can transceiver.On any Through Hole-type PCB or development board, you can install this wide receiver.It takes 4.5V~5.5V from the power supply to run this differential driver.During operation, this electronic part may have up to 1/1 eligible receivers/drivers.IC receiver is designed for applications with a temperature of -40°C~85°C.Driver ICs in this category can operate efficiently with a supply voltage range of 5V.Wide receiver has 14 terminations built in for driving or receiving signals from data.As a standard package, this transceiver comes with a 14-pin layout that follows the market standard.Since the base part number ST491 uniquely identifies the product type, temperature, package, etc., you can use it to find more variations.14-pin driver IC with improved power dissipation control.This package size decreases dramatically due to optical transceiver downsizing and high-density Through Hole mounting technologies.It provided a 1-bit resolution capability with this ic receiver.As a general rule, this receiver has a resolution of 1 bits that is usually specified.A rf transceiver module named Line Driver or Receivers belongs to this subcategory.There is one driver IC that is designed to operate from a 5V power supply, and only one driver IC in total.
