    Products Detail

    ST491ACDR Overview


    This LED driver IC features an enhanced 14-SOIC (0.154, 3.90mm Width) package for driving common LEDs.The receiver is packaged in a Tape & Reel (TR) package.As a Transceiver can transceiver, this part has enabled many applications to be served.This wide receiver can be placed on any Surface Mount-type PCB or development board.This differential driver uses 4.5V~5.5V for power supply.There can be up to 1/1 eligible receivers/drivers on the field at the same time with this electronic part.IC receiver has been designed primarily for applications operating at -40°C~85°C.With a supply voltage range of 5V, this line driver ic operates efficiently.It is packaged with 14 pinouts that are market standard for this particular transceiver.The base part number ST491 identifies the product type, temperature, package, etc., so you can search for more variants by using it.A 14-pin driver IC with enhanced power dissipation control is featured here.Through optical transceiver downsizing and high-density Surface Mount mounting technologies, its package size is reduced dramatically.Using this ic receiver, you were able to achieve a resolution of 1 bits.It is typical for this receiver to have a resolution of 1 bits when it is specified.An input voltage supply of 5V is required to operate the transceiver module.The driver IC in this product is designed so that it can be powered by 5V.1 transmitters are used in telecommunications to transmit or send data using radio waves.
