ST491ACN Product Details

ST491ACN Overview


An excellent driver IC for common LEDs thanks to its enhanced 14-DIP (0.300, 7.62mm) package.There is a Tube package for this receiver.The Transceiver can transceiver technology has enabled this part to power many solutions for a variety of uses.On any Through Hole-type PCB or development board, this wide receiver can be placed.In terms of power supply, this differential driver utilizes 4.5V~5.5V.During operation, this electronic part may have up to 1/1 eligible receivers/drivers.In most applications, this ic receiver is used in environments where -40°C~85°C is the operating temperature.With a supply voltage range of 5V, this line driver ic operates efficiently.In this wide receiver, 14 terminations are integrated for driving and receiving signals from data.Transceiver comes with 14 standard pinouts that meet the market's requirements.ST491 is the base part number for this part, and it identifies the product type, temperature, packaging, etc., so you can search for more variants with it.It is a 14-pin driver IC with enhanced power dissipation controls.Through optical transceiver downsizing and high-density Through Hole mounting technologies, its package size is reduced dramatically.Using this ic receiver, you were able to achieve a resolution of 1 bits.There is usually a 1-bit resolution specified for this receiver when it is used.There is a subcategory called Line Driver or Receivers for this rf transceiver module.There is one driver IC that is designed to operate from a 5V power supply, and only one driver IC in total.
