SN74LS191NSRG4 Overview


In the SOICpackage, it is supplied. In order to configure it, it uses 16terminations. The supply voltage of 5V enables it operate in a fully flexible way. The 1elements are connected by wires. In all, there are 16 pins on each component. In this case, it is packaged as Tape & Reel (TR). To connect the circuit's other components, there are 16pins. Surface Mountis the way in which it is mounted. It is included in the LSfamily. There is information in the device in the form of 4bits. It is possible for the result to be noin Pbfree code. It is important to note that in regards to this electronic device, TCO OUTPUTis an extremely significant feature. There is a temperature grade of COMMERCIALon this device. The packing of the product is carried out by [0]. From the voltage source, there is a voltage of 5V volts. In order to operate, it requires a voltage of [0]. Long-term operation at 70°Cwith acceptable electrical stability is possible. Temperature ranges are specified, with 0°Cset as a lower limit. A frequency of 25MHzis used for operation.
