DS2187S/T&R Overview

Space is saved on the board by using the 20-SOIC (0.295, 7.50mm Width) package.The way of Tape & Reel (TR) is employed for telecommunications equipment packing.Mounting type Surface Mount is used.The telecom IC is composed of 1 circuits.The voltage supplied to 4.75V~5.25V can improve efficiency.A 0°C~70°C-temperature setting offers reliable performance.Telecom switching's base part number, DS2187, can be used to find related parts.A 18mA supply current is required to operate telecom equipment .The telecom circuit operates with a supply voltage of 5V, giving designers a great deal of freedom.Normal operation is ensured by setting 0°C to a minimum value.It is necessary to set the temperature at the maximum value of 70°C for the telecom IC to function normally.Voltage supplied should be 4.75V at least.A lower voltage than 5.25V should be supplied.In order to maintain normal operation, the supply current should be maintained at 25mA.
