LE57D111BTC Overview
To save board space, the 44-TQFP Exposed Pad package is used.Packing is done according to the Tray method.A Surface Mount mounting type is used.The telecom IC is composed of 2 circuits.A higher supply voltage for 4.75V~5.25V will improve efficiency.The operating temperature set at -40°C~85°C can offer reliable performance.Surface Mount is the way telecom switching is mounted.As a telecom IC, SLIC is used.A current of 9mA is used as the supply current.In order to provide designers with a great deal of flexibility, this telecom circuit operates on the supply voltage of 5V.A designer can make use of this telecom circuit by operating with the 9mA supply current.There are many similar functions of the telecommunication product that it can provide with the electronic components under the - series.A minimum temperature value -40°C is set to ensure normal operation.In order to maintain normal operation, 85°C must be set at its maximum value.During design, 1 functions are configured.Ideally, the voltage should be at least 4.75V.44 telecom products have pins designed specifically for their configuration.
LE57D111BTC Features
