LE57D111BTCT [Microchip]

LE57D111BTCT Overview

Saving board space is achieved with the 44-TQFP Exposed Pad package.In order to pack telecommunications equipment, Tape & Reel (TR) is used.The mounting type of this telecom circuit is Surface Mount.There are 2 circuits in this telecom IC .4.75V~5.25V can be supplied wtelecom IC's efficiencyh a voltage that enhances efficiency.-40°C~85°C is the operating temperature that can be set for reliable performance.A Surface Mount-axis mount is used.A 9mA 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.To give designers much flexibility, it uses 9mA as the supply current.Ensure normal operation by setting the temperature to -40°C minimum.It is necessary to set the temperature at the maximum value of 85°C for the telecom IC to function normally.There should at least be 4.75V voltage supplied.
