LE57D121BTCT Overview
A 44-TQFP Exposed Pad package saves space on a board.For telecommunications equipment packing, the Tape & Reel (TR) method is used.Telecommunications equipment is mounted with type Surface Mount.2 circuits are used in this telecom IC .Providing 4.75V~5.25V wtelecom IC's efficiencyh the correct supply voltage will improve efficiency.-40°C~85°C is the operating temperature that can be set for reliable performance.The mounting is in the way of Surface Mount.In order to provide designers with a great deal of flexibility, this telecom circuit operates on the supply voltage of 5V.To give designers much flexibility, it uses 9.3mA as the supply current.During normal operation, a minimum value of -40°C is set for the temperature.To ensure normal operation, 85°C is set at maximum.A voltage of at least 4.75V should be supplied.
