                                                PI4MSD5V9544ALEX Overview
Due to the lack of space on the board, digital switch is provided in the 20-TSSOP (0.173, 4.40mm Width).As a result, it is packaged in the way of Tape & Reel (TR).In terms of mounting, digital switch ic uses the method of Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 1.65V~5.5V, designers have superior flexibility.
