                                                MC74LVX157MEL Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.209, 5.30mm Width).As a result, it is packaged in the way of Tape & Reel (TR).Digital switch ic uses a Surface Mount mounting method.In the multiplexers, the analog IC is indicated by Multiplexer.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.With a supply voltage of 2V~3.6V, designers have greater flexibility of digital controlled switch.The multiplexers from 74LVX series can be used for a wide range of applications.Its basic configuration includes terminations in the 16 range.The part number for 74LVX157 can be used to find its logic switch related parts as well.For multiplexer's system, a voltage of 2.7V is supplied.A component pin count of 16 is found on this turn signal switch.GULL WING represents the end of conductors.As a type of supply, Single is employed.A configuration of 16 pins is used.The mount is in Surface Mount.I would like to refer to the logic switch as a member of the LV/LV-A/LVX/H family.Keeping the minimum supply voltage (Vsup) at 2V prevents some unnecessary failures.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 3.6V.For mux switch's normal operation, power supply 3.3V is provided.The turn signal switch contains 1 outputs designed to operate.In accordance with TAPE AND REEL, switches can be packaged.On the multiplexers, 2 input lines are provided for accepting voltage levels.
