74HCT157DB,112 Overview
In order to conserve board space, digital switch is included in the 16-SSOP (0.209, 5.30mm Width).In this case, it is packaged as Tube.The method digital switch ic adopts for mounting is Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.If the operating temperature is maintained at -40°C~125°C, turn signal switch will not be susceptible to external factors.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.As a member of 74HCT series, the multiplexers can be used for a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.There is a base part number of 74HCT157 which can also be used in order to locate the logic switch that are related to this item.For multiplexer's system, a voltage of 5V is supplied.A component pin count of 16 is found on this turn signal switch.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.This supply type employs Single.The board is configured with 16 pins.Multiplexer ics are mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the HCT family.Supply voltages of 5V can provide reliable performance of the multiplexers.The multiplexer provides 8 inputs.Voltage levels are accepted through 10 input lines of multiplexers.A signal source is provided by 4 output lines.
