74HC257PW,118 Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-TSSOP (0.173, 4.40mm Width).It is packaged in the way of Tape & Reel (TR).Mounting is performed using Surface Mount.A digital IC Multiplexer is used as the analog component of the multiplexers.The operating temperature of -40°C~125°C will not be susceptible to external factors.When digital controlled switch operates at 2V~6V, designers have superior flexibility.In addition to being a member of the 74HC series, these multiplexers have a wide range of applications.There is a design for terminating 16 as part of its basic configuration.In addition, it also has a base part number of 74HC257, which can be used to find related parts.The multiplexer's system is supplied with a voltage of 5V.Currently, this turn signal switch has a total of 16 component pins.As a result, GULL WING represents the end of the conductors.As a type of supply, Single is employed.There are 16 pins on it.This unit is mounted in the way of Surface Mount.In the HC/UH family, the logic switch is included.Keep Vsup at 2V to avoid unnecessary failures.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.As a result, the turn signal switch consists of 4 outputs.Supply voltages of 5V can provide reliable performance of the multiplexers.As a voltage level input, the multiplexers have 8 lines.
