SN74HC257DR Overview
As a means of saving space, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).Cut Tape (CT) represents its packaging.Digital switch ic uses a Surface Mount mounting method.the multiplexers uses IC Multiplexer as the analog IC.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.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.As part of its basic configuration, 16 terminations are designed as a part of it.In addition, it also has a base part number of 74HC257, which can be used to find related parts.The multiplexer's system is powered by 5V volts.Signal switch has 16 component pins.It is the end of conductors that is represented by GULL WING.This supply type employs Single.This multiplexer ic is configured with 16 pins.The multiplexer ic is mounted in the direction of Surface Mount.In the HC/UH family, the logic switch is included.In this signal multiplexer, there are 2 bits that are provided.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 2V.Vsup (maximum supply voltage) should be kept as 6V to prevent unnecessary failures.This turn signal switch has 1 outputs designed for its operation.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.A multiplexer such as this has 8 inputs available.The signal switching is packaged by TR. This turn signal switch's circuit is based on a circuit with 4 channels.
SN74HC257DR Features
