SN74HC138DBR Overview


In order to conserve board space, digital switch is included in the 16-SSOP (0.209, 5.30mm Width).The package is in the form of Cut Tape (CT).In terms of mounting, digital switch ic uses the Surface Mount method .A digital IC Decoder/Demultiplexer is used as the analog component of the multiplexers.When the operating temperature is kept at -40°C~85°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.In addition to being a member of the 74HC series, these multiplexers have a wide range of applications.It is designed with 16 terminations as part of its basic configuration.Its logic switch base part number is 74HC138 which can also be used to find its logic switch related parts.The multiplexer's system works with 5V voltage.This turn signal switch contains 16 component pins.GULL WING is used as the point at which the conductors come to an end as part of this formula.Its supply type is Single, which is used as the source of power.With 16 pins, it is configured.It is mounted in the way of Surface Mount.The logic switch is a member of the family of HC/UH.As a result, signal multiplexer provides a total of 8 bits.Keeping Vsup at 2V will prevent some unwanted failures.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.Normally, 2/6V is powered by a battery.The turn signal switch has 8 outputs.The part belongs to the Decoder/Drivers category of signal switches.It consumes 8μA current of multiplexer ic without external influences.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.It is provided with 3 inputs.The signal switching is packaged by TR. A normal operation of the digitalswitch requires 1 circuits.
