74F257ASC Overview
Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.In this case, it is packaged as Tube.digital switch ic uses the method of Surface Mount for mounting.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.In the case of 0°C~70°C, turn signal switch will not be affected by external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.These multiplexers are members of the 74F series, which provide extensive application potential.The base part number is 74F257, which is also useful when looking up signal switch's related components.In this case, Single is employed as the supply type.Currently, it is configured with 16 pins.The mounting point is Surface Mount.Signal multiplexer provides 4 bits.Not being affected by the external factors, consumes 15mA current of multiplexer ic.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.This multiplexer has 8 inputs.On the multiplexers, 2 input lines are provided for accepting voltage levels.There are 3 output lines designed to serve as the source of the signal.
