74AC257PC Overview


In order to conserve board space, digital switch is included in the 16-DIP (0.300, 7.62mm).It is packaged in the way of Tube.In terms of mounting, digital switch ic uses the Through Hole method .As the analog part, the circuit uses an analog IC Multiplexer.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility using digital controlled switch when it works with 2V~6V voltage.Multiplexers from the 74AC series can be used in a wide range of applications.There is a design for terminating 16 as part of its basic configuration.Signal switch has 16 component pins.The logic switch is a member of the AC family.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.Avoid unnecessary failures by keeping Vsup at 6V.The turn signal switch contains 1 outputs designed to operate.This multiplexer provides 2 inputs.
