74FST3345QSR Overview
In order to save board space, digital switch is located in the 20-SSOP (0.154, 3.90mm Width).As a result, it is packaged in a way that is referred to as Tape & Reel (TR).Digital switch ic uses a Surface Mount mounting method.The multiplexers uses an analog IC Bus Switch as the analog part of the circuit.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 4V~5.5V, designers have greater flexibility of digital controlled switch.Multiplexers of the 74FST series can be used in a wide range of applications.The basic configuration of this system includes 20 terminations.For multiplexer's system, a voltage of 4.5V is supplied.This turn signal switch consists of 20 component pins.As a result, GULL WING represents the end of the conductors.The logic switch is a member of the CBT/FST/QS/5C/B family.Signal multiplexer provides 8 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 4V.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 5.5V.The system operates with a resistance of 2.
