TRIPLE 4-INPUT MULTIPLEXER WITH ENABLE SY100S371 DESCRIPTION FEATURES ■ Max. propagation delay of 1000ps ■ IEE min. of –68mA ■ Industry standard 100K ECL levels ■ Extended supply voltage option: VEE = –4.2V to –5.5V ■ Voltage and temperature compensation for improved noise immunity ■ Internal 75KΩ input pull-down resistors ■ 40% faster than Fairchild ■ 40% lower power than Fairchild ■ Function and pinout compatible with Fairchild F100K ■ Available in 24-pin CERPACK and 28-pin PLCC packages The SY100S371 is an ultra-fast triple 4-input multiplexer with true and complementary outputs designed for use in high-performance ECL systems. The multiplexer is controlled by common select inputs S0 and S1. A logic HIGH on the Enable (E) control input takes the outputs to a logic LOW. The inputs on the device have 75KΩ pulldown resistors.
