| Micrel, Inc. TRIPLE 4-INPUT MULTIPLEXER WITH ENABLE DESCRIPTION SY100S371 SY100S371 FEATURES s Max. propagation delay of 1000ps s IEE min. of -68mA s Industry standard 100K ECL levels s Extended supply voltage option: VEE = -4.2V to -5.5V s Voltage and temperature compensation for improved noise immunity s Internal 75k input pull-down resistors s 40% faster than Fairchild s 40% lower power than Fairchild s Function and pinout compatible with Fairchild F100K s Available in 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 75k pulldown resistors.
