| DUAL 8-INPUT MULTIPLEXER SY100S363 FEATURES s s s s s s s s s Max. propagation delay of 900ps IEE min. of -92mA Industry standard 100K ECL levels Extended supply voltage option: VEE = -4.2V to -5.5V Voltage and temperature compensation for improved noise immunity Internal 75K input pull-down resistors 60% faster than Fairchild 300K at lower power Function and pinout compatible with Fairchild F100K Available in 24-pin CERPACK and 28-pin PLCC packages DESCRIPTION The SY100S363 is a dual 8-input multiplexer designed for use in new, high-performance ECL systems. The three Data Select inputs (S0, S1, S2) determine the bits from each of the inputs (An, Bn) that will be passed on through the two outputs. The same bit will be selected from the two groups of 8 inputs. The inputs on this device have 75K pull-down resistors.
