DUAL 8-INPUT MULTIPLEXER Micrel, Inc. SY100S363 SY100S363 DESCRIPTION FEATURES ■ ■ ■ ■ The SY100S363 is a dual 8-input multiplexer designed for use in new, high-performance ECL systems. The three Data Select inputs (S 0 , S 1 , S 2 ) determine the bits from each of the inputs (A n , B n ) 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 75kΩ pull-down resistors. 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 75kΩ input pull-down resistors ■ 60% faster than Fairchild 300K at lower power ■ Function and pinout compatible with Fairchild F100K ■ Available in 28-pin PLCC packages BLOCK DIAGRAM A7 A6 A5 PIN NAMES A4 Pin Za A3 Function S0 – S2 Data Select Inputs A0 – A7 A Data Inputs B0 – B7 B Data Inputs Za, Zb Data Outputs A0 VEES VEE Substrate S2 VCCA VCCO for ECL Outputs S1 A2 A1 S0 B7 B6 B5 B4 Zb B3 B2 B1 B0 M9999-042307 [email protected] or (408) 955-1690 Rev.: I 1 Amendment: /0 Issue Date: April 2007 SY100S363 Micre, Inc.
