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 24-pin CERPACK and 28-pin PLCC packages B6 B5 B4 ■ ■ ■ ■ SY100S363 S0 B7 B6 B5 B4 B3 Zb B2 B1 B0 Rev.: G 1 Amendment: /0 Issue Date: July, 1999 SY100S363 Micrel PIN NAMES Pin Function S0 – S2 Data Select Inputs A0 – A7 A Data Inputs B0 – B7 B Data Inputs Za, Zb Data Outputs VEES VEE Substrate VCCA VCCO for ECL Outputs TRUTH TABLE(1) Inputs Select Data S2 S1 S0 L L L L L L L L L L H H L L H H L L L L H H H H H H L L L L H H L L H H H H H H L L H H H H H H A7/B7 A6/B6 A5/B5 A4/B4 Outputs A3/B3 A2/B2 A1/B1 L H L H L H L H L H A0/B0 Za/Zb L H L H L H L H L H L H L H L H L H L H L H NOTE: 1.
