| 16:1 MULTIPLEXER SY10E164 SY100E164 FEATURES s 850ps Data Input to Output s Extended 100E VEE range of -4.2V to -5.5V s Differential output s Fully compatible with industry standard 10KH, 100K ECL levels s Internal 75K input pull-down resistors s Fully compatible with Motorola MC10E/100E164 s Available in 28-pin PLCC package DESCRIPTION The SY10/100E164 are 16:1 multiplexers with a differential output. The select inputs (SEL0,1,2,3) control which one of the sixteen data inputs (A0-A15) is propagated to the output. Special attention to the design layout results in a typical skew between the 16 inputs of only 50ps.
