| QUAD 2:1 MULTIPLEXER SY10E157 SY100E157 FEATURES s Individual select controls s Extended 100E VEE range of -4.2V to -5.5V s s s s 550ps max. D to Output 800ps max. SEL to Output Internal 75K input pull-down resistors Fully compatible with industry standard 10KH, 100K ECL levels s Available in 28-pin PLCC package DESCRIPTION The SY10/100E157 contain four 2:1 multiplexers with differential outputs. The output data are controlled by the individual Select (SEL) inputs. The individual select control makes the devices well suited for random logic designs.
