| Micrel, Inc. 3-BIT 4:1 MULTIPLEXER SY10E171 SY100E171 SY10E171 SY100E171 FEATURES s s s s s 725ps max. D to output Extended 100E VEE range of -4.2V to -5.5V Differential outputs Split select architecture Fully compatible with industry standard 10KH, 100K ECL levels s Internal 75K input pulldown resistors s Fully compatible with Motorola MC10E/100E171 s Available in 28-pin PLCC package DESCRIPTION The SY10/100E171 offer three 4:1 multiplexers with differential outputs, designed for use in new, highperformance ECL systems. The leading 4-bit multiplexer operation is organized pairwise, with each pair being a 2bit multiplexer. Separate select (SEL1A, SEL1B) controls are provided within each pair. The SEL1A and SEL1B signals control the leading multiplexers, while the SEL2 signal controls the output multiplexer. The three select signals can be used to determine which of the four data inputs will be propagated to the corresponding outputs.
