FEATURES
DESCRIPTION
■ 725ps max. D to output
The SY10/100E171 offer three 4:1 multiplexers with
differential outputs, designed for use in new, high-
performance ECL systems. The leading 4-bit multiplexer
operation is organized pairwise, with each pair being a 2-
bit 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.
■ Extended 100E VEE range of –4.2V to –5.5V
■ Differential outputs
■ Split select architecture
■ Fully compatible with industry standard 10KH,
100K ECL levels
■ Internal 75KΩ input pulldown resistors
■ Fully compatible with Motorola MC10E/100E171
■ Available in 28-pin PLCC package
