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
