DESCRIPTION

The SY100S370 is a universal demultiplexer/decoder

that can be used as either a dual 1-of-4 decoder or as a

single 1-of-8 decoder and is designed for use in high-

performance ECL systems. The Mode control (M) input

determines the function. In the dual 1-of-4 mode, each 4-

input group has a pair of active-LOW Enable (E) inputs.

The Enable pins are assigned such that in the single 1-of-

8 mode they can be tied together in pairs to result in two

the outputs are active-HIGH or active-LOW. The address

Ω pull-down

resistors.
