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
active-LOW Enable inputs. E1a will be tied to E1b and E2a
to E2b.
The auxiliary inputs (Hn) are used to determine whether
the outputs are active-HIGH or active-LOW. The address
inputs for the dual 1-of-4 mode are A0a, A1a, A0b. A2a is
unused. In the 1-of-8 mode, the address inputs are A0a,
A1a, A2a. The inputs on the device have 75k
pull-down
resistors.
