Effects
The ITT9309 is a monolithic, high speed, dual
four-input digital multiplexer circuit, constructed
with a planar epitaxial process. It
consists of two multiplexing circuits with
common input select logic, each circuit
contains four inputs and fully buffered
complementary outputs. In addition to operating
as a multiplexer, the ITT9309 can generate
any two functions of three variables. Active
pullups in the outputs ensure high drive and
high speed performance. Because of its high
speed performance and on-chip select decoding,
the ITT9309 may be cascaded to multiple
levels so that any number of lines can be
multiplexed onto a single output buss. The
circuit uses TTL for high speed, high fanout
operation and is compatible with all DTL, and
TTL digital integrated circuits.
