Pin Descriptions
Functional Description
The LCX138 high-speed 1-of-8 decoder/demultiplexer
accepts three binary weighted inputs (A0, A1, A2) and,
when enabled, provides eight mutually exclusive active-
LOW outputs (O0–O7). The LCX138 features three Enable
inputs, two active-LOW (E1, E2) and one active-HIGH (E3).
All outputs will be HIGH unless E1 and E2 are LOW and E3
is HIGH. The LCX138 can be used as an 8-output demulti-
plexer by using one of the active LOW Enable inputs as the
data input and the other Enable inputs as strobes. The
Enable inputs which are not used must be permanently tied
to their appropriate active-HIGH or active-LOW state.
