Functional Description
The ’F138 high-speed 1-of-8 decoder demultiplexer ac-
cepts three binary weighted inputs (A0 A1 A2) and when
enabled provides eight mutually exclusive active LOW out-
puts (O0 – O7) The ’F138 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
This multiple enable function allows easy parallel expansion
of the device to a 1-of-32 (5 lines to 32 lines) decoder with
just four ’F138 devices and one inverter (See Figure 1 ) The
’F138 can be used as an 8-output demultiplexer 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
