Functional Description
The ’AC/’ACT138 high-speed 1-of-8 decoder/demultiplexer
accepts three binary weighted inputs (A
0,A1,A2) and, when
enabled, provides eight mutually exclusive active-LOW out-
puts (O
0–O7). The ’AC/’ACT138 features three Enable in-
puts, two active-LOW (E
1,E2) and one active-HIGH (E3). All
outputs will be HIGH unless E
1 and E2 are LOW and E3 is
HIGH. This multiple enable function allows easy parallel ex-
pansion of the device to a 1-of-32 (5 lines to 32 lines) de-
coder with just four ’AC/’ACT138 devices and one inverter
(see
Figure 1). The ’AC/’ACT138 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.
