HIGH. This multiple enabled function allows easy parallel
expansion of the device to a 1−of−32 (5 lines to 32 lines)
decoder with just four MC74AC138/74ACT138 devices
and
MC74AC138/74ACT138 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.
