8-input multiplexer with 3-state output
DESCRIPTION
The HEF4512B is an 8-input multiplexer with 8 binary
inputs (I0 to I7), an enable input (E) and an output enable
input (EO). One of eight binary inputs is selected by select
inputs S0, S1 and S2, and is routed to the output O. A HIGH
on EO causes O to assume a high impedance OFF-state,
regardless of other input conditions. This allows the output
to interface directly with bus oriented systems (3-state).
When the active LOW enable (E) is HIGH, it forces the
output LOW provided EO is LOW. By proper manipulation
of the inputs, the device can provide any logic functions of
four variables. It cannot be used to multiplex analogue
signals.
