8-input priority encoder
HEF4532B
MSI
DESCRIPTION
The HEF4532B is an 8-input priority encoder with eight
active HIGH priority inputs (I0 to I7), three active HIGH
outputs (O0 to O2), an active HIGH enable input (Ein), an
active HIGH enable output (Eout) and an active HIGH
group select output (GS).
Data is accepted on inputs I0 to I7. The binary code
corresponding to the highest priority input (I0 to I7) which is
HIGH, is generated on O0 to O2 if Ein is HIGH. Input I7 is
assigned the highest priority.
GS is HIGH when one or more priority inputs and Ein are
HIGH. Eout is HIGH when I0 to I7 are LOW and Ein is HIGH.
Ein, when LOW, forces all outputs (O0 to O2, GS, Eout)
LOW.
