PRIORITY ENCODER
The MC54/74F148 provides three bits of binary coded output representing
the position of the highest order active input, along with an output indicating
the presence of any active input. It is easily expanded via input and output en-
ables to provide priority encoding over many bits.
Encodes Eight Data Lines in Priority
Provides 3-Bit Binary Priority Code
Input Enable Capability
Signals When Data Present on Any Input
Cascadable for Priority Encoding of n Bits
