SN74LS147, SN74LS148
10−Line−to−4−Line and 8−Line−to−3−Line Priority Encoders
The SN74LS147 and the SN74LS148 are Priority Encoders. They provide priority decoding of the inputs to ensure that only the highest order data line is encoded. Both devices have data inputs and outputs which are active at the low logic level.
The LS147 encodes nine data lines to f...
