8-input Priority Encoders With 3-state Outputs , Inc

The SN54/74LS348 and the SN54/74LS848 are eight input priority encod- ers which provide the 8-line to 3-line function. The outputs (A0A2) and inputs (07) are active low. The active low input which has the highest priority (input 7 has the highest) is represented on the outputs (output A0 is the lowest bit). An example would be if inputs 1, 2 and 4 were low, then a binary 4 would be represented on the outputs. The GS (Group Signal) output is active low when any of the inputs are low. It serves to indicate when any of the inputs are active. A0, A1 and A2 are three-state outputs. This allows for up to 64 line expan- sion without the need for special external circuitry.
