SEMICONDUCTOR TECHNICAL DATA
MC14558B BCD-to-Seven Segment Decoder
The MC14558B decodes 4- bit binary coded decimal data dependent on the state of auxiliary inputs, Enable and RBI, and provides an active- high seven- segment output for a display driver. An auxiliary input truth table is shown, in addition to the BCD to seven- segment truth table, to indicate the functions available with the two auxiliary inputs. Leading Zero blanking is easily obtained with an external flip- flop in time division multiplexed systems displaying most significant decade first.
