MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14558B BCD-to-Seven Segment Decoder The MC14558B decodes 4­bit binary coded decimal data dependent on the state of auxiliary inputs, Enable and RBI, and provides an active­high seven­segment output for a display driver. An auxiliary input truth table is shown, in addition to the BCD to seven­segment truth table, to indicate the functions available with the two auxiliary inputs. Leading Zero blanking is easily obtained with an external flip­flop in time division multiplexed systems displaying most significant decade first. · · · · · · Supply Voltage Range = 3.0 Vdc to 18 Vdc Segment Blanking for All Illegal Input Combinations Lamp Test Function Capability for Suppression of Non­Significant Zeros Lamp Intensity Function Capable of Driving Two Low­power TTL Loads.
