![]() ![]() The “zero” is encoded when all nine data inputs are HIGH, forcing all four outputs HIGH. These devices provide the 10-line to 4-line priority encoding function by use of the implied decimal “zero”. Featured by Sharvi Electronics A priority is assigned to each input so that when two or more inputs are simultaneously active, the input with the highest priority is represented on the output, with input line l9 having the highest priority. Decimal to bcd priority encoder k map code Encoders convert 2 N lines of input into a code of N bits and Decoders decode the N bits into 2 N lines.ncoders - An encoder is a combinational circuit that converts binary information in the form of a 2 N input lines into N output lines, which represent N bit code for the input. The ’HC147 and CD74HCT147 9-input priority encoders accept data from nine active LOW inputs (l1 to l9) and provide binary representation on the four active LOW inputs (Y0 to Y3). ![]() 74HC147 Decimal to BCD Priority Encoder IC DIP-16 Packageħ4HC147 (74147) IC–Priority Encoder The ’HC147 and CD74HCT147 are high-speed silicon-gate CMOS devices and are pin-compatible with low power Schottky TTL (LSTTL).
