74147 10-to-4 Decimal to BCD Priority Encoder IC

SKU: IC0111

55.00

74147 datasheet specifies that this IC is a TTL encoder feature priority decoding of the inputs to ensure that only the highest-order data line is encoded. The decimal zero condition requires no input condition because zero is encoded when all 9 data lines are at a high logic level.
