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

Name: 74147 10-to-4 Decimal to BCD Priority Encoder IC
SKU: IC0111
Price: 55.00 INR
Availability: InStock

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.
