share this product
Description
74LS147 The TTL 74LS147 is a 10-line to 4-line and 8-line to 3-line inputs to ensure that only the highest order of the data line is encoded. This device has data inputs and outputs that are active at the low logic level.
The LS147 encodes nine lines of data to four lines (8-4-2-1) BCD. The implicit of the zero decimal condition does not require an input condition because zero is encoded when all nine data lines are at a high logical level.
