HD74HC147
10-to-4-line Priority Encoder
REJ03D0572-0200 (Previous ADE-205-446)
Rev.2.00 Oct 11, 2005
Description
The HD74HC147 features priority encoding of the inputs to ensure that only the highest order data line is encoded. Nine input lines are encoded to a four line BCD output. The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level. All data inputs and outputs are active at the low logic level.
Features
• High Speed Operation: tpd = 14.
