Datasheet Summary
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 = 14.5 ns typ (CL = 50 pF)
- High Output Current: Fanout of 10 LSTTL Loads
- Wide Operating Voltage: VCC = 2 to 6 V
- Low Input Current: 1 µA max
- Low Quiescent Supply...
