CD74HC147
- Buffered inputs and outputs
- Typical propagation delay: 13ns at VCC = 5V, CL = 15pF, TA = 25oC
- Fanout (over temperature range)
- Bus driver outputs: 15 LSTTL loads
- Wide operating temperature range: -55oC to 125oC
- Balanced propagation delay and transition times
- Significant power reduction compared to LSTTL logic ICs
- HC types
- 2V to 6V Operation
- High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
- HCT types
- 4.5V to 5.5V Operation
- Direct LSTTL input logic compatibility, VIL= 0.8V (Max), VIH = 2V (Min)
- CMOS input compatibility, Il ≤ 1µA at VOL, VOH
The CDx4HC147 and CD74HCT147 are 9-input priority encoders. These devices provide the 10-line to 4-line priority encoding function by use of the implied decimal “zero.”
