CD74HC147 - 10- to 4-Line Priority Encoder

Datasheet Summary

Description

The CDx4HC147 and CD74HCT147 are 9-input priority encoders.

Features

  • 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 =.
