General Description

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.” PART NUMBER CD54HC147 CD74HC147 CD74HCT147 Device Information PACKAGE(1) BODY SIZE (NOM)(2) J (CDIP, 16) 21.34mm × 6.92mm N (PDIP, 16) 19.31mm × 6.35mm D (SOIC, 16) 9.90mm × 3.90mm PW (TSSOP, 16) 5.00mm × 4.40mm N (PDIP, 16) 19.31mm × 6.35mm (1) For more information, see Mechanical, Packaging, and Orderable Information.
