8-Line to 3-Line Priority Encoder
74F148 8-Line to 3-Line Priority Encoder April 1988 Revised September 2000 74F148 8-Line to 3-Line Priority Encoder General Description Features The F148 provides three bits of binary coded output repre-Encodes eight data lines in priority senting the position of the highest order active input, alongProvides 3-bit binary priority code with an output indicating the presence of any active input. It Input enable capability is easily expanded via input and output enables to provide Signals when data is present on any input priority encoding over many bits. Cascadable for priority encoding of n bits Ordering Code: Order Number Package Number Package Description 74F148SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74F148SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F148PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
