74HC148 - 8 TO 3 LINE PRIORITY ENCODER

General Description

The M54/74HC148 is a high speed CMOS 8-TO-3 LINE PRIORITY ENCODER fabricated in silicon gate C2MOS technology.

It has the same high speed performance for LSTTL combined with true CMOS low power consumption.

The M54/74HC148 encodes eight data lines to three-line (4-2-1) binary (octal).
