Overview

MM74HC148 8-3 Line Priority Encoder October 1987 Revised February 1999 MM74HC148 8-3 Line Priority Encoder General Description The MM74HC148 priority encoder utilizes advanced silicon-gate CMOS technology.
It has the high noise immunity and low power consumption typical of CMOS circuits, as well as the speeds and output drive similar to LB-TTL.
This priority encoder accepts 8 input request lines 0–7 and outputs 3 lines A0–A2.
The priority encoding ensures that only the highest order data line is encoded.
Cascading circuitry (enable input EI and enable output EO) has been provided to allow octal expansion without the need for external circuitry.
All data inputs and outputs are active at the...
