DESCRIPTION

The M74HC148 is an high speed CMOS 8 TO 3

LINE PRIORITY ENCODER fabricated with

silicon gate C MOS technology.

has been provided to allow octal expansion

without the need for external circuitry. Data inputs

are active at the low logic level.

The M74HC148 encodes eight data lines to

three-line (4-2-1) binary (octal). Cascading

circuitry (enable input EI and enable output EO)

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
