IRRADIATION

The M54HC148 encodes eight data lines to

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

circuitry (enable input EI and enable output EO)

has been provided to allow octal expansion

without the need for external circuitry. Data inputs

are active at the low logic level.

■

DEVICE FULLY COMPLIANT WITH

SCC-9410-017

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

DESCRIPTION

The M54HC148 is an high speed CMOS 8 TO 3

LINE PRIORITY ENCODER fabricated with

silicon gate C MOS technology.
