DESCRIPTION The M54HC148 is an high speed CMOS 8 TO 3 LINE PRIORITY ENCODER fabricated with silicon gate C2MOS technology.

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. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
