TechInfo 74148 M74HC148B1 / M74HC148, 8 TO 3 LINE PRIORITY ENCODER IC (PACK OF 1) Electronic Components Electronic Hobby Kit

The M74HC148 is an high speed CMOS 8 TO 3 LINE PRIORITY ENCODER fabricated with silicon gate C2MOS technology. The M74HC148 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.
