The MC14504B is a hex non−inverting level shifter using CMOS technology. The level shifter will shift a TTL signal to CMOS logic levels for any CMOS supply voltage between 5 and 15 volts. A control input also allows interface from CMOS to CMOS at one logic level to another logic level: Either up or down level translating is accomplished by selection of power supply levels VDD and VCC. The VCC level sets the input signal levels while VDD selects the output voltage levels.
