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
