Logic device/transceiver/encoder

The MC14504B is a six-way non-inverting level shifter using CMOS process. The level shifter converts TTL signals to CMOS logic levels for any CMOS supply voltage between 5 and 15 V. The control input also allows interfacing from CMOS at one logic level to CMOS at another logic level: Up or down level translation will be achieved by selecting the supply levels VDD and VCC. The VCC level sets the input signal level, while VDD selects the output voltage level.
