Overview
The MC14504B, produced by onsemi, is a hex non-inverting level shifter that utilizes CMOS technology. This component is designed to shift TTL signals to CMOS logic levels, accommodating CMOS supply voltages ranging from 5 to 15 volts. It also features a control input that enables level translation between different CMOS logic levels by adjusting the power supply levels VDD and VCC. The VCC level determines the input signal levels, while VDD sets the output voltage levels.
