Overview
The MC14504B, specifically the MC14504BDTR2, is a hex non-inverting level shifter produced by onsemi. This device utilizes CMOS technology to shift TTL (Transistor-Transistor Logic) signals to CMOS (Complementary Metal-Oxide-Semiconductor) logic levels. It is designed to operate with CMOS supply voltages ranging from 5 to 15 volts and can also translate between different CMOS logic levels by adjusting the power supply levels VDD and VCC.
