Overview
The MC14504BFELG is a hex non-inverting level shifter produced by onsemi, utilizing CMOS technology. This component is designed to shift TTL (Transistor-Transistor Logic) signals to CMOS (Complementary Metal-Oxide-Semiconductor) logic levels, and it can also translate between different CMOS logic levels. The device operates over a wide range of supply voltages, from 5 to 15 volts, making it versatile for various applications. It features a control input that allows for either up or down level translation by selecting the appropriate power supply levels (VDD and VCC).
