DESCRIPTION
CD4504B hex voltage level-shifter consists of six circuits which shift input signals from the VCC logic level to the
VDD logic level. To shift TTL signals to CMOS logic levels, the SELECT input is at the VCC HIGH logic state.
When the SELECT input is at a LOW logic state, each circuit translates signals from one CMOS level to another.
