CD4504 – Hex Voltage-Level Shifter IC
The CD4504 hex voltage level shifter IC consists of six circuits that shift input signals from the VCClogic level to the VDDlogic level. To shift TTL signals to CMOS logic levels, the SELECT input is at the VCCHIGH logic state. When the SELECT input is in a LOW logic state, each circuit translates signals from one CMOS level to another.
The CD4504 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, and MT suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
