Overview
The CD4504BM is a CMOS hex voltage-level shifter produced by Texas Instruments. This component consists of six circuits designed to shift input signals from one logic level to another, specifically from the VCC logic level to the VDD logic level. It is capable of shifting TTL signals to CMOS logic levels and can also translate signals between different CMOS levels. The device is available in various package types, including SOIC-16, PDIP, CDIP, and TSSOP, making it versatile for different application requirements.
