Overview
The CD4049UBPWR, produced by Texas Instruments, is a CMOS hex inverting buffer and logic-level converter. This device is part of the 4000/14000/40000 series and is designed to provide high-performance logic functions. It features six inverting buffers, each capable of converting CMOS logic levels to TTL or DTL levels using a single supply voltage (VCC). The CD4049UBPWR is available in various package types, including TSSOP, which is indicated by the 'PWR' suffix.
