MC14049BDG Description

The MC14049BDG from onsemi is a hex inverter buffer belonging to the 4000B series, designed for high-performance logic inversion in a 16-SOIC surface-mount package. Operating across a wide voltage range (3V to 18V), it offers robust performance with a maximum propagation delay of 60ns at 15V and 50pF load. This ROHS3-compliant device features six independent inverters, each with a single input, making it ideal for signal conditioning, level shifting, and waveform generation. With low quiescent current (4 µA max) and high output drive capability (10mA source, 40mA sink), it ensures efficient power management and reliable signal integrity in digital systems.
