Overview
The MC14049BCP, produced by onsemi, is a Hex Inverter/Buffer integrated circuit. It is constructed with MOS P−Channel and N−Channel enhancement mode devices in a single monolithic structure. This component is designed for applications where low power dissipation and high noise immunity are crucial. It provides logic level conversion using a single supply voltage, VDD, and can drive two TTL/DTL loads when used as a CMOS−to−TTL/DTL converter.
