Overview
The MC14050BDT, produced by Onsemi, is a Noninverting Hex Buffer constructed with MOS P-Channel and N-Channel enhancement mode devices in a single monolithic structure. These complementary MOS devices are primarily used in applications where low power dissipation and/or high noise immunity are desired. The device provides logic level conversion using only one supply voltage, VDD, and can drive two TTL/DTL loads when used as a CMOS-to-TTL/DTL converter.
