The CD4019BM CD4019BC is a complementary MOS quad AND-OR select gate Low power and high noise margin over a wide voltage range is possible through implementation of N- and P-channel enhancement mode transistors These complementary MOS (CMOS) transistors provide the building blocks for the 4 ``AND-OR select'' gate configurations each consisting of two 2-input AND gates driving a single 2-input OR gate Selection is accomplished by control bits KA and KB All inputs are protected against static discharge damage
