Quad AND-OR Select Gate
General Description
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 Кд and Kb- All inputs are protected against static discharge damage.

Features
■ Wide supply voltage range - 3.0V to 15V
■ High noise immunity - 0.45 VDD (typ.)
■ Low power TTL compatibility - Fan out of 2 driving 74L or 1 driving 74LS

Applications
■ AND-OR select gating
■ Shift-right/shift-left registers
■ True/complement selection
■ AND/OR/EXCLUSIVE-OR seec.ci
