The HCF4019B is a HCF4019B series quad AND/OR select gate consisting of four AND/OR select gates, each consisting of two 2-input AND gates driving a single 2-input OR gate. Selection is accomplished by control bits Ka and Kb. In addition to selection of either channel A or channel B information, the control bits can be applied simultaneously to accomplish the logical A+B function.
The HCF4019B is a monolithic integrated circuit available in DIP and SOP packages. It consists of four AND/OR select gate configurations, each comprising two 2-input AND gates driving a single 2-input OR gate. Selection between channels A or B, or the logical A+B function, is controlled by bits Ka and Kb.
