DESCRIPTION
PIN CONNECTION AND IEC LOGIC SYMBOLS It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption. It consists of four 2-input digital multiplexers with common select and strobe inputs. When strobe input is held high selection of data is inhibit and all the outputs become low. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
