It consists of four 2-input digital multiplexer with common select and strobe inputs. It is an inverting multiplexer. When the STROBE input is held high selection of data is inhibit and all the outputs become high. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
