74LVQ158MTR

74LVQ158TTR

ideal for low power and low noise 3.3V

applications.

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 high. 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.
