The SNx4HC257 and ’258 contain four data selectors/ multiplexers to select one of two data sources. All channels are controlled by the same address select (A/B) input, and active-low strobe (G) input. A high level at the G terminal forces all outputs into the high-impedance state. The ’257 has non-inverted outputs and the ’258 has inverted outputs.
