Download the SN74LS258B datasheet PDF. This datasheet also covers the SN74LS257B variant, as both devices belong to the same quad 2-input multiplexer family and are provided as variant models within a single manufacturer datasheet.
The LS257B and LS258B are Quad 2-Input Multiplexers with 3-state outputs.
They select four bits of data from two sources each under control of a Common Data Select Input.
When the Select Input is LOW, the I0 inputs are selected and when Select is HIGH, the I1 inputs are selected.
