| Description | The LS157 is a Quad 2-Input Multiplexer fabricated with the Schottky barrier diode process for high speed. It selects four bits of data from two sources under the control of a common Select Input (S). The Enable Input (E) is active LOW. When E is HIGH, all of the outputs (Z) are forced LOW regardless of all other inputs. The LS157 is the logic implementation of a 4-pole, 2-position switch where th... |
