| Overview | The LS251 is a logical implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, S0, S 1, S2. Both assertion and negation outputs are . allows multiplexer expansion by tying the outputs of up to 128 devices together. When the outputs of the 3-state devices are tied together, all but one device must be in the high impedance state to avoid high currents that would exceed the maximum ratings. The Output Enable signals should be designe. |
