The Harris CD74HC257 and CD74HCT257 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select Input (S). The Output Enable input (OE) is active LOW. When OE is HIGH, all of the outputs (1Y-4Y) are in the high impedance state regardless of all other input conditions. |
