A10964 - CD74HCT257E Quad 2-Input Multiplexer (Harris)

item number: A10964
unit price:£1.00 

Detailed Description

The CD74HCT257E is a quad 2-input multiplexer which selects 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. Moving data from two groups of registers to four common output buses is a common use of the 257. The state of the Select input determines the particular register from which the data comes. It can also be used as a function generator.
