• Manufacturer Part Number: 74fst3861
• Description: 10bit Bus Switch
• Manufacturer: ON Semiconductor

5. Unused control inputs may not be left open. All control inputs must be tied to a high or low logic input voltage level.
*Typical values are at V
6. Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance is determined by the lower
7. This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay other than the RC delay of the
