74FST3126 ON, 74FST3126 Datasheet - Page 4

• Manufacturer Part Number: 74FST3126
• Description: 4-Bit Bus Switch
• Manufacturer: ON

*Typical values are at V
6. Measured by the voltage drop between A and B pins at the indicated current through the switch.
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
