• Manufacturer Part Number: cbt6820
• Description: 20-bit Bus Switch With Precharged Outputs And Schottky Undershoot Protection For Live Insertion
• Manufacturer: NXP Semiconductors

1. All typical values are at VCC = 5V, TA = 25 C
2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On–state resistance is
4. Force I
