• Manufacturer Part Number: cbt3125db
• Description: Cbt3125 Quadruple Fet Bus Switch
• Manufacturer: NXP Semiconductors

1. All typical values are at V
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
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
