CBT3857; 10-bit bus switch with 10 kOhm pull-down termination registers
| Description |  |
This 10-bit bus switch is designed for 3 V to 3.6 V VCC operation and SSTL_2 output enable (OE) input levels. When OE is LOW, the 10-bit bus switch is on and port A is connected to port B. When OE is HIGH, the switch is open, and a high-impedance state exists between the two ports. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The CBT3857 is characterized for operation from 0°C to +85°C.
| Features | |
- Enable signal is SSTL_2 compatible
