This product is a 10-bit bus switch with precharged outputs for live insertion
The Philips CBT6800 is a 10-bit high-speed TTL-compatible bus switch featuring precharged outputs to minimize signal distortion during live insertion. It connects two ports (A and B) with a single enable input, allowing bi-directional connections with near-zero propagation delay. When the switch is disabled, the B port is precharged to a user-selectable bias voltage (BIASV) via a 10 kΩ equivalent resistor.
The device is characterized for operation from -40°C to +85°C and is available in a 24-pin Plastic TSSOP package. Key features include latch-up protection exceeding 100 mA and ESD protection exceeding 2000 V HBM. The datasheet provides absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, and package dimensions.
| Number of bits | 10-bit |
|---|---|
| Operating temperature range | -40°C to +85°C |
| Package type | 24-Pin Plastic TSSOP |
| Latch-up protection | exceeds 100 mA |
| ESD protection (HBM) | exceeds 2000 V |
The outputs are precharged by a bias voltage to minimize signal distortion during live insertion.
When the enable input is high, the switch between port A and port B is open, and the B port is precharged to the bias voltage.
