资 源 简 介
The SN74CBTK6800 device provides ten bits of high-speed TTL-compaTIble bus switching. The low on-state resistance of the switch allows bidirecTIonal connecTIons to be made while adding near-zero propagaTIon delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise.
The A and B ports have an active-clamp undershoot-protection circuit. When there is an undershoot, the active-clamp circuit is enabled and current from VCC is supplied to clamp the output, preventing the pass transistor from turning on.
The SN74CBTK6800 is organized as one 10-bit switch with a single enable (ON) input. When ON is low, the switch is on, and port A is connected to port B. When ON is high, the switch between port A and port B is open.
