1 / 14 page SN74CBT6800A 10-BIT FET BUS SWITCH WITH PRECHARGED OUTPUTS SCDS005N – MARCH 1993 – REVISED MARCH 2001 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels D Outputs Are Precharged by Bias Voltage to Minimize Signal Distortion During Live Insertion description The SN74CBT6800A 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 SN74CBT6800A 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. When ON is high or VCC is 0 V, B port is precharged to BIASV through the equivalent of a 10-kΩ resistor.
