SN74CBTS6800

SN74CBTS6800 10-BIT FET BUS SWITCH WITH PRECHARGED OUTPUTS AND SCHOTTKY DIODE CLAMPING SCDS102C – JUNE 1999 – REVISED OCTOBER 2000 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 D Schottky Diodes on the I/Os to Clamp Undershoots up to –2 V description The SN74CBTS6800 provides ten bits of high-speed TTL-compatible bus switching with Schottky diodes on the I/Os to clamp undershoots. 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.

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.
