SN74CBTS6800

10-BIT FET BUS SWITCH

WITH PRECHARGED OUTPUTS AND SCHOTTKY DIODE CLAMPING

POST OFFICE BOX 655303

Minimize Signal Distortion During Live

Insertion

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.

The SN74CBTS6800 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.
