INTEGRATED CIRCUITS CBT6800 10-bit bus switch with precharged outputs for live insertion Product data Supersedes data of 1999 Oct 28 Philips Semiconductors 2003 Sep 12
Philips Semiconductors Product data 10-bit bus switch with precharged outputs for live insertion FEATURES CBT6800 DESCRIPTION • 5 Ω switch connection between two ports • TTL compatible input and output levels • Outputs are precharged by bias voltage to minimize signal The CBT6800 provides ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows bi-directional connections to be made while adding near-zero propagation delay.
