资 源 简 介

The SN74CBT16800 provides 20 bits of high-speed TTL-compaTIble bus switching. The low on-state resistance of the switch allows connecTIons to be made with minimal propagaTIon delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-inserTIon noise. The device is organized as dual 10-bit bus switches with separate output-enable (OE) inputs. It can be used as two 10-bit bus switches or one 20-bit bus switch. When OE is low, the associated 10-bit bus switch is on and port A is connected to port B. When OE is high, the switch is open, the high-impedance state exists between the two ports, and port B is precharged to BIASV through the equivalent of a 10-k resistor.
