20-Bit FET Bus Switch
The SN74CBTR16861 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 is organized as one dual 10-bit Switch with separate output-enable (OE) inputs. When OE is low, the Switch is on, and port A is connected to port B. When OE is high, the Switch is open, and the high-impedance state exists between the two ports.
The device has equivalent 25- series resistors to reduce signal-reflection noise. This eliminates the need for external terminating resistors.
