Bus Switch 2-Element CMOS 20-IN 48-Pin TVSOP T/R

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-O series resistors to reduce signal-reflection noise. This eliminates the need for external terminating resistors.
