SN74CBTR16861 20 位 FET 总线开关
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
