SN74CBT16210 20-Bit FET Bus Switch |

SN74CBT16210 (ACTIVE) 20-Bit FET Bus Switch

20-Bit FET Bus Switch - SN74CBT16210


The SN74CBT16210 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 a dual 10-bit bus switch with separate output-enable (OE\) inputs. It can be used as two 10-bit bus switches or as 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, and the high-impedance state exists between the ports.
