SN74CBTD16211DGGR

FET BUS SWITCH, 24BIT, TSSOP-56.

The SN74CBTD16211DGGR is a 24-bit FET Bus Switch with level shifting. It provides 24-bit of high-speed TTL-compatible bus switching. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay. A diode to VCC is integrated in the circuit to allow for level shifting from 5V signals at the device inputs to 3.3V signals at the device outputs. The device is organized as a dual 12-bit bus switch with separate OE\ inputs. It can be used as two 12-bit bus switches or as one 24-bit bus switch. When OE\ is low, the associated 12-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.
