SN74CB3Q32245 is 32-bit BUS SWITCH manufactured by Texas Instruments.
description
/ordering information
The SN74CB3Q32245 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allows for minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports. The device also features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus. Specifically designed to support high-bandwidth applications, the SN74CB3Q32245 provides an optimized interface solution ideally suited for broadband munications, networking, and data-intensive puting systems.
The SN74CB3Q32245 is organized as four 8-bit bus switches with separate output-enable (1OE, 2OE, 3OE, 4OE) inputs. It can be used as four 8-bit bus switches, two 16-bit bus switches, or as one 32-bit bus switch. When OE is low, the associated 8-bit bus switch is ON and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is high, the associated 8-bit bus switch is OFF, and a high-impedance state exists between the A and B ports.
