Product Overview

The SN74CB3Q3245PWR is a high-bandwidth FET Bus Switch utilizes 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 (I/O) ports. The device also features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus. It is specifically designed to support high-bandwidth applications. It is organized as an 8-bit bus switch with a single OE\ input. When OE\ is low, the 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 bus switch is OFF and a high-impedance state exists between the A and B ports. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry prevents damaging current backflow through the device when it is powered down.
  • Rail-to-rail switching on data I/O ports
  • Bidirectional data flow with near-zero propagation delay
  • Low input and output capacitance minimizes loading and signal distortion
  • Fast switching frequency
  • Data and control inputs provide undershoot clamp diodes
  • Low power consumption
  • Ioff Supports partial-power-down mode operation
  • Latch-up performance exceeds 100mA per JESD 78, Class II
  • Green product and no Sb/Br
