32-Bit FET Bus Switch (Rev. C)
Texas Instruments
Description
The SN74CBT34X245 provides 32 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 four 8-bit bus switches, two 16-bit bus switches, or one 32-bit bus switch. When output enable (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. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
