DESCRIPTION:
The QS3VH383 Bus Exchange HotSwitch with 10-bits is a high bandwidth
bus switch. The QS3VH383 has very low ON resistance, resulting in under
250pspropagationdelaythroughtheswitch. TheBusEnable(BE)signalturns
the switches on. The Bus Exchange (BX) signal provides nibble swap of the
AB and CD signal pairs. This exchange configuration allows byte swapping
of buses. In the OFF and ON states, the switches are 5V-tolerant. In the OFF
state, the switches offer very high impedence at the terminals.
The combination of near-zero propagation delay, the lack of additional
ground bounce noise, high OFF impedance, and over-voltage tolerance
makestheQS3VH383idealforhighperformancecommunicationsapplications.
The QS3VH383 is characterized for operation from -40°C to +85°C.
