ADVANCE INFORMATION
DESCRIPTION
The QS3862 and QS32862 each provide a set of ten high speed CMOS, TTL Compatible bus switches. The low ON resistance (5) of the QS3862 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The switches are controlled by independent active Low enable (BE) and active High enable (BE) controls. The QS32862 includes internal 25 series termination resistors to reduce reflection noise in high speed applications. When closed, the switch acts as the source (series) termination for the driver connected to it. The QS3862 is ideal for switching digital buses as well as hotplugging, hot-docking, and voltage translation.
APPLICATIONS
· Hot-swapping, hot-docking (Application Note AN-13) · Voltage translation (5V to 3.3V; Application Note AN-11) · Power conservation · Capacitance reduction and isolation · Applications requiring Active-High enabling · Bus isolation · Clock gating
