QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 10-BIT BUS SWITCH WITH FLOW-THROUGH PINOUT
.EATURES:
· · · · Enhanced N channel FET with no inherent diode to Vcc Near zero ground bounce Undershoot clamp diodes on all switch and control inputs Available in QSOP and SOIC packages
IDTQS32861
DESCRIPTION:
The QS32861 provides a set of ten high speed CMOS, TTL-compatible bus switches. The Bus Enable (BE) signal turns the switches on. The QS32861 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 QS32861 is characterized for operation at -40°C to +85°C.
APPLICATIONS:
· · · · · · Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power conservation Capacitance reduction and isolation Clock gating Bus isolation
