.EATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• Dual '245 function
• 25Ω resistor for low noise
• Low propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• TTL-compatible control inputs
• Available in 40-pin QVSOP package
DESCRIPTION:
The QS32X2245 provides a set of 16 high-speed CMOS TTL-compatible
bus switches in a flow-through pinout. The QS32X2245 includes internal
25Ω resistors to reduce reflection noise in high speed applications. The
Output Enable (OEn) signals turn the switches on similar to the OEn signal
of the 74'245.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS32X2245 is characterized for operation at -40°C to +85°C.
APPLICATIONS:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Bus switching and isolation
• Power conservation
• Clock gating
• Logic replacement
