INDUSTRIAL TEMPERATURE RANGE
IDTQS32X245
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• 5Ω bidirectional switches connect inputs to outputs
• Dual '245 function
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• TTL-compatible control inputs
• Available in 40-pin QVSOP package
APPLICATIONS:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Bus switching and isolation
• Power conservation
• Clock gating
• Logic replacement
DESCRIPTION:
The QS32X245 provides a set of 16 high-speed CMOS TTL-compatible
bus switches in a flow-through pinout. The low ON resistance of the
QS32X245 allows inputs to be connected to outputs without adding propa-
gation delay and without generating additional ground bounce noise. 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 QS32X245 is characterized for operation at -40°C to +85°C.
