COMPATIBLE BUS SWITCH
IDTQS316245
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• 5Ω bidirectional switches connect inputs to outputs
• Pin compatible with FCT16245
• Flowthrough pinout for easy layout
• Zero propagation delay, zero ground bounce
• TTL-compatible input and output levels
• Undershoot clamp diodes on all switch and control inputs
• Available in SSOP package
DESCRIPTION:
The QS316245 provides a set of 16 high-speed CMOS TTL-compatible
bus switches (two banks of 8 switches each) in a flow-thru pinout. The low
ON resistance of the QS316245 allows inputs to be connected to outputs
without adding propagation delay and without generating additional ground
bounce noise. The Output Enable (OEx) signal turns the switches on similar
to the OEx signal of the 74’245. The QS316245 is ideally suited for 5V to
3.3V translation, bus switching and isolation, and hot insertion.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
APPLICATIONS:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Bus switching, isolation
• Power conservation, clock gating
• Logic replacement
