IDTQS3244 HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS3244 HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH FEATURES: DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc The QS3244 provides a set of eight high-speed CMOS TTL-compatible 5 bidirectional switches connect inputs to outputs bus switches in a pinout compatible with 74FCT244, 74F244, 74ALS/AS/ Pin compatible with 74F244, 74FCT244, and 74FCT244T LS244 8-bit drivers. The low ON resistance (5) of the 3244 allows inputs Zero propagation delay, zero ground bounce to be connected to outputs without adding propagation delay and without Undershoot clamp diodes on all switch and control inputs generating additional ground bounce noise. The two enable (xG) signals Available in QSOP, SOIC, and TSSOP packages turn the switches on similar to the xG signals of the 74244. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. The QS3244 is characterized for operation at -40C to +85C. APPLICATIONS: Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power conservation Capacitance reduction and isolation Logic replacement (data processing) Clock gating Bus switching and isolation FUNCTIONAL BLOCK DIAGRAM 1G 2G 1A1 1Y1 2A1 2Y1 1A2 1Y2 2A2 2Y2 1A3 1Y3 2A3 2Y3 2A4 1A4 1Y4 2Y4 INDUSTRIAL TEMPERATURE RANGE FEBRUARY 2011 1 c 2011 Integrated Device Technology, Inc.
