IDTQS3245 HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS3245 HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH FEATURES: DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc The QS3245 provides a set of eight high-speed CMOS TTL-compatible 5 bidirectional switches connect inputs to outputs bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/ Pin compatible with the 74F245, 74FCT245, and 74FCT245T LS245 8-bit transceivers. The low ON resistance of the QS3245 allows Low power CMOS proprietary technology inputs to be connected to outputs without adding propagation delay and Zero propagation delay, zero ground bounce without generating additional ground bounce noise. The Output Enable Undershoot clamp diodes on all switch and control inputs (OE) signal turns the switches on similar to the OE signal of the 74245. TTL-compatible control inputs QuickSwitch devices provide an order of magnitude faster speed than Available in SOIC and QSOP packages conventional logic devices. The QS3245 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 A0 A1 A2 A3 A4 A5 A6 A7 OE B0 B1 B2 B3 B4 B5 B6 B7 INDUSTRIAL TEMPERATURE RANGE NOVEMBER 2014 1 c 2014 Integrated Device Technology, Inc.
