QS32245 HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH DESCRIPTION: FEATURES: • • • • • • • • • QS32245 The QS32245 provides a set of eight high-speed CMOS TTL-compatible bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/ LS245 8-bit transceivers. The Output Enable (OE) signal turns the switches on similar to the OE signal of the 74’245. The QS32245 has 25Ω series resistors to reduce ground bounce noise. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. The QS32245 is characterized for operation at -40°C to +85°C. Enhanced N channel FET with no inherent diode to Vcc Ω bidirectional switches connect inputs to outputs 5Ω Pin compatible with the 74F245, 74FCT245, and 74FCT245T Low power CMOS proprietary technology Zero propagation delay, zero ground bounce Undershoot clamp diodes on all switch and control inputs Ω resistors for low noise 25Ω TTL-compatible control inputs Available in QSOP and TSSOP packages 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 B0 B1 B2 B3 B4 B5 B6 B7 OE INDUSTRIAL TEMPERATURE RANGE JUNE 2019 1 c 2019 Integrated Device Technology, Inc.

Unit — — 1.25 ns 0.5 — 6.6 ns 0.5 — 4.5 ns NOTES: 1. Minimums are guaranteed but not production tested. 2. This parameter is guaranteed but not production tested. 3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 1.25ns for CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 4 QS32245 HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION QS XXXXX Device Type XX Package X Process X X Blank 8 Tube Tape and Reel Blank Industrial (-40°C to +85°C) G Green Q PA Quarter Size Outline Package (PCG20) Thin Shrink Small Outline Package (PGG20) 32245 High Speed CMOS Quickswitch 8-Bit Bus Switch Orderable Part Information Pkg.
