QS3126 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ACTIVE INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ACTIVE HIGH ENABLES FEATURES: • • • • • • QS3126 DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc Bidirectional switches connect inputs to outputs Pin compatible with the 74’126 function Zero propagation delay, zero ground bounce Undershoot clamp diodes on all switch and control inputs Available in QSOP and SOIC packages The QS3126 provides a set of four high-speed CMOS switches connecting inputs to outputs. The low ON resistance of the QS3126 allows inputs to be connected to outputs without propagation delay and without generating additional ground bounce noise. Individual active high enables (OE) are used to turn the switches on. The QS3126 is ideal for signal and control switching since the device adds no noise, ground bounce, propagation delay, or significant power consumption to the system. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. The QS3126 is characterized for operation at -40°C to +85°C. APPLICATIONS: • • • • • Active high enabling Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power conservation Capacitance reduction and isolation (mass storage, work stations) • Logic replacement (data processing) • Clock gating • Bus isolation FUNCTIONAL BLOCK DIAGRAM 1A 2A 3A 4A 1Y 2Y 3Y 4Y 1OE 2OE 3OE 4OE INDUSTRIAL TEMPERATURE RANGE MAY 2019 1 c 2019 Integrated Device Technology, Inc.

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 0.25ns at 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 QS3126 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ACTIVE 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 S1 Quarter Size Outline Package (PCG16) Small Outline IC (DCG14) 3126 High Speed CMOS Quadruple Bus Switch with Individual Active High Enables Orderable Part Information Speed (ns) Pkg.
