NOTES: 1. Typical values are at VCC = 5V and TA = 25°C. 2. RON is guaranteed but not production tested. 3. Pass voltage is guaranteed but not production tested.
NOTES: 1. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics. 2. Per TTL-driven input (VIN = 3.4V, control inputs only). A and Y pins do not contribute to ∆Icc. 3. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A and Y inputs generate no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.
Following Conditions Apply Unless Otherwise Specified: Industrial: TA = –40°C to +85°C, VCC = 5V ± 5%

IDTQS3125 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ENABLES INDUSTRIAL TEMPERATURE RANGE
APPLICATIONS:
• • • •
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
The QS3125 provides a set of four high-speed low resistance CMOS switches connecting inputs to outputs without propagation delay and without generating additional ground bounce noise. Individual enables (OE) are used to turn on the switches. The QS3125 is ideal for signal and control switching since the device adds no noise, ground bounce, propagation delay, or significant power consumption to the system. The QS3125 can also be used for analog switching applications such as video. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. The QS3125 is characterized for operation at -40°C to +85°C.
