IDTQS3125
DESCRIPTION:
Enhanced N channel FET with no inherent diode to Vcc
Pin compatible with the 74’125 function
Zero propagation delay, zero added ground bounce
Undershoot clamp diodes on all switch and control inputs
Available in QSOP and SOIC packages
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.

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 0.25ns at C
L
= 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.
