Enhanced N channel FET with no inherent diode to Vcc
Zero propagation delay, zero ground bounce
TTL-compatible input and output levels
Undershoot clamp diodes on all switch and control pins
Available in 56-pin SSOP and TSSOP Packages
The QS3162233 is a 32-bit to 16-bit high-speed CMOS, TTL-compatible
switch which can multiplex or demultiplex data. It can be used for memory
interleaving where two memory banks need to be addressed simultaniously.
It can also be used as two 16-bit to 8-bit multiplexers or as one 32-bit to 16bit multiplexer. SELn inputs control the data flow. TESTn inputs control either
one or two ports connection. The QS3162233 adds an internal 25Ω series
termination resistor to each switch to reduce reflection noise in high-speed
applications.

2. Per TLL driven input (VIN = 3.4V). A and B 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 B inputs generate no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.

NOTES:
1. Minimums are guaranteed but not production tested.
2. This parameter is guaranteed but not production tested.
3. The time constant for the switch alone is of the order of 1.25ns at CL = 50pF.
4. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. 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.
