DESCRIPTION:
Enhanced N channel FET with no inherent diode to Vcc
Ω bidirectional switches connect inputs to outputs
5Ω
Zero propagation delay, zero ground bounce
TTL-compatible input and output levels
Undershoot clamp diodes on all switch and control inputs
Available in SSOP and TSSOP packages
The QS316233 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 simultaneously. It can also be used as two 16-bit to 8-bit multiplexers or as one
32-bit to 16-bit multiplexer. SELn inputs control the data flow. TESTn inputs
control either one or two ports connection.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS316233 is characterized for operation at -40°C to +85°C.

2. Per TTL-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 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.
