IDTQS316209
DESCRIPTION:
The QS316209 provides a set of 18 high-speed CMOS TTL-compatible
bus-exchange switches. The low ON resistance of the QS316209 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. This device operates
as an 18-bit bus switch or a 9-bit bus exchanger, which provides data
exchanging between the four signals through the data-select (S0-S2)
terminals.
The QS316209 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 time constant for the switch alone is of the order of 0.25ns for C
L
= 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.
