IDTQS3800
DESCRIPTION
The QS3800 is a 10-bit high-speed CMOS bus switch controlled by a
single enable (ON) input. When
ON
is low, the switch is on and port A is
connected to port B. When
ON
is high, the switch between port A and port
B is open and port B is precharged to the Bias voltage. The low ON resistance
(5Ω) of the QS3800 allows inputs to be connected to outputs without adding
propagation delay and without generating additional noise. The QS3800
also precharges the B port to a user-selectable bias voltage to minimize live-
insertion noise which is uselful in VME bus applications.
The QS3800 is characterized for operation at -40°C to +85°C.

NOTES:
1. This parameter is guaranteed but not production tested.
2. 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 for 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.
