HIGH-SPEED CMOS 10-BIT

QUICKSWITCH WITH

PRECHARGED OUTPUTS

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

BisopenandportBisprechargedtothebiasvoltage. ThelowONresistance

(5

Ω) 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 useful in VME bus applications.

The QS3800 is characterized for operation at -40°C to +85°C.
