IDTQS3384

DESCRIPTION:

The QS3384 provides a set of ten high-speed CMOS, TTL-compatible
bus switches. The low ON resistance of QS3384 allows inputs to be
connected to outputs without adding propagation delay and without gener­ating additional ground bounce. Two banks of 5 switches are controlled by
independent Bus Enable (BE) signals.

The QS3384 is characterized for operation at -40°C to +85°C.

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
