HIGH-SPEED CMOS 10-BIT
BUS SWITCH WITH
FLOW-THROUGH PINOUT
DESCRIPTION:
The QS3861 provides a set of ten high-speed CMOS TTL-compatible
bus switches. The low ON resistance (5Ω) of the QS3861 allows inputs to
be connected without adding propagation delay and without generating
additional ground bounce noise. The Bus Enable (BE) signal turns the
switches on.
The QS3861 is characterized for operation at -40°C to +85°C.
