The QS316211 provides a set of 24 high-speed CMOS TTL-compatible
bus switches. The low ON resistance of the QS316211 allows inputs to be
connected to outputs without adding propagation delay and without gener-
ating additional ground bounce noise. The device operates as a 24-bit bus
switch. When
1OE
is low, 1An is connected to 1Bn. When
2OE
is low, 2An
is connected to 2Bn.
The QS316211 is ideal for switching wide digital buses, 5V to 3.3V
translation, and for hot plug buffering.
The QS316211 is characterized for operation at -40擄C to +85擄C.
