• Low propagation delay
• TTL-compatible input and output levels
• Undershoot clamp diodes on all switch and control inputs
• Available in SSOP and TSSOP packages
APPLICATIONS:
• Resource sharing
• Crossbar switching
• Hot-docking
• Voltage translation (5V to 3.3V)
DESCRIPTION:
The QS316212 provides a set of 24 high-speed CMOS TTL-compatible
bus-exchange switches. The low ON resistance of the QS316212 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. The device operates
as a 24-bit bus switch or a 12-bit bus exchanger, which provides data
exchanging between the four signal ports through the data-select (S0-S2)
terminals.
The QS316212 is characterized for operation at -40°C to +85°C.
