HIGH-SPEED 32-BIT BUS EXCHANGE
SWITCH IN MILLIPAQ™
IDTQS34X383
FEATURES:
• 5Ω switches connect inputs to outputs

• Direct bus connect
• Live insertion capability
• Low power CMOS proprietary technology
• Bus exchange allows nibble swap
• TTL-compatible control inputs
• Available in 80-pin Millipaq package
DESCRIPTION:
The QS34X383 provides four sets of eight high-speed CMOS TTL-
compatible bus switches. The low ON resistance (5Ω) of the QS34X383
allows inputs to be connected to outputs without adding propagation delay
and without generating additional ground bounce noise. The Bus Enable
(BEx) signals turn the switches on. The Bus Exchange (BXx) signals
provide nibble swap of the AB and CD pairs of signals. This exchange
configuration allows byte swapping of buses in systems. It can also be used
as a 16-bit 2-to-1 multiplexer and to create low delay barrel shifters, etc.
The QS34X383 is characterized for operation at -40°C to +85°C.
