HIGH-SPEED CMOS BUS EXCHANGE
SWITCH WITH ACTIVE TERMINATION
(BUS HOLD)
DESCRIPTION:
The QS3388 provides ten high-speed CMOS TTL-compatible bus
switches with active termnators on the bus switch I/O pins. The low ON
resistance (5
) of the 3388 allows inputs to be connected to outputs without
adding propagation delay and without generating additional ground bounce
noise. When the switches are turned off, a low drive active termnator circuit
drives the disconnected pins to V
CC
or ground, away fromthe TTL threshold.
This prevents undriven buses fromfloating. The Bus Enable (
BE
) signal
turns the switches on. The Bus Exchange (BX) signal provides 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 five-wide 2-to-1
multiplexer and to create low delay barrel shifters, etc.
The QS3388 is characterized for operation at -40°C to +85°C.
