HIGH-SPEED CMOS BUS EXCHANGE
SWITCH WITH ACTIVE TERMINATION
(BUS HOLD)
DESCRIPTION:
The QS3L388 is a low-power version of the QS3388. It provides ten high-
speed CMOS TTL-compatible bus switches with active terminators on the
bus switch I/O pins. The low ON resistance (5
)ofthe3L388allowsinputs
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 terminator circuit drives the disconnected pins to VCC
or ground, away from the TTL threshold. This prevents undriven buses from
floating. 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 QS3L388 is characterized for operation at -40°C to +85°C.
