• Individual controls for each bank
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• TTL-compatible control inputs
• Available in 48-pin QVSOP package
APPLICATIONS:
• Logic replacement
• Video, audio, graphics switching, muxing

DESCRIPTION:
The QS33X257 is a high-speed CMOS TTL-compatible 24:12 multi-
plexer/demultiplexer. The QS33X257 is functionally compatible to three of
the QuickSwitch version of the 74F257, 74FCT257, and the 74ALS/AS/
LS257 Quad 2:1 multiplexers. The low ON resistance of the QS33X257
allows inputs to be connected to outputs without adding propagation delay
and without generating additional ground bounce noise. This part will be
used in wide bus multiplexing where board space is at a premium.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS33X257 is characterized for operation at -40°C to +85°C.
