DESCRIPTION:
The QS33X253 is a high-speed CMOS 24:6 (3, dual 4:1) multiplexer/
demultiplexer. The QS33X253 is a member of the MultiWidth⢠family and
is functionally compatible to three of the QuickSwitch version of the 74F253,
74FCT253, and the 74ALS/AS/LS253 Dual 4:1 multiplexers. The low ON
resistance of the QS33X253 allows inputs to be connected to outputs without
adding propagation delay and without generating additional ground bounce
noise. TTL-compatible control circuitry with "Break-before-make" feature
avoids bus contention on the demux side. This part is ideal for video
switching and four way memory bank interleaving applications.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS33X253 is characterized for operation at -40°C to +85°C.
