Overview
IDTQS33X257 HIGH-SPEED CMOS QUICKSWITCH 24:12 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 24:12 MUX/DEMUX FEATURES: • • • • • • • • IDTQS33X257 DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc Bidirectional signal flow 24:12 Mux/Demux switches connect inputs to outputs 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: • • • • • The QS33X257 is a high-speed CMOS TTL-compatible 24:12 multiplexer/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.
Logic replacement Video, audio, graphics switching, muxing Hot-swapping, hot-docking Voltage translation (5V to 3.
3V) Bus funneling FUNCTIONAL BLOCK DIAGRAM S0 S2 E0 I0 A YA I1 A I0 B YB I1 B I0 C YC I1 C I0 D YD I1 D E2 I0 I YI I1 I I0 J YJ I1 J I0 K YK I1K I0 L YL I1 L S1 E1 I0E YE I1E I0 F YF I1F I0 G YG I1G I0 H YH I1H The IDT logo is a registered trademark of Integrated Device Technology, Inc.
