IDTQS3244
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• 25Ω bidirectional switches connect inputs to outputs
• Pin compatible with 74F244, 74FCT244, and 74FCT244T
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Available in QSOP, SOIC, and TSSOP packages
APPLICATIONS:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Power conservation
• Capacitance reduction and isolation
• Logic replacement (data processing)
• Clock gating
• Bus switching and isolation
FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3244 provides a set of eight high-speed CMOS TTL-compatible
bus switches in a pinout compatible with 74FCT244, 74F244, 74ALS/AS/
LS244 8-bit drivers. The low ON resistance (5Ω) of the 3244 allows inputs
to be connected to outputs without adding propagation delay and without
generating additional ground bounce noise. The two enable (xG) signals
turn the switches on similar to the xG signals of the 74’244.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS3244 is characterized for operation at -40°C to +85°C.
