IDTQS316211
Enhanced N channel FET with no inherent diode to Vcc 5 bidirectional switches connect inputs to outputs Zero propagation delay, zero ground bounce TTL-compatible input and output levels Undershoot clamp diodes on all switch and control inputs Available in SSOP and TSSOP packages
DESCRIPTION:
APPLICATIONS:
· · · · · · ·
Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Logic replacement (data processing) Power conservation Capacitance reduction and isolation Bus isolation Clock gating
The QS316211 provides a set of 24 high-speed CMOS TTL-compatible bus switches. The low ON resistance of the QS316211 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The device operates as a 24-bit bus switch. When 1OE is low, 1An is connected to 1Bn. When 2OE is low, 2An is connected to 2Bn. The QS316211 is ideal for switching wide digital buses, 5V to 3.3V translation, and for hot plug buffering. The QS316211 is characterized for operation at -40°C to +85°C.
