IDTQS32X245
DESCRIPTION:
Enhanced N channel FET with no inherent diode to Vcc
5Ω bidirectional switches connect inputs to outputs
Ω
Dual '245 function
Zero propagation delay, zero ground bounce
Undershoot clamp diodes on all switch and control inputs
TTL-compatible control inputs
Available in 40-pin QVSOP package
The QS32X245 provides a set of 16 high-speed CMOS TTL-compatible
bus switches in a flow-through pinout. The low ON resistance of the
QS32X245 allows inputs to be connected to outputs without adding propa-
gation delay and without generating additional ground bounce noise. The
Output Enable (OEn) signals turn the switches on similar to the
OEn
signal
of the 74'245.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS32X245 is characterized for operation at -40°C to +85°C.
