Enhanced N channel FET with no inherent diode to Vcc
2.5鈩?bidirectional switches connect inputs to outputs
Pin compatible with 74F245, 74FCT245, and 74FCT245T
Zero propagation delay, zero ground bounce
Undershoot clamp diodes on all switch and control inputs
TTL-compatible control inputs
Available in SOIC and QSOP Packages
IDTQS3R245
DESCRIPTION:
The QS3R245 provides a set of eight high-speed CMOS TTL-compatible
bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/
LS245 8-bit transceivers. The low ON resistance of the QS3R245 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. The Output Enable (OE)
signal turns the switches on similar to the
OE
signal of the 74鈥?45. The low
ON resistance of QS3R245 makes it ideal for PCI hot docking applications.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS3R245 is characterized for operation at -40擄C to +85擄C.
