DESCRIPTION:
bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/
LS245 8-bit transceivers. The Output Enable (OE) signal turns the switches
on similar to the OE signal of the 74’245. The QS32245 has 25Ω series
resistors to reduce ground bounce noise.
conventional logic devices.
The QS32245 provides a set of eight high-speed CMOS TTL-compatible
QuickSwitch devices provide an order of magnitude faster speed than
The QS32245 is characterized for operation at -40°C to +85°C.
