DESCRIPTION:
bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/
LS245 8-bit transceivers. The low ON resistance of the QS3245 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 74’245.
conventional logic devices.
