description

The SN74CBT16390 is a 16-bit to 32-bit switch

used in applications in which two separate data

paths must be multiplexed onto, or demultiplexed

from, a single path. This device can be used for

memory interleaving, in which two different banks

of memory must be addressed simultaneously.

This device also can be used to connect or isolate

the PCI bus to one or two slots simultaneously.

Two output enables (OE1 and OE2) control the

data flow. When OE1 is low, A port is connected

to 1B port. When OE2 is low, A port is connected

to 2B port. When both OE1 and OE2 are low, the

A port is connected to both 1B and 2B ports. The

control inputs can be driven with a 5-V CMOS,

5-V TTL, or an LVTTL driver.
