FAST CMOS 12-BIT TRI-PORT BUS EXCHANGER
INDUSTRIALTEMPERATURERANGE
Signal
I/O
Description
A(1:12)
I/O
Bidirectional Data Port A. Usually connected to the CPU's Address/Data bus.
1B(1:12)
I/O
Bidirectional Data Port 1B. Connected to the even path or even bank of memory.
2B(1:12)
I/O
Bidirectional Data Port 2B. Connected to the odd path or odd bank of memory.
LEA1B
I
Latch Enable Input for A-1B Latch. The Latch is open when LEA1B is HIGH. Data from the A-port is latched on the HIGH to
LOW transition of LEA1B.
LEA2B
I
Latch Enable Input for A-2B Latch. The Latch is open when LEA2B is HIGH. Data from the A-Port is latched on the HIGH to
LOW transition of LEA2B.
LE1B
I
Latch Enable Input for the 1B-A Latch. The Latch is open when LE1B is HIGH. Data from the 1B port is latched on the HIGH
to LOW transition of LE1B.
LE2B
I
Latch Enable Input for the 2B-A Latch. The Latch is open when LE2B is HIGH. Data from the 2B port is latched on the HIGH
to LOW transition of LE2B.
SEL
I
1B or 2B Path Selection. When HIGH, SEL enables data transfer from 1B Port to A Port. When LOW, SEL enables data
transfer from 2B Port to A Port.
OEA
I
Output Enable for A Port (Active LOW)
OE1B
I
Output Enable for 1B Port (Active LOW)
OE2B
I
Output Enable for 2B Port (Active LOW)
