74FR900 multiplexer equivalent, 9-bit / 3-port latchable datapath multiplexer.
s 9-bit data ports for systems carrying parity bits s Readback capability for system self checks. s Independent control lines for maximum flexibility s Guaranteed multipl.
The 74FR900 is a data bus multiplexer routing any of three 9-bit ports to any other one of the three ports. Readback of data latched from any port onto itself is also possible. The 74FR900 maintains separate control of all latch-enable, output enable.
