74FR25900 Datasheet (Fairchild) - 9-Bit / 3-Port Latchable Datapath Multiplexer

74FR25900, 9-Bit / 3-Port Latchable Datapath Multiplexer

The 74FR25900 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 74FR25900 maintains separate control of all latchenable, output enable and select inputs for maximum flexibility.

74FR25900 Features

* s 25Ω series resistors in the port A and B outputs eliminate the need for external resistors when driving MOS inputs such as DRAM arrays 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
