74FR25900 9-Bit, 3-Port Latchable Datapath Multiplexer July 1992 Revised August 1999 74FR25900 9-Bit, 3-Port Latchable Datapath Multiplexer with 25Ω Output Series Resistors General Description 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. PINV allows inversion of the data from the C8 to A8 or B8 path. This is useful for control of the parity bit in systems diagnostics. This device includes 25Ω resistors in series with A and B Port outputs....
