1 / 7 page © 1999 Fairchild Semiconductor Corporation DS011500 www.fairchildsemi.com July 1992 Revised August 1999 74FR25900 9-Bit, 3-Port Latchable Datapath Multiplexer with 25 Ω 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. Read- back of data latched from any port onto itself is also possi- ble. The 74FR25900 maintains separate control of all latch- enable, output enable and select inputs for maximum flexi- bility. 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 25 Ω resistors in series with A and B Port outputs. Resistors minimize undershoot and ringing which may damage or corrupt sensitive device inputs driven by these ports. Features s 25 Ω series resistors in the port A and B outputs elimi- nate 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 multiple output switching and 250 pF load delays s Outputs optimized for dynamic bus drive capability s PINV parity control facilitates system diagnostics s 74FR900 option available without output series resistors Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
