74FR25900規(guī)格書詳情
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 possible. The 74FR25900 maintains separate control of all latch enable, 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
Features
■ 25? series resistors in the port A and B outputs eliminate the need for external resistors when driving MOS inputs such as DRAM arrays
■ 9-bit data ports for systems carrying parity bits
■ Readback capability for system self checks.
■ Independent control lines for maximum flexibility
■ Guaranteed multiple output switching and 250 pF load delays
■ Outputs optimized for dynamic bus drive capability
■ PINV parity control facilitates system diagnostics
■ 74FR900 option available without output series resistors
