The IC component N74F259D,623 is a high-speed, parallel-to-serial shift register with a storage register. It is part of the N74F series of IC components manufactured by Philips, which are advanced, high-speed, low-power CMOS devices.
Key features of the N74F259D,623 include:
1. Parallel-to-Serial Shifting: The IC component can shift the data from its parallel inputs to serial outputs. It has eight parallel inputs (D0 to D7) and a parallel enable input (PE) that controls the parallel-to-serial shifting operation.
2. Serial Data Output: The shifted serial data can be accessed from the Q0 serial output pin. This output provides the data output for cascading multiple N74F259D,623 components in series.
3. Storage Register: The IC component also has an 8-bit storage register that holds the parallel input data when the parallel enable input (PE) is set high. The stored data can be accessed from the Q8 to Q15 outputs and can be loaded into the shift register when PE is set low.
4. Multiplexed Data Inputs: The N74F259D,623 integrates the capability for multiplexed data inputs. When the parallel enable input (PE) is set low, the Q0 output allows selecting either the parallel inputs (D0 to D7) or the Q8 to Q15 outputs for data input
