Each device consists of an 8-flip-flop input register and an 8-bit parallel-in/serial-in, serial-out shift register. Each register is controlled by its own clock. A “low” on the parallel load input (PL) shifts parallel stored data asynchronously into the shift register. A “low” master input (MR) clears the shift register. Serial input data can also be synchronously shifted through the shift register when PL is high. Ordering Information PART NUMBER TEMP. RANGE (oC) PACKAGE...
