8-bit Latch/Shift Register
ADE-205-515 (Z)
1st. EditionSep. 2000
Description
The HD74HC597 consists of an 8-bit storage latch feeding a parallel-in, serial-out 8-bit shift register. Boththe storage register and shift register have positive-edge triggered clocks. The shift register also has directload (from storage) and clear inputs.
