DESCRIPTION
The 74F595 contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-State outputs. Separate clocks are provided for both the shift register and the storage register. The shift register has a direct overriding clear, serial input and serial output pins for cascading. Both the shift register and storage register clocks are positive edge-triggered. If the user wishes to connect both clocks together, the shift register state will always be one clock pulse ahead of the storage register. This device uses patented circuitry to control system noise and internal ground bounce. This is done by eliminating switching feedthrough current and controlling both Low-to-High and High-to-Low slew rates. TYPE 74F595
