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.

FEATURES
• Low noise, now switching feedthrough current
• Controlled output edge rates
• High impedance PNP base inputs for reduced loading (20µA in High and Low states)
• 8-bit serial-in, parallel-out shift register with storage
• 3-state outputs
• Shift register has direct clear
• Guaranteed shift frequency-DC to 100MHz
