74LV595PW,118

The 74LV595PW is a 8 stage serial Shift Register with a storage register and 3-state outputs. It is a low-voltage Si-gate CMOS device and is pin and functionally compatible with the 74HC595 and 74HCT595. Data is shifted on the positive-going transitions of the SHCP input. The data in the shift register is transferred to the storage register on a positive-going transition of the STCP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register. The shift register has a serial input (DS) and a serial output (Q7S) for cascading the device. It is also provided with an asynchronous reset input MR\ (active low) for all 8 shift register stages. The storage register has 8 parallel 3-state bus driver outputs. Data in the storage register appears at the output whenever the OE\ is low.

• Has a shift register with direct clear
