Description
The 74HC595D is a high speed 8-BIT SHIFT REGISTER/LATCH fabricated with silicon gate C2MOS technology. It achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The 74HC595D contains an 8-bit static shift register which feeds an 8-bit storage register. Shift operation is accomplished on the positive going transition of the SCK input. The output register is loaded with the contents of the shift register on the positive going transition of the RCK input. Since RCK and SCK signal are independent, parallel outputs can be held stable during the shift operation. And, since the parallel outputs are 3-state, it can be directly connected to 8-bit bus. This register can be used in serial-to-parallel conversion, data receivers, etc.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
