74HC595 Serial to Parallel Shift register (DIP-16)
Texas Instruments 74HC Family use silicon gate CMOS technology to achieve operating speeds similar to the LSTTL family but with the low power consumption of standard CMOS integrated circuits. The 74HC595 chip is a high-speed Si-gate CMOS device (pin compatible with low power Schottky TTL).
- High-Speed CMOS Logic
- Operating Voltage: 2 to 6 V
- Compatibility: Input CMOS, Output CMOS
The “595” is an 8-stage serial shift register with a storage register and 3-state outputs. The shift register and storage register have separate clocks. Data is shifted on the positive-going transitions of the SHCP input. The data in each 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.
These chips are commonly used to create an additional 8 logic output ports for microcontrollers.
