74HC595D

The 74HC595D from Philips is a high-speed, 8-bit shift register and latch fabricated with silicon gate C2MOS technology. It achieves high-speed operation while maintaining low power dissipation, making it suitable for various digital applications.

This integrated circuit features an 8-bit static shift register that feeds an 8-bit storage register. Shift operations occur on the positive-going transition of the SCK input, and the output register is loaded on the positive-going transition of the RCK input. The independent SCK and RCK signals allow parallel outputs to remain stable during shifting. With 3-state parallel outputs, it can be directly connected to an 8-bit bus, facilitating serial-to-parallel conversion and data receiver applications.

The 74HC595D operates over a wide voltage range of 2.0 V to 6.0 V and boasts a maximum clock frequency of 55 MHz at 5V. It exhibits low power dissipation with a maximum quiescent current of 4.0 µA at 25°C and balanced propagation delays.

Packaged in a SOIC16 format, this component is designed for surface mounting. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
