Working Principles

The 74LV595DB,118 is a serial-in, parallel-out shift register with output latches. It stores and transfers data in an 8-bit format. The serial data is input through the SER pin and shifted into the register on each rising edge of the SRCLK signal. The RCLK signal latches the data from the shift register into the output latch, making it available at the parallel outputs (Q7' to Q0). The OE pin controls the output enable function, allowing the outputs to be enabled or disabled. The SRCLR pin clears the shift register, resetting all the bits to a low state.

Detailed Application Field Plans
