Working Principles

The DM74AS804BWM is based on advanced Schottky (AS) logic technology. It operates as an 8-bit shift register with output storage. The serial data input (SER) is shifted into the register on each rising edge of the shift register clock (SRCLK). The register clock (RCLK) latches the data from the shift register into the output storage on each rising edge. The output enable (OE) input controls the output state.
